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 ...
Genetic diversity in wild stocks of the giant freshwater prawn (Macrobrachium rosenbergii): implications for aquaculture and conservation
Type: Journal Article
The giant freshwater prawn (Macrobrachium rosenbergii) is cultured widely around the world but little is known about the levels and patterns of genetic diversity in either wild or cultured stocks. Studies have suggested ...
Pipette and paper: Combining molecular and genealogical methods to assess a Nile tilapia (Oreochromis niloticus) breeding program
Type: Journal Article
The paper compared molecular and paper records of pedigrees in a Nile tilapia breeding program, the Abbassa line in Egypt. It established a novel pipeline of checks and balances based on molecular data to correct erroneous ...
Genetic diversity and selective breeding of red common carps in China
Type: Journal Article
China has a very rich genetic diversity in common carp (Cyprinus carpio) and the red common carp plays an important role in Chinese aquaculture and genetic studies. Selective breeding, particularly crossbreeding has been ...
Genetic improvement of the herbivorous blunt snout bream (Megalobrama amblycephala)
Type: Journal Article
Selection experiments with the herbivorous blunt snout bream or Wuchang bream (Megalobrama amblycephala) were started in 1985. Mass selection for size and length/depth ratio resulted in a significant increase in growth and ...
Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The main objective of this study was to quantify the heritable variation for growth rate of GIFT, and the contribution of IGEs to this heritable variation. Here we describe the experiment conducted for this purpose, and ...
High level of hybridisation in three species of Indian major carps
Type: Journal Article
Thirty individuals of each species of Indian major carps, i.e., Catla catla, Cirrhinus cirrhosus (C. mrigala) and Labeo rohita, obtained from a nursery near Mymensingh, Bangladesh were analysed by means of allozyme ...
Down to earth thoughts on conserving aquatic genetic diversity
Type: Journal Article
A discussion is presented on the topic of maintaining genetic diversity in aquatic ecosystems, considering the various threats caused by irreversible damage or loss to the environment. The current situation in aquaculture ...
Genetic considerations on acquisition and maintenance of reference populations of tilapia
Type: Journal Article
The maintenance of reference populations of Tilapia is discussed, examining genetic considerations to be taken into account to conserve the gene pool to prevent genetic drift and prevent detrimental levels of inbreeding. ...
Selective breeding in fish and conservation of genetic resources for aquaculture
Type: Journal Article
To satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main ...
