Commercial bottom trawling, the technique of pulling fishing gear across the seabed to catch fish and other seafood, releases pollutants trapped in the seabed, which can negatively affect local marine life and ecosystems. Recent findings from a Norwegian fjord…

The Status of key Australian fish stocks report, by the Australian Government, assesses the biological sustainability of the key wild caught fish stocks against a nationally agreed framework. In short, for the key fish stocks the report examines whether the ab…

Pharmaceutical drugs that end up in the world's waterways after being excreted, flushed and treated at wastewater treatment plants may lead to unexpected ecological impacts, according to a new study of wild European perch. Tomas Brodin and colleagues from Ume …

This factsheet published by the Southern Regional Aquaculture Center (SRAC) gives information on stress and its role in fish disease.

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 six-week feeding trial was conducted to investigate the suitability of animal oils as total replacement for cod liver oil (CO) in rainbow trout juvenile feeds. The effect of animal fats on the growth performance, survival and fatty acid profile was measured.…

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.

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…

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…

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…

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.

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…

This factsheet by the Southern Regional Aquaculture Center (SRAC) gives information on diseases of concern in molluscan aquaculture.

This factsheet by the Southern Regional Aquaculture Center (SRAC) gives information on amyloodinium ocellatum, an important parasite of cultured marine fish.

This factsheet by the Southern Regional Aquaculture Center (SRAC) gives information on disease prevention on fish farms.

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…

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…

Populations of large pelagic predators have declined recently due to intensified exploitation. Boris Worm and Derek P. Tittensor, Dalhousie University, Canada, look at the range contraction of large marine pelagic predators, specifically tuna and billfish, by …
