Effects of Aquaponics Culture mode on the Water Quality and Growth Performance of Cyprinus carpiovar
Taking Cyprinus carpiovar as the breeding object,three kinds of hydroponic vegetables,such as water spinach,cress and lettuce,were selected as culture objects,and the cultivation density was set respectively,with 3 parallel treatment and 100 fish per parallel.The culture cycle was 28 days.The contents of total nitrogen and total phosphorus in the water were monitored during the breeding process.After the experiment,the growth index,the removal rate of total nitrogen and total phosphorus and the utilization rate of nitrogen and phosphorus were measured.According to the water quality,growth index and breeding cost,the most suitable vegetable for water culture was water spinach,and the most suitable planting density was 60 plants/m2.
