I’m the hatchery supervisor for GĂ„rdsfisk, a land-based fish-farming firm in southern Sweden. Standard fish farming within the sea can have huge environmental and welfare impacts. Fish can escape from their enclosures, they’ll unfold illness, and waste from the farms can over-fertilize waterways and damage aquatic ecosystems. Our goal is to provide essentially the most sustainable fish on the planet.

We farm crimson and silver tilapia and clarias, a sort of catfish, and develop our fish indoors on a farm utilizing a recirculating aquaculture system. The entire water quantity in our system is 2,000 cubic metres, lower than in an Olympic swimming pool. We use the fish faeces within the waste water from our tanks to fertilize surrounding farmland, and we reuse the tank water on our personal gardens to cut back our environmental footprint. We use renewable power wherever doable: our fish-farming buildings are lined with 600 sq. metres of photo voltaic panels. In summer time, when we have now as much as 18 hours of daylight a day, the panels can produce all of the electrical energy we’d like.

My job is to pick out the most effective breeding inventory. On this picture, I’m learning the broodstock, that are separated by intercourse into holding tanks in order that they don’t breed. The white containers are for feeding however they aren’t related; we hand-feed our brood inventory in order that we will examine on their welfare a number of instances day by day. The black barrels are for accumulating fish faeces. My gumboots are a part of our biosecurity measures; parasites can turn into an issue.

Earlier than we introduce breeder fish to our spawning tanks, we observe each to decide on the most effective, going by their fee of development, their basic look and the standard of their oocytes or sperm.

What I like about my work is that I can achieve this many alternative issues in a day. I will be harvesting or grading fish within the morning, and talking to South American clients within the afternoon. In August, we obtained a go to from the king and queen of Sweden.
