Summary: | Atlantic cod (Gadus morhua) is an important source of income for the fishermen and processors in Maritimes and Newfoundland. Depletion of cod stocks, particularly in the Grand Banks, has prompted the Federal Government to introduce a two-year moratorium in certain areas. Sea Forest Plantation has initiated a cod-farming operation in several locations in Newfoundland. Undersized cod from inshore trap fishery during June-August are transported to holding pens by boat. They are then fed intensively on live or frozen capelin or on pelleted feed formulations. The intensively fed cod generally grow at a much faster rate than wild cod. The high growth rates obtainable in holding pens are due to higher temperature in the shallow waters and the feeding regimes. Although cod may be relatively easily bred and grown to a marketable size in approximately two years, the high cost of raising fish up to approximately 500 g size makes the operation uneconomical at current prices. Harvesting of farmed cod generally begins in December and may continue until January-February. They may be sold as prime fish fillets in the U.S. and Canadian markets or could be frozen in special custom-designed packages. The present paper reports on changes in the chemical composition and characteristics of pen-held cod over a 20-week period during intensive feeding. |
