Problem: Marine breeding centers breed baby fish — fingerlings — in seawater pools and, like seeds, sell them to farmers who raise them and sell them in turn to their clients (fish markets). The marine breeding centers commonly pump water from the sea, use it for fish breeding purposes and then return the water back into the surf. This pumping happens on average five times a day, with a 500 percent daily water exchange rate.
Solution:Now, an Israeli company is trying to revamp that growing process.Latimeria’s Aquaculture System uses unique Recirculating system combined withartificial seawater to upend fish breeding.
Goals and Objectives:The solution is aiming to change all of this by avoiding the use of seawater, it recirculates the water between the fish tank and a set of mechanical and biological filters to keep it clean.
Implementation:Latimeria, an Israeli startup, desalinates drinking or agricultural water — using off-the-shelf desalinating technology — and then adds regular marine salt to re-salinate the liquid, to create cheaper, healthier, environmentally safer way to raise fingerlings. This water is then placed in special polypropylene tanks called “water rings,” in which the fingerlings are bred and raised.
The new system enables breeders to grow their fingerlings in salt water at any location, away from the sea, and helps better control the growth environment by minimizing the risk of introducing pathogens and the total consumption of energy and water. The water rings are modular and independent from central systems, so they allow the easy scaling up of operations.
Achievements: Latimeria's breeding center uses twice as less energy compared to a traditional breeding center. The working procedures are very much like the other breeding centers, yet maintaining a very high biosecurity level. Breeders using the system would need to produce just around 3 million fingerlings a year compared to somewhere around 6 million at a regular marine breeding center.
