Since tilapia have limited access to natural foods in tanks, they must be fed a complete diet containing vitamins and minerals. Tank culture also has some disadvantages. Intensive tank culture can produce very high yields on small parcels of land. Small tank volumes make it practical and economical to treat diseases with therapeutic chemicals dissolved in the culture water. ![]() With tanks, feeding and harvesting operations require much less time and labour compared to ponds. Tanks allow the fish culturist to easily manage stocks and to exert a relatively high degree of environmental control over parameters (eg, water temperature, DO, pH, waste) that can be adjusted for maximum production. In ponds, mixed sex populations breed so much that parents and offspring compete for food and become stunted.
