| 摘 要： | 为了探明虎斑乌贼喷墨卵对孵化及胚胎发育的影响,采用单因子实验研究了喷墨卵与正常卵的孵化率、培育周期、孵化周期、初孵幼体体质量,并比较了剥膜喷墨卵、剥膜正常卵、喷墨卵、正常卵4种类型卵的幼体生长和存活率。结果显示,虎斑乌贼喷墨卵和正常卵的孵化率无显著差异,喷墨卵的孵化率为90.1%±1.5%,正常卵的孵化率为87.9%±0.7%;两种卵的初孵幼体体质量也无显著差异,喷墨卵的初孵幼体体质量为(0.18±0.01)g,正常卵的初孵幼体体质量为(0.17±0.01)g;两种卵的培育周期、孵化周期均无显著差异,喷墨卵的培育周期为(34.67±0.89)d,孵化周期为(14.33±0.44)d,而正常卵的培育周期为(35.33±0.44)d,孵化周期为(14.67±0.67)d。而剥膜喷墨卵、剥膜正常卵、喷墨卵、正常卵4种类型卵的幼体存活率差异显著,剥膜喷墨卵和剥膜正常卵的存活率明显小于喷墨卵和正常卵,而剥膜喷墨卵和剥膜正常卵之间、喷墨卵和正常卵之间的存活率无显著差异;4种类型的幼体日均增长量和增重量差异显著,剥膜喷墨卵和剥膜正常卵的幼体日均增长量和增重量明显小于喷墨卵和正常卵,而剥膜喷墨卵和剥膜正常卵之间、喷墨卵和正常卵之间的幼体日均增长量和增重量无显著差异。

| Abstract: | In order to explore the effects of inkjetting and stripping on hatching and larval growth of fertilized eggs of Sepia pharaonis, inkjetting and normal eggs hatching rate, incubation periods, hatching periods, and the weight of hatchling cuttlefish were compared by single factor experiment, and comparisons of survival rate and larval growth of four kinds of eggs (inkjetting and peeled eggs, normal and unpeeled eggs, inkjetting and unpeeled eggs, normal and peeled eggs) were also performed. The results showed:the hatching rates of inkjetting eggs and normal eggs of S. pharaonis showed no significant differences, and the hatching rates of inkjetting eggs and normal eggs was 90.1%±1.5% and 87.9%±0.7%, respectively. The statistical analyses of weights of hatchling cuttlefish between inkjetting eggs and normal eggs of S. pharaonis also showed no significant difference, and the mean weight of hatchling cuttlefish of inkjetting eggs and normal eggs were (0.18±0.01) g and (0.17±0.01) g, respectively. Both the incubation periods (d) and the hatching periods(d) between inkjetting eggs and normal eggs of S. pharaonis showed no significant difference, and the incubation periods (d) of inkjeting eggs and normal eggs were (34.67±0.89) d and (35.33±0.44) d, respectively, meanwhile the hatching periods(d) of inkjetting eggs and normal eggs were (14.33±0.44) d and (14.67±0.67) d, respectively. The survival rates of four kinds of eggs showed significant difference, and the survival rates of peeled inkjetting eggs and peeled normal eggs were obviously lower than those of the unpeeled inkjetting eggs and unpeeled normal eggs. However, the survival rates of cuttlefish between peeled inkjetting eggs and peeled normal eggs, unpeeled inkjetting eggs and unpeeled normal eggs all showed no significant difference. The diurnal growth rates of cuttlefish and the average diurnal gain weight of cuttlefish among four kinds of eggs showed significant difference. The diurnal growth rates of cuttlefish and the average diurnal gain weight of cuttlefish of peeled inkjetting eggs and peeled normal eggs were obviously lower than those of unpeeled inkjetting eggs and unpeeled normal eggs. But the diurnal growth rates of cuttlefish and the average diurnal gain weight of cuttlefish between peeled inkjetting eggs and peeled normal eggs, and between unpeeled inkjetting eggs and unpeeled normal eggs showed no significant difference. |
