Temperature is one of key environmental parameters that affect the whole life of fishes and an increasing number of studies have been directed towards understanding the mechanisms of cold acclimation in fish.

The detection of pathogens at early stages of infection is a key point for disease control in aquaculture. This work by Dagoberto Seplveda et al, University Catlica de Valparaso, Chile, aims to design a unique RT-qPCR assay for pathogen detection in the three …

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…

Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year, writes Nathan Atkinson, MSc Sustainable Aquaculture Systems student, Fish Nutrit…

Fishmeal is very extensively used in feeds for fish as well as other animals. A recent global survey estimated aquaculture consumption of fishmeal at 3724 thousand tonnes in 2006 (Tacon and Metian 2008). Now it is becoming increasingly evident that such contin…

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…

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…

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…

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…

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…

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 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…

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…

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…

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…
