BackgroundEphippidae fish are characterized by a discoid shape with a very small visceral cavity. Among themPlatax orbicularishas a high economic potential due to its flesh quality and flesh to carcass ratio. Nonetheless, the development of its aquaculture is limited by high mortality rates, especially due toTenacibaculum maritimuminfection, occurring one to three weeks after the transfer of fishes from bio-secure land-based aquaculture system to the lagoon cages for growth. Among the lines of defense against this microbial infection, the gastrointestinal tract (GIT) is less studied. The knowledge about the morphofunctional anatomy of this organ inP. orbicularisis still scarce. Therefore, the aims of this study are to characterize the GIT in non-infectedP. orbicularisjuveniles to then investigate the impact ofT. maritimumon this multifunctional organ.MethodsIn the first place, the morpho-anatomy of the GIT in non-infected individuals was characterized using various histological techniques. Then, infected individuals, experimentally challenged byT. maritimumwere analysed and compared to the previously established GIT reference.ResultsThe overlapped shape of the GIT ofP. orbicularisis probably due to its constrained compaction in a narrow visceral cavity. Firstly, the GIT was divided into 10 sections, from the esophagus to the rectum. For each section, the structure of the walls was characterized, with a focus on mucus secretions and the presence of the Na+/K+ATPase pump. An identification key allowing the characterization of the GIT sections usingin totohistology is given. Secondly, individuals challenged withT. maritimumexhibited differences in mucus type and proportion and, modifications in the mucosal and muscle layers. These changes could induce an imbalance in the trade-off between the GIT functions which may be in favour of protection and immunity to the disadvantage of nutrition capacities.

Individuals were collected in five sampling units (SUs) located in latitudes between 2 degrees S and 27 degrees S, southernmost limit of species distribution. The COI sequences from Brazilian sampling units were compared with eight sequences from the Gulf of Mexico and Caribbean, resulting in no significant genetic differences (K2P < 0.32%). On the contrary, pairwise F-ST analysis based on D-loop datasets from the five SUs indicated divergence between Tropical and Subtropical clades of SW Atlantic C. faber. The SAMOVA approach was consistent with this divergence and revealed maximal variance among groups (63.59%) when two clades are simulated (k = 2), setting apart Tropical and Subtropical SUs. Demographic analyses support the hypothesis of population expansion, both for Tropical and Subtropical clades. Moreover, Subtropical population size increase was dated after the Tropical clade reached the demographic stability, around 10 kyr ago, during the beginning of interglacial Pleistocene Holocene transition. The historical demographic results, along with the lower genetic diversity and the star shaped haplotype network of the Subtropical clade corroborate an ancient scenario of the species' adaptive radiation southward.

Lobotes, Datnioides and Hapalogenys are assigned to a newly defined Acanthuriformes on the basis of their pattern of tooth replacement (termed posterolateral tooth replacement), where new teeth form at the posterolateral ends of series. Posterolateral tooth replacement is shown to be a synamorphy of the order. The order is expanded to include Chaetodontidae, Pomacanthidae, Drepaneidae, Ephippidae, Leiognathidae, Antigonia, Scatophagidae and Capros, along with the more traditional members, Siganidae, Luvaridae, Zanclidae and Acanthuridae. Three-item analysis of 63 adult and larval morphological characters yields two optimal trees that differ only in the relative positions of Capros and Siganidae. The intersection tree of the two optimal trees is: (((Hapalogenys (Datnioides, Lobotidae)) (Pomacanthidae (Drepaneidae (Chaetodontidae (Ephippidae (Leiognathidae (Scatophagidae (Antigonia (Siganidae, Capros (Luvaridae (Zanclidae, Acanthuridae)))))))))))). This cladogram is compared with recent phylogenies based on analyses of sequence data, and few differences are found once the weakly-supported interior nodes of the latter are collapsed. Aside from expansion of the Acanthuriformes, the following classification changes are proposed in order to reflect the phylogenetic relationships: redefinition of the Lobotidae to include Lobotes, Datnioides and Hapalogenys; separate families for Antigonia and Capros (Antigoniidae and Caproidae, respectively); continued recognition of Drepaneidae (often considered a synonym of Ephippidae). The larvae of Capros aper are illustrated to show features overlooked in earlier descriptions.

