Mark-release-recapture estimation of population density was performed with mosquitofish in a rice field habitat. Regression analysis showed a relationship between absolute density and mean number of fish per trap. Trap counts were converted to density estimates with data from several fields and growth curves were calculated to describe seasonal growth of mosquitofish populations at three different initial stocking rates. The calculated curves showed a good correspondence to field populations of mosquitofish.
在稻田栖息地，对食蚊鱼进行了标记重捕法以估计种群密度。回归分析表明绝对密度与每个诱捕器中鱼的平均数量之间存在关系。利用来自多个田地的数据将诱捕器计数转换为密度估计值，并计算生长曲线以描述三种不同初始放养率下食蚊鱼种群的季节性增长。计算出的曲线与食蚊鱼的田间种群表现出良好的对应关系。
