刺参升温苗成活率的比较及经济效益分析

摘要

为更好地控制刺参(Apostichopus japonicus Selenka)苗种质量,提高经济效益,对采用室内控温、控光技术促熟产卵、孵化培育的升温刺参苗与常规温度刺参苗比较出苗成活率、发病率和经济效益.结果表明,升温苗的成活率比常温苗提高15.8％,发病率降低10.2％,经济效益提高21.6％.该结果为刺参人工育苗提供了有效的技术支撑.%In order to control the spawning quality and improve the economic benefit of Apostichopus japonicus Selenka,the indoor temperature and light control methods were employed for artificial maturation,spawning and hatching of A.japonicus,and the larval survival rate,disease incidence rate and economic benefit were analyzed.The results showed that compared with those of conventional temperature-reared larvae,the survival rate of raised temperature-reared larvae was increased by 15.8％,the disease incidence rate was reduced by 10.2％,and the economic benefit was improved by 21.6％.These results will provide theoretical basis and technical support for the artificial breeding of A.japonicus.
