摘    要:1994年4~9月调查结果表明,东山湾海域霞水母的密度高峰期出现在6月25日~7月10日,生物量高峰期在7月10~8月5日;群体的伞径分布范围15~580mm,平均247.48mm,体重分布范围0.4~10250g,平均1274g;高次方程模拟的伞径生长方程式为Φt=15.1726+16.7204t+0.1926t2-0.0014t3—0.0004t4,指数高次方程模拟体重生长方程式为logeWt=-0.6885+1.3397t-0.0959t2+0.0034t3—0.00005t4;以生物经济学原理确定合理开捕为7月15日,合理开捕伞径为360mm.还讨论了表层水温和盐度与霞水母生物量和密度的关系及其资源开发等问题.

关 键 词:霞水母  密度  生物量  生长  开捕期  东山岛海域

Abstract:According to the investigations during April-September 1994, the peak date of Cyanea nozakii density of in the waters of Dongshan Island was from 25 June to 10 July,and that of its biomass was from 10 July to 5 August. The diameter of umbrella part of the stock ranged from 15 mm to 580 mm, averaging 247.48 mm,and the body weight ranged from 0.4 g to 10 250 g, averaging 1 274 g. The growth of the diameter of umbrella part and the body weight of Cyanea nozakii could be calculated using power equation and power exponential equation,respectively. Based on the bio economics principles,the optimal opening date was 15 July,and the rational fishing umbrella part was 360 mm
Keywords:Cyanea nozakii  Density  Biomass  Growth  Opening date
