Abstract

A specimen of common thresher shark Alopias vulpinus (Bonnaterre 1788) was caught in a fishing net in the waters off Piran (Gulf of Trieste, northern Adriatic Sea). It was a juvenile male with a total length of 2841 mm. In recent decades, other cases of juvenile specimens of common thresher shark have been recorded in Slovenian coastal waters. Despite the drastic decline in the population of this species, thresher shark continues to be caught in local Adriatic fisheries.

Abstract

Simple Summary: Clingfish are small fish species that spend most of their time hiding in various shelters on the seabed. Due to this way of life, their ecology is little known, although they are important for the ecosystem. The aim of the research was to investigate the diet of three clingfish species (Lepadogaster lepadogaster, L. candolii, and Apletodon incognitus) using a method based on the analysis of prey from their faeces. The results show that crustaceans are the most important prey for all three species, although the composition of the diet also depends on various factors, such as the size of the fish and the prey, the behaviour of the fish, the home range of the fish, and the availability of food. These results provide us with important information about the participation of clingfish in the food web and deepen our knowledge of the fish's diet and the factors that influence it. The results also show that the occurrence of predatory fish depends on the presence of their prey. Cryptobenthic fish are small benthic fish species that normally live in various hiding places. Due to their large numbers, they are very important for energy transfer to higher trophic levels. However, due to their small size and hidden lifestyle, knowledge about them and their ecology, including their diet, is still limited. Using a non-destructive method based on faecal pellets, we investigated the diet of three clingfish species, Lepadogaster lepadogaster, L. candolii, and Apletodon incognitus, in the shallow northern Adriatic Sea. To better understand the results, we studied the fauna of potential prey in the habitats of the fish studied and also took fish specimens to observe their behaviour in the laboratory. The three species feed predominantly on crustaceans, particularly amphipods, copepods, and decapods. The proportion of the different taxa in the diet depends on the species of clingfish, the size of the specimens, and the size of the prey. In addition, the behaviour of the fish, the home range of the specimens, and the availability of food played an important role. The presence of certain crustacean groups in the environment also determines the occurrence of clingfish of different species and sizes. [ABSTRACT FROM AUTHOR]

12. On the presence of the less known arminid nudibranch Dermatobranchus rubidus (Gould, 1852) in the Adriatic Sea

Abstract

Two cases of the occurrence of the alien heterobranch species, Dermatobranchus rubidus (Gould, 1852) are reported for the Adriatic Sea. The first record originates from June 2019 from the island of Brač (Croatia, Middle Adriatic Sea), when a specimen was found during the collection of clams, while the second specimen was sighted at Fiesa (Gulf of Trieste, Northern Adriatic Sea) in October 2023, photographed on coarse sand bottom. These are the first records for the Adriatic Sea and indications of the possible establishment of this species in the Mediterranean Sea. Due to its cryptic behaviour and perhaps nocturnal habits, it is difficult to assess whether the species has been overlooked so far or whether it is extending its distribution in the Mediterranean., U Jadranskom moru zabilježena su dva nalaza strane vrste puža stražnjoškržnjaka, Dermatobranchus rubidus (Gould, 1852). Prvi nalaz je iz lipnja 2019., s otoka Brača (Hrvatska, srednji Jadran), kada je jedan primjerak pronađen tijekom sakupljanja školjkaša, dok je drugi primjerak uočen u Fiesi (Tršćanski zaljev, sjeverni Jadran) u listopadu 2023. te je fotografiran na grubo pjeskovitom dnu. Ovo su prvi nalazi za Jadran, koji ukazuju na moguću uspostavu populacije ove vrste u Sredozemnom moru. Zbog svog kriptičnog ponašanja i pretpostavljenog noćnog načina života, teško je sa sigurnošću utvrditi povećava li se rasprostranjenost ove vrste u Sredozemnom moru ili jednostavno do danas nije bila uočena.

Abstract

High abundances of gelatinous zooplankton (GZ) can significantly impact marine ecosystem by acting as both sink and source of organic matter (OM) and nutrients. The decay of GZ bloom can introduce significant amount of OM to the ocean interior, with its variability influenced by GZ life traits and environmental factors, impacting microbial communities vital to marine biogeochemical cycles. The invasive ctenophores Mnemiopsis leidyi has formed massive blooms in the northern Adriatic Sea since 2016. However, the variability in the chemical composition and egg production of blooming populations, as well as the role of environmental factors in governing this variability, remains largely unknown. Our analysis of biometry, chemical composition, and fecundity of M. leidyi sampled in the Gulf of Trieste in 2021 revealed stable carbon and nitrogen content throughout bloom development, with no significant correlation with seawater temperature, salinity, oxygen, and chlorophyll a concentration. Although the studied population exhibited homogeneity in terms of biometry and chemical composition, the number of produced eggs varied substantially, showing no clear correlation with environmental variables and being somewhat lower than previously reported for the study area and other Mediterranean areas. We observed a positive correlation between the wet weight of individuals and the percentage of hatched eggs, as well as a significant positive correlation between the percentage of hatched eggs and ambient seawater temperature. Additionally, we noted that the speed of hatching decreased with decreasing seawater temperature in autumn, corresponding to the end of M. leidyi bloom. [ABSTRACT FROM AUTHOR]

Abstract

The authors studied the structure of the coastal fish assemblage in a temperate coral reef within a marine protected area in order to provide a baseline information on the occurrence and temporal distribution of fish and to highlight the importance of the coral reef to ichthyofauna. The coastal fish assemblage was investigated at two sites in Veliko jezero (Mljet National Park) in the southern Adriatic Sea with a non-destructive SCUBA visual technique in the period from 2013 to 2021. Altogether, 38 fish taxa were recorded on the right bank (coral reef) and 36 species on the left bank. The presence of the coral reef at a depth range between 9 m to 12 m is the main factor differentiating the fish fauna in these two areas, which are otherwise governed by the same environmental factors. At the coral reef a decrease in fish diversity was discovered with a steady regression from 2013 to 2021. [ABSTRACT FROM AUTHOR]

Abstract

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).

