Abstract:
A system for the experimental larval rearing of
phyllosoma of southern rock lobster (Jasus edwardsii) is described.
Sea water filtered to 1 µm, heated to 18°C and disinfected with
ultraviolet light, passes into circular 35-l vessels via a series of jets to
achieve constant circular flow. Water exits through a screened drain fitted
to the wall of the vessel and positioned to maintain a volume of 10 l with a
turnover of 3-4 times/h. Phyllosoma were cultured in this system from hatch
to Stage XI when fed ongrown Artemia and pieces of mussel (Mytilus
edulis). The system may readily and cheaply be replicated for
experimental comparisons of several treatments.
