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.
Factors affecting early growth of Nile tilapia fry in hapa-in-pond environments
Type: Report
Hapas, usually suspended in fertilized ponds, have long been used for tilapia fry production (Santiago et al., 1985; Bhujel, 1997) and recently for fry rearing. In fish breeding programs, members of a full-sib family usually ...
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 ...
Decentralised Nile tilapia seed production
Type: Book Chapter
Local production of mixed sex Nile tilapia in irrigated rice fields has been introduced, established and then spread through farmer-to farmer contact in Northwest Bangladesh benefiting poor households in a number of ways. ...
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
Type: Book Chapter
Mass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ...
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) ...
