Fish needs – doing it right by the farmed fish AND the environment
Tides Canada, Uncommon solutions for the common good.
5 September 2013
This is the second in a series of guest blogs from the 5th Aquaculture Innovation Workshop, organized by Tides Canada’s Salmon Aquaculture Innovation Fund that focuses on advancing aquaculture solutions which protect wild salmon and the marine environment.
A fish out of water is usually a bad thing, but today, global expertise was shared in how a fish raised in tanks on land can be very happy indeed, leading to production rewards for fish farmers in addition to environmental sustainability.
The Aquaculture Innovation Workshop series organized by Tides Canada and partners, is aimed at sharing expertise to advance the adoption of closed-containment systems as a means to meet the growing global demand for seafood while protecting the environment and conserving wild fish stocks.
Day 1 of Aquaculture Innovation Workshop #5 (AIW5) focused on how raising fish in closed containment provides the opportunity for optimal conditions to be achieved, maximizing fish welfare, growth and product quality.
Presenters from nine international research facilities shared their work in determining optimal fish welfare conditions and how these conditions can be controlled when fish are grown on land including: swim speed, photoperiod, and levels of oxygen, pH, salinity, carbon dioxide, temperature, solids, fish hormones, and ammonia.
Collaboration in sharing successes and challenges means that the technology to maximize fish welfare can be accelerated, and that’s good news for everyone.
Growing fish on land gives control over contact with the environment as well as the conditions that optimize farmed fish welfare. The wild fish benefit, the farmed fish benefit and, ultimately, the fish farmers benefit since better fish welfare means better growth rate and feed conversion.
And that’s a really good thing since environmental solutions need to be economic to stick.
