Abstract:

In this study, one cycle- and multi-cycle culture systems for Artemia in seasonal salt ponds are compared. In one cycle-systems, Artemia is inoculated only once per season, while in multi-cycle systems ponds are drained and re stocked several times per season. In Vietnam, three cycle-systems gave significantly higher cyst yields than did the one cycle-system. However, after two cycles, systems were not significantly different. Food limitation probably caused the steady decline in cyst yields, as observed in the one cycle ponds. In these ponds, females have smaller broods (from the second cycle onwards) and during the last cycle the number of adult females is lower than in multi cycle ponds.
