中国鲎由于具有很高的经济和药用价值,遭受大规模滥捕乱杀,鲎数量急剧锐减,目前我国鲎资源已面临枯竭的危险.人工育苗及海区放流是一种保护和恢复鲎资源种群有效可行的措施.我们从2004年7月至9月,在厦门水产技术推广站进行鲎人工授精,并以人工授精培育的鲎幼体为材料,模拟海区生态环境,自2004年10月14日至2005年3月15日进行鲎幼体钻沙、钻泥实验,并比较幼鲎在不同生态环境生长发育情况,共计152 d.结果表明,幼鲎具有钻入沙或泥的生活习性,且幼鲎在含沙或泥的海水比在普通海水中生长发育的情况更好.本实验结果为鲎苗海区人工增殖放流提供了实验依据.
Due to its high economic and medicinal value, China is suffering from massive indiscriminate arrests and drastic reductions in the number of resources that are currently at risk of depletion in our country. Artificial breeding and redevelopment in the sea area are a source of protection and restoration. Effective and feasible measures for the population. From July to September 2004, we carried out artificial insemination in Xiamen Aquatic Technology Extension Station and simulated the ecological environment in the sea area by using the artificial juvenile larvae as material, since October 14, 2004 The larva drilling and drilling mud tests were performed on March 15, 2005. The growth and development of young larvae in different ecological environments were compared for a total of 152 days.The results showed that young larvae had the habit of drilling into the sand or mud, and young鲎 It is better to grow and develop in seawater with sand or mud than in ordinary sea water.The experimental results provided experimental evidence for the artificial propagation and releasing of the seedlings in the sea.
