What is one advantage of using raceways over net pens?

Using raceways offers a distinct advantage in terms of the reduced risk of escape and predation. Raceways are enclosed systems that provide controlled environments for fish farming. This physical containment greatly minimizes opportunities for fish to escape into the wild, which is a significant concern in aquaculture practices, as escaped fish can disrupt local ecosystems and compete with native species.

In addition, the design of raceways helps protect fish from natural predators, such as birds or other wildlife, that can easily access net pens. By limiting both escape opportunities and the threat from predatory species, raceways promote a healthier farming operation, which can lead to better survival rates and overall productivity in aquaculture practices. This controlled environment also allows for better management of fish populations and health, further enhancing the viability of fish farming.
