After the Philippine seedlings are attached, they grow after 5 to 6 months of growth. The body length is generally 0.5 cm and they can be harvested. Picking time is mainly from April to May every year. Picking method: not the same everywhere, there are dry tidal seedlings, shallow water seedlings and deep water seedlings. The first two methods are used to sprinkle intertidal zone seedlings, and the latter method is suitable for seedlings below 10m in depth under the tide.
(1) Dry tidal power seedlings: When the seedlings are collected, the seedling mites are divided into a number of plots, usually 5m square, with a swing plate with seedlings to advance 70-80cm, and the advancing sand should be evenly spread, and the second and third tidal flows are similar. And then we'll loosen up. Each time after the push, the seedling food climbs up and concentrates on the surface when the tide rises. When the seedlings are concentrated on a small area of ​​1 to 1.5m square or a 0.5m wide strip, when the requirements for washing seedlings are reached, the seedlings may have sand. Scrape the seedlings on the sieve and wash them clean to obtain the seedlings.
(2) Shallow water picking: The seedlings are divided into small pieces of about 8m squares at the time of dry tide. Four weeks of seedlings adjoin the sand to promote the leveling. When the tide rises, the seedlings climb upwards and concentrate on the surface. Then the central open up a space with a diameter of about 3m. After a tidal wave, push the surrounding seedlings to the middle and call it “push the heap†and insert the mark. Then you can wash the seedlings. When washing the seedlings, the people drove the boat and when the tide retreated to about 1m from the surface, the water was standing around the seedlings and hitting the water with their feet to push the seedlings toward the central tightly integrated pile. Finally, the bamboo shoots were used to remove and wash. , Loading in the boat.
(3) Deep-water seedlings: on the ship with polyethylene gel mesh fishing. First select the anchoring position, relax the anchorage cable, and the ship will retreat to 30~50m under the net. Then the winch will be closed and the cable will advance. The net will follow the ship and the seedling will be scraped into the net bag. Set up the net 10m away from the anchor, pull the net rope, wash the mud, and pour the seedling into the boat. Then repeat the above process.
