Aquaculture

Feed cost shares the highest proportion in aquaculture production cost. It could range from 40 percent to 70 percent of the total cost. Insects can convert agricultural food wastes into larvae and these larvae can be fed to aquatic animals, potentially reducing feed costs. More and more companies are producing the larvae of insects such as mealworms and black soldier...
Today, tilapia is the second most cultured fish species in the world. After 28 years of selective breeding, WorldFish’s genetically improved farmed tilapia (GIFT) is now producing its twenty third generation and is being used by 17 governments around the world. The GIFT strain has improved by nearly 10 percent in growth performance per generation. The selective breeding method has...
Despite all the potential nutritional, industrial, environmental, economic and employment benefits of seaweed aquaculture, seaweed productivity is declining in many areas of the world because of climate change impacts, resulting in more frequent seaweed disease outbreaks.  While biosecurity protocols to minimize the likely risk of introduction and spread of disease pathogens and pests are applied to the production of most...
Integrated multitrophic aquaculture (IMTA) generates both environmental and economic benefits in China, where it accounts for 40 percent of the country’s mariculture production. IMTA involves farming two or more aquatic species from different trophic levels together to improve efficiency, to reduce wastes and to provide ecosystem services. The key driver for the move to IMTA in China was pollution by...
Over 90 percent of shrimp feed production in Asia is still based on the use of lower-cost compression-based pelleting techniques. Nutritional and economic superiority of using extruded shrimp feeds has been known for almost two decades. Shrimp fed with sinking extruded feeds display higher growth and improved feed conversion efficiency compared to shrimp fed with conventional pelleted feeds. The main...
