Genetic quality of cultured tilapia stocks in Africa
Type: Journal Article
African aquaculture is poised for rapid expansion. However, one of the key constraints holding back growth of the sector is the poor quality of the fish stocks available for culture. The problems of declines in growth ...
A computer software package for assessing and managing risks posed by experiments with genetically modified fish and shellfish
Type: Journal Article
Assessment and management of risk is needed for sustainable use of genetically modified aquatic organisms (aquatic GMOs). A computer software package for safely conducting research with genetically modified fish and shellfish ...
Fine-scale population structure and ecotypes of anadromous Hilsa shad (Tenualosa ilisha) across complex aquatic ecosystems revealed by NextRAD genotyping
Type: Journal Article
The anadromous Hilsa shad (Tenualosa ilisha) live in the Bay of Bengal and migrate to the estuaries and freshwater rivers for spawning and nursing of the juveniles. This has led to two pertinent questions: (i) do all Hilsa ...
Performance and nature of genetically improved carp strains in Asian countries
Type: Journal Article
The WorldFish Center and its research partners have recently made efforts to develop genetically improved carp strains. This paper analyses the comparative performance of the genetically improved carp strains on both average ...
Marine fisheries, genetic effects and biodiversity
Type: Journal Article
Preservation of marine biodiversity deserves serious consideration as almost 65% of the earth's organisms (excluding insects) are marine. There is little knowledge at present on the status of marine biodiversity. However, ...
Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
Inbreeding and effective population size in a coho salmon (Oncorhynchus kisutch) breeding nucleus in Chile
Type: Journal Article
A commercial breeding nucleus of coho salmon (Oncorhynchus kisutch) was established in Chile in 1997. This nucleus consists of two independent populations corresponding to different year-classes (even and odd, depending ...
Population structure and genetic variability of six bar wrasse (Thallasoma hardwick) in Northern South China revealed by mitochondrial control region sequences
Type: Journal Article
The genetic relationships among northern South China Sea populations of the six bar wrasse (<i>Thallasoma hardwicki</i>) were investigated. Fish collected from the Solomon Islands were used for geographic comparison. In ...
The impact of genetically improved farmed Nile tilapia in Asia
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM) and its research partners have recently developed a genetically improved Nile tilapia strain. This paper analyzes the potential impact of culturing ...
Response of two generations of selection to increased body weight in channel catfish, Ictalurus punctatus, compared to hybridization with blue catfish, I. furcatus, Males
Type: Journal Article
Two generations of selection for increased body weight in Kansas (AU-KS-2) and Marion (AU-MS-2) lines of channel catfish, Ictalurus punctatus, resulted in a 12% and 11% increase in body weight at market size, respectively. ...
