Did you know that most animals are raised on fish? It’s true! Fish meal is the main source of protein in many animal diets. This includes your pets at home as well as farm animals and even farmed fish.
According to a United Nations FAO report in 2016, global fisheries produce around 168 million tonnes of fish each year. And that number keeps rising! Fish are plentiful and high in protein, around 65%, but there are two major problems with using fish for animal feed.
Problem #1: Food security
We use almost one-third of the world’s ocean fish catch for animal feed rather than human consumption. These smaller bait or “forage” fish are used to make meal to feed pigs, chickens, and farm-raised fish.
On average, it takes three to five pounds of fish meal to produce one pound of farm-raised fish.
In a world where almost 795 million people go hungry every day, this is a huge amount of quality protein that could be used directly and more efficiently to address human food security.
Problem #2: Ecological damage
Fish are fundamentally important to the overall health of our oceans. Forage fish are at the foundation of the marine ecosystem, nourishing larger fish, marine mammals, and sea birds.
With the increase in fish catch every year, we are seeing major species disappearing and many fisheries closing. Why? We’re over-fishing and not allowing fish populations to recoup. Once abundant species are becoming endangered or being killed-off altogether.
The price of fish meal has increased 200% in the last ten years, and the demand is expected to outpace supply in the very near future.
Even as the aquaculture industry is pushed to implement and regulate more sustainable practices, there remains a critical need for quality alternative protein sources that are safe, plentiful, and affordable.
Soldier flies to the rescue!
Enter the black soldier fly, nature’s miraculous little bug that is revolutionizing the food and feed industry.
Yes, a fly! Black soldier flies (Hermetia illucens) are disrupting the aquafeed game as a low-cost, high-protein, alternative to fish meal.
Currently, BSF larvae are the only insect approved for use as feed for one group of commercially-raised animals: salmon, trout, and their relatives. The amino acid profile of BSF meal is very similar to that of fish meal, making it an ideal protein source for aquaculture rations.
The black soldier fly is not a pest to humans or other animals and uses its natural bio-conversion ability to upcycle the food waste it consumes into valuable proteins, fats, and chitin.
BSF production is a naturally sustainable and environmentally-friendly process compared to resource-intensive feed stock alternatives.
Soldier Fly Technologies is proud to be contributing to the growth of the emerging insect protein industry as we research and develop innovative technology to optimize black soldier fly production processes that are both economically and environmentally sustainable at the commercial level.
