Breeding & genetics

Samantha L White et al, Fisheries and Oceans Canada, examined levels of mRNA in domesticated, wild and hybrid rainbow trout (Oncorhynchus mykiss) to investigate the influence of genotype (domesticated vs. wild, and their interactions in hybrids) and developmen…

In recent years, with the development of next-generation sequencing technology, a growing number of genes have been reported as being horizontally transferred from prokaryotes to eukaryotes, most of them involving arthropods. As a member of the phylum Arthropo…

Sea bream and sea bass aquaculture is already widely established in the Mediterranean basin, mainly reared in coastal net-pen facilities. The rapid increase of farming activity has also lead to an increase of escape incidents in Mediterranean farms, said Arech…

Pikeperch is one of the very important candidates for intensive freshwater aquaculture diversification. One of the biggest obstacle in the aquaculture of this species is the controlled reproduction, which is one of the most important part of the production cyc…

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…

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.

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…

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 …
