Lavens, P.; Baert, P.; De Meulemeester, A.; Van Ballaer, E.; Sorgeloos, P. (1985). New developments in the high density flow-through culturing of brine shrimp Artemia. J. World Aquacult. Soc. 16: 498-507

A closed culture system for the high density culturing of Artemia spp. in 300-liter tanks using a new formula of artificial seawater and micronized waste products from agricultural crops as food is described. Culture conditions are greatly improved by applying a new filter technique and an electronic transparency meter which controls food distributions automatically. A total volume of 6,000 liters of culture water recirculated over a rotating biological contactor, a cross-flow sieve and a plate separator at a flow rate of 3000 liters per hour. Production yields obtained with this culture system, when extrapolated to a 1 m³ tank, indicate that 50 g of brine shrimp cysts can be converted into 20 kg of fresh (wet dry) pre-adult Artemia in 14 days. These results are comparable to those reported earlier with open flow- through conditions.
