Culture of marine species

A marine polyculture system for the rearing of marine species, the system comprising:

• (a) maintaining a flow of salt water through a finfish culture stage to provide a water turnover rate in that stage greater than the generation time of common planktonic species, and supplying finfish feed to the stage for the culture of finfish;
• (b) maintaining a flow of finfish culture stage effluent through a crustacean culture stage and supplying plankton nutrients to the stage to develop plankton blooms in that stage for the culture of crustacean species in that stage;
• and
• (c) maintaining a flow of effluent from the crustacean culture stage through a filter feeder culture stage for the culture of filter feeders therein.

A method of utilizing nutrient poor ocean waters for the culture of marine species, which comprises:

• (a) maintaining a flow of nutrient poor ocean water through a finfish culture stage at a rate to inhibit the development of common planktonic species in that stage;
• (b) supplying finfish feed to the finfish culture stage for the culture of finfish therein;
• (c) maintaining a flow of finfish culture stage effluent through a shrimp culture stage;
• (d) supplying plankton nutrients to the shrimp culture stage for the culture of plankton in that stage to constitute shrimp feed for the culture of shrimp in that stage;
• (e) maintaining a flow of shrimp culture stage effluent through a filter feeder culture stage for the culture of filter feeders in that stage;
• and
• (f) feeding filter feeder stage effluent to a seaweed culture stage for the culture of seaweed and for the removal of waste products from the effluent, and discharging effluent from that stage.
