As atmospheric CO2 levels rise, the CO2 concentration in ocean surface waters increases through a process commonly referred to as ocean acidification. Recently, surprising behavioural modifications have been detected in the early life stages of tropical coral …
The expansion of global aquaculture production is increasing the demand for aquaculture feeds. Fishmeal is the main and most critical ingredient in aqua-feed production. The increasing cost of fishmeal has encouraged feed manufacturers search for cheaper alter…
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…
For many farming practices, the capture, handling and transport of fish is an essential requirement; however with each of these activities found to be a stressful process, what are the implications for fish welfare? Hannah Chilvers, writing for TheFishSite.com…
Reports of product mislabeling are a constant story in the global seafood industry, with many advocating for more strict enforcement of naming requirements. The calls for more enforcement of seafood labeling rules begs the question of whether those rules achie…
The increased use of plant proteins as replacements of fish meal (FM) in aqua feeds may have adverse effects on nutrient digestibility, growth performance and gut health. Solvent extracted soybean meal (SBM), the major protein source in animal diets induces in…
S. aurata is a marine fish living along the Atlantic coasts of Europe and the Mediterranean Sea. It is an important food species, so that its production reached 128,943 t in the European aquaculture in 2008. However, little is known on its biology, in particul…
With a growing demand for alternative proteins to satisfy the nutritional requirements of fish, Julio Traub et al, Heriot-Watt University, Scotland, looked at the use of proteins from Malt (MW) and Grain Whisky (GW) co-products and presented their findings at …
Authors Dr David Graham and Dr Marian McLoughlin have commented on a recent study conducted by the Fish Diseases Unit (FDU) of the Agri-food and Biosciences Institute in Belfast and MSD Animal Health in Bergen, which has investigated relationships between diff…
A PhD project carried out at the Norwegian School of Veterinary Science has examined the unwanted discoloration, or melanin "black spots", of muscle fillets from farmed salmon.
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…
In order to gain more understanding of the link between slaughtering and meat quality, M. M. Viegas et al, University So Paulo, evaluated how different slaughtering methods for pacu influence the protein denaturation of frozen fillets stored for 180 days. The …
Speaking at Aquaculture Europe 2013, T. Ytrestyl et al, Nofima, Norway, discussed the effects that salinity and exercise have on the performance and physiology of Atlantic salmon postsmolts reared in recirculating aquaculture systems (RAS).
In the last years considerable attention has been paid on the use of seaweeds (SW) as a possible ingredient for aquafeeds. Red, green and brown SW can be taken from their natural habitat and brought to the shore by the action of winds and tides, write Maria Is…
More than 129 million child labourers in the world work in the agriculture sector, which includes fisheries, aquaculture, forestry and livestock. These girls and boys, between the ages of 5 and 17, are performing work that interferes with their education or da…
Enzymes are one of the many types of protein in biological systems. With pressure to find more sustainable sources of fish feed for aquaculture, researchers have been trying to improve the nutritional value of fish feed by enzyme supplementation, writes Prakas…
The role of heterotrophic and autotrophic nutrition in the early stages of giant clams is still equivocal. In particular, the significance of these two nutritional modes and the relative dependency of the clams at the early life stages are not clear, said Moha…
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…
To balance the conflicting demands to reduce reliance on marine-ingredients while maintaining growth performance and high product quality standards, fish nutritionists have begun investigating the use of cost-effective alternative ingredients. During Aquacultu…
The sustainability of fisheries and aquaculture is becoming a much talked about issue, but how often do we think about how fish is slaughtered? Hannah Chilvers, writing for TheFishSite.com, discusses different slaughter techniques and their impact on fish welf…
Capture fisheries resources from marine, fresh and brackish waters around the globe are facing decreased landings due to various reasons such as over-fishing, oversized fishing fleets, irresponsible fishing, fishing with highly efficient technologies in near-s…
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…
Careful financial management is essential for the success of an aquaculture business. While financial management is a complex topic that can be approached from many perspectives, some of the key questions that the manager of an aquaculture business must answer…
This factsheet by the Southern Regional Aquaculture Center (SRAC) gives information on biosecurity in aquaculture, focusing on recirculating aquaculture systems.
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.
CANADA - British Columbia's salmon-farming industry will get the full Hollywood treatment, for better or for worse, in an episode of Emmy-winning courtroom drama Boston Legal that was filmed on location at an exclusive B.C. fishing resort.
