中文摘要:
      试验用盐藻、酵母、麸皮三种饵料培养卤虫。结果表明,卤虫生长速度的差异显著(p〈0.05)。其中,麸皮且最好,其次是盐藻组,最差的是酵母组。麸组的卤虫提高8d达到性成熟,其体长分别是盐藻组的1.23倍、酵母组的1.27倍。三种饵料对卤虫成活率的影响差异显著(p〈0.01)。在达到性成熟时成活率最高的为盐藻组,其次为麸皮组,最差的为酵母组,其均值分别为86%、67%、27%。三种饵料对卤虫生殖的影响差异也极显著(p〈0.01),麸皮组的生殖次数、生殖总量和平均每次生殖量均最高,分别为5、320、64;其次是酵母组,分别为1.5、63、42;盐藻组的卤虫在本实验中不生殖。故以麸皮培养卤虫量好,有利于卤虫的生长和种群增殖。
英文摘要:
      The different groups of Artemia sp. were cultured using three diets of Dunaliella salina, Saccharomyces cerevisiae and wheatbran. The results showed a significant difference of growth rate among the groups of Artemia sp. (p<0.05). The group of Artemia sp. fed on wheat bran (group W) was the fastest in growth, While the group fed on Saccharomyces cerevisiae (group S) was the poorest. It was 8 days shorter to reach sexual maturity for the group W than for the others. Besides, The effects of diets on the survival rate was also significantly different (p<0.01). Upon to sexual maturity, the group fed on D. salina (group D) attained the highest survival rate, Group S was the lowest. Further more, The differences of the reproductivity among the groups were great significant (p<0.01). The reproduction frenquency, total numbers of offspring and the average numbers of offspring at each batch of reproduction of group W (5, 320 and 64 respectively) were all higher than those of group S (1.5, 63 and 42). The Artemia sp. of group D didn't reproduce in this experiment. It could be therefore concluded that wheat bran was the best food to culture Artemia sp. and most beneficial to both the growth of the individual Artemia sp. and the population propagation.
