Abstract. Ukenye EA, Megbowon I. 2023. Comparison of genetic diversity farmed Oreochromis niloticus and wild unidentified tilapia (Wesafu) using microsatellite markers. Biodiversitas 24: 2953-2957. Nile (Oreochromis Linnaeus, 1758) are cichlid species important nutritional economic value with good aquaculture potential. Assessing comparing the these will assist in information development for co...

Abstract This paper discussed domestication strategies of Tinfoil barb from different populations for evaluation potential fish candidate freshwater aquaculture development. Collection and maintenance wild-caught adult was the first step in followed by characterization fish, broodstocks selection maturation, control reproduction, larval rearing. The presented an excellent performance to adapt n...

Abstract Appropriate fertilization practices play a crucial role in the maintenance of genetic diversity within captive fish broodstocks. We assessed influence vitro storage gametes (0-, 7- and 14-days post-stripping) at 1 °C on ovarian fluid pH, sperm motility, embryo viability critically endangered Finnish landlocked salmon ( Salmo salar m. sebago ) population. A repeated full-factorial desig...

Preserving and maximizing genetic diversity in conservation programs, including for restocking, are of high importance. The threatened European flat oyster ( Ostrea edulis ) is currently the subject several applied restocking but concerns have been raised over potential negative side effects these example due to our limited knowledge about natural populations releasing offspring hatchery origin...

In the aquaculture industry, fish oil is widely used as a nutritional supplement to promote gonadal maturation of broodstocks, while mechanism on ovary development remain unclear. Herein, female adult spotted scat ( Scatophagus argus ) with most ovaries at phase II were fed diets containing 8% soybean (SO) or (FO) for 60 days. The final average body weight was similar between FO and SO groups. ...

Quahog Parasite Unknown (QPX) is a protistan parasite affecting hard clams Mercenaria mercenaria along the Northeastern coast of the United States. The geographic distribution and occurrence of disease epizootics suggests a primary role of temperature in disease development. This study was designed to investigate the effect of temperature on constitutive and QPX-induced defense factors in M. me...

Testis maturation, germ cell development and function of sperm, are related to lipid composition. Phosphatidylcholines (PCs) play a key role in the structure and function of testes. As well, increases of polyunsaturated fatty acids (PUFA) and highly unsaturated fatty acids (HUFA), especially arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are essential for ma...
