To understand optimized conditions for rotifer cultivation,the effects of low salinity on the proliferation and egg-laying rate of the rotifer Brachionus plicatilis were investigated.Different sa-linity treatment groups(3‰,4‰,5‰,6‰)were set up under controlled water temperature and p H conditions,with daily feeding of Chlorella and monitoring of rotifer proliferation.The results showed that both the proliferation rate and egg-laying rate of the rotifers increased significantly with the in-crease in salinity,with the highest proliferation rate observed in the 6‰ salinity group.This indicates that while Brachionus plicatilis can survive at low salinities,its reproductive performance is better at higher salinities.
