食蚊鱼

Mature male Gambusia affinis vitellogenin was induced by E 2 through exposure to the waterborne.

采用水体暴露的方法，用17β-雌二醇（E2）诱导性成熟的雄性食蚊鱼（Gambusiaaffinis）产生卵黄蛋白原。

Agrillo´s team found that mosquitofish can discriminate between numbers up to 16, but only if the ratio between the fish in each shoal was greater than 2:1.

阿格利罗的团队发现，食蚊鱼最多可以分辨大到16的两个数字的大小，但前提是每个鱼群中鱼的比例大于2：1。

Mosquitofish, freshwater fish with a taste for mosquito larvae, are highly social.

食蚊鱼是淡水鱼，以蚊子幼虫为食，高度的群体化。

When a mosquitofish finds itself alone, its top priority becomes finding others.

当一只食蚊鱼发现只有它自己时，当务之急就是找到其它的伙伴。

´They fly low over the water and catch surface-feeding fish, such as the mosquitofish, with their claws,´ Aihartza said.

“它们会低飞到水面，然后用它们的爪子抓取表层鱼类，例如食蚊鱼，”Aihartza说。
