In southern Brazil, management data for Pacific cupped oyster culture were assessed to characterize production in relation to environmental parameters.
In a nutrition trial, longfin amberjack received two diets composed of 40 percent soy protein concentrate and 10 percent fishmeal, and a control diet with 20 percent fishmeal.
The absence of practical immediate-release sedatives for fish jeopardizes fish, fisheries, fish culture and research, posing risks to aquatic resources as well as those handling fish.
Single-cell detritus is a seaweed-based bioproduct whose use as feed has been studied with oysters and artemia. The authors are working toward the development of SCD for shrimp larvae.
Granulomas in diseased fish often indicate infections by bacteria. External signs range from ulcers and emaciation to lethargy or no signs at all. Internally, gray or tan foci present in organs and can coalesce with severe inflammation.
Accurate estimates of shrimp populations and size variability by sampling can help managers make informed decisions that reduce feeding costs and improve system performance.
The PescaMaris shrimp farm in Ecuador uses fish peptide isolates to accelerate probiotic bacteria growth and improve water quality.
Prevention through good hygiene, use of gloves and basic biosecurity procedures is the best method for reducing the risk of acquiring zoonotic diseases.
Smolt production in Norwegian hatcheries will likely increase during the next decade to answer salmon grow-out needs. Farmers are converting existing flow-through systems to partially or fully incorporate recirculation technologies.
Thailand’s tilapia industry has been able to grow into a thriving sector thanks to technological advances and knowledge sharing.
In a challenge test under controlled conditions using a severe strain of the virus, resistance to WSSV was shown in shrimp supplied by the Camaronera de Coclé, S.A. L. vannamei genetics program.
The University of Arizona’s Aquaculture Pathology Laboratory oversees ring tests for a group of shrimp diagnostic laboratories in 10 countries.
The authors designed changes for single- and twin-screw extruders that streamlined the extrusion process to achieve higher output rates for small-diameter aquafeeds.
In a study with pangasius, dietary administration of a blend of botanical extracts improved performance, reducing intensity of gill parasite infestation.
Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.
In a 10-week study of nursery-reared Pacific white shrimp performance, the inclusion of Spirulina meal allowed reduction of fishmeal up to 25 percent with no detrimental effect on shrimp growth performance.
