Double duty: Seaweed provides both biofiltration, marketable product
Most seaweed species that function as biofilters for finfish aquaculture have little market value, so produced biomass remains a byproduct of biofiltration.
Greenhouse systems a promising technique against WSSV in Ecuador
CENAIM’s greenhouse production trials were carried out at the commercial Pesglasa shrimp farm, located in the Taura region of Ecuador’s Guayas Province.
Geographic variation among IHHNV isolates provides insights into pathology, spread
Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) has been detected in farmed shrimp stocks around the world.
Tetraploidization in Nile tilapia
Sterilization by induced triploidy is an effective method to suppress natural reproduction and therefore its stunting effect in Nile tilapia grow-out ponds.
Study evaluates IHHNV effects on Pacific white shrimp
Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) reduces the growth and survival rates of Pacific white shrimp.
Fingerling production still bottleneck for cobia culture
Production of cobia (Rachycentron canadum) is growing rapidly in Asia, yet fingerling production predominantly occurs in extensive pond environments.
Induced triploidy research in fleshy shrimp may lead to improved production
Authors carried out a series of studies on polyploid induction in fleshy shrimp, one of the most important commercial shrimp species in China.
Avoiding genetic bottlenecks in broodstock selection
Broodstock selection programs for Atlantic halibut identify top first-generation performers to develop a strain best suited to aquaculture conditions.
Success factors in marine fish culture
Harbor Branch Oceanographic Institution researchers have developed marine fish culture methods on an experimental to pilot scale.
Starvation timing affects morphology, growth of first-feeding halibut larvae
The authors recently evaluated the physical deterioration of first-feeding California halibut larvae using morphometric and histological criteria.
Linking mapping for Kuruma prawns
Domestication and genetic improvement of the Kuruma prawn (Penaeus japonicus) have been relatively slow due to availability of broodstock and postlarvae.
Influences of dietary factors on fish health
Proper nutrition is crucial to maintain growth and health in farmed fish. A variety of dietary factors and nutritional strategies can be influential.
Concerns over antibiotics, chemicals in aquaculture
When an antibiotic is administered, the usual effective dose may be insufficient to control an infection if the invasive microorganism has developed resistance.
CENAIM study examines effects of transport on shrimp postlarvae survival
The cumulative effects of shrimp hatchery harvest, packing, temperature change, transporting and acclimation have an impact on postlarvae survival.
Size-grading experiments yield strong advice for tilapia hatcheries
In an experiment in which tilapia were sorted by size and reared separately, large individuals maintained their size advantage after eight weeks of culture.
Israeli study examines feeding regimes for Asian sea bass grown at high temperatures
Asian sea bass (Lates calcarifer) feeding strategies and diets must be developed for slow-growth (winter) and fast-growth (summer) seasons.
