Study on feeding habits of Piaractus mesopotamicus (Pacu) larvae in fish ponds

A limnological study of the artificial fish pond and an analysis of the stomach contents of pacu (Piaractus mesopotamicus) larvae of 2 to 45 days age were made for a period of 45 days to evaluate their feeding preferences. A preference for chlorophytes and rotifers were noted, while other planktonic species remained constant in the stomach contents. Some limnological variables were found to have strong influence on the feeding behavior of the pacu. A preference for feeding on smaller species in the first few days of larval development was also noted
