Comparison among inkjetting eggs and normal eggs of Sepia pharaonis
摘要
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 ofS.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 ofS.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.关键词
