Aquaculture Innovation in Asia

Categories: Latest News

As chairman of Caribbean Sustainable Fisheries and active aquaculture advocate, I recently came across this article that struck a chord with me.

I’m always looking for new and innovative ideas when it comes to fish farming, and I think Hong Kong is definitely onto something.

Taking fish farms out of the water and building them vertically in high-rise buildings could very well be the go-to aquaculture option of the future.

Before I go into these high-rise fish farms, let’s explore the realities of modern-day fish farming…

Open Systems: The Problem With Fish Farms In The Water

Aquaculture under the right conditions can be a viable part of meeting the demand for seafood and replenishing stocks. However, open aquaculture systems come at the expense of a healthy ocean.

Fish farms are often built directly in the water. The fish are stocked, fed and harvested within cages located in open water and anchored to the ocean floor, until they reach market size.

This type of fish farming is controversial because of its heavy impact on the environment. It negatively affects the ecosystem because it allows for an unregulated exchange between the farm and its surroundings.

For example, fish feces and high concentrations of waste fall to the ocean floor below the cage, killing the sea life below it. Chemicals from feeding, parasites and diseases end up in the water system impacting life around it.

There’s no question that we need fish farms (diminishing stocks, higher demands, etc.) so the question is how to do it without hurting the environment?

Luckily, there’s new advancements that will allow aquaculture to thrive without the negative consequences.
