Food consumption was measured as the quantity of food intakeper shrimp per hour (g/shrimp/h) and measured according to the methods described by Soares et al. (2005). Thus, over three successive days, food remains were collected 3 h after feeding through the siphoning of each tank. The samples were dried to constant weight (60 °C) and weighed. Previously, the dried weight of the foods for each dietary treatment was measured by drying at 60 °C, and the proportional difference between food weight before and after drying were recorded. The amount of food lost due to dissolution in seawater
was also estimated for each dietary treatment using three tanks without shrimps, which received the same foods as the tanks with the shrimps. Similar to the shrimp tanks, 3 h after adding food, the food remains were collected from the empty tanks, dried and weighed. The food consumption (FC) for each dietary treatment was calculated by the equation:
