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.
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.
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.
Closed-cycle, controlled environment systems: the Solar Aquafarms story
Solar Aquafarms developed an innovative, low-cost method for growing fish and shrimp in closed-cycle, controlled environments in California.
Culture of southern flounder in a freshwater recirculating system
Researchers conducted the first experimental nursery and grow-out trials of southern flounder in a raceway using a freshwater recirculating system.
Recirculation technologies in Norwegian aquaculture
Availability of quality fresh and saline water in Norway has contributed to the fact that recirculation technologies are considered uneconomical.
Commercial production of sea bream fingerlings in Spain
Sea bream fingerling producers have had to modify their facilities to grow larger animals by increasing tank volume and water flow.
Changing paradigms in shrimp farming, part 4
In high-density systems with zero water exchange, pond ecology shifts from an autotrophic, phytoplankton-based microbial community to a heterotrophic, bacterial-based community.
