Increasing the Efficiency of Yellow Perch Fingerling Production by Optimizing Pond Trophic Dynamics and Feed-Training Strategies
The overall goal of this project is to gain a better understanding of the food chain dynamics and feed-training methods used in the yellow perch aquaculture industry. The growth of the yellow perch aquaculture industry is constrained by the high cost of feed-trained fingerlings. Using eight ponds at two locations, the project will manipulate species-specific pond food chain dynamics and feed-training aquaculture methods. The project will use selected fertilizer regimes to identify and quantify plankton and benthic communities in pond culture systems, examine larval and post-larval prey selection and prey availability, and compare photo-periods, temperatures, and dietary regimes during the weaning period. At harvest, fish survival and net fish yield for each pond will be measured. The use of krill and a moist diet as transitional feeds to a conventional dry diet will also be evaluated.
