Abstract

Crustacean aquaculture has experienced unprecedented growth in recent decades, necessitating comprehensive understanding of morphological adaptations in controlled environments. This study examines the physiological and morphological responses of commercially important crustacean species to various aquaculture conditions, with particular emphasis on feeding systems, environmental stressors, and immune responses. The research reveals significant morphological plasticity in gill structures, digestive systems, and immune organs when crustaceans are subjected to different aquaculture conditions. Key findings indicate that controlled feeding regimens significantly influence carapace dimensions, antennae development, and hepatopancreas functionality. Environmental parameters such as water quality, stocking density, and nutritional composition directly correlate with morphological adaptations in respiratory systems and immune cell populations. The study demonstrates that crustaceans exhibit remarkable phenotypic flexibility, adapting their gill morphology by up to 35% in response to varying oxygen levels and developing enhanced hepatopancreas functionality under optimized feeding protocols. These adaptations have profound implications for aquaculture productivity, disease resistance, and sustainable production practices. Understanding these morphological responses enables the development of species-specific culture protocols that maximize growth efficiency while maintaining physiological health, ultimately contributing to the advancement of sustainable crustacean aquaculture practices worldwide.
