Functional Spermatogenesis Across Testicular Developmental Stages in Neomale Large Yellow Croaker (<i>Larimichthys crocea</i>) Revealed by Histology and Gonadal Specific Cellular Markers.

ABSTRACT: Gonadal development and spermatogenesis critically influence fish reproductive performance. Neomales (genetically female but functionally male) are indispensable for generating all-female populations, yet their spermatogenesis remains understudied. In the present study, we systematically investigated gonadal maturation in neomales of the large yellow croaker (Larimichthys crocea), an economically important marine species exhibiting sexually dimorphic growth. We examined the growth performance and gonadal development throughout the maturation process in neomales and control males. Results showed comparable growth performance but a temporal divergence in gonadal development: the gonadosomatic index (GSI) of neomales was significantly higher than control males at 400 and 430 days post-
