The effects of the polyunsaturated fatty acids (PUFAs), arachidonic acid (AA), eicosapentaenoic (EPA), docosahexaenoic (DHA), and prostaglandins (PGs) on oocyte maturation were investigated in a marine teleost, sea bass (Dicentrarchus labrax). Follicle-enclosed postvitellogenic, preovulatory oocytes cultured vitro was verified by assessing volume increase, lipid droplet coalescence, yolk clarification, germinal vesicle migration breakdown. Human chorionic gonadotropin administered as...
During their 3–4 first years of life, triploid sea bass Dicentrarchus labrax grew in a similar fashion to diploids fork length but more slowly than ( P <0·05) body weight, even when the reached full sexual maturity. However, from 48–53 months age triploids exhibited non‐significantly higher instantaneous growth rates, and thus fish were 4 or older, differences weight with no longer apparent, suggesting that triploidy could be benefit culture large (>1 kg) bass. The condition factor was...
Under constant short photoperiod, the spawning time of 2‐year‐old sea bass Dicentrarchus labrax was advanced as compared to controls, whereas spawnings were delayed under long photoperiod. High plasma levels 17β‐oestradiol (E 2/ ) and testosterone (T) in females coincident with appearance vitellogenic oocytes ovary, while high 11‐ketotestosterone (11‐KT) T males presence spermiating males. Although E 2 11‐KT low during remainder cycle, always >1 ng ml −1 both sexes, suggesting that could...
Adult two-year-old broodstock sea bass (Dicentrarchus labrax), raised in captivity, were fed ad libitum a natural diet (trash fish) until the end of their first spawning, and maintained under conditions light temperature. Six months before second fish randomly separated two tanks with running water (salinity 37.80‰, pH 8.3) similar environmental conditions. Fish different ration levels: group F, 1.04%, H, 0.45% body weight/day. The Jow supplied affected growth as indicated by decreased rates...
Spermiating male European sea bass Dicentrarchus labrax were treated with gonadotropin‐releasing hormone agonists (GnRHa), either a GnRHa injection (IN; 25 μg kg −1 body mass) or one of three types controlled‐release GnRHa‐delivery systems: fast release implants (EVAc; 1OO ), slow (EVSL; lOO ) and microspheres (MC; 50 ). Luteinizing (LH) was highly stimulated by all treatments, elevated plasma levels lasting for 2 days in injected fish (IN) 2, 4 6 weeks controlled‐release‐treated (EVAc, MC...
Visual species identification of cetacean strandings is difficult, especially when dead specimens are degraded and/or morphologically similar. The two recognised pilot whale (Globicephala melas and Globicephala macrorhynchus) sympatric in the North Atlantic Ocean. These very similar external appearance their morphometric characteristics partially overlap; thus visual not always reliable. Genetic ensures correct specimens. Here we have employed one mitochondrial (D-Loop region) eight nuclear...

European sea bass (Dicentrarchus labrax L.) is a species with group-synchronous ovarian development. A mechanism required which enables maturation to occur in the first clutches of oocytes without inducing subsequent clutches. The present study examined individual plasma variations testosterone (T), 17,20?-dihydroxy-4-pregnen-3-one (17,20?P) and 17,20?,21-trihydroxy-4-pregnen-3-one (20?S) both sexes, estradiol (E2) vitellogenin (VTG) females (n=15) 11-ketotestosterone (11KT) males (n=21), an...
