Abstract: Influence of salinity on growth, development and survival of \%Asplanchna brightwelli\% was studied outdoors at water temperature of 25℃ at salinity gradient of 0,1,2 and 3. The results indicated that intrinsic growth rate of increase(rm), finite incremental rate, net rate of proliferation, reproductive times and total reproductive quantity all peaked at salinity of 2, which was 1.6658, 5.2899, 20.1, 4 9 and 23 2, respectively. At this salinity level it also possessed the longest life span, on average, reaching 98 4 days but the shortest developmental stage of pre-reproduction descending to 18 71 days. At salinity of 3 its lifetime was the shortest, namely 1 4414 days. Salinity of 2 is considered to be the optimal for existence of \%Asplanchna brightwelli\%.
