摘　　要：为探究温度对盐蚕豆虫(Fabrea salina)生长的影响,基于Montagnes种群模型进一步探讨了15℃、25℃、35℃温度条件下,盐蚕豆虫摄食杜氏盐藻(Dunaliella salina)、等鞭金藻(Isochrysis galbana)、普通小球藻(Chlorella vulgaris)和牟式角毛藻(Chaetoceros muelleri)的种群动态变化。结果表明:Montagnes模型适用于评估不同温度对盐蚕豆虫种群动态的影响;盐蚕豆虫的最大摄食率(I max)总体上呈现随温度升高而增大的趋势,35℃时投喂普通小球藻盐蚕豆虫的I max为最大值5.832×10^(4)ind./h,15℃时杜氏盐藻组的I max为最小值9.150×10^(2)ind./h;4种饵料投喂下盐蚕豆虫的最大出生率(B max)总体上随温度的升高逐渐增大,35℃时投喂等鞭金藻组的B max为最大值1.7641/d,15℃时投喂普通小球藻的盐蚕豆虫的B max为负,表明15℃时会限制盐蚕豆虫的生长和摄食等活动,35℃时会促进盐蚕豆虫的摄食和生长;盐蚕豆虫摄食杜氏盐藻时在35℃时的转换效率最高,且在饱和饵料浓度下的最小死亡率(D min)也最大。研究表明,25℃时杜氏盐藻组的转换效率(e)相对其他3种被捕食者较高,最小死亡率(D min)最小,可作为大规模高密度培养盐蚕豆虫的条件;盐蚕豆虫对温度耐受范围相对较高,可以成为优良的饵料生物。To explore the effect of temperature on the population dynamics of Fabrea salina,the Montagnes population model was used to study the population dynamics of F.salina feeding different diets,such as Dunaliella salina,Isochrysisgalbana galbana,Chlorella vulgaris and Chaetocerosmuelleri under the different temperatures of 15℃,25℃,35℃.The result shows that the Montagnes model is suitable for evaluating the effects of the different temperatures on population dynamics of F.salina.The maximum feeding rate(I max)of F.salina generally increases with increasing temperature.The peak(I max)of F.salina feeding on C.vulgaris is 5.832×10^(4) ind./h at 35℃.For D.salina,the(I max)drops to a minimum of 9.150×10^(2) ind./h at 15℃.The maximum birth rate(B max)of F.salina under the four diets generally increases with increasing temperature.The maximum B max of F.salina feeding on I.galbana is 1.7641/d at 35℃,while the maximum(B max)of F.salina fed C.vulgaris is negative at 15℃.The analysis indicates that 15℃limits the growth and feeding activities of F.salina,while 35℃promotes its feeding and population growth rate.Its highest conversion efficiency and highest minimum mortality(D min)were observed at 35℃,as was the saturated feed concentration of the prey D.salina.At 25℃,the conversion efficiency(e)of D.salina diet was relatively high compared with the other three diets,and the minimum mortality rate(D min)was the smallest,and can be used as the criteria for large-scale,high-density cultures of F.salina.Fabrea salina has a relatively high temperature tolerance range and could be used as an excellent food organism.
