Planning the number of fingerlings to be stocked into a grow-out system, whether it is a pond, reservoir or cage, is based on several factors, including: the average size of the fish harvest that is needed; the ability of the rearing system to maintain good water quality; the potential of the broodstock to produce fingerlings; demands of the market for fish; and the expected survival rate of the fingerlings produced at the time of stocking.
Fish Growth and Feed
Choosing the appropriate feed for the fish to be grown, the amount to be fed and environmental considerations are all crucial factors in planning the system’s feeding regime. Considerable food and money can be saved by correctly controlling the feeding system to maintain it at an optimal level for fish growth. Cutting-edge electronic equipment allows greater precision in the amount of feed used, which in turn saves costs while fostering optimal fish growth.
From the extensive experience gathered by the A.R. staff, it is clear that fish quality and its shelf life significantly affected throughout the cultivation process, but especially during harvest and transportation to market. Therefore, the facilities and equipment used for this purpose should be carefully prepared in advance. Stress damages fish quality and harvesting conditions should minimize it for best results.
