Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a lobster and crab mixed breeding continuous cropping aquaculture method which includes the steps: (1) pond selecting and cleaning; (2) escape-proof facility arrangement; (3) water grass planting; (4) young lobster and crab stocking; (5) feed adding; (6) water quality adjustment; (7) lobster and crab harvesting. According to the method, a temporary culture pond and an intensive culture pond are arranged and used for breeding young crabs and young lobsters, the crabs are transferred into the intensive culture pond to be bred after the lobsters mature then are fished, scientific feed and environmental management are combined, all fed baits and any use operations are rejected during shelling of the lobsters and the crabs, injury to the lobsters and the crabs during dormant period is avoided, aquaculture time and space can be furthest utilized, the survive rate of the crabs is increased, and economic benefits can be effectively improved.