This thesis explores the taxonomy, systematics and phylogenetic status of the family Faustulidae from corallivorous fishes in the Tropical Indo-west Pacific (TIWP). The main study is based on the parasitological examination of 2,901 individual coral reef fishes from six major TIWP localities: Ningaloo Reef, Western Australia; Palau; Lizard Island, Swain Reefs complex and Heron Island (all Queensland); and French Polynesia.Faustulidae are mainly parasites of the intestine of marine teleosts and are characterised by a spiny tegument, a canalicular seminal receptacle and a posterior opening Laurer’s canal. Of the 12 genera that belong to this family, the largest, and the main focus of this study, is Paradiscogaster Yamaguti, 1934. Before this study, Paradiscogaster comprised 24 species distributed in the Indo-west Pacific and infecting 13 families of fish. Of these, corallivorous fishes from the family Chaetodontidae had the largest number of Paradiscogaster species, followed by fishes, with a diverse diet, from Monacanthidae and Ostraciidae.The results from this study are structured first as three taxonomic chapters describing new species from this genus; I described and published six new Paradiscogaster species from Chaetodontidae and Ephippidae, and a further five new species not yet published: two new species corresponding to the Paradiscogaster eniwetokensis complex on the GBR, two from Palau, two from Ningaloo Reef and one from French Polynesia. This is followed by an overall phylogenetic study of the family, a study of trematodes from non-chaetodontid corallivorous fishes from the Great Barrier Reef (including the description of a new species from Fellodistomidae) and finally an account of a search for larval trematodes in coral.For the analysis of the phylogeny of Faustulidae, 28S rDNA sequences were obtained from ten Faustulidae species. These were aligned and analysed relative to other faustulids and species of key families of interest. The complete analysis included sequences for 35 species of Faustulidae, Fellodistomidae, Gymnophallidae, Tandanicolidae, and Zoogonidae (with Hemiuridae as an outgroup) and showed that some Faustulidae and Zoogonidae form a clade, but that relationships within the clade are not well-resolved. More sequences will be required to determine whether Faustulidae should be restructured relative to the Zoogonidae as previously suggested, and also to determine the taxonomic position of three species of Faustulidae, Pseudobacciger cheneyae and two species of Bacciger, which formed a clade quite separate from all other Faustulidae. This chapter also analyses the ITS2 rDNA sequences of the family, incorporating new sequences and published sequences available from GenBank. The genus Paradiscogaster incorporates a clade formed by species that infect corallivorous chaetodontids and another clade from non-chaetodontids.To determine the implications of corallivory on the trematode fauna of non-chaetodontid corallivores, I studied several obligate corallivores that have not been previously sampled, including species of Blenniidae (Exallias brevis), Gobiidae (Gobiodon citrinus), Labridae (Labropsis australis and Labrichthys unilineatus), Monacanthidae (Amanses scopas and Oxymonacanthus longirostris) and Tetraodontidae (Arothron nigropunctatus). No infections of Paradiscogaster species were found but a new species (Fellodistomidae: Prudhoeus) is described from Amanses scopas and Exallias brevis from Heron Island, Queensland. Clearly, exploitation of these corallivores by trematodes has been much less extensive than in the chaetodontids.Many species of chaetodontid fishes reported as obligate corallivores are heavily infected by faustulids, suggesting that the ingestion of the parasites in intermediate stages is through the diet, coral polyps or a symbiont associated with coral polyps. I thus looked for metacercariae in acroporid corals (the most abundant dietary item in obligate corallivores, representing 97–98% of the diet), examining between 4500-9000 coral polyps from 90 fragments, utilizing varied techniques to extract the polyps, but without a positive finding. This outcome means that the transmission mechanisms of these parasites remain unexplained. In terms of biogeography and host-specificity, the results show that the highest known concentration of Faustulidae species is found on the GBR, where the host-specificity is higher than in other localities. The richness of Paradiscogaster species varied among TIWP sites, having the GBR as the richest known area and lower in Palau, New Caledonia, Ningaloo Reef and French Polynesia. However, the host-specificity (specifically of P. sasali) reduced in the extremities partially isolated and remote areas of the TIWP and Paradiscogaster species were found infecting a wide variety of hosts, perhaps increasing the chance of reproduction and dispersion.A better understanding of the life cycles of these parasites, particularly the intermediate host specificity, will contribute to an understanding of the biogeography of these parasites and will contribute to an explanation of why these parasites are not present in all localities in the TIWP, even when appropriate definitive hosts are present.

