Aquaculture has the potential to make a significant contribution to the increasing demand for aquatic food in most world regions; however, in order to achieve this goal, the sector will have to face significant challenges, including the production intensificat…

A new Seafish report shows that the food chain should be the first choice for discarded fish that could be landed under a future discard ban, but when that is not practicable then utilisation for fishmeal or fish oil reduction for animal feed, is currently the…

Oxidants are used in aquaculture as disinfectants or to enhance water quality. Hydrogen peroxide and sodium carbonate peroxyhydrate can be sources of dissolved oxygen in emergency situations where mechanical aeration is not possible, writes Claude E. Boyd, Aub…

Among multigene families, ribosomal RNA (rRNA) genes are the most frequently studied and have been explored as cytogenetic markers to study the evolutionary history of karyotypes among animals and plants. By applying cytogenetic and genomic methods, Rafael T N…

Processing of shrimp Artemia cysts is an important factor in price determination. Alireza Asem, Iran, therefore looks at new concepts for hatching quality and evaluation of Artemia.

In commercialization and high stocking density of culture practice, feeding has a significant contribution for fast growth and high yields. Aquafeed has many ingredients in highly balanced nutritious components for enhancing the digestive mechanisms in fish an…

Some countries in Southeast Asia are embarking on anchored Fish Aggregating Device (FAD) programmes to boost fish production and to increase food security. This advisory note from the FAO was written to provide guidance to fisheries managers and fishers on the…

Just when traceability scares have retailers across the world running for cover, one French retailer can justifiably feel that more than 40 years of working alongside food producers has been vindicated, writes Peter Crosskey.

Seafood is among the most traded food commodities in the world, and growing, writes istein Thorsen, trie principal consultant.

Freshwater prawns, Machrobrachium rosenbergii, or shrimp are currently popular with small scale aquaculturists in the southeastern United States. Pond acreage has been constructed in nearly all states, but particularly in Kentucky, Mississippi, Texas, Tennesse…

As the worlds population heads towards the 9.3 billion mark, predicted for 2050, the demand for fish products is also expected to grow. However, there are questions about the ability of marine fisheries and aquaculture to match increasing consumption rates. Aq…

The pace of Chinas aquaculture development has been stymied by a slowdown in demand (both domestically and abroad). The future of South Chinas aquatic industry rests on more than just safety or price, but on the establishment of sustainable fisheries practices…

Roy P.E. Yanong, University of Florida IFAS extension, discusses the fish health management in recirculating aquaculture systems. As Part 2 of a three part series, this article looks at the role of pathogens (potential disease-causing organisms) in recirculati…

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 …

USDA, along with the American Soybean Association (ASA) and the Fisheries Development Board (FDB), has funded a three year aquaculture project FEEDing Pakistan with an initiative to improve the livelihood of Pakistan farmers and consumers through increased aqu…

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 …

This factsheet published by the Southern Regional Aquaculture Center (SRAC) gives information on the principles of fish nutrition.

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

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.…

Roy P.E. Yanong, University of Florida IFAS extension, discusses the fish health management in recirculating aquaculture systems. As Part 1 of a three part series, this article gives and introduction to management including biosecurity and water quality.

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.

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…

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…
