Prevention and Control of Invasive Mussels in Hard Clam Ponds
This year, biological control research was carried out on mussels that have entered the clam pond, mainly divided into plankton and adult mussels that have just entered the pond. For the removal of plankton of mussels, the feeding and removal efficiency of shrimp seedlings in clam ponds was used to study the feeding and removal efficiency. The experimental species included bearded shrimp, white shrimp, grass shrimp, sand shrimp, and monodon shrimp; , Plastic, nylon and other materials are put into it, and its adhesion situation is observed, and its adhesion situation is observed in different environmental positions (surface, bottom, flow area, slow flow area), etc. For the biological control of adult mussels, black bream, yellow tin bream, sequoia and blue crab were put into the clam ponds with mussels to observe the reduction of mussels. During the experiment, the growth and survival of clams were observed to find out The most suitable method is to understand the ability of various organisms to remove mussels, which can be used as a reference for fishermen to increase the income of clams.
