Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention discloses a fishing tackle for freshwater shrimp seedlings, which includes a net cage 1 provided with at least one opening 11, and the net cage 1 is used to hold caught shrimp seedlings. The fishing tackle disclosed in the present invention also includes a catching net 4 for catching the fishing target and a blocking net 7 to prevent the fishing target from escaping. The catching net 4 and the blocking net 7 are respectively arranged on two opposite sides of the opening 11 of the cage 1 . Specifically, the length of catching net 4 is 1.3 times to 1.8 times of the width of the pond, so that operators can cover the whole pond with catching net 4 when in use, so that a catch can obtain the maximum catch; the height of catching net 4 It is 1.3 times to 2 times the water...

Abstract

The invention discloses a fishing tool for macrobrachium nipponensis seeds. The fishing tool comprises a net cage, an expelling net and an intercepting net, wherein the net cage consists of a cage frame and a mesh, one end of the net cage is provided with an opening, and the expelling net and the intercepting net are respectively arranged on two opposite sides of the opening of the net cage. By skillfully combining the expelling net, the intercepting net and the net cage, the fishing tool for the macrobrachium nipponensis seeds has a simple structure and low cost; when the fishing tool is used, the conventional expelling, intercepting, spreading and fishing methods are effectively combined; the whole fishing process is operated in water, so the fished objects are not hurt; and the fishing tool effectively reduces the death rate of the fished objects, can realize full-pool fishing at one time, has high fishing efficiency and low labor intensity, and is favorable for large-scale fishing.

Description

technical field [0001] The invention relates to a fishing tool, in particular to a fishing tool for freshwater shrimp and a method for using the same. Background technique [0002] Macrobrachium nipponensis (Macrobrachium nipponensis), commonly known as freshwater shrimp, is an important freshwater cultured shrimp in my country. According to the 2010 National Fishery Economic Statistical Bulletin, the total output of freshwater shrimp in my country in 2010 was 225,600 tons, with an annual output value of more than 7 billion yuan. With the continuous expansion of the scale of freshwater shrimp farming, the large-scale breeding of fine varieties is also imperative. In addition to the large-scale breeding of seedlings, which requires excellent germplasm and rich natural bait, the non-lossy fishing of the grown shrimp seedlings is also a key technology to improve the yield and quality of shrimp seedlings. At present, the traditional fishing methods for shrimp seedlings include...
