Embodiment Construction

[0017] In order to further understand the content of the invention of the present invention, the following embodiments are exemplified, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0018] see figure 1 , a long strip of green polyvinyl chloride 40-60 mesh induced fish nest mesh 1, which is 8 meters long and 0.5 meters wide, and two round steels with a diameter of 6 mm and a length of 0.3 meters are fixed rods 2 at the ends, supporting The rod is 13 No. 10 lead wires 3 and 6 No. 10 lead wires 4 with a length of 50 centimeters. These two are fixed ropes 5 with a length of 80 centimeters; The two ends of , 4 are hammered flat and all have the hole of φ 3 millimeters, also have the hole of φ 3 millimeters apart from two ends 10 centimeters at the support rod 4 of long 50 centimeters in addition, apart from fixed rope 5 central places 5-7 centimetres. A buckle; the left and right two short sides of the rectangular mesh 1 are respectively...

Abstract

The simulating fish nest for artificial propagation of fish fry includes rectangular net sheet, end fixing rod connected to the net sheet and with small holes, support rods fixed to the net sheet homogeneously, and fixing rope connected to the end fixing rod. The net sheet is made of green soft PVC similar to aquatic weed in natural water domain and can induce parent fishes to lay eggs and fertilize in high egg laying rate and fertilized egg collecting rate. The fish nest is tough and may be reused, may be designed in different forms and sizes and may be used widely.

Description

Technical field [0001] The invention belongs to fish breeding production facilities and applications thereof, in particular to a simulated fish nest for artificial breeding of fry and its use. Background technique [0002] Fish that lay sticky eggs in nature gather in places with aquatic plants when they spawn, and lay their eggs on aquatic plants to fertilize and hatch to produce fry. With the continuous development of aquaculture production in our country, especially the breakthrough of the artificial reproduction technology of the "four major family fishes", the seedlings of carp and other sticky egg-producing fish are carried out on a large scale. At present, the known artificial fish nests have used willow roots, red Materials such as root-gathered grass and palm chips are used as fish nests, but with the increase of seedling production and the change of natural environment, willow roots have become difficult to find, and due to the drying up of natural ditches, pits an...
