After a decade of research, Korea has produced individual glass eels for Japanese eel aquaculture. Although Japan also has this technology, its production of seed is not enough to meet external demand. To aid further development, a series of studies led by Dr …

A study led by Dong-Fang Deng, Oceanic Institute, Hawaii, USA has investigated the effects of storage temperature and duration on the quality of finished fishmeal fed to juvenile shrimp. Results found that although the fishmeals stored at 30 had less crude pro…

Ruth Francis-Floyd, University of Florida IFAS extension looks at successful fish health management. The document provides and introduction to disease, the types of fish diseases and what to do if fish are sick.

Previous studies have shown that higher sea temperatures tend to reduce both appetite and growth rates in farmed salmon. A recent NIFES study has demonstrated that salmon grow better at lower temperatures than was previously believed.

FSH and LH are two important hormones which regulate the processes of puberty and maturation. These hormones are secreted by the pituitary gland and are transported in the blood to the genitalia, where they regulate maturation.

The use of alternative lipids in tilapia feeds is becoming increasingly commonplace due to the rising cost of fish oil (FO). However, since this practice will reduce the content of heath beneficial long chain polyunsaturated fatty acids (LC-PUFA) in tilapia fi…

With aquaculture providing half of seafood eaten and the industry continuing to grow, research done by Emiko Phillips and Lyn Newton, University of West of England Bristol, found that the majority of consumers in the UK know little about aquaculture. The artic…

Gentle and short-lived crowding and pumping from the sea cage to the processing vessel is best in order to achieve good quality and long shelf life of salmon fillet. This is one of the conclusions of a project carried out at Marine Harvest from 2010-2011 invol…

A fundamental challenge in evolutionary biology is the mechanistic integration from genomic variation to fitness of organisms in their natural environment. Using RNA-sequencing, researchers led by Joanna L Kelley, Department of Genetics, Stanford University, C…

During earlier trials involving wild cod in captivity, scientists at Nofima have experienced problems getting the cod to eat pellet feed. Nofima, in collaboration with the Institute of Marine Research and SINTEF Fisheries and Aquaculture, has now demonstrated …

Researchers from the USDA/ARS National Center for Cool and Cold Water Aquaculture, Leetown, USA have conducted genome scans of rainbow trout families from a single broodstock population to identify the effect quantitative trait loci (QTL) have on stress respon…

A new study, by Villasante S, Morato T, Rodriguez Gonzalez D, et al, reports that fishing depths in the EU have increased, with more deep-sea fish species being harvested. Deep-sea fish populations are often more vulnerable to effects of fishing, and the ecolo…

The overall objective of the Commission's proposals for a modern and simpler Common Fisheries Policy (CFP) is to make fishing sustainable - environmentally, economically and socially. The new policy will bring fish stocks back to sustainable levels by ending o…

This factsheet published by the Southern Regional Aquaculture Center (SRAC) gives information on phytoplankton culture for aquaculture feed.

The potential impact of sea lice infestation on outwardly migrating Atlantic salmon smolts has been investigated, by researchers from the Marine Institute, Ireland, by treating populations of ranched salmon, prior to release, with a prophylactic sea lice treat…

Biologists from the University of Bonn have discovered that the cichlid fish Pelvicachromis taeniatus can see in the near infrared range; this was thought to be unlikely until now. Seeing in the infrared range is apparently helping fish to hunt in shallow Afri…

Recent advances in next-generation sequencing enabled an array of whole genome sequencing or re-sequencing projects in both model and non-model species. Such efforts have produced a wealth of genome resources. However, thorough genome analysis thereafter is es…

Catfish farmers in Vietnams Mekong River Delta are barely scraping by. They operate on the tightest of profit margins 3% to 5% in a good year and deal with a highly volatile, boom-and-bust export market. For an industry thats already on the brink, could the ad…

Fishmeal is a complex protein source that is commonly used in fish feed. A new article published in Animal Feed Science and Technology shows how fishmeal physical and chemical properties influence both the production of fish feed and the physical feed quality.…
