Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus
Type: Journal Article
Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets ...
Survival, male morphotypes, female and male proportion, female reproductive status and tag loss in crosses among three populations of freshwater prawn Macrobrachium rosenbergii (de Man) in India
Type: Journal Article
The present study examined the variation in survival, proportion of male morphotypes, female and male proportion, female reproductive status and tag losses in nine crosses from a complete (3 × 3) diallel mating of three ...
Fish trait preferences: a review of existing knowledge and implications for breeding programmes
Type: Journal Article
Continued growth of the aquaculture sector will rely on the availability of fish with traits that respond to the needs and preferences of these users along the value chain. Such trait responsiveness requires that fish ...
Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
Type: Journal Article
The aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus).
Sibship assignment to the founders of a Bangladeshi Catla catla breeding population
Type: Journal Article
In terms of quantity produced, Catla catla is the sixth most important finfish aquaculture species produced globally in 2015. It is primarily grown in South Asia, often on a small scale in polyculture with other species. ...
Breeding for robustness: Investigating the genotype-by-environment interaction and micro-environmental sensitivity of Genetically Improved Farmed Tilapia (Oreochromis niloticus)
Type: Journal Article
The objectives of this study were (i) to quantify the degree of G x E by assessing the growth performance of Genetically Improved Farmed Tilapia (GIFT) across three countries (Malaysia, India and China) and (ii) to quantify ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Genetic evaluation of growth and survival at 6 weeks old fry of Egyptian Nile Tilapia (Oreochromis niloticus) between improved Abbassa and commercial Manzala strains in a diallel crossing
Type: Journal Article
The main objectives of this study were to evaluate growth performance and estimate line crossing parameters of improved Abbassa tilapia strain and a commerciall Manzala strain within a complete diallel cross at 6 weeks old ...
Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
Genotype by environment interaction and genetic heterogeneity of environmental variance of body weight at harvest in genetically improved farmed tilapia (Oreochromis niloticus) reared in 3 different countries
Type: Journal Article
Establishing breeding programs that improve farmed fish performance across multiple environments is crucial in a globalized aquaculture market. The main objectives of the current study were to assess the growth performance ...
