摘要: 运用定量投喂的方法研究不同性状饵料对波纹龙虾(Panulirushomarus)生长性能的影响差异性。试验选用一批规格相近、体长 9.10~9.84cm、体重50.30~62.25g的波纹龙虾苗600只,分为2组,A组投喂半熟化贝肉,B组投喂新鲜贝类,在室内水泥池进行120 d的生长试验,每15天通过对不同组随机抽取的50只波纹龙虾进行特定生长率、体长增长率、体重增长率、饵料转化率及存活率等参数差异性的分析,优选养殖波纹龙虾的最佳饵料。结果表明:A组和B组的特定生长率分别为(0.86±0.04)% 和(0.87±0.06),两者差异不显著;A组和B组的体长增长率和体重增长率分别为(49.13±0.63)%、(179.23±0.84)%和(55.58±0.71)%、(185.10±0.91)%,两者差异不显著;A组和B组的饵料转化率分别为(130.55±0.45)%和(1333.32±0.52)%,差异极显著(P<0.01),A、B比为1∶10.21;A组的存活率高于B组,分别为95.67%和90.33%,差异显著(P<0.05);A组饵料成本低于B组,分别为990.64元和1147.59元,差异显著(P<0.05)。因此,综合考虑饵料获得的难易程度、龙虾存活率高低、养殖成本大小等因素,投喂半熟化贝肉能提高波纹龙虾的养殖效果。

Abstract: The quantitative feeding method was used to study the influence difference of the bait with different characters on the growth performance of Panulirushomarus. 600 similar specifications of the same group of Panulirushomarus with body length of 9.10~9.84 cm and body weight of 50.30~62.25 g were randomly divided into two groups. Group A was fed with semi-cooked shellfish, and group B was fed with fresh shellfish. The growth test was conducted in an indoor cement pond for 120 days. Every 15 days, 50 lobsters were randomly selected from different groups to analyze the difference of specific growth rate, body length growth rate, body weight growth rate, bait conversion rate and survival rate, so as to select the best bait for culture of lobsters. The results showed that the specific growth rates of group A and group B were (0.86±0.04) % and (0.87±0.06) %, respectively, and there was no significant difference between them. The increase rate of body length in group A and group B were (49.13±0.63) % and (179.23±0.84) %, respectively. The increase rate of body weight in group A and group B were (55.58±0.71) % and (185.10±0.91) % respectively.The feed conversion rates of group A and group B were (130.55±0.45) % and (1333.32±0.52) %, respectively, and the difference was extremely significant (P<0.01). The ratio of A to B was 1∶10.21. The survival rate of group A was significantly higher than that of group B (95.67% and 90.33%, respectively) (P<0.05). The feed cost of group A was significantly lower than that of group B, which were 990.64 yuan and 1 147.59 yuan, respectively (P<0.05). Therefore, while factors such as the difficulty of obtaining bait, the survival rate of lobsters and the breeding cost were taken into consideration comprehensively, feeding semi-cooked shellfish could improve the breeding effect.
