– Aquaculture feed – Aquaculture feed

[Music plays] The global aquaculture feed market is becoming increasingly significant, producing close to 40 million metric tonnes of feed a year. Fish feed is very expensive, and high quality compared to other animal feeds. That means the ingredients need to be fine-tuned to save manufacturers and producers thousands of dollars a year. The University of Guelph is one place where this is happening. Animal and Poultry Science professor Dominique Bureau and his research team, including post-doctoral fellow Kabir Chowdhury, are developing more cost-effective manufacturing processes to make feed ingredients nutrient efficient. They’re focusing on making phosphorus more easily digestible because it’s an important mineral in the fish diet, but expensive to supplement. In fact, the researchers have found that processing the feed significantly increases the amount of phosphorus that fish are able to digest. Well processing the ingredients will reduce the level of indigestible nutrients, indigestible components in the feed. So for every feeding with a certain amount of ingredients, you’ll have less waste associated. Also by improving the digestible nutrient content of the ingredients, you can better balance the diet. The team is also tailoring the ingredients to different fish species. They’re separating poultry meal, a common component of fish feed, into high protein and low protein content. Next, they’re aiming to use these components to target two fish markets. One for fish requiring high levels of protein, and one for fish requiring lower levels. The researchers say improving nutrient digestibility means greater profits all along the supply chain for farmers as well as meat, grain and food processors, and creating species specific feeds benefits fish diets, and the industry as a whole. Our model species is Rainbow Trout, because it is the species most cultured in Ontario, but the production of rainbow trout in Ontario is very small, so we’re aiming for the world market. Canada is a major producer of salmon around the world, but there’s also a huge market abroad in carp feed, tilapia feed, and shrimp feed, so we really have a global outlook and we think we can tailor the product to different species in different parts of the world. Bureau already has close industry and research partners in Ontario, as well as abroad in Asia, South America, and Mexico. As a result, their findings are being quickly adopted in domestic and international manufacturing processes, and are already helping to improve feed profitability. With international outreach, Bureau hopes that his processing techniques will have global implications. of less waste and cleaner waters. Helping to keep fish as healthy as they can be.
