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.
Development of aquatic animal genetic improvement and dissemination programs : current status and action plans
Type: Report
WorldFish Center in collaboration with the China Academy of Fishery Sciences organized the international “Workshop on Dissemination of Improved Fish Strains: Country-Specific Action Plans” on 21-22 September (2005) in ...
Importance and implementation of simple and advance selective breeding programs for aquaculture species in developing countries
Type: Conference Paper
Aquaculture is predicted to play a major and ever increasing role in meeting human needs for protein. In terrestrial animal and plant species genetic improvement programs have made a substantial contribution to productivity ...
Policies on release of improved fish strains in China
Type: Conference Paper
Since 1991, the certification, release and maintenance of new species for aquaculture have become part of the national policy in China. During the past 15 years, this policy has been conducted and improved and has begun ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
Mass selection for increased body weight at harvest over five generations in silver barb, Puntius gonionotus
Type: Conference Paper
Silver barb (Puntius gonionotus Bleeker 1850) is an Asian carp that is popular as a food fish. It is distributed throughout Thailand in rivers, canals, reservoirs and swamps. It is also cultured in ponds and paddy fields. ...
Selection for growth of Nile tilapia (Oreochromis niloticus L.) in low-input environments
Type: Thesis
This thesis is a part of Wageningen University’s Interdisciplinary Research and Education Fund project entitled “Optimization of nutrient dynamics and fish for integrated agriculture- aquaculture systems” (INREF-POND). The ...
Genetic improvement and effective dissemination: keys to prosperous and sustainable aquaculture industries
Type: Book Chapter
There is an increasing demand for fish in the world due to a growing population, better economic situation in some sectors, and greater awareness of health issues in relation to food. Since capture fisheries have stagnated, ...
Genetic parameter and genotype by environment interaction for body weight of Oreochromis shiranus
Type: Journal Article
Genetic and phenotypic parameter estimates for tagging and harvest body weights were obtained from the F1 base (377 offspring of 59 full-sib families), F2 (1241 offspring of 52 full- and 33 half-sib families) and F3 (1052 ...
