DOI: 10.1134/S1067413610040132 The intensive use of brine shrimps in aquaculture supplemented with hydrogen peroxide at concentra imposes some requirements on shrimp cysts. The key tions of 12, 15, 18, 21, and 24 mg/l. In the second requirement is a high hatchability, which reflects the series of experiments, cysts hydrated in 3% NaCl were number of viable embryos. Hatchability is estimated frozen at –18°C, then thawed, washed in fresh water, by several generally accepted parameters (Sorgeloos and incubated in the same media as in the first series. et al., 1986). All these parameters are easy to measure Approximately 4 g
