Resumé

The effect of stocking density of the calanoid copepod Acartia tonsa was evaluated in a 96 h rearing experiment. Possible density-dependent egg production and egg viability were analysed at stocking densities of 100, 200, 300, 400 and 600 adults L−1. Temperature, oxygen saturation and algal concentration were kept optimal. A non-density-dependent mortality rate of 15–19% day−1 was documented. A non-significant density-dependent egg production was observed between 100 and 600 adults L−1. The average egg production was 22.5±8.8 egg female−1 day−1 in all densities. The average egg hatching success was 84.7±4.8% and was never observed below 76.1%, with no significant differences across the stocking densities. Conclusively, as a practical recommendation for the aquaculture industry, copepod cultures with densities ranging from 100 to 600 adults L−1 and presumably even more dense cultures are possible with the studied species obtaining a steady egg production and still high egg viability.
