Cultivated bivalves rely on natural seston for growth and metabolic processes. Because seston is a limited resource, there is a need to better understand its distribution and fluxes within culture embayments, so farms can be positioned optimally within these d…

Although aquaculture in the Mediterranean is a relatively young industry, finfish diseases have been reported to cause considerable problems and mortalities among the farmed stocks. In response, P. Arechavala-Lopez et al, University of Alicante, Spain, focus o…

Water temperature control to optimize fish growth is one the deciding factors favoring land - based aquaculture. Maintaining optimal temperature for growth removes the seasonal variations often found in fish feeding and growth rates as temperatures change, wri…

This FAO document is a practical guide that includes a list and the technical details of materials to construct a hexagonal wooden cage for fish farming, and its mooring system, for use in artisanal aquaculture. Instructions for assembling the various componen…

In the context of resource management and spatial planning, tools are needed to help decision makers assess the potential of coastal areas for various activities. Among these, shellfish culture presents the particularity of exploiting natural resources as well…

Tra catfish (Pangasius hypophthalmus) is a dominant cultured species in Vietnam in terms of production. Its aquaculture production in 2011 was approximate 1.2 million metric tons. The main culture system for tra catfish is intensive model in earthen ponds with…

With a need to guarantee complete coverage of fish cages during an inspection to prevent escapees through damaged net, Per Rundtop et al, SINTEF, have studied underwater vehicle navigation systems for net inspection in salmon aquaculture.

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…

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…

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…

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 …

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…

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…
