In the breeding of Macrobrachium praecox and freshwater prawn, the method of net catching and the last dry pond is often adopted for fishing, which is labor-intensive and labor-intensive. After several years of observation and practice, I have found out a method of shrimping that requires less investment and can be manipulated by a single person. Now I introduce it as follows: I. Manual network capture 1. Handprinted nets were made from a bamboo basket with a diameter of about 4 cm and made into a triangular frame with a handle. The bottom was 60 cm in width, the waist was 90 cm in length, and the handle was 20 cm in length. A woven net was used as a mesh bag and the depth was 40 cm. 2. Set hidden species For shrimps like habits attached to objects in the water, place a certain number of hidden species, such as abandoned chicken cages, baskets or branches, bamboo branches, etc., 1.5 meters offshore from the pond in advance. One, use a small rope to mark the plastic foam and hidden habitat. 3. Collect and catch along the mark, slowly raise the hidden object with your right hand, dip the net with the left hand, copy the hidden object into the net bag in the water, and slowly take out the water, when the dip net frame emerges from the water, gently Dithering the occult, the shrimp falls into the net bag and then the shrimp is collected. Second, the net to catch 1. The mesh pocket is made from a length of 60 cm in length and is made of Velen. The bamboo raft with a diameter of about 1.2 cm is used. The four corners of the net are tied with a small string and the other end is tied to a bamboo raft. The bamboo raft is about 1.5 meters long. 2. Place the net bag in the net bag into the bait, mixed fish and other bait, use a small brick to sink the net bag in water. Insert bamboo poles obliquely in the raft so that the small rope floats on the water. Place 1 every 5 meters. 3. Grab two hand-held turtles, slowly raise the net bag, collect the shrimp, then put the bait in the net bag and then place it in the water. This method is applicable to Tangkou where there is less debris and aquatic weeds.
