Water Quality Monitoring and Management for Catfish Ponds
Any fish farmer that wants to record a high survival of fish and better growth in record time in their ponds must endeavour to pay good attention to pond water quality, writes Lanre Ogunsina....
Food Loss: Questions About the Amount and Causes Remain
Two-thirds of the 133 billion pounds (5.9 million tonnes) of food loss in the US in 2010 occurred in homes, restaurants and other place outside the home, and one-third occurred in grocery stores and other food retailers, according to a new report from...
Nile Tilapia Genetic Improvement: Achievements and Future Directions
This is a review by Hans Komen, Wageningen University, Netherlands and Trinh Quoc Trong, Research Institute for Aquaculture, Viet Nam, of the current developmental state of Nile tilapia selective breeding programs, most of which have focused mainly on...
Improving Productivity and Environmental Performance of Aquaculture
Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than...
Genetically-Improved Tilapia Strains in Africa: Potential Benefits and Negative Impacts
Two genetically improved tilapia strains (GIFT and Akosombo) have been created with Oreochromis niloticus (Nile tilapia), which is native to Africa. In particular, GIFT has been shown to be significantly superior to local African tilapia strains in terms...
Milestone Made in Salmon Research – Genome Fully Sequenced
The complete genetic code was made public at an international conference in Vancouver on 10 June. Fully sequencing the Atlantic salmon genome is a landmark achievement – and provides a wellspring of new opportunities for scientists and the aquaculture...
Large-Scale Deployment of Fish Aggregation Devices Alters Environmentally-Based Migratory Behavior of Skipjack Tuna in the Western Pacific Ocean
Fish aggregation devices (FADs) have been used extensively in the tuna purse seine fishery since the 1980s. This long-term modification of natural habitat has generated discussions as to whether FADs impact movement patterns of tuna species. Xuefang Wang...
Progress and the Future for Tilapia Farming and Seed Production in Bangladesh
Tilapia is globally recognized as one of the most important aquaculture species of the 21st century. Tilapia culture has expanded rapidly in a wide range of farming environments from extensive to intensive in both fresh and brackish water in Asia including...
Identifying Yellow Perch Gender to Improve Production
A plentiful supply of yellow perch was once available in the US Great Lakes region, but that changed in the 1990s. Populations of this Midwest fish-fry favorite dropped dramatically due to the invasion of the zebra mussel, overfishing, and other factors....
Fish Trade and Human Nutrition
The FAO paper from the 14th session of the Sub-Committee on Fish Trade reviews the role fish plays in human nutrition and looks at the impact fish trade might have on food security and nutrition. Fish is recognized as an excellent source of protein but...
Sociality Modulates the Effects of Ethanol in Zebra Fish
New findings published by researchers at the New York University Polytechnic School of Engineering are helping to unravel the complex interplay between alcohol and social behavior and may lead to new therapies for mitigating the negative impacts of alcohol...
The Interaction Between Water Currents and Salmon Swimming Behaviour in Sea Cages
Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study David Johansson et al, Institute of Marine Research, Norway, observed the swimming behaviour of Atlantic salmon...
Visual Thresholds for Feeding and Optimum Light Intensity for Larval Rearing of Asian Seabass
This study by Yukinori Mukai, International Islamic University Malaysia, and Leong Seng Lim, University Malaysia Sabah, examined the retinomotor responses and prey ingestion rates of 10-, 15-, 20- and 30-day-old Asian seabass Lates calcarifer under different...
The State of World Fisheries and Aquaculture 2014
In a world where more than 800 million continue to suffer from chronic malnourishment and where the global population is expected to grow by another 2 billion to reach 9.6 billion people by 2050 – with a concentration in coastal urban areas – we must...
Inbreeding and Disease in Tropical Shrimp Aquaculture: A Reappraisal and Caution
The disease crisis facing shrimp aquaculture may be propelled, in part, by an interaction between management practices that cause inbreeding, and the amplification by inbreeding of susceptibility to disease and environmental stresses. This study by Roger...
