ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn ( Penaeus monodon ). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐induction strategy in aquaculture. Despite its effectiveness, the endogenous mechanisms that naturally overcome GIH‐mediated inhibition remain poorly understood, and only a limited number of stimulatory factors have been identified. As a result, the neuroendocrine and molecular regulation of reproduction throughout the ovarian maturation cycle remains incompletely resolved. Advancing this knowledge is essential for developing effective alternatives to ESA. This review synthesizes current advances in the neuroendocrinology of ovarian maturation in P. monodon , identifies key knowledge gaps, and summarizes molecular approaches evaluated as potential replacements for ESA. Collectively, this review supports ongoing efforts to develop sustainable and animal welfare‐friendly spawning‐induction strategies for P. monodon aquaculture.
