Hybrid Cultivation Technology of Crabs and Water Bamboo
Abstract：As everyone knows, good grass and water can raise good crabs. The role of aquatic plants in crab farming is evident. The main aquatic plant species currently planted in crab ponds are Elodea, Potamogeton crispus, and Hydrilla verticillata. Among them, Elodea is the most common. However, these three aquatic plants have their own advantages and disadvantages in actual production. Due to the summer of 2024 experiencing more than 30 days of high temperatures above 35°C, with the highest temperature exceeding 40°C, especially in ponds where Elodea was planted, there was a widespread phenomenon of aquatic plant rotting and blue algae outbreaks. Crabs had to stay at the bottom of the pond to avoid prolonged high temperatures. This led to hypoxia at the bottom, deterioration of the substrate, and chronic hydrogen sulfide poisoning. Their feeding decreased, their physical condition weakened, leading to problems such as difficulty in molting or loss of crabs starting from mid-August, even causing pond collapse.
