Aquaculture Reports, 2022 In the present study, two hatchery strains of Oreochromis niloticus and two of O. andersonii sourced from different hatcheries in Zambia were subjected to the same feeding and management regimes in a controlled indoor tank environment. All strains were stocked at a mean weight of 2.1 ± 0.01 g and harvested after 175 days.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species
Animal Research and One Health, EarlyView.A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Biological Diversity, EarlyView.This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

Food Safety and Health, EarlyView.ABSTRACT Currently, small‐molecular‐weight collagen peptides are a research hotspot in functional factor development due to their high bioavailability and diverse bioactivities. In this study, gelatin was extracted from tilapia (Oreochromis niloticus) scales by hot water extraction, followed by pepsin hydrolysis and ultrafiltration to obtain the < 3 ...

Oreochromis Oreochromis comprises approximately 20–40 species, depending on the generic concept. Most Oreochromis are found in East Africa, although two are native to West Asia. Some authors have recognised Alcolapia, Neotilapia, Nyassalapia, and Vallicola as valid genera.

Cold tolerance of selective breeding of Oreochromis niloticus and oreochromis aureus [PDF]
Egyptian Journal for Aquaculture, 2011 Selected fish for higher growth rate from both O. niloticus and O. aureus were collected and subjected to challenge test for cold. In addition to, fish of both species collected from production ponds of Abbassa were used to compare the cold tolerance of fish. Fry of similar age were grown under identical conditions. O.
