摘要

来自切萨皮克湾下游的24条北方河豚的繁殖力数据表明，300毫米长河豚的产卵量可达50万枚。左侧卵巢平均比右侧大1.6倍。尽管卵巢大小存在物理差异，但吉尔森溶液处理过的卵巢的卵子在左右卵巢中大小相同。繁殖力与体长和体重的关系。

Fecundity of the northern puffer,Sphoeroides maculatus, from Chesapeake Bay

Fecundity data for 24 northern puffer from the lower Chesapeake Bay indicate production of up to 0.5 million eggs by 300 mm TL fish. The left ovary averaged 1.6X larger than the right. Despite the physical difference in ovary size, eggs from Gilson’s solution treated ovaries were of equivalent size in both left and right ovaries. Fecundity versus total body length and body weight are presented.
