Green Mussel Cultivation, Increasing Interest
Green mussel cultivation is a promising business opportunity that can be done in marine coastal areas. In addition to the profit generated is much greater, the business carried out is relatively easier than catching fish in the middle of the sea. Business capital to start is fairly efficient and does not require too much equipment. This causes the cultivation of green mussels is increasingly in demand.
Green mussel is one of the marine biota that is able to survive and breed in high ecological pressures without being disturbed. With these characteristics and adaptability, green mussel cultivation is an easy activity to do both as a cultivating business and as a side business.
Green mussels are a favorite seafood menu for the community because of their high nutritional content and affordable prices. Many are sold in various restaurants to seafood tent stalls, so the market demand is high.
There are several simple methods that can be used to cultivate green mussels, including:
Plug-in method
Cultivation of green mussels with this step-by-step method can be done by collecting seeds from nature, rearing up to harvesting green mussels. First, prepare a bamboo rod with a diameter of about 15-20 cm, then sharpen it at the base. Plug the sharpened bamboo into the bottom of the water regularly.
The length of the bamboo used depends on the depth of the water, at high tide or low tide. Next, add the part that is stuck to the bottom and the part that rises above sea level, approximately 50-100 cm. The top of the bamboo is used as a sign and also to make it easier to pull out when harvesting green mussels.
The top of the collector unit can be added to the hut as an observer of the collector. Add tied bamboo, installed parallel to the surface of the water to strengthen the bamboo from the influence of currents and waves. Also add a bamboo chart with ropes connecting the bamboo in the water.
The distance between bamboo varies between 0.5-1 meters depending on the fertility of the waters, the area of cultivation and the number of collectors installed. Allow a few days for the green mussel spat to stick and increase the number of green mussels. After a large number of green mussels, harvesting can be done.
Floating raft method
Green mussel cultivation using the floating raft method is usually used in locations that are specifically for green mussels enlargement and not the location of the seed source. The advantage of using this method is that it is easier to harvest.
Make a raft of bamboo or wood or a combination of both. Make a rebuttal with several empty drums, either plastic or metal drums. Next, do an anti-rust paint for the metal drum and complete it with anchors. This rebuttal is very much needed so that the raft is not easily damaged and sinks when cultivators work on it.
Provide a net or rope under it so that the green mussel seeds can collect properly. Allow a few days until harvest time, but don't forget to always check.
Step-by-step raft method
Cultivation of green mussels with the raft method is a method of cultivating green mussels which is a combination of the step-by-step method and the floating raft. Make sure the location of the raft has been calculated based on the high and low water if it is high or low tide. This calculation is important because it anticipates not experiencing drought.
Next, place the collector ropes onto the raft and try to keep each rope at a distance of about 1 meter. Then, let it sit and check periodically. In about 6 months, you can get a yield of about 20-25 kg for each rope.
Longline method/ span rope
This method is also called the long line, the way is to stretch 2 threads of collector hanging rope between 2 float drums. If you have a large number of drums, they can be strung lengthwise so that the collector will hang and produce a larger number. Try to keep the maximum distance between buoys, which is 10 meters. Also make sure that each collector weighs 30-40 meters.

Make the distance between the hanging collectors, which is 1 meter. Hanging collectors can be asbestos, coconut shells, ropes, or seed bags. Put the seeds in the seed bag and place them in water, then let them sit for a while, but do regular checks. After producing and ready to harvest, the green mussels are ready to be removed.
