Tilapia by-product hydrolysate powder in diets for Nile tilapia larvae
Acta Scientiarum: Animal Sciences, 2017 RESUMO. Objetivou-se avaliar a digestibilidade do hidrolisado proteico seco do resíduo da filetagem de tilápias (HPST) e sua inclusão em dietas para larvas de tilápia do Nilo. Para determinar os coeficientes de digestibilidade aparente, duas dietas foram elaboradas, referência e teste (com 20% do HPST) e para avaliação da inclusão, seis dietas foram ...

Integrative Zoology, EarlyView.We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Integrative Zoology, EarlyView.Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Formaldehyde Residue in the Muscle of Nile Tilapia
Asian Fisheries Science, 1995 Formaldehyde residues in muscle tissue were determined for Nile tilapia Tilapia niloticus which had been treated indefinitely with formalin at rates of 25 mg·I·1, and bath treatments of 125mg·l·1 for 1.5 h or 250 mg-1-1 for 1 h. In the indefinite treatment, formaldehyde in treated fish increased slightly from 48 to 72 h, and levels were back to normal

Changes in the structure of the phytoplankton community in a Nile tilapia fishpond [PDF]
Acta Limnologica Brasiliensia, 2018 Abstract Aim Our objectives were to recognize species that can serve as biological descriptors and evaluate the changes in the phytoplankton community throughout the grow-out period of the Nile tilapia (Oreochromis niloticus Linnaeus 1758) related to management practices and to limnological variables.

Journal of Fish Biology, EarlyView.Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Improving winter production of Nile tilapia: What can be done?
Aquaculture Reports, 2020 Despite being a tropical species, Nile tilapia is farmed in many subtropical regions worldwide, including southern Brazil, China, and Egypt, where production is hindered during the colder months of the year.
