Aquaculture of pelagic fish, part 3
Supporting the global growth of pelagic fish aquaculture will require more efficient, cost-effective and environmentally sustainable methodology.
Broodstock management of summer and southern flounder
Along the eastern U.S., two highvalue flatfish species – summer flounder and southern flounder – are top candidates for commercial grow-out.
Culture of red snapper
At the Gulf Coast Research Lab in Mississippi, red snapper have been reared during the past three summers and released offshore for two years.
Bullfrog farming: Comparison of inundated and semi-dry ongrowing methods
Bullfrog farming has developed from extensive, single-crop, low-yield methods to intensive, economically viable, multiple-crop systems.
Chlorine and fish processing
Chlorine is used in fish processing to prevent contamination by waterborne pathogens and to reduce the incidence of cross-contamination.
Advances in tilapia broodstock management
Female tilapia broodstock spawn asynchronously, producing only 2,000 eggs per clutch. Hatchery operators often run into low seed quantity and quality problems.
Evolution of processed tilapia products in the U.S. market
Processed tilapia is continuing to improve as international growers upgrade their production, processing and transportation systems.
Design considerations for a modern shrimp-cooking facility
Grupo Granjas Marinas built a shrimp-cooking facility adjacent to its processing facility in Honduras and replaced its refrigeration equipment.
Mechanized shrimp harvesting
This article describes a mechanized shrimp harvesting that consistently yields quality product suitable for the European market.
Aquaculture of Asian sea bass or barramundi
The Asian sea bass (Lates calcarifer) is known by various common names in different parts of its range, including “barramundi” in much of Asia.
Aquaculture in Vietnam
Vietnam introduced its “Doi Moi” program of economic reform in the mid-1980s, effectively establishing an open-door policy for outside investment.
Aquaculture of pelagic fish, part 2
Australia’s aquaculture industry is developing rapidly, fueled by southern bluefin tuna (Thynnus maccoyii) in offshore net cages.
Recirculating aquaculture systems in freshwater salmon hatcheries
With improvements in water recirculation technology, the time has come to seriously consider RAS in a freshwater salmon hatchery.
End-of-pipe water treatment at salmonid hatcheries in Norway
Most of the approximately 250 Norwegian salmonid hatcheries are located on the coast and close to a freshwater source.
Advances in fluidized sand bed biofilters
New designs for fluidized sand bed biofilters have improved hydraulic efficiency, reliability, installation costs and maintenance.
Treatment of recirculating waters with floating bead bioclarifiers
Bead filters compete very well as bioclarifiers and are used in combination with fluidized beds to tackle solids capture and biofiltration needs.
