This study aimed to document the seasonal cycle of steroid levels in the plasma and ovary, including testosterone (T), estradiol-17&beta, (E2) and 17&alpha, 20&beta, dihydroxy-4-pregnen-3-one (DHP) in relation to ovarian development in wild populations of female blue tang fish. The gonadosomatic index (GSI%) maintained high values from April to July and increased from the II to IV ovarian stages and dropped in the V stage. Levels of plasma, ovary T and E2 and DHP were high from March to July. Plasma T and E2 levels were low in the II stage when most oocytes were previtellogenic, reaching a peak during spawning, and decreased in the V stages when fish were going to late spawning and termination. DHP was detected in all stages of the ovary with a higher level in spawning fish but decreased after spawning. These results revealed that T, E2 and DHP could be involved in ovarian development and DHP may play a significant role as a maturational inducing hormone in blue tang fish.

In the present study, the relationships between sagittal otoliths (otolith length (OL), height (OH) and weight (OW)), fish size (fish length (TL) and weight (W)) in brown comber (Serranus hepatus, Linnaeus, 1758) were analysed. Fish specimens (N=504, 41–133 mm in TL and 1.05–31.98 g) were captured by bottom trawl vessels from off the Güllük Bay (Southern Aegean Sea) between January and December 2013. Left otolith pairs were used for calculations since there was no statistical differences between left and right otoliths (P>0.05). Regression formulas were used as follows: TL= 16.94*OL+10.14, TL= 26.77*OH+24.88, TL= 375.7*OW0.315, W= 0.251*OL2.431, W= 2.009*OH1.917, W= 854.0*OW+1.552, OH= 0.600*OL–0.394, OW= 0.00025*OL2.555 and OW= 0.001*OH2.007. Calculated regressions were revealed a high coefficient of determinations ranging from 0.865 to 0.960. It is found that otolith sizes and weight are good indicators of the total length and weight of S. hepatus.

Spatial management of discards has attracted increasing interest as a potential mitigation measure. However, most studies are restricted to commercial species. The aim of the present work was to fill this gap by identifying and mapping the spatial distribution of five non-commercial species with high frequency of occurrence in the discarded catch of bottom trawl fishery in the Aegean Sea, i.e., Brown comber Serranus hepatus, Mediterranean scaldfish Arnoglossus laterna, Red bandfish Cepola macrophthalma, Argentine Argentina sphyraena, and Boarfish Capros aper. For this purpose, Generalized Additive Models were used to account for catch dependency on environmental parameters in order to explore the spatial distribution of species. Modeling results revealed that the spatial distribution of species was driven by environmental variables. Depth was the most informative variable explaining most catch variation in all species. For A. laterna, C. macrophthalma, and S. hepatus the highest estimated values of catch were located over the continental shelf and at shallower waters inside gulfs, whereas C. aper and A. sphyraena catch were more broadly distributed across the study area and at greater depths. Seasonal variations in species catch were also observed, probably related in most cases to species reproduction period. Mapping species distribution is essential for the identification of priority areas of protection in future marine spatial plans.

The Pacific blue tang, Paracanthurus hepatus, is consistently among the top 20 marine ornamental species imported into the USA, with all specimens presently sourced from wild stocks. Captive culture of this species through metamorphosis has not been previously documented and fundamental information regarding reproduction, larval culture, and production techniques is scarce. This study aimed to elucidate methods that would advance our understanding and success with captive propagation of this species. A total of 50,000 eggs were collected from a single broodstock population and stocked in a 1000-L tank. Beginning at 3 d posthatch (DPH), larvae were fed three times daily a diet comprised exclusively of copepod nauplii. At 12 DPH, enriched rotifers were first fed followed by powdered feed (20 DPH) and first instar Artemia (21 DPH). Large mortality events were observed at 7 and 20 DPH, corresponding with starvation and flexion, respectively. By 41 DPH, the majority of the remaining larvae began associating with the bottom of the culture tank. On Day 50, the first signs of blue pigmentation marked the beginning of metamorphosis. A total of 27 juvenile blue tangs were cultured during this trial. This effort represents the first successful culture of this species in captivity.

This study describes the length-weight relationship (LWR) for Serranus hepatus from Iskenderun Bay, Northeastern Mediterranean, Turkey. A total of 202 individuals were caught from Iskenderun Bay, during the 2015-2016 fishing season. The total length ranged from 5.7-9.5 cm and body weight 2.23-12.19 g. Length-weight relationship was found as the W = 0.0172L2.9664 (R2=0.84, F1,200=21.221, P < 0.001) and SEb= 0.091 (t-test: 32.706 p < 0.01). The types of growth were found isometric growth for all indivuduals of S. hepatus.

