Abstract

Populations of Paranephrops planifrons and P. zealandicus were reared in aquaria and their growth rates monitored. When reared in unheated aquaria (10–21°c) P. planifrons grew to 20 mm orbit‐carapace length in 12–18 months and P. zealandicus reached the same size in 9–10 months. This is faster, for both species, than in feral populations. When reared in an aquarium at 18–21°C however, P. planifrons could be grown to 35 mm orbit‐carapace length in 18 months. Mortality in both species was very high (60–93%).
