Adult rice field eels with 125.52±27.99 g body weight corresponding to 44.79±5.93 cm in length were maturity cultured in a 5 m^2 cement tank without mud for three months with density 30 eels/m^*** broodstocks were fed with three types of food including:sea fish(T1),commercial pellet food(T2)and mixed food—50%sea fish and 50%commercial pellet food(T3).Result showed that the maximum gonadosomatic index(GSI)of female eels fed by sea fish(2.89%±0.67%)was higher than both commercial pellet food(1.62%±0.62%)and mixed food(2.03%±0.82%)(P0.05).Maturity rate of female fed by sea fish(88.91%±9.64%)was higher than commercial pellet food(61.12%±9.64%)(P0.05).*** eels were induced for spawning with two kinds of hormones,including T1:human chorionic ganadotropin(HCG)at 1,500 IU/kg,T2:luteinzing hormone-releasing hormone(LHRH-a)at 150μg/kg and domperidon 10 mg/kg,and T3:control without *** results of spawning induction methods showed that the reproduction rate of female eels induced by LHRH-a and HCG hormones were higher than that by natural reproduction method(P<0.05).Others,the survival rate of fry eels after 5 d using natural reproduction method(92.65%±2.54%)was higher than both using LHRH-a(67.77%±1.91%)and HCG(68.65%±1.23%)hormones(P<0.05).The average diameter of eggs was 3.40-3.41 mm and the length of newly hatched eels was 1.72±0.19 cm.

指出了生态旅游市场需求受到众多因素影响,而且各因素之间存在复杂的相关性,因素度量信息不足,所以可以将生态旅游市场需求预测系统视为灰色系统。以风雅-格邦国家公园为分析对象,基于预测模型GM(1,N),分析诸多因素对越南生态旅游市场需求的综合影响,主要考虑各因素之间的相关度基础上选择最合适的因素建立灰色预测模型,从研究结果中可以得到:影响生态旅游市场需求的因素之间,客源地的教育水平最具有相关性,其次是性别,收入以及旅游资源状况等,灰色预测模型的结果表明:2012～2021年越南生态旅游市场需求增长总体呈现上涨趋势,但增幅较为平缓。
