Abstract

The invention relates to a burrowing-type shellfish rearing seedling catching device for a sandy and muddy sediment pond and an application method. The catching device comprises an arc-shaped bracket,a connecting angle iron, a net bag, a support rod and fixing rods, wherein connection holes are formed in the arc-shaped bracket and a horizontal wing plate of the connecting angle iron at intervals;two ends of the arc-shaped bracket are fixed to two ends of the horizontal wing plate of the connecting angle iron; a vertical wing plate of the connecting angle iron is located at the bottom of thefront side of the horizontal wing plate; a net opening of the net bag is connected to the arc-shaped bracket and the connecting angle iron through the connection holes and the net bag is located at the rear sides of the arc-shaped bracket and the connecting angle iron; one end of the support rod is connected with the middle of the arc-shaped bracket and the other end is flush with the connecting angle iron; and two sides of the support rod are symmetrically supported and reinforced at two ends of the connecting angle iron through the fixing rods separately. According to the burrowing-type shellfish rearing seedling catching device, the problem that it is difficult to catch burrowing-type shellfish in the sandy and muddy sediment pond can be solved in a targeted way, the catching difficultyis reduced, the catching efficiency is improved and damage to seedlings is reduced.

Description

technical field [0001] The invention belongs to the technical field of fishery catching equipment, and in particular relates to a catching device and a use method for buried shellfish cultivation seedlings in ponds with sandy muddy bottom. Background technique [0002] my country has a vast sea area and a long coastline. It is estimated that the area of ​​coastal tidal flats is about 150 million mu. Marine shellfish farming is the main form of utilization of coastal tidal flats. According to statistics, marine shellfish farming accounts for about 70% of the total amount of marine aquaculture, and is one of the most important marine aquaculture economic species. my country's economic shellfish are mainly buried shellfish and sessile shellfish. Among them, the cultured varieties of buried shellfish include meretrix meretrix, razor clams, Philippine clams, clams, and American hard shell clams. They have a wide range of breeding and huge output value. Habitat-type shellfish cult...
