Mollusc aquaculture has gained global importance due to its economic value, nutritional benefits, and environmental sustainability. Recent developments in hatchery and farming technologies have significantly improved seed production, survival, growth, and overall productivity. Advances in broodstock conditioning, induced spawning, larval rearing, nursery systems, water treatment, and selective breeding have strengthened hatchery operations. Modern farming methods such as raft culture, rack culture, longline systems, cultchless oyster farming, and integrated multi-trophic aquaculture have enhanced production efficiency and resource utilization. Smart technologies including sensors and digital monitoring are further supporting sustainable expansion of mollusc farming worldwide.