El acceso a datos actualizados, sobre los nombres y distribución de las especies de crustáceos presentes en un área en particular, es un primer paso para evaluar cambios debidos a factores locales, regionales o globales, como la sobrepesca, la contaminación y el cambio climático. Los datos en este estudio están basados en las expediciones de los buques de investigación Skimmer (20 estaciones, 1978-1980) y Victor Hensen (1992-1994, 12 estaciones) en el estuario del Golfo de Nicoya. Los crustáceos fueron recolectados mediante redes de arrastre tipo Otter (Skimmer, malla 3.5 cm) y por tipos Otter y Beam (V. Hensen, mallas de 2.5 cm y 1.9 cm) a profundidades entre 10 y 228 m. Datos en dos estudios posteriores aportaron información para una zona de entre-mareas en la región superior del Golfo y para estaciones en la boca del estuario, lo que incrementa el ámbito de profundidad de 0 a 350 m. Se revisaron las publicaciones originales y se hicieron 32 actualizaciones de los nombres de las especies con base en la literatura reciente y en la página de red World Register of Marine Species (WORMS). El total de especies para ambas expediciones fue de 131, del que 119 fueron decápodos y 12 fueron estomatópodos. Los datos en los otros dos estudios, así como la revisión de las colecciones en el Museo de Zoología de la Universidad de Costa Rica, incrementó en 43 el número de registros, para un total de 174 especies en los sedimentos del estuario. Para el Skimmer el número mínimo de especies en una estación fue de cuatro (tres estaciones) y el máximo de 27, con un promedio de 12.3 especies / estación. Para el V. Hensen el mínimo de especies en una estación fue de ocho, con un máximo de 27 y un promedio de 17 especies / estación. Las especies presentes en 50 % o más de las 20 estaciones de la expedición del Skimmer, fueron: Callinectes arcuatus, Rimapenaeus faoea, Penaeus brevirostris, Achelous asper y Hepatus kossmanni. Para la expedición del V. Hensen las especies presentes en más del 50 % de las 12 estaciones, fueron: A. asper, Sicyonia disdorsalis, S. picta y Persephona subovata. Durante el estudio del Skimmer, un total de 15 especies fueron encontradas en solo una estación, mientras que para el V. Hensen el número fue de 26. Se digitalizaron dos matrices de datos de presencia-ausencia de las especies en las estaciones y con base en los nombres actualizados de las especies recolectadas por el Skimmer (57 especies x 20 estaciones) y V. Hensen (82 especies x 12 estaciones) se les aplicó un Análisis No Métrico Dimensional de Escala (NMDS) para obtener una distribución de las estaciones en un espacio bi-dimensional. Los resultados revelaron unos grupos heterogéneos de estaciones. Algunos sub-grupos de tres o cuatro estaciones concuerdan con su proximidad geográfica. Las cuatro estaciones del V. Hensen en la boca del estuario a profundidades mayores a los 100 m fueron separadas más claramente de las otras, y podrían indicar una transición, desde aguas estuarinas hacia aguas profundas, en la composición de la fauna de crustáceos. Evaluaciones futuras de la diversidad de crustáceos del Golfo de Nicoya deben de considerar la amplia distribución espacial de algunas especies y la restringida de otras. La variabilidad temporal es también importante en el estuario, tal como lo evidenció la oscilación de la población de Pinnixulala valerii en un periodo de tres años.

A single individual of the palette surgeonfish, Paracanthurus hepatus, is reported for Bat Yam, Israel. This is the first report of this species for the Mediterranean Sea. Since this Indo-Pacific species does not occur in the Red Sea, and is one of the most popular marine aquarium fish, its introduction is referred to as aquarium release. The impact of aquarium trade on biological invasions in the Mediterranean Sea is briefly revised and discussed.

We report several new crab specimens, representing new taxa and new occurrences from the Miocene of Veracruz and Chiapas, SE Mexico. Most of the specimens were collected by the late Emily H. Vokes, in 1963 from outcrops of the Agueguexquite Formation, Veracruz, Mexico. The age range of the studied material support an upper Miocene age for the Agueguexquite Formation, as previously suggested. Ranina sp. and Portunus sp. cf. P. atecuicitlus Vega et al.1999 from the middle Miocene, Tuxpan Formation, are also reported. We also illustrate an incomplete portunoid specimen from the lower Miocene Tulija Formation of Chiapas, similar to Necronectes A. Milne Edwards, 1881. The presence of Hepatus Latreille, 1802, Persephona Leach, 1817, and Euphylax Stimpson, 1862a, in the Agueguexquite Formation represent the first record of these genera in the fossil record of Mexico. The occurrence of Eupilumnus? vokesae Luque, sp. nov. would represent the first fossil record of the genus known to date, extending its stratigraphic record into the Miocene. Eurytium granulosus Schweitzer, Velez-Juarbe, Martinez, Collmar-Hull, Feldmann and Santos, 2008, first reported from the Miocene of Puerto Rico is also identified among the specimens here studied.

New records of Brachyura crustaceans and range extension of some species from the Colombian Caribbean Sea. Three species of Brachyura crabs, Tyche emarginata White, 1847; Piloslambrus g uerini (Brito Capello, 1871), and Hepatus scaber Holthuis, 1959, are recorded for first time in Colombian Caribbean Sea. Also, the distribution range of 20 previously recorded species is widened towards the north of the country. Samples were collected during INVEMAR-CORPOGUAJIRA cruise between March and April 2005 at the continental shelf (10 and 50 m depth) in La Guajira.

In this study, the complete mitogenome sequence of the palette surgeonfish, Paracanthurus hepatus (Perciformes: Acanthuridae), has been sequenced by next-generation sequencing method. The assembled mitogenome was 16 498 bp in length, consisted of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes. The overall base composition of palette surgeonfish was 28.6% for A, 28.6% for C, 16.3% for G, 26.4% for T and showed 87% identities to somber surgeonfish Zebrasoma flavescens. The complete mitogenome of the palette surgeonfish provides essential and important DNA molecular data for further phylogeography and evolutionary analysis for surgeonfish's phylogeny.
