Fluctuations in growth are heritable and a potential indicator of resilience in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Resilience can be defined as the capacity of an animal to be minimally affected by perturbations or to quickly recover to the state it had before the perturbation. When applied to production animals, resilience is defined ...
Inbreeding and effective population size in the Malaysian nucleus of the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A fully pedigreed population of the GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus) was established in Malaysia during 2001 and 2002. The selection program was focused on the ...
Genotype by environment interaction between aerated and non-aerated ponds and the impact of aeration on genetic parameters in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A major problem in smallholder Nile tilapia (Oreochromis niloticus) farms is that the achieved production is much lower than under optimal management. One of the main environmental factors contributing to lower production ...
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ...
Apparent digestibility coefficients of local palm kernel cakes, rice bran, maize bran and sago flour in the GIFT strain of tilapia (Oreochromis niloticus)
Type: Journal Article
An experiment was conducted to estimate the apparent digestibility coefficients (ADC) of macronutrients and energy of local palm kernel cakes, rice bran, maize bran and sago flour available in tilapia, Oreochromis niloticus ...
Cockle (Anadara granosa) seed produced in the laboratory, Malaysia
Type: Journal Article
An account is given of a development project for the production of cockle seed and subsequent transfer of thetechnology used to the fisherfolk of Kuala Juru for the setting up of hatcheries for bivalve seed production.
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 ...
Quantitative trait loci controlling swimming performance and their effect on growth in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Critical swimming speed (Ucrit) is an important measurement of swimming performance and a good indicator for cardio-respiratory health. It offers a new opportunity to select fish with better fitness. However, the genomic ...
Flesh characteristics: estimation of genetic parameters and correlated responses to selection for growth rate in the GIFT strain
Type: Journal Article
Genetically improved farmed tilapia (GIFT) has undergone ten generations of selection for harvest body weight in Malaysia, but there have been no reports on genetic parameters for flesh characteristics for this strain. In ...
Genetic parameters for resistance to Tilapia Lake Virus (TiLV) in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Tilapia Lake Virus (TiLV) is one of the primary disease concerns for tilapia farming, with mass mortality events and biosecurity restrictions threating aquaculture in several continents. Selective breeding for improved ...
