Embodiment Construction
[0123] Below in conjunction with accompanying drawing and embodiment the present invention is further described:
[0124] A method for establishing a dynamic feeding table for long-nose catfish culture, the steps are as follows:
[0125] 1. Conditions of Growth Experiment
[0126] 1.1 The effect of feeding level on feeding, growth and energy budget
[0127] To study the effects of different feeding levels on the feeding, feed utilization and energy budget of Long-snorted Catfish. Five groups of feeding levels were designed in the experiment, namely: starvation, 0.8, 1.6, 2.4% of initial body weight / day and fed groups, and each feeding level had three repetitions. The experiment was carried out in a recirculating aquaculture system consisting of 15 fish tanks (water volume 120 liters). The dissolved oxygen in the water was higher than 7.5 mg / L, the water temperature was maintained at about 29±2°C, the pH value was 7.7-8.0, and the ammonia nitrogen concentration was lower than...
