Eyestalk ablation (ESA) is widely used in decapod aquaculture to induce maturation by altering endocrine function. While pronounced sexual dimorphism in growth and development is common in decapods, the endocrine regulatory mechanisms underlying sex-specific responses to ESA remain unclear. Here, we comprehensively investigated sexual dimorphic responses to unilateral ESA in the most important farming decapod— Litopenaeus vann...
