In this paper, we present a brief anatomical description of the torus longitudinalis and the valvula cerebelli in a percomorph fish, the gilthead seabream (Sparus aurata) based on the analysis of serial brain sections stained by paraldehyde fuchsin, Groat's hematoxylin-picroindigocarmin and cresyl violet. The existence of a small undescribed fiber tract directly bridging the ventral torus longi...

 Acanthopagrus latus is one of the major commercially exploited species in the Persian Gulf. In recent years, it has gained importance as a candidate for aquaculture. Haematological parameters of wild-caught specimens were studied during the pre-spawning period to determine if they are influenced by the sex of fish. Blood samples were collected from 55 Fish (30 female and 25 male) captured from...

The total lipid content and composition of fatty acids of the liver and muscles of wild and cultured male and female Acanthopagrus latus were determined by gas-liquid chromatography. There were quantitative differences between individual fatty acids in the tissues investigated depending on sex and location. In all the samples studied, sex and location considered, the principle saturated fatty a...

In this study, 50 000 European seabass and 50 000 gilthead seabream with an average wet weight of 1.6 g were cultivated during 600 days under low water salinity conditions (7‰) of which getting out from underground at fixed 19°C, being produced in earthen ponds under commercial production conditions. From the beginning to the end of the experiment, the same fish feeds were used for both species...

Using stomach contents from 203 spotted dolphins (Stenella attenuata) killed in the yellowfin tuna fishery, we modeled the weaning process of calves. Spotted dolphins began to take solid food at approximately 6 mo of age, or 115 cm, but continued to suckle until they were nearly 2 yr old. Calves tended to feed more frequently on squid as they got older, which suggested there was a shift in diet...

This study was performed to determine the optimum level of soybean meal diets for two banded sea bream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth...

Surveillance for mercury (Hg), lead (Pb) and cadmium (Cd) contamination in tuna products is crucial for consumer food safety. Hg, Pb and Cd contaminants were monitored in a total of 60 specimens of fresh little tunny (Euthynnus alletteratus) and popular brands of skipjack and yellowfin (Katsuwonus pelamis and Thunnus albacares) canned tuna commercially available in Tripoli, Libya. Direct Mercur...

Information on the distribution and habitat preferences of ecologically and commercially important species is essential for their management and protection. This is especially important as climate change, pollution, and overfishing change the structure and functioning of pelagic ecosystems. In this study, we used Bayesian hierarchical spatial-temporal models to map the Essential Fish Habitats o...
