The first evidence of intersexuality in Atka mackerel Pleurogrammus monopterygius (Hexagrammidae). Zygote. 2021 Jan 15;:1-3 Authors: Zhukova K, Golovatyuk GY Abstract Histological examination of Atka mackerel ovotestes reveals the possibility of intersexuality. Individuals with bisexual gonads have been caught in the North Pacific near the south-east coast of the Kamchatka peninsula. While intersex appeared to be normal females with developing ovaries, histological analysis showed the presence of both female and male tissue in the same gonad. Specifically, primary growth, cortical alveolar and primary vitellogenic oocytes were located among spermatogonia cysts. The prevalence of intersexuality in the population was less than 0.1%.
