Improved Stocks and Management Practices for Commercial Tilapia Culture in Hawaii and the Pacific Region—Hawaii Component, Year 2
University of Hawaii Sea Grant College Program
- To complete the first growth comparison trials, begun in Year 1 of the Hawaii component with extension to approximately 400 g final fish size. The original objective was stated: “To obtain at least three existing commercial tilapia stocks from within the state (one each from Oahu, Hawaii, and Maui islands), and to perform the first growth comparison trial between in-state and imported stocks (both species if permits are granted). Also, to send fingerling O. aureus to Oahu for comparison trials there. Deliverable: Description of trial, photos of fish, written results and interpretation. Accomplishment stated and photos reproduced for project reports, workshops, newsletters, etc.”
- To obtain at least two additional in-state stocks and to perform further experimental comparisons of growth potential.
- To distribute fingerlings of imported O. aureus stocks (O. niloticus is not permitted for distribution from the farm) to interested businesses for on-site testing, under terms to be established with community input, avoiding interference with markets. This item may begin late in Year 1 if sufficient fish are available after allocation to growth trials.
- To integrate the work on importation, quarantine, growth comparisons and stock maintenance protocols into a manual on best management practices, and to offer public workshops covering this information during the last half of the project.
