摘要
为充分利用黄河三角洲资源优势,提高池塘利用率,根据膨腹海马(Hippocampus abdominalis)、线纹海马(Hippocampus erectus)的不同生活习性,在黄河三角洲沿海池塘开展室内、外接力养殖。冬、春季气温较低时,在室内养殖;3月初,室外池塘水温达到18℃,把膨腹海马移至室外池塘养殖;5月上旬,室外池塘水温稳定在20℃以上,选择晴天投放南美白对虾(Litopenaeus vannamei)苗;5月中下旬,室外池塘水温升至22℃,把膨腹海马移回车间内继续室内养殖,室外池塘接力投放耐高温品种线纹海马与南美白对虾混养;10月份,对虾用地笼进行收获,两种海马平均体长分别达5.1 cm、10.3 cm。
In order to make full use of the resource advantages of the Yellow River Delta,improve the utilization rate of ponds,according to the different living habits of Hippocampus abdominalis and Hippocampus erectus,indoor-outdoor relay breeding was carried out in the coastal ponds of the Yellow River Delta.When the temperature was low in winter and spring,indoor culture was carried out;at the beginning of March,when the water temperature in the outdoor pond achieved 18℃,the Hippocampus abdominalis was moved to the outdoor pond for breeding.In early May,the water temperature in the outdoor pond was stable above 20℃,the Litopenaeus vannamei were stocked on sunny day.In the middle and late May,the water temperature in the outdoor pond rose to 22℃,the Hippocampus abdominalis was moved back to the workshop to continue indoor culture,the high-temperature resistance species Hippocampus erectus were put into the outdoor pond for polyculture with Litopenaeus vannamei.In October,Litopenaeus vannamei were harvested with cage-like fish trap,the average body length of the two seahorses was 5.1cm and 10.3 cm respectively.
