Abstract | S963; 以螺旋藻粉、酵母、酵母+β-胡萝卜素为饵料,分别在不同盐度(10、30、50、70和90)和不同温度(20、25和30 ℃)下,探究饵料对卤虫(Artemia sp.)生长及体内类胡萝卜素积累的影响.结果表明:相同温度盐度条件下,投喂螺旋藻粉组卤虫存活率和体长优于其它饵料组;养殖第10天,在温度25 ℃下投喂螺旋藻粉组和酵母组卤虫均在盐度30时有最大平均体长(7.5 mm,5.9mm),而投喂酵母+β-胡萝卜素卤虫在盐度10时平均体长最大(4.0 mm);在盐度50下各饵料组卤虫平均体长在温度30 ℃组均显著大于其他温度组(P<0.05).养殖第15天,在温度25 ℃下投喂螺旋藻粉组卤虫在盐度30时存活率(93.7%)最高;在盐度50下投喂螺旋藻粉组卤虫存活率在温度20 ℃(94.0%)和25 ℃(92.0%)均显著大于30℃组(P<0.05).投喂螺旋藻粉各组卤虫抱卵率显著大于其他饵料(P<0.05),且随盐度或温度升高而逐步增大.对养殖15 d卤虫体内类胡萝卜素检测表明,各饵料组卤虫均只检测到海胆酮和角黄素,未检测出β-胡萝卜素、β-隐黄质、玉米黄质和虾青素.投喂螺旋藻粉卤虫总类胡萝卜素含量显著高于其他组(P<0.05),且随盐度升高呈下降趋势,盐度10组最高(46.25 μg/g);随温度升高呈先上升后下降趋势,温度25 ℃组最高(46.28 μg/g).综上所述,投喂螺旋藻粉的卤虫生长最好,卤虫可以将β-胡萝卜素转化成海胆酮和角黄素,温度升高会降低卤虫存活率,加快卤虫生长、性成熟及类胡萝卜素代谢;盐度过高或过低会降低卤虫存活率和生长速度,但是高盐可以促进卤虫性成熟,且消耗体内类胡萝卜素. |

Abstract_FL | In this paper,Spirulina powder,Yeast,Yeast+β-Carotene were used as feed to explore the effects of feed on the growth and carotenoids accumulation of Artemia at different temperatures(20℃,25 ℃,30℃)and salinities(10,30,50,70,90).The results showed that the survival rate and body length of Artemia fed with spirulina powder were better than those of other feed at the same temperature and salinity.On the 10th day,at 25℃,Artemia fed with spirulina powder and yeast had maximum average body length at salinity 30(7.52 mm,5.88 mm)(P<0.05),while Artemia fed with yeast+β-carotene had the largest average body length(4.0 mm)at salinity 10(P<0.05).The average body length of Artemia in the 30℃ group was significantly longer than that in the other temperature groups at salinity 50(P<0.05).On the 15th day,at 25℃,Artemia fed spirulina powder had the highest survival rate(93.7%)at salinity 30.At salinity 50,the survival rate of Artemia fed with spirulina powder in the 20℃ group(94.0%)and 25 ℃ group(92.0%)was significantly higher than that in the 30℃ group(P<0.05).The egg-holding rate of Artemia in each group fed with spirulina powder was significantly higher than that of other feed(P<0.05),and gradually increased with the increases of salinity or temperature.After 15 days,the detection of carotenoids of Artemia showed that only echinenone and canthaxanthin were detected in each feed group,and β-carotene,β-cryptoxanthin,zeaxanthin and astaxanthin were not detected.The total carotenoid content of Artemia fed with spirulina powder was significantly higher than that of other groups(P<0.05),and decreased with the increase of salinity,and the salinity 10 group was the highest(46.25 μg/g).With the increase of temperature,it first increased and then decreased,and 25 ℃ group was the highest(46.28 μg/g).In conclusion,Artemia fed with Spirulina powder grew best,Artemia could convert β-carotene to echinenone and canthaxanthin,with the increase of temperature,the survival rate of Artemia decreases,which accelerates Artemia growth,sexual maturity and carotenoid metabolism.If the salinity is too high or too low,the survival rate and growth rate of Artemia will be reduced,but high salt can promote sexual maturity and deplete carotenoids in Artemia. |