We used the cytochrome oxidase subunit I (coI) gene DNA to barcode 117 endemic Gulf and cosmopolitan Indo-West Pacific fish species belonging to 54 families and 13 orders. Novel DNA barcodes were provided for 18 fish species (Trachinocephalus sp., Nematalosa sp., Herklotsichthys lossei, Upeneus doriae, Trachurus indicus, Apogonichthyoides taeniatus, Verulux cypselurus, Favonigobius sp., Suezichthus gracilis, Sillago sp., Brachirus orientalis, Pegusa sp., Lepidotrigla bispinosa, Lepidotrigla sp., Grammoplites suppositus, Hippichthys sp., Paramonacanthus sp. and Triacanthus sp.). The species delimitation analysis, conducted with Poisson tree processes- Bayesian PTP (PTP-bPTP) and nucleotide-divergence-threshold (NDT) models), found 137 and 119 entities respectively. Overall, NDT method, neighbour-joining species tree and the prior taxonomic assessment provided similar results. Among the 54 families considered, only 10 (Ariommatidae, Ephippidae, Leiognathidae, Nemipteridae, Plotosidae, Pomacanthidae, Pomacentridae, Priacanthidae and Rachycentridae) showed the occurrence of molecular diagnostic pure characters. The DNA barcoding database developed during this study will help ichthyologists to identify and resolve the taxonomic ambiguities they may encounter with the fishes occurring in The Gulf and throughout the region.

Os resultados mais importantes desta tese foram: (1) próximo ao seu limite sul de distribuição C. faber tem uma longevidade de 17 anos; (2) o dimorfismo sexual no crescimento não foi evidente e a razão sexual (machos: fêmeas) foi de 1: 1,17; (3) a espécie apresenta crescimento assintótico que se ajusta a função crescimento de von Bertalanffy, onde os parâmetros estimados para todos os indivíduos coletados aos 25°S (Estado do Paraná) foram: L = 508,81 mm, k = 0,22 ano-1 e t0 = -0,05 ano; (5) a espécie apresenta uma estratégia de desova parcelada com pico reprodutivo entre outubro e janeiro em latitudes subtropicais (25°S); (6) regiões estuarinas são importantes para a reprodução da espécie que, aparentemente, forma agregações reprodutivas nestas áreas; (7) as fêmeas gastam aproximadamente seis meses a mais que os machos para atingir a maturidade e são capazes de desovar pouco antes do seu segundo aniversário; (8) a forma e a química dos otólitos revelaram que a conectividade entre a população de C. faber na região do Espírito Santo (20°S) com as populações do sul (> 22°S) é limitada; (9) a presença de grupos semi-discretos espacialmente estruturados foi evidente entre 23°S e 27°S (Rio de Janeiro e Santa Catarina); (10) as razões de Sr/Ca e Mn/Ca ao longo dos marcos cronológicos nos otólitos de C. faber indica que a maioria dos indivíduos usa as regiões estuarinas na fase juvenil e migra para águas costeiras de maiores salinidades na fase adulta. Para fins de manejo pesqueiro, os nossos resultados sugerem que o defeso durante o pico reprodutivo e a proibição das capturas de indivíduos menores que 25 cm de comprimento total podem ser usados para a gestão do estoque de C. faber no Sul do Brasil; As unidades populacionais de C. faber na costa Sudeste e Sul do Brasil devem ser consideradas como diferentes estoques para fins de gestão pesqueira. No entanto, o grau de mistura e a contribuição que cada unidade populacional identificada recebe de fontes distantes de recrutamento são desconhecidas e exigem estudos adicionais. Por fim, os resultados reforçam a importância da conservação dos sistemas estuarinos que contribuem expressivamente para a manutenção das populações de C. faber no Oceano Atlântico Sudoeste. Abstract: In this doctoral thesis some life-history traits of Atlantic spadefish, Chaetodipterus faber, in southern Brazil and the stock structure in the main fishery areas of the species in the Southwest Atlantic Ocean were investigated. The most important findings of this thesis were: (1) C. faber has a 17-year longevity close to its southern distributional limit; (2) sexual growth dimorphism was not evident and the male:female sex ratio was 1:1.17; (3) the species displayed asymptotic growth. Fitted von Bertalanffy growth function estimates for all individuals collected at 25°S (Paraná State) were L = 508.81 mm, k= 0.22 year-1, and t0= - 0.05 year; (4) the species is a batch spawner with a main reproduction period from October to January in subtropical latitudes at 25°S; (5) estuarine areas are important for C. faber reproduction that most likely exhibits a seasonal movement for spawning aggregation purposes; (6) females mature approximately 6 months later than males and are capable of spawning just prior to two years old; (7) the otolith shape and chemistry signatures indicated that connectivity between the population of C. faber in the Espírito Santo region (20°S) with the southern populations (>22°S) is limited; (9) the presence of spatially structured semidiscrete groups between 23°S and 27°S (Rio de Janeiro and Santa Catarina states) was evidenced; (8) the Sr/Ca and Mn/Ca ratios along chronological landmarks within the C. faber otoliths indicated that most individuals use the estuarine regions in the juvenile stage and thereafter migrate as adults to the open sea. To management proposes, the hereby results suggest that fishery closures during the spawning season and fishing size restrictions should be used to manage the C. faber stock in southern Brazil; The population-units should be regarded as different stocks for fisheries management purposes. However, at present, the degree of intermixing and the contribution that each local population identified receives from distant recruitment sources is unknown and demands further studies. Moreover, the current data reinforce the importance of estuarine systems conservation that plays a significant contribution as a nursery area for C. faber in southeastern-south Brazil.

