The role of aquaculture in meeting global demand
In many parts of the world, aquaculture is already playing a central role in getting fish to the table. Not only does it allow for a greater number of fish to be produced, it can reduce fishing pressure on wild stocks. The FAO has reported that aquaculture was responsible for 46.8% of the global fish supply in 2016, up from just 25.7% in 2000. However, to meet future demand, and to keep the practice sustainable, new approaches to aquaculture are required.
A major trend in the aquaculture industry is towards larger cage nets, which can not only house a greater volume of fish, but also help to ensure that fixed costs such as labor, equipment and repairs are lower relative to the volume of farmed fish.
However, larger nets can introduce a number of new challenges. When made with traditional nylon, they can become much heavier and harder to handle, thereby requiring additional equipment and personnel. These nets – typically up to 160m in circumference – can weigh more than four tons, while their greater surface area means that they require more inspections and repairs.
Facing these challenges, many in the aquaculture industry are looking to increase cage size, without exposing themselves to extra risks. The solution for many lies in cage nets made with Dyneema®, the world’s strongest fiber.
