| 摘 要： | 为探索低换水量的对虾养殖生产方式,该研究构建了一种简易式工厂化对虾养殖系统,试验组利用自行研发的蛋白分离器和新型集污盘去除系统总悬浮颗粒物和老化微藻,对照组不设置蛋白分离器和集污盘,进行对虾养殖和水质调控试验,结果表明:试验组平均总氨氮浓度、平均亚硝氮浓度、平均TSS(Total Suspended Solids)浓度、平均副溶血弧菌数量分别为(0.4±0.16)、(0.53±0.23)、(68.33±39.72)mg/L和(140±113.83)cfu/mL,显著低于对照组(0.96±0.62)、(1.17±0.59)、(147.14±94.18)mg/L和(661.34±473.96)cfu/mL(P0.05);试验组成活率及单位产量分别为82.62%±5.64%和(3.44±0.85)kg/m~3,显著高于对照组18.29%±4.63%和(1.09±0.23)kg/m~3(P0.05)。该研究构建的简易式循环水工厂化系统,设置蛋白分离器流量10 m~3/h且不间断运行,养殖前45 d不换水、后55 d利用集污盘进行强排污保持日换水量5%的情况下能够有效调控对虾养殖水质。

| Abstract: | China has been the largest shrimp farming country in the world. As such , shrimp culture has also made a great contribution to the increase of farmers'' income and export earnings. In recent years, the performance of intensive aquaculture system was seriously affected by a large amount of nitrogen that discharged into the aquaculture water body. Normally, a conventional solution to this problem is to drain a lot of water for water exchange in the intensive aquaculture system. In this case, most water resources can be overly consumed to waste in the aquaculture system. Alternatively, the industrial recirculating aquaculture system can be selected due to its good system closure, but the high cost of equipment input and operation have limited its large-scale application in industrial aquaculture of prawn. In this paper, a set of simple industrial shrimp culture system with circulating water was designed to develop a protein separator removal system TSS (total suspended solids) and aged microalgae, where the collection and drainage effect of culture pool were strengthened using the self-developed collection tray. An experiment related to industrial shrimp culture was carried out to control the water quality. The results showed that the average concentration of total ammonia nitrogen was 0.4±0.16 mg/L, significantly lower than the control group (0.96±0.62 mg/L), P<0.05. The average concentration of dissolved oxygen in the control group was 5.39±1.15 mg/L, dramatically lower than that in the test group (6.18±0.68 mg/L), P<0.05. The average concentration of nitrous oxide in the control group was 1.17±0.59 mg/L, significantly higher than that in the test group (P<0.05). The average concentration of TSS in the test group was 68.33±39.72 mg/L, lower than that in the control group (147.14 ± 94.18 mg/L, P<0.05). The average number of Vibrio parahaemolyticus in the experimental group was 140 ± 113.83 CFU/ml, lower than that in the control group (661.34 ± 473.96 CFU/ml), P < 0.05. After the age of 30 days, the body weight of the test and control group were 1.05 ± 0.15 g and 0.98 ± 0.26 g, respectively, whereas, the body length was 4.95 ± 0.56 cm and 4.86 ± 0.69 cm, respectively, indicating that the difference between two groups was not correlated (P > 0.05). After the age of 60 days, the body weight of the test and control group were 5.26±0.82 g and 6.12±1.76 g, respectively, whereas, the body length was 8.17 ± 0.92 cm and 9.12 ± 0.81 cm, respectively, indicating that the difference between two groups was significant correlated (P < 0.05). After the age of 90 days, the body weight of the test and control group were 13.89±1.23 g and 20±1.58 g, respectively, while, the body length was 12.26±1.98 cm and 14.06±1.68 cm, respectively, indicating that the difference between two groups was significant correlated (P<0.05). The shrimp size of the test and control group were 72±2.65 ind/kg and 50±8.19 ind/kg, respectively, showing a significant difference (P<0.05). In terms of survival rate, the shrimp size of the test and control group were 82.62±5.64% and 18.29±4.63%, respectively, with significant difference (P<0.05). The single output of the test and control group were 3.44±0.85 kg/m3 and 1.09±0.23 kg/m3, respectively, indicating a significant difference (P < 0.05). This finding can offer a promising method to accurately monitor the water quality in an intensive aquaculture system for the shrimp farming. |