The current checklist provides for each species of the Red Sea its records in the Gulf of Suez, Gulf of Aqaba, Red Sea main basin and its general distribution.This new checklist of Red Sea fishes enumerates 1207 species, representing 164 families. Of these, 797 species were recorded from the Gulf of Aqaba and 339 from the Gulf of Suez. The number of species from the Gulf of Suez is evidently lower than the actual number not including 27 Lessepsian (Red Sea) migrants to the Mediterranean that most likely occur in the Gulf. The current list includes 73 species that were newly described for science since the last checklist of 2010. The most specious Osteichthyes families are: Gobiidae (134 species), Labridae (66), Apogonidae (59), Serranidae (including Anthiadinae) (44), Blenniidae (42), Carangidae (38), Muraenidae (36), Pomacentridae (35), Syngnathidae (34), Scorpaenidae (24) and Lutjanidae (23). Among the families of Chondrichthyes, the most specious families are the Carcharhinidae (18 species) and Dasyatidae (11). The total number of endemic species in the Red Sea is 174 species, of these, 34 species are endemic to the Gulf of Aqaba and 8 to the Gulf of Suez.

A new species of Neorhadinorhynchus (Acanthocephala: Cavisomidae), N. basrahiensis, is described from the small intestine of the longfin batfish Platax teira Forsskal, 1775, from Iraqi marine waters. The new species is distinguished from its congeners by the proboscis armature of 12 rows of 8–10 hooks, the largest hooks being up to a third larger than the largest hooks previously described for the genus. It is first record of the genus in the Ephippidae and from Iraqi marine waters; the fourth species of the genus Neorhadinorhynchus to be described from the Indian Ocean.

Adult C. faber were collected in euhaline environments from five Brazilian states (Espirito Santo, Rio de Janeiro, Sao Paulo, Parana, and Santa Catarina) and otolith elemental ratios (Sr/Ca, Ba/Ca and Mn/Ca) were recorded from the core to otolith edge. The otolith Sr/Ca pattern demonstrated that most fish (95%) spend the first year of life within estuaries, but then move toward seawater; migrations between estuarine and marine environments appear not to occur after estuarine egress. Evidence of marine residence throughout life was found in only 5% of individuals. Moreover, the general otolith Sr/Ca pattern indicated that spawning occurs mainly in coastal waters adjacent to estuaries. Additionally, otolith element/Ca ratios suggest that adult C. faber display seasonal migrations between inshore and offshore waters, which corroborate with monthly fishery C. faber landings. This finding implies that artisanal and industrial fisheries require a shared quota. The inferential scope of seasonal movements was sometimes limited by the lack of water chemistry data and unknown relative effects of environmental and physiological factors. Thus additional research is required to evaluate the connectivity between environments, a pre-requisite for effective fisheries conservation and management of C. faber.

