鱼菜共生系统中种养密度和投喂频率对大口黑鲈生长及水质的影响
Effect of Aquapnics Cultrue Mode on Growth of Micropterus salmoides and Water Quality
摘要
Abstract
To explore the impact of different planting densities,stocking densities and feeding frequencies on performance of Micropterus salmoides and water quality in fish-vegetable symbiosis,the plant densities were set at 32(a1),46(a2),60 plants·m-2(a3),the stocking densities were set at 8(b1),13(b2),18 kg·m-3(b3),the feeding frequency were set at 1(c1),2(c2),3 times·d-1(c3),respectively.The optimal combination of stocking density and feeding frequency were screened through the combined treatment of 3 factors and 3 levels.The results showed that planting density had significant effect on weight gain,weight gain rate,specific growth rate and feed coefficient;feeding frequency had significant effect on weight gain,feeding frequency had significant effect on the crude protein and crude fat content in muscle.The contents of ammonia nitrogen,nitrite nitrogen,total nitrogen and total phosphorus in each treatment group increased significantly over time,peaking on the 7th day.The ammonia nitrogen,nitrite nitrogen and total nitrogen were stable after 37 d,while the total phosphorus stabilized after 25 d.The water quality indexes of a2b1c2 and a2b2c3 treatments were better than those of the other treatments.In this aquaponics system,the lettuce planting density of 6 plants·m-2,the largemouth bass stocking density of 13 kg·m-3 and the feeding frequency of 3 times·d-1 could yield the optimal performance in terms of growth and muscle quality of largemouth bass,and water quality regulation effect.Above results provided a theoretical reference for the planting and stocking in aquaponics system.关键词
