This study aimed to develop a suitable feeding program for the Asian sea bass, lates calcarifer fingerlings under supersaline condition by testing different feeding rates (FR) and feeding frequencies (FF). Three feeding rates namely; 1%, 2% and 4% and three feeding frequencies 1X, 2X and 4X were used in the study. Results showed that growth after 60 days parameters gave the highest values with ...

During the last decades, aquaculture has been the world’s fastest growing food production technology. This is primarily due to the fact that control with the production process has allowed innovations thorough the supply chain, leading to increased demand and thereby increased production. We investigate this process for three leading species; salmon, sea bass and shrimp. The process has been ve...

Hypoxia is a pervasive problem in coastal environments and is predicted to have enduring impacts on aquatic ecosystems. Intraspecific variation in hypoxia tolerance is well documented in fish; however, the factors underlying this variation remain unknown. Here, we investigate the role of the heart in individual hypoxia tolerance of the European sea bass (Dicentrarchus labrax). We found individu...

—Microsatellite DNA variation was examined at 11 loci in five populations of Florida largemouth bass Micropterus salmoides floridanus (N 1⁄4 175) and eight populations of northern largemouth bass M. s. salmoides (N 1⁄4 249). Distinct allele frequencies with 33 private alleles between subspecies (threshold frequency, 0.05) and 19 private alleles among three geographic regions distinguished betwe...

In sea bass (males and non-vitcllogcnic females) estradiol (E2) treatment caused the appcarnnce in the bloodstream of a new protein that was identified as the vitellogenin (VTC) moleculc for this teleost spccies. The molecular weight of the sca bass VTG (445 kDa) and its amino acid composition was similar to that of other teleosts. VTC was purified by doublcstep chromatography and then used to ...

Lactic acid bacteria (LAB) collection was identified from enteric organs of healthy sea bass and sea bream cultured in tunisia. Thus we charecterized mainly Enterococci group with predominance of E. faecium (53%) and E. faecalis (21%). E. sanguinicola, E. casseliflavus, E. mundtii, E. gallinarum, E. pseudoavium, lactococcus lactis, Aerococcus viridans and Carnobacterium sp. were also identified...

The European sea bass, Dicentrarchus labrax, is a high market value marine and coastal species which feeds on small fish (TORTONESE, 1986). It inhabits coastal waters between 10 and 100 m in the Mediterranean, Black Sea and the European and African Atlantic coasts (North to Scandinavian waters and South to Morocco) (MOREIRA et al., 1992; LLORIS, 2002). It is an important species for the Mediter...

Early feeding (started during gut metamorphosis and establishment of the hypothalamic-pituitary-interrenal axis) with probiotic-supplemented diets, besides modifying the intestinal microflora, evoked profound effects on the physiology of fish larvae. Using rotifers and Artemia as living vectors, the autochthonous bacterium Lactobacillus delbrueckii delbrueckii or a multispecies probiotic formul...

Dielectric properties and sensory assesment of sea bass (Dicentrarchus labrax, L.) stored under six different conditions over a period of 75 hours were investigated. Declines of torrymeter values over time were established under all storage conditions, but showed variability. The correlations between torrymeter readings and Quality Index Method (QIM) results were studied. Significant negative c...

Sea-bass (Dicentrarchus labrax) grow under different salinity regimes, from the open sea to lagoons and even rivers, but some mortality has been recorded in juvenile stages when exposed to low salinity water. Changes in water permeability of different osmoregulatory tissues could be the cause of reduction in blood osmotic pressure and death in some fish in fresh water (FW). In order to explore ...
