Proceedings of the collaborative research and training on genetic improvement of carp species in Asia
Type: Conference Proceedings
With financial support from Asian Development Bank, a carp genetic research project initiative was set up in 1995 assist the six major carp producing countries (Bangladesh, People's Republic of China, India, Indonesia, ...
Photographic image analysis for morphometric studies of tilapia
Type: Journal Article
Biologists have long employed morphometry as a tool in identification, grouping of populations and stock identification of fish. For tilapias, studies have been made on the variability of morphomeric characters in Egyptian ...
Genetic diversity of Nile tilapia (Oreochromis niloticus) throughout West Africa
Type: Journal Article
Nile tilapia (Oreochromis niloticus) is a globally significant aquaculture species rapidly gaining status as a farmed commodity. In West Africa, wild Nile tilapia genetic resources are abundant yet knowledge of fine-scale ...
Phenotypic and genetic parameters for body measurements, reproductive traits and gut length of Nile tilapia (Oreochromis niloticus) selected for growth in low-input earthen ponds
Type: Journal Article
In this study we present estimates of phenotypic and genetic parameters for body size measurements, reproductive traits, and gut length for Nile tilapia (Oreochromis niloticus) selected for growth in fertilized earthen ...
Closing the yield gap: improving production efficiency in smallholder farms of Nile tilapia through selective breeding
Type: Thesis
The aim of this thesis was to optimise the breeding program of Nile tilapia for a smallholder production system, thereby contributing to closing the yield gap. From Chapter 2 to 4, we generated information that can be used ...
Genetic evaluation of a complete diallel cross involving three populations of freshwater prawn (Macrobrachium rosenbergii) from different geographical regions of India
Type: Journal Article
Estimates of additive genetic, reciprocal and average heterosis effects were obtained from a three by three complete diallelcross experiment for giant freshwater prawn Macrobrachium rosenbergii. The data were generated in ...
Electrophoretic evidence for extensive hybrid gene introgression into commercial Oreochromis niloticus (L.) stocks in the Philippines
Type: Journal Article
The usefulness of isozyme and protein markers in identifying tilapia species and their hybrids is demonstrated Genetic characterization of Oreochromis niloticus populations from commercial farms, experimental stations, and ...
Genetic improvement and conservation of carp species in Bangladesh
Type: Report
This book contains six chapters 1)Introduction 2) Status of carp genetic resources 3)Brood stock management and artificial breeding of carp species in hatcheries 4)A breeding plan for cultured minor carp species 5)A breeding ...
Characterization of Ghanaian tilapia genetic resources for use in fisheries and aquaculture
Type: Conference Proceedings
Summary proceedings of a four-day workshop held on 4-7 June 1996, Accra, Ghana. Includes presentations, discussions and recommendations on developing techniques for characterizing tilapia genetic resources and utilizing ...
Maximum likelihood parentage assignment using quantitative genotypes
Type: Journal Article
The cost of parentage assignment precludes its application in many selective breeding programs and molecular ecology studies, and/or limits the circumstances or number of individuals to which it is applied. Pooling samples ...
