大黄鱼仿生态大围塘养殖技术初探

The Preliminary Study on Simulated Ecological Large Pond Culture of Larimichthys crocea

摘要: 本试验利用自然条件进行仿生态大围塘养殖，试验围塘面积30 hm²，水位28~35 m，对照网箱为紧邻试验围塘的6口3.8 m × 3.8 m × 3.5 m网箱，面积为86.64 m²。结果表明：大围塘仿生态养殖的大黄鱼体长/体高平均值为3.93，体质量/体长平均值为16.22；网箱养殖的大黄鱼体长/体高平均值为2.80，体质量/体长平均值为14.73，表明仿生大围塘养殖的大黄鱼比网箱养殖的大黄鱼体型长、密实度高，仿生态大围塘养殖的大黄鱼体色较网箱养殖的大黄鱼体色金黄、鲜艳，仿生态大围塘养殖能提高大黄鱼品质。

Abstract: Simulated ecological aquaculture of Larimichthys crocea was carried out by utilizing the natural conditions in this study. The experimental large pond was 30 hm² and the water height was 28 - 35 m. There were 6 control cages which were settled closed to the experimental pond. The size of every cage was 3.8 m × 3.8 m × 3.5 m, and the total area was 86.63 m². The results showed that the aver-age body length/average body height (BL/BH) and the average body weight/average body length (BW/BL) were 3.93 and 16.22 respectively for simulated ecological pond culture, but 2.80 and 14.73 for cage culture, which showed significant difference. The results showed that the body shape and firmness of Larimichthys crocea by simulated ecological faring were more better than that of cage farming. The body color of Larimichthys crocea was more yellow and shining than cage fish. In conclusion, imitating ecological farming could improve the quality of Larimichthys crocea.