Abstract

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).

Abstract

A specimen of common thresher shark Alopias vulpinus(Bonnaterre 1788) was caught in a fishing net in the waters off Piran (Gulf of Trieste, northern Adriatic Sea). It was a juvenile male with a total length of 2841 mm. In recent decades, other cases of juvenile specimens of common thresher shark have been recorded in Slovenian coastal waters. Despite the drastic decline in the population of this species, thresher shark continues to be caught in local Adriatic fisheries.

Abstract

Uzgajališta riba otpuštaju velike količine organske tvari u okolno more, što negativno utječe na ekosustav. Te hranjive tvari pobuđuju cvjetanje fitoplanktona i makroalga, što smanjuje prodor svjetlosti u morski okoliš. U zadnjih nekoliko godina pojava ljepljivih agregata alga u bentosu postao je sve veći problem duž obale Jadrana. Najčešće vrste su nitaste, brzorastuće bentoske alge iz razreda Chrysophyceae, Nematochrysopsis marina (Feldmann) Billard i Chrysonephos lewisii (W.R. Taylor), te smeđa alga Acinetospora crinata (Carmichael) Sauvageau. Otok Ravu okružuje 5 većih uzgajališta riba. Istraživanja se na tom području provode 20 godina, primarno vezana uz utjecaj marikulrura na bentoske organizme. Zbog povišene temperature mora i cvjetanja alga, morski bentos prekriven je tijekom proljeća i ljeta, debelim slojem alga. Znatno povećanje temperature mora smatra se glavnim razlogom koji je doveo do cvjetanja mora i 44 stvaranja algalne sluzi. Od 2001. do 2021. više od 30% kolonija crvene gorgonije Paramuricea clavata na istraživanim postajama uginulo je od posljedica “gušenja” cvjetanjem alga. Znatno se smanjila gustoća livada morske cvjetnice Posidonia oceanica, a stradale su i ostale sesilne vrste poput spužvi i koralja zbog prekrivenosti obraštajem alga, nemogućnosti hranjenja i anoksije nastale bakterijskom razgradnjom. Istraživanje pokazuje da se kavezi za uzgoj nikako ne bi smjeli postavljati u kanale i uvale, što na žalost nije slučaj sa Jadranskim morem.

47. Klimatske promjene i stanje crvene gorgonije (Paramuricea clavata (Risso, 1826)) u zaštićenim područjima istočnog Jadrana

Abstract

Nedavne smrtnosti sesilnih morskih organizama povezane su s povišenim temperaturama mora kao posljedica globalnih klimatskih promjena. Ovi događaji su zahvatili tridesetak vrsta beskralježnjaka iz pet različitih skupina (spužve, žarnjaci, mekušci, mahovnjaci i mješčićnice) duž istočne Jadranske obale. Najviše pogođene vrste bile su spužve i žarnjaci. Zadnje dvije godine proučavan je utjecaj masovne smrtnosti na populacije crvene gorgonije Paramuricea clavata (Risso, 1826) u zaštićenim morskim područjima Jadrana (PP Telašćica i NP Kornati). Većina ispitanih populacija ima oko 50% zahvaćenih kolonija različitog stupnja oštećenja (uginulih, teških ili manjih oštećenja). Smanjenje populacija uglavnom je posljedica smrtnosti kolonija zbog većih ozljeda tkiva i zato što „novačenje“ (razvoj novih kolonija) nije nadoknadilo smrtnost. Evidentna je velika varijabilnost u stopama smrtnosti i gubitka tkiva ovisno o lokacijama istraživanja. Utjecaj na smrtnost smanjivao se s dubinom, što podržava hipotezu da je temperatura mora ima ključnu ulogu u masovnoj smrtnosti. Istraživanja na populacijama za koje su podaci prije smrtnosti (gustoća i struktura veličine) potvrdili da je oporavak daleko od završetka tri godine nakon smrtnosti. Sveukupno, posljedica povišene temperature mora dovela je do gubitka od 70% biomase crvene gorgonije na istraživanim postajama. S obzirom na stopu rasta crvene gorgonije, za potpuni oporavak najugroženijih populacija bit će potrebno nekoliko desetljeća da se vrate na vrijednosti prije smrtnosti, ukoliko je to moguće. U kontekstu globalnih promjena, te uzimajući u obzir korelaciju s temperaturom, može se očekivati da će se učestalost ovakvih negativnih događaja povećati u sljedećim desetljećima. Mogu se očekivati dramatične posljedice za očuvanje ove vrste što bi bilo posebno loše za biološku raznolikost Sredozemnog mora.
