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...

Fishborne trematode (FBT) metacercariae were investigated in yellowfin goby, Acanthogobius flavimanus, collected from Shinan-gun and Muan-gun, Jeollanam-do (province), Korea. All collected fishes were examined using the artificial digestion method. In all of 15 gobies from Aphae-myeon in Shinan-gun, metacercariae of Stictodora spp. (334 metacercariae/fish), Heterophyes nocens (153/fish), and He...

In this study, we have analysed the expression of gonadotrophin-releasing hormone (GnRH) binding sites in somatic tissues (intestine, liver, gill, skeletal muscle, ovary, heart, stomach, kidney and spleen) of the gilthead seabream, Sparus aurata using 3-[125I]iodototyrosyl5-mammalian GnRH and auto-radiographic techniques. The qualitative and quantitative analysis showed the existence of a basal...

Fish is highly susceptible to deterioration without any preservative or processing measures and requires proper handling preservation increase its shelf life. Smoked fish traditionally processed by through an open process of hot smoked. in Indonesia, especially Papua, still carried out with capital small business scale so that the use tools simple. The aim this research was study proximate comp...

This study was carried out to investigate the effects of increasing levels propolis addition as a feed additive in seabream (Sparus aurata) diets on hematological parameters and fish fatty acids profile. Seabream with an average weight 12.04 ± 0.01 g were fed 0 (control), by 1.25, 2.5, 5, 10, 20 g/kg (abbreviated P1.25; P2.5; P5; P10 P20 respectively) supplemented for 10 weeks. The experiment c...

The effects of the dietary administration of two heat-inactivated whole bacteria from the Vibrionaceae family, singly or combined, on innate immune response of the seabream were studied. The two bacteria (Pdp11 and 51M6), which were obtained from the skin of gilthead seabream, showed in vitro characteristics that suggested they could be considered as potential fish probiotics. The fish were fed...
