在实验条件下温度对3种不同规格魁蚶幼贝生长和存活的影响
Effects of temperature on the growth and survival of three different specifications of Scapharca broughtonii under ex-perimental conditions
摘要
Abstract
Within the indoor temperature range from 6 to 24℃ ℃ and by 3℃ gradient, shell length, body mass daily growth and survival are regarded as observed indicators. The text study the effects of different temperature for dif-ferent specifications chief cockle on the growth and survival of the larvae and suitable, appropriate and optimum growth temperature of three sizes of Scapharca broughtonii seedlings(small size shell length 6.565 mm±0.225 mm,body mass 53.704 mg±5.830 mg; medium size shell length 10.114 mm±0.446 mm, body mass 181.918 mg±24.797 mg;large size shell length 14.725 mm±0.315mm, body mass 562.416 mg±42.791 mg). The result shows that three kinds of seedlings could grow form 6 to 24℃ in seawater, but in the water temperature 6 and 24 centigrade, the shell length and body mass daily growth rate of three kinds of specifications is lower. Under the water temperature of 9, ℃the survival rate of three seedlings is the highest, when the water temperature is 24, ℃ the survival rate of the larvae of different specifications is the lowest; In the water temperature 6~21 enviro℃ nment, the survival rate increases with the specifications increased, and it is lower with the specifications increased in 24℃. The suitable temperature for the growth of small, medium and large-sized larvae is 10.7~22.3℃, 6.9~23.2℃ , 3.7~23.3℃, respectively. The more appropriate growth temperature of small, medium and large-sized seedlings is 14.3~19.5℃, 15.8~21.6℃, 11.5~21.0, respectively. ℃ The optimum growth temperature of small and medium size seedlings is 18 , ℃ the tem-perature of the large size of the seedlings is 15℃. Conclusion, with the increase of the specifications, the suitable growth temperature range of the larvae is prolonged and the optimum growth temperature is reduced, the study de-termined the ark-shell larvae suitable growth temperature, provide theoretical support to carry out arkshell interme-diate cultivation and bottom sowing proliferation more effectively.关键词
