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. ...
Response to bi-directional selection for frequency of early maturing females in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The present study was carried out to investigate a simple method for recording the occurrence of early maturing females in Nile tilapia at a fixed time after stocking and to estimate the response to bi-directional selection ...
A simple and inexpensive fish tagging method
Type: Journal Article
In many developing countries, availability of suitable tags for use in genetics and aquaculture research has been a problem as they are often expensive and have to be imported from other countries. A simple and inexpensive ...
Towards policies for conservation and sustainable use of aquatic genetic resources
Type: Conference Proceedings
Genetic stock identification is increasingly needed for fisheries management. Genetic technologies are being developed to increase food production from aquaculture and to document and evaluate aquatic species, subspecies ...
Seinability of four strains of Nile tilapia, Oreochromis niloticus, in Chinese ponds
Type: Journal Article
The objective of the current experiment was to examine seinability of four strains of Nile tilapia, O. niloticus, GIFT and Egypt 92, Egypt 88 and Sudan 78. The latter two are normally utilized in China.
Genetic variation in lytic activities of blood serum from Nile tilapia and genetic associations with survival and body weight
Type: Journal Article
The objective of the present investigation was to determine the genetic variation in lysozyme activity and SH activity in blood serum from a family material of Nile tilapia (O. niloticus) and to study the genetic associations ...
