The rediscovered potential of seaweed dietary additives
2022
The cellular structure of seaweeds comprises indigestible fibres or complex polysaccharides, which are used as thickening additives or gelling agents in a range of processed foods and in cosmetics, pharmaceuticals, nutraceuticals and other industries. To date, only a handful of seaweed species have been used commercially as animal feed additives. Two main reasons underpin the use of seaweeds as dietary additives are to bolster the immune system of farmed animals and to improve their...
Is the time ripe for using insect meal in aquafeeds?
2022
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 fly for use in aquafeeds, but the sector has a long way to go...
Gene editing in aquaculture
2022
The document is a brief of a specific aquaculture innovation. It contains information on the technique and approach used, scope and scale of application, accessibility and the outcome and benefits of the innovation. Gene editing holds significant potential to enhance selective breeding. While selective breeding has been successful, it is limited by the heritability of the trait. Gene editing also prevents interbreeding with wild fish should they escape from a farm and offers the potential...
