Feeding the world through sustainable fish farming
Up to 40 million metric tonnes of seafood will be required by 2030 to feed the world’sgrowing population. By this time, over 60 per cent of seafood will come from aquaculture, or farmed fish stocks. Therefore, aquaculture will be instrumental to meet the global demand for seafood in the future.
Good nutrition is critical for the health, growth, reproduction, and quality offarmed fish. A major challenge in aquaculture is making sure that fish are provided with adequate nutrition to yield a healthy nutritional source for consumers, while ensuring minimal negative impact on the environment.
This balance is difficult to achieve since aquaculture feed typically contains marine ingredients that are harvested from wild fish populations.
The goal of Stefanie Colombo’s research, as Canada Research Chair in Aquaculture Nutrition, is to discover novel solutions to improve nutrition and aquaculture production, without harming the environment.
Specifically,Colombo is focusing on: identifying novel and sustainable nutrient sources in aquaculture feeds; improving the efficiency of these nutrients by balancing themoptimally in the diet; and understanding how warming waters from climate change impact nutritional sources and their metabolism by farmed fish.
The knowledge gained from Colombo’s research will be critical to creating new aquaculture feeds that do not depend onlimited marine resources and have a minimal impact on the environment. This work is important for the sustainable development of the aquaculture industry while meeting the food needs of an expanding world population.
