What Is Mussel Farming?

Mussel (scientific name: Mytilus edulis), also known as Haihong, also known as Qingkou, is cooked into a dry product-mussels. It is a bivalve mollusk with a dark brown shell and lives on rocky seashore. Distributed in the Yellow Sea, Bohai Sea, and East China Sea coasts. The mussel shell is wedge-shaped, with a narrow tip at the front and a wide and round end. Generally, the shell length is 6-8 cm, and the shell length is less than twice the shell height. The shell is thin. The shell top is near the forefront of the shell. The two shells are equal, left and right symmetrical, the shell surface is purple and black, with luster, the growth lines are fine and obvious, and they grow in a ring shape from the top.

The inner surface of the shell is off-white, the edges are blue, and there is pearl luster. The hinge is longer and the ligament is dark brown, about the same length as the hinge. Underdeveloped hinge teeth, rear

There are many ways to eat mussels, especially emerald mussels, such as

I. Aquaculture area and equipment

1. Breeding sea area The breeding sea area should choose the open sea area with fresh water and smooth water flow. Due to the shortcomings of poor water exchange, relatively lack of bait, and easy pollution of water quality in the inner bay type sea area, the fertility of farmed mussels is not high and there is an odor such as diesel.

2. Raft for breeding Rafts for breeding are rafts for breeding scallops. Generally, the effective length of the raft is 80 meters, and the float is floated, the float is 3 meters long, and 30 ~ 40 floats are added at one time.

3. Breeding equipment The equipment for breeding mussels is two- or three-strand ropes made of rubber, 1.5 meters to 1.8 meters in length, weighing 1 kilogram to 1.5 kilograms, with a 2 meter long lanyard attached, and falling stones weighing about 0.5 kilograms. .

2. Feeding of breeding equipment Beginning in late March of each year, the fullness of mussels is tested daily. If mussels are found to suddenly lose weight and spawn in large numbers, they can be placed in time according to the breeding area and natural seedlings can be collected.

Third, the management of mussel farming is very simple. The daily work is to inspect the sea area to prevent broken frames and entanglements and adjust the buoyancy in a timely manner.

Fourth, harvest

1. Summer harvesting raft racks include artificially placed aquaculture equipment, floating stems, roots, slings, and floats that will attach a large number of mussel seedlings. According to the density and area of the seedlings to be harvested in time, the general mussels grow to 1 cm to 1.5 cm in July to start harvesting. One is to sell it to other breeding units for seedlings, and the other is to sell it to shrimp pond farmers for bait. When harvesting, all mussels that are attached to the rubber skin are peeled off. At the same time, mussels with good adhesion (about 0.2 kg to 0.3 kg each) are selected and clamped on the rubber skin, with an average of 5 to 6 pieces. If the mussels are not clumped, the seedling method can be used. Pack 1 kg to 1.5 kg of seedlings on rubber with a 20-mesh net, and tie them with a rope. After 3 days, remove the net. From the actual situation of breeding, the seedling method is convenient and the seedling method is troublesome, but the mussel cultured by the seedling method is better than the seedling method. Most of the mussels on the floating stalks, slings, roots and floats are harvested, leaving only about 5% for their continued growth, and a cage can collect more than 1,200 kg.

2. All harvests: All harvests are made in a timely manner according to market conditions before and after the Spring Festival. Each re-clamped raft can produce more than 2800 kg of mussels.
