The growth of aquaculture

So it would appear that the increase in farmed fish is good for everyone. Well not quite, as fish farming has come in for some criticism  recently for its practices and reportedly the amount of antibiotics and other chemicals being used to keep the fish healthy and parasite-free.

But as a fast growing industry, there are bound to be pain points in its progression and at Arvia we believe we can contribute to its continued, safe growth.

Since 1980, the global amount of wild-caught fish for the oceans has remained constant at around 70 – 90 million tonnes per annum. But in the same period, farmed fish has grown fast and is projected to reach an output of 109 million tonnes by 2030 with a yearly value approaching US$50bn.

This therefore, is big business and notwithstanding the issues with both RAS and off-shore aquaculture, there’s no stopping it now.

Aquaculture methods

Fish are farmed either onshore – that is to say, in land-based (RAS) growing environments (often indoors) that mimic ‘wild’ conditions – or offshore, in large nets or containments placed in the sea.

In the latter case, these nets are normally grouped together in deep water so the current washes away the inevitable sinking debris from a large concentration of fish.

Both have advantages and disadvantages, and both can hugely benefit from the sort of water treatment that Arvia’s Nyex™ systems can deliver.
