Aquaculture Techniques:Water Use and Discharge Quality,

摘要

The objectives were to develop and test methods of predicting waste product generation from aquaculture facilities. Factors chosen for testing were (1) feeding rate; (2) diet efficiency; (3) growth rate; (4) population density; (5) water replacement time; (6) oxygen consumption; (7) fish size;and (8) water temperature. Significant results are: (1) The identification of factors not only involved with the generation of waste products from an aquaculture facility,but also having the potential of affecting the production of an aquaculture facility; (2) The development of a practical method for determining oxygen consumption of fish in varying controlled environmental conditions; (3) The development of a computerized program for fish growth in optimized loading conditions of population density and water replacement time; (4) The development of a method to predict more accurately the anticipated growth rate of a group of fish; (5) The development of a method to predict the solids,both settleable and suspended,produced daily by a group of fish being held in known conditions.
