Breeding & genetics

Southeast Asia's largest, yet long-troubled shrimp farming firm, PT Dipasena Citra Darmaja, has been given a much-needed boost as the Asset Management Company (PPA) managed to seal a US$240 million commitment to help finance the firm's revitalization.

Atlantic halibut (Hippoglossus hippoglossus) is a high-value, niche market species for cold-water marine aquaculture. In a University of Stirling study, Christos Palaiokostas et al discovered that all-female halibut production is commercially possible using in…

Cryopreservation is a process to maintain genetic material (such as spermatozoa) in subzero freezing. Abinawanto Zuraidah and Retno Lestari, University of Indonesia, disscussed the effect of skimmed milk on spermatozoa quality of silver barb (Barbonymus gonion…

Similarities in how different organisms look can indicate a close evolutionary relationship. Conversely, great differences in appearance can suggest a very distant relationship, as in many adult marine fish species. For the first time, however, a Smithsonian s…

This article provides a quick guide to breeding males for tilapia farming and best practice for hatchery, grow out and slaughter, writes Lucy Towers, editor of TheFishSite.

MicroRNAs (miRNAs) are an abundant class of endogenous small RNA molecules that downregulate gene expression at the posttranscriptional level. This study by Rune Andreassen, Oslo and Akershus University, et al, aims to identify and characterize miRNA genes in …

The ability of species and populations to adapt to environmental change is the cornerstone of the emerging field of ecological genomics. Until recently, genome-wide studies of genetic adaptation in non-model organisms were not possible. Steve Smith, Flinders U…

Aquaculture is the fastest growing food production system worldwide and is particularly important in bridging the gap between fish demand and supply in Nigeria. This study was carried out by F.O.A George et al, University of Agriculture, Nigeria, to determine …

Terrestrial livestock are so different that they often have nicknames, but thousands of farmed fish look so similar that many are surprised to learn that biologists claim that fish may have different personalities too. Scientists at Nofima have studied the ind…

Comparative genomics is a powerful tool to transfer genomic information from model species to related nonmodel species. Yu Zhang et al, Auburn University, chose catfish linkage group 8, which was found to contain microsatellite markers associated with the tole…

With little genetic information available on Catla carp, T.K.Mohapatra et, West Bengal University of Animal and Fishery Sciences, have carried out a study to evaluate the genetic variation and phylogenetic relationship among the two different stocks of Catla c…
