摘要

The mangrove or mud crab (Scylla spp.) is among the most commercially important aquaculture species owing to its high demand in both local and international markets. However, the rapid expansion of farming activities has resulted in the intensive collection of wild stocks, posing a significant threat to natural populations. To address this, the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) has developed basic larval rearing and nursery protocols for the farming of mangrove crabs. Despite these advancements, the hatchery production of seedstock remains insufficient to meet the growing demand for farming. One major challenge is the inconsistent larval quality in hatcheries, which is largely attributed to inconsistent broodstock performance. While numerous studies have explored both internal and external factors influencing the reproductive performance of mangrove crab broodstock in captivity, the findings remain fragmented. This review compiles existing research on mangrove crab maturation, providing a comprehensive overview of advancements in broodstock conditioning. It aims to identify research gaps and encourage further studies to develop improved protocols for managing captive broodstock effectively.
