Lumpfish: The Latest Weapon in the Battle Against Sea Lice?
The ongoing battle to combat sea lice remains one of the major issues facing salmon farmers of today. The parasite poses a significant threat to aquaculture operations worldwide. Whilst a number of preventative methods and post-infestation treatments,...
An Overview of Heating and Cooling Process Water in Land-based Aquaculture
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,...
The Use of Algae in Fish Feeds as Alternatives to Fishmeal
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...
Reared Fish, Farmed Escapees and Wild Fish Stocks — A Triangle of Pathogen Transmission of Concern to Mediterranean Aquaculture Management
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,...
Biochemical and Molecular Heterogeneity Among Isolates of Yersinia Ruckeri from Rainbow Trout
Enteric Redmouth Disease (ERM), caused by Yersinia ruckeri, is one of the most important infectious diseases in rainbow trout (Oncorhynchus mykiss) aquaculture in Europe. More recently, non-motile vaccine resistant isolates appear to have evolved and...
Effects of Sangrovit on the Performances of Tra Catfish Cultured in Earthen Ponds
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...
Eco-Label Conveys Reliable Information on Fish Stock Health to Seafood Consumers
Concerns over fishing impacts on marine populations and ecosystems have intensified the need to improve ocean management. One increasingly popular market-based instrument for ecological stewardship is the use of certification and eco-labeling programs...
Diagnostic Method for Assessing the Shellfish Culture Potential of a Coastal System
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...
Construction and Installation of Hexagonal Wooden Cages for Aquaculture
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...
Underwater Vehicle Navigation Systems for Net Inspection in Salmon Aquaculture
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....
A Review on Population Characteristics of Gilthead Seabream
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...
Importance of Feed Enzymes for Shrimp and Fish in Sustainable Aquaculture
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...
Behavioural Disturbances in a Temperate Fish Exposed to Sustained High-CO2 Levels
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...
Immunomodulation Properties of Bacterial Meal Grown on Natural Gas Against Soybean Meal-Induced Enteritis in Salmon
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...
Influence of Developmental Stage and Genotype on Liver mRNA Levels Among Wild, Domesticated, and Hybrid Rainbow Trout
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 developmental...