In the present study, totally 162 species of coral reef associated fishes, belonging to 17 orders, 64 families and 94 genera have been recorded in Cuddalore, Parangipettai and Nallavadu reefs. The study was conducted for a period of two years from January 2012 to December 2013. In Cuddalore, during 2012 a total number of 138 species of coral reef associated fishes belonging to 83 genera, 55 families and 17 orders were recorded, and in 2013, as many as 131 species belonging to 76 genera, 51 families and 14 orders were recorded. In Parangipettai, 127 species of coral reef associated fishes belonging to 78 genera, 48 families and 13 orders were recorded during 2012, and in 2013, 120 species belonging to 73 genera, 45 families and 12 orders were recorded. In Nallavadu, 117 species of coral reef associated fishes were recorded in 2012. These belong to 77 genera, 51 families and 17 orders; whereas, in 2013, totally 112 species belonging to 75 genera, 52 families and 17 orders were recorded. Considering the family-wise distribution, families such as Carangidae, Serranidae and Lutjanidaeare were found dominant with 22, 15 and 12 species respectively, followed by Haemulidae and Mullidae (6 species each), Acanthuridae, Nemipteridae, Siganidae and Synodontidae (4 species each), Clupeidae, Ephippidae, Lethrinidae and Sphyraenidae (3 species each) and other families with less than three species. Shannon Wiener diversity index recorded was in the range of 5.775 (during pre-monsoon period in 2013 at Cuddalore) -4.326 (during summer in 2012 at Nallavadu). In Margalef’s richness index, the maximum of 13.74 was recorded in Cuddalore during pre-monsoon in 2012 and the minimum of 7.975 in Nallavadu during monsoon in 2013. In taxonomic diversity among the three regions, the maximum of 55.86 was recorded in Parangipettai and minimum (51.55) was found in Nallavadu during the pre-monsoon period in 2012. In phylogenetic diversity the maximum of 4217 Cuddalore and a minimum of 2467 were recorded in Nallavadu during summer in 2013. The higher values recorded in all diversity indices clearly showed the good health of the coral reef environment in the study area.

No. of bitstreams: 0 Previous issue date: 2017-01-01 The weakness of physical barriers in the marine environment and the dispersal potential of fish populations have been invoked as explanations of the apparent karyotype stasis of marine Percomorpha, but several taxa remain poorly studied cytogenetically. To increase the chromosomal data in this fish group, we analyzed cytogenetically three widespread Atlantic species from distinct families: Chaetodipterus faber Brous-sonet, 1782 (Ephippidae), Lutjanus synagris Linnaeus, 1758 (Lutjanidae) and Rypticus randalli Courtenay, 1967 (Serranidae). The three species shared a karyotype composed of 2n=48 acrocentric chromosomes, single nucleolus organizer regions (NORs) and reduced amounts of centromeric heterochromatin. A single NOR-bearing pair was identified in all species by physical mapping of 18S rDNA while non-syntenic 5S rRNA genes were located at centromeric region of a single pair. The similar karyotypic macrostructure observed in unrelated groups of Percomorpharia reinforces the conservative karyoevolution of marine teleosteans. Nonetheless, the species could be differentiated based on the pair bearing ribosomal cistrons, revealing the importance of microstructural analyses in species with symmetric and stable karyotypes.

