High Survival Rate for Post-Smolt in Closed Facilties
Problems with lice and losses can be heavily reduced by placing farmed fish in closed systems until the fish reach a weight of one kilo. This has been shown by research conducted by scientists at Uni Research in Bergen, Norway....
Helping Salmon Cope with Stress of Transfer to Sea
Scientists are keen to sort farmed salmon and provide them with exercise right from the early stages of their growth, in order to equip them to deal with the stress of transfer to the sea....
How to Achieve Good Water Quality Management in Aquaculture
Water quality is the most important factor affecting fish health and performance in aquaculture production systems. Good water quality refers to what the fish wants and not what the farmer thinks the fish wants. This means that farmers must understand...
Effects of Bamboo Charcoal Added Feed on Reduction of Ammonia and Growth of Pangasius
A 50-day feeding trial was conducted to determine the effects of dietary bamboo charcoal (BC) on ammonia (NH3-N) excretion and growth performances of Pangasius hypophthalmus, write M Sadiqul Islam et al, Bangladesh Agricultural University. ...
Hatchery Management and Tilapia Fingerling Production
This guide from Infonet-Biovision provides easy to follow information on hatchery management and tilapia fingerling production....
Marine Shrimp Biofloc Systems: Basic Management Practices
This publication summarizes basic management practices for the majority of farmers raising marine shrimp (Litopenaeus vannamei) in Indiana, US, based on the most current literature available, writes Robert Rode, Purdue University....
Economic Costs of Protistan and Metazoan Parasites to Global Mariculture
In this study, Andy Shinn et al, Fish Vet Group, Thailand, examine the world’s major marine and brackish water aquaculture production industries and provide estimates of the potential economic costs attributable to a range of key parasite pathogens...
A Touch of Clay Helps Prevent Deadly Fish Disease
A type of clay used in cosmetics, medicine, and papermaking may be just what aquaculture farmers need to fight columnaris—a costly and deadly bacterial disease that affects freshwater finfish worldwide, writes Sandra Avant, USDA, ARS....
How to Construct a Semi-intensive Pond for Aquaculture
This guide from Infonet-Biovision provides easy to follow information on how to build a pond for fish farming including findding a location, water inlets, pond size and costs....
Bath Vaccination of Rainbow Trout Against Flavobacterium Psychrophilum
Effective bath immunization systems may be very helpful to the salmon industry, particularly during the freshwater growth stages in which vaccination through injection is not possible, write Dr Juan Battaglia Aljaro, Velásquez S. and Ilardi P., Veterquímica...
Influence of Isthmus of Panama in the Evolution of Freshwater Shrimps in America
The evolution of freshwater shrimps species living in both sides of Central America, isolated by the closure of Isthmus of Panama (3 million years ago) were studied by molecular tools....
Water Quality Parameter Analysis for the Feasibility of Shrimp Culture
Muhammad Kasnir et al, Indonesia Moeslim University, Indonesia, carried out physicochemical studies to asses water resource in Mangara Bombang District, South Sulawesi in relation to their potential for shrimp aquaculture use....
Effects of Nitrite Exposure on Rabbitfish
Nitrite is toxic to fishes and is often encountered in recirculation aquaculture systems. Accordingly, the nitrite tolerance of potential aquaculture candidates needs to be assessed before the fish can be farmed in land-based recirculation systems. In...
Fish 'Personality' Linked to Vulnerability to Angling
Individual differences in moving activity in a novel environment are linked to individual differences in vulnerability to angling, according to an experimental study completed at the University of Eastern Finland and the Finnish Game and Fisheries Research...
Scientists Discover New Mechanism for Sex Control in Zebrafish
New research has discovered that the reduction of gonadal stem cells will yield more male zebrafish. The findings, by László Orbán et al, Temasek Life Sciences Laboratory, suggest that a stem cell counting mechanism in the zebrafish gonad is important...
