These isopods were fed with plaice (Pleuronectes platessa) from the North Sea. Growth in captivity was very slow. For the first growth phase before reaching sexual maturity of females the value K = 0.12 was calculated for the Bertalanffy growth constant. Mature males are markedly smaller than breeding females (average lengths: 16.0 and 22.5 mm). An age of more than 5 years was calculated for an average-sized male, females spawn at an age of more than 10 years. No evidence for protandric hermaphroditism could be found.
