Most of the approximately 250 Norwegian salmonid hatcheries are located on the coast and close to a freshwater source.
New designs for fluidized sand bed biofilters have improved hydraulic efficiency, reliability, installation costs and maintenance.
Bead filters compete very well as bioclarifiers and are used in combination with fluidized beds to tackle solids capture and biofiltration needs.
Solar Aquafarms developed an innovative, low-cost method for growing fish and shrimp in closed-cycle, controlled environments in California.
Researchers conducted the first experimental nursery and grow-out trials of southern flounder in a raceway using a freshwater recirculating system.
Availability of quality fresh and saline water in Norway has contributed to the fact that recirculation technologies are considered uneconomical.
Sea bream fingerling producers have had to modify their facilities to grow larger animals by increasing tank volume and water flow.
In high-density systems with zero water exchange, pond ecology shifts from an autotrophic, phytoplankton-based microbial community to a heterotrophic, bacterial-based community.
