Methods for rearing larval decapod crustacea
© Biologischen Anstalt Helgoland 1970
1. The main methods which have been used for obtaining and rearing decapod larvae are reviewed. These methods range from very simple ones involving little or no control over the environmental conditions, to quite complex techniques with control over such factors as temperature, salinity, and light.
2. The difficulties encountered in rearing decapod larvae are largely the same as those met with in rearing any other planktonic organisms. Although failure to provide suitable food is probably the most important single factor responsible for the failure of many attempts in the past, other features of the rearing conditions may also be critical. In this context the effects of temperature, salinity, light and water type on larval development are briefly discussed.
3. No single rearing technique is suitable for all species and all situations. The choice of technique in any particular case will, therefore, depend largely on the aim in view, whether it be taxonomic, physiological, behavioural or commercial.
