1. Various designs and techniques of closed system rearing of fish larvae are being developed using specific species chosen on the basis of their reproductive habits, ecological preference, and potential as environmental indicators.
2. The influence of the parameters of temperature, salinity, food, light, circulation, and the presence of autotropic organisms are tested using as criteria for the success of hatch and development.
3. To date, the results have produced several techniques which increase the percentage of success in raising fry and juvenile fishes.
