Aquaculture Overview

Although livestock is very popular, it is not the only source of animal protein. Poultry and aquaculture are other sources which some argue are environmentally safe with little to no greenhouse gas emission as is the case with livestock farming. According to the United States Department of Agriculture, healthier dietary choices has led to a rapid growth in the United States aquaculture industry which is currently estimated at over $2 Billion. The Food and Agriculture Organisation reports that the global fisheries industry grew by over 500% between 1990 and 2018, and is projected to surpass a market value of $200 Billion within the next 5 years. However, experts have identified climate change and sustainability issues, limited expertise, rising inflation rates, shortage, and high costs of input and low technological infusion as a few setbacks to the industry’s growth.
In dealing with the shortage of input supply, particularly high cost of feed, practitioners are exploring insects as an alternative. Currently, most fish feed are composed of soybean, wheat and rice which are highly demanded by humans and the livestock industry.

This puts a strain on the already stretched food supply chain. However, adopting insects would serve as a good source of cheap and readily available protein which is less injurious to the environment. Ynsect and Hexafly are companies in Europe currently driving insect-feed alternative in aquaculture. Tengrain Science on the other hand is involved in facilitating the involvement of local farmers and other value-chain actors in aquaculture.
