Sea grape production process

Seaweed growing season

With sea grapes, it can be clear all year round because it only needs to meet the conditions of salinity above 30%, temperature level of 23 - 29 degrees and pH index of 7.5 - 8 and the bottom of the pond has sand or sand mixed with mud...

But please limit seaweed farming in the rainy season because the rain will make the farming efficiency not reach a high rate

Planting density

The appropriate density for farming in sea grapes is about 200 kg for 500m2 square, equivalent to about 0.2kg for 1 blister, 500m2 is about 1000 blisters.

- There are 3 main methods of growing seaweed: planting it directly on the bottom of the lake, on the floor, and on a blisters:

- Direct planting method on the bottom: use bamboo or wooden splints to fix the seaweed branches to the bottom of the lake, distance 40cm x 40cm, 200kg/500m2. With this method, sea grapes will grow very quickly, but when harvested, it will require a lot of labor.

- Method of looking at the floor: make a wooden floor 50cm x 30cm 5cm from the bottom. Take sand and build it up then plant it directly on the bottom. This method of planning is quick as grapes grow slowly due to lack of nutrients.

- Mesh method: sew 2 pieces of net into a 0.3m x 0.6m frame to fix the sea grapes in the mesh then release them in order of rows in the shirt. This method grows well and is easy to harvest, but the cost is higher than the other two methods.

Check the growth of algae every 2-3 days to remove impurities, fish, and crabs. Sea grapes are easy to grow to maturity and can be harvested after 3 months of cultivation.
