Hermaphroditic gonads were collected from three skipjack tuna Katsuwonus pelamis in the western and central Pacific Ocean. Both ovarian and testicular tissues were found in the same gonad lobe for each of the three fish. Histological sections of the hermaphroditic gonad from one K. pelamis showed postovulatory follicles, which is evidence of spawning.
从西太平洋和中太平洋的三条鲣鱼（Katsuwonus pelamis）中采集了雌雄同体性腺。在这三条鱼的每一条中，在同一个性腺叶中都发现了卵巢和睾丸组织。对一条鲣鱼的雌雄同体性腺进行组织学切片检查，发现了排卵后的卵泡，这是产卵的证据。