This publication is part of a series prepared with the purpose to constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. Here we present the results of 15 morphological features and six shape indices for 33 Perciformes species of 20 families. Whenever available in out collection, three otoliths of each species were illustrated and photographed. The frequency of occurrence of each feature was calculated inside and among total length classes being the differences analyzed through multiple χ2 tests (significance level 0.05). Based on otoliths measurements, six shape indices values were obtained being the minimum, maximum, mean and standard deviations values presented. RESUMO Esta publicação é a continuação de uma série que deverá resultar em um Atlas de Otólitos de Teleósteos da Região Sudeste-Sul brasileira. Aqui apresentamos os resultados de análises morfológicas relativas a 15 características e seis índices usualmente utilizados para a caracterização dessas estruturas. Neste estudo são apresentados os raesultados obtidos para 33 espécies de Percifomes de 20 famílias. Sempre que possível, foram desenhados e fotografados três otólitos de cada espécie. A frequência de ocorrência de cada característica morfológica foi calculada por classes de comprimento total (TL) e para toda a amostra, sendo as diferenças, dentro de cada classe e, ao longo do desenvolvimento do peixe, analisadas por meio de testes de χ2 múltiplo (nível de significância 0,05). A partir de medidas dos otólitos, foram calculados valores de seis índices de forma, sendo aqui apresentados seus valores mínimo, máximo, média e desvio padrão.

Based on light and scanning electron microscopical studies, the following nine species of Philometridae (Nemaoda: Dracunculoidea) are described from female worms parasitizing marine perciform fishes belonging to six families off the northern coast Australia (near Darwin): Philometra australiensis sp. n. from the swimbladder of the king threadfin Polydactylus macrochir (Gunther) (Polynemidae); P. epinepheli Dewi et Palm, 2013 from the operculum of the orange-spotted grouper Epinephelus coioides (Hamilton) (Serranidae); Philometra johnii Moravec et Ali, 2013 from the gonad of the croaker Johnius sp. (Sciaenidae); P. macrochiri sp. n. from the sensory fin of P. macrochir; P. zabidii sp. n. from the ovary of the ninespine batfish Zabidius novemaculatus (McCulloch) (Ephippidae); Philometra sp. 1 and Philometra sp. 2 from the ovary of the Spanish flag snapper Lutjanus carponotatus (Richardson) (Lutjanidae) and the silver grunt Pomadasys argenteus (Forsskal) (Haemulidae), respectively; Philometroides eleutheronemae Moravec et Manoharan, 2013 from the ovary of the fourfinger threadfin Eleutheronema tetradactylum (Shaw) (Polynemidae); and Spirophilometra endangae Dewi et Palm, 2013 from the pectoral fins of E. coioides. The new species P. australiensis is characterized mainly by the structure of the cephalic end, 14 minute cephalic papillae, absence of caudal projections and body length of gravid female (67 mm), P. macrochiri by the presence of a conspicuously large anterior oesophageal bulb, 14 very small cephalic papillae and the truncated posterior end of body without any caudal projections, whereas P. zabidii is characterized by the presence of distinct caudal projections, the number (14) and larger size and arrangement of cephalic papillae, a poorly developed anterior oesophageal inflation, the body length (114 mm) and the host family (Ephippidae). All above-mentioned species were recorded from Australian waters for the first time.

Summary The absolute light sensitivities, temporal properties, and spectral sensitivities of the visual systems of three mid-Atlantic temperate reef fishes (Atlantic spadefish [Ephippidae: Chaetodipterus faber], tautog [Labridae: Tautoga onitis], and black sea bass [Serranidae: Centropristis striata]) were studied via electroretinography (ERG). Pelagic Atlantic spadefish exhibited higher temporal resolution but a narrower dynamic range than the two more demersal foragers. The higher luminous sensitivities of tautog and black sea bass were similar to other benthic and demersal coastal mid-Atlantic fishes. Flicker fusion frequency experiments revealed significant interspecific differences at maximum intensities that correlated with lifestyle and habitat. Spectral responses of the three species spanned 400–610 nm, with high likelihood of cone dichromacy providing the basis for color and contrast discrimination. Significant day-night differences in spectral responses were evident in spadefish and black sea bass but not tautog, a labrid with characteristic structure-associated nocturnal torpor. Atlantic spadefish responded to a wider range of wavelengths than did deeper-dwelling tautog or black sea bass. Collectively, these results suggest that temperate reef-associated fishes are well-adapted to their gradient of brighter to dimmer photoclimates, representative of their unique ecologies and life histories. Continuing anthropogenic degradation of water quality in coastal environments, at a pace faster than the evolution of visual systems, may however impede visual foraging and reproductive signaling in temperate reef fishes.
