at this stage (Stage 1) the tiny fish, just 10mm long are kept in tubs along with their siblings, aerated seawater and fed a diet that is constantly being modified as ongoing research determines the most effective to promote healthy growth...


at stage 4, after several moults, the lobsters have to be kept separated as by now they are capable of determining in which direction they can swim - and lobsters are most definitely cannibalistic - given the chance eventually there would only be one very well fed lobster left in the tank if left to their own devices...



once stage 5 has been reached the lobsters are now said to be truly benthic and able to survive in close proximity to the bottom of the sea where they able to protect themselves by burying in the sand...
