Abstract
The design and operation of a small research scale and a mass commercial scale rearing system for the culture of marine ornamental decapod crustacean larvae are described in the present paper. Preliminary data on the culture of the Mediterranean cleaner shrimp ( Lysmata seticaudata), peppermint shrimp ( Lysmata wurdemanni), blue-white partner shrimp ( Periclimenes sagittifer), sponge crab ( Cryptodromiopsis antillensis) and green emerald crab ( Mithraculus sculptus) are also presented. The use of these “plantonkreisel” based systems allowed the complete larval development of the above-mentioned species, inducing minimal mechanical stress while keeping an excellent water quality. Higher survival rates (up to 70% and 60% for L. seticaudata and L. wurdemanni, respectively) to the post-larval stage and a shorter larval stage duration (27 and 22 days for L. seticaudata and L. wurdemanni, respectively) were achieved, in comparison to conventional rearing systems. This culture technology may play a key role in the realisation of a commercial culture of these highly priced crustacean species and therefore the reduction of wild specimen collection.
