Find protein sources for aquaculture

Lack of fish meal to produce aquaculture feeds, farming will have to rely on advances in the development of alternative sources of protein from plants, algae and even insects.
That is the analysis of TS. Says Sara Olson, senior analyst at Lux Research, sara.olson@luxresearchinc.com. According to TS. Olson, the global aquaculture industry with a current value of $ 170 billion, may face a shortage of fishmeal and fish oil as raw materials for industrial feed production in early 2016. , the difference between supply and demand is forecast to reach 16 million tons by 2025. Alternative sources of protein derived from plants, algae and even insects will therefore play an important role in addressing part of this shortage. The minimum requirement is 1 million tons of high quality protein.
Currently, the demand for fishmeal and fish oil for aquaculture is up to 8% per year. Replacing fishmeal with other protein sources is still difficult due to low production and high production costs. The price of fishmeal increased by about 10% a year, the price of soybean meal doubled compared to 2007, which has led to the increase in feed prices recently and will continue to increase in the future.
Exchange of TS. Olsen has not mentioned protein source from bacterial biomass. There are a number of experimental studies on the production of microbial biomass from wastewater from fish and prawn ponds, as a source of dietary protein. Interestingly, some bacteria have the ability to stimulate the growth of fish and shrimp. Countries that have to import fishmeal in the future will have to find ways to develop indigenous protein sources, looking for lower protein needs, or balancing extensive (based on natural food) with intensive farming area.
