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...
Small fish, huge impact
2022
WorldFish under MYSAP programme promoted the production of dried powder made from small indigenous fish species and piloted portable fish driers, designed to reduce contamination risks. The drier keeps the fish covered while drying them, thereby reducing the contamination risk and the pilot test demonstrated improved safety. The dried small indigenous fish powder was promoted as a complementary food for infants of six months onwards to achieve better nutrition in Bangladesh, Cambodia, Myanmar and...
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...
Defining and implementing a tilapia welfare assessment protocol in Brazil
2022
Although welfare protocols for fish have been developed in the past, indicators are species specific and peer-reviewed journals do not contain any tilapia welfare protocol assessments. The new tilapia welfare assessment protocol was disaggregated into four aspects: health, environment, behaviour and nutrition. If any problem regarding any of these aspects is found, actions need to be taken to improve it, resulting in better welfare. The researchers behind a practical welfare assessment protocol for tilapia...
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...
The rise of plant-based seafood
2022
Plant-based for seafood are being produced using a range of ingredients and processes. The growth of the sector has largely been spearheaded by start-ups, many of which claim to be providing an ethical and sustainable alternative to farmed and wild-caught seafood. As the sector evolves, it is now also beginning to attract the attention of corporate food producers. Currently, plant-based seafood is not widespread globally, with the bulk of producers being based in high-income...
Sustainable intensification of aquaculture using efficient nanobubble technology
2022
To intensify production, it is common for aquaculture producers to aerate water in production systems. Efficient distribution of dissolved oxygen in the production unit is important to avoid stress and crowding behaviour. Most mechanical aeration systems agitate the water surface to increase oxygen levels and as a result dissolved oxygen levels are highest near the water surface and aquatic animals may aggregate and crowd in areas where oxygen levels are highest. Commercial companies have...
Rabbitfish farming in Asia
2022
The document is a brief of showcase of a specific aquaculture innovation. It contains main information on the technique and approach used, scope and scale of application, accessibility and the outcome and benefits of the innovation. Rabbitfish are herbivorous fish native to the Indo–Pacific region. Most rabbitfish consumed currently come from capture fisheries. The high demand for these species is causing a decline in their numbers in the wild. Rabbitfish have considerable potential for small-scale...
The growth of single-cell protein in aquafeed
2022
This review describes the use of feedstock yeasts and bacteria for acquaculture feed, with an emphasis on those sourced from carbon dioxide, ethanol and brewery by-products for their comparatively low costs and sustainability credentials. The scope of application of single-cell protein based feeds and their outcome, are benefits are presented. Aquaculture competes with fish meal use in the diets of swine, poultry and pets, and fish meal production cannot match the growth of all...
Aquaculture's next frontier?
2022
The document is a brief of showcase of a specific aquaculture innovation. It contains main information on the technique and approach used, scope and scale of application, accessibility and the outcome and benefits of the innovation. Aquaculture has traditionally been carried out in freshwater and coastal areas. This causes pressures including competition for space from other activities, issues with disease and poor water quality and runoff carrying nutrients and pollution from other land-based activities. Increasing...
