Remarks | Passive feeder, consume what is available. Daily zooplankton consumption 1.18-2.77% of body weight (Ref. 2875), 1.093 g zooplankton to reach 96 g growth in 2 years, 8.8% weight zooplankton absorbed, 11.4 g zooplankton to get 1 g fish, conversion efficiency of 44.8%. Feeding adaptation other than zooplanktivory, due to absence of food in non-flooded zones. Flooded zones provide cover and offer various food source. Young fish stay in dense shoals in small inlets along with Micralestes acutidens from October until early April (Ref. 3648). |
