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-2a3) , the stocking densities were set at 8 (b1),13 (b2),18 kg·m-3b3), the feeding frequency were set at 1 (c1) ,2(c2) ,3 times·d-1c3) ,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.

摘要:

为研究不同种植密度、养殖密度和投喂频率对鱼菜共生系统中大口黑鲈生长、肌肉营养成分及水质的影响,设置生菜种植密度分别为32(a1)、46(a2)、60株·m-2a3),大口黑鲈养殖密度分别为8(b1)、13(b2)、18kg·m-3b3),投喂频率为1(c1)、2(c2)、3次·d-1c3),通过3因素3水平的组合处理筛选种养密度及投喂频率的最优组合。结果表明,种植密度对增重量、增重率、特定生长率和饲料系数均影响显著;投喂频率对增重量影响显著;投喂频率对肌肉中粗蛋白、粗脂肪含量影响显著。各处理的氨氮、亚硝酸盐氮、总氮和总磷含量均显著升高,第7天时达到高峰;氨氮、亚硝酸盐氮、总氮在第37天以后呈稳定状态,总磷在第25天以后呈稳定状态,a2b1c2a2b2c3处理的水质指标较优。在此鱼菜共生系统中,生菜的种植密度为46株·m-2、大口黑鲈养殖密度为13 kg·m-3、投喂频率为3 次·d-1时,大口黑鲈生长和肌肉品质较好,且具有较好的水质调控作用。研究结果为鱼菜共生系统的种养管理提供理论参考。
