Evaluates project to help the Government of Jamaica increase fish production and establish a system of freshwater fish farms. PES, consisting of a factsheet, covers the period 6/79-3/82 and is based on a special evaluation (PD-AAM-280). Action decisions are to: extend the project to 8/84; revise the financial plan; adjust project outputs to meet more realistic targets; minimize CARP studies unless market analysis indicates a significant demand for them in Jamaica; conduct a market study as a guide to long-range tilapia culture; increase training to help maintain full staffing; develop recordkeeping systems within the Inland Fisheries Unit for production economics; and continue research on sex control of fry by hormone treatment, stocking density vs. growth, and use of hybrids.
