Comparison of African tilapia partial harvesting systems
Type: Journal Article
Three typical African partial harvesting systems and an unfished control were compared for gross yield. Fish grew undisturbed on an input regime based on that used by Malawian smallholding farmers for 122 days. Then, for ...
Genetic and environmental factors affecting growth of Nile tilapia (Oreochromis niloticus) juveniles: Modelling spatial correlations between hapas
Type: Journal Article
The aim of this study was to quantify the environmental and genetic effects on early growth of Nile tilapia, Oreochromis niloticus.
Reproductive and patho-physiological responses of blue tilapia (Oreochromis aureus) exposed to chromium with or without chelating substances
Type: Journal Article
Water pollution with chromium included significant negative impact in the hematological and biochemical parameters together with marked histopathological alteration and lowering reproductive performance of fish. The addition ...
Comparative growth of Egyptian tilapias in response to declining water temperature
Type: Journal Article
The current study was conducted to evaluate performance of Egyptian tilapia species and populations under a decreasing temperature regime to identify the components of growth.
Effect of dietary probiotic Biogen supplementation as a growth promoter on growth performance and feed utilization of Nile tilapia Oreochromis niloticus (L.)
Type: Journal Article
Probiotic microbial feed supplements are gaining wide acceptance in livestock production, and may be applicable to aquaculture production systems. The present study was conducted to examine probiotic treatment in the ...
Simulation of optimal harvesting strategies for small-scale mixed-sex tilapia (Oreochromis shiranus Boulenger 1896) ponds using a bio-economic model
Type: Journal Article
A cohort-based bio-economic biomass growth and economic model, validated with data from experiments conducted in Malawi, was used to identify an optimal harvesting strategy for mixed-sex tilapia ponds.Three harvesting ...
Growth performance and feed utilization of Nile tilapia Oreochromis niloticus (Linnaeus, 1758) and tilapia galilae Sarotherodon galilaeus (Linnaeus, 1758) fingerlings fed plant protein-based diets
Type: Journal Article
This study was designed to determine the effect of complete substitution of fish meal (FM) by three plant protein sources including extruded soybean meal (SBM), extruded full-fat soybean (FFSB) and corn gluten meal (CGM) ...
Efficiency of African catfish Clarias gariepinus in controlling unwanted reproduction of Nile tilapia Oreochromis niloticus in low input production system
Type: Journal Article
The present experiment was conducted in twelve earthen ponds 2100-m2 at WorldFish Center research facility at Abbassa, Egypt, to assess the efficiency of African catfish (Clarias gariepinus) in controlling unwanted Nile ...
Aquaculture in Jamaica
Type: Journal Article
Jamaica, with its overfish marine resources, has become a major tilapia producer in Latin America led by a small number of large farms practicing tilapia culture with considerable commercial success. Across the country, ...
Socioeconomics and production efficiency of tilapia hatchery operations in the Philippines
Type: Journal Article
With the recent availability of genetically improved Nile tilapia strain in the Philippines, it is important to look at the existing profile of tilapia hatchery operations in the country to help examine the potential ...
