Unit 10 - Race way culture
Race way system
Advantages and disadvantages of this system
Raceway culture has been traditionally practised for hatchery production of fish, because for decades and there are several good reasons for this. Environmental parameters (i.e., water quality, temperature etc., and water quantity are easier to manage in raceways than in pond systems. Flowing water flushes wastes from the culture units. Flowing water also forces the fishes to exercise. Studies have shown that exercised fish have better survival rates when stocked into the Wild (Wheaton 1977). The shallow water in raceways allows visual observation of the fish so that diet and /or disease problems can be promptly corrected. Finally feeding and harvesting are generally easier in raceway systems. Feeding and disease treatment are more easily managed in raceway systems than in open systems or ponds. On the negative side fish are normally cultured in very high densities in raceway, leading to increased risk of diseases due to the stress caused by confinement and crowding. Better management skills are required for raceway culture. Feed may be more due to waste/passes through the water.
