Problems solved by technology

At present, there are only a few species of anchovy that have been successfully artificially propagated, but in the process of artificial propagation, there are difficulties in collecting the required mussels in the wild, the mussels are easy to carry pathogens, the life span of the mussels is severely shortened, and the mussels die suddenly during the hatching of eggs. Dead river mussels are easy to pollute water quality and other problems, which in turn affects the reproductive efficiency of squid

Embodiment 1

[0021] Embodiment 1: refer to Figure 1 to Figure 4 , a kind of hatching device for collecting and hatching fish roe, comprising a simulation mussel 1, a connecting pipe 2 and an incubator 3, the rear end 10 of the water inlet pipe in the simulation river mussel 1 is connected to one end of the connecting pipe 2, and the other end of the connecting pipe 2 is connected to the incubator 3 The front cover water inlet 12 in the connection.

[0022] Imitating the structural features of the clam, the simulated clam 1 is designed to include two closed simulated clam shells 4, an outlet pipe 5, an inlet pipe 6 and a fixed fork 9, and an inlet pipe 6 and an outlet pipe 5 are arranged in parallel below the outlet pipe 5 and the water inlet pipe 6 pass through two closed simulated clam shells 4, and the cross sections of the water outlet pipe 5 and the water inlet pipe 6 inside the simulated clam shell 4 are oblate; the front end 7 of the water outlet pipe and the front end 8 of the wate...

Embodiment 2

[0030] Embodiment 2: If large-scale reproduction is carried out, the three gill balls 17 provided inside the device can absorb fertilized eggs in large quantities, and the incubator is disassembled to separate the front cover 13 and the rear cover 22, and the fertilized eggs can be observed on the gill sticks with the naked eye. Adsorption on the 26, if the gill rod 26 has been covered with fertilized eggs, the device can be transferred to the hatching pond for hatching, or the gill ball 17 covered with fertilized eggs can be replaced, and the device can be placed in the original place Fertilized eggs are collected, and the replaced gill ball 17 is transferred to a dark hatching tank for hatching. When hatching, it is necessary to maintain the continuous circulation of the hatching tank water to provide sufficient oxygen, and the hatching temperature is 20-30°C. The device can be used indoors or outdoors. When used outdoors, it is also possible to collect a large number of fer...

Abstract

The invention discloses a rhodeus sinensis roe collection and hatching device. A simulated clam of the device is connected with a hatcher through a connecting pipe, a water outlet pipe and a water inlet pipe are arranged inside the simulated clam, and a front hood and a rear hood of the hatcher are fixed together through a fixed clamp; a gill ball is arranged in the middle of the hatcher, a gill ball catheter is arranged on the lower end of the gill ball in a penetrating manner, and the lower end of the gill ball catheter penetrates through a gill plate hole in the gill plate; gill bars are evenly distributed on the gill ball; a peristaltic pump water inlet pipe is connected with the rear end of the hatcher, a peristaltic pump water outlet pipe is connected with the rear end of the water outlet pipe of the simulated clam, the peristaltic pump drives water flow to flow in from the front end of a water inlet pipe of the simulated clam and flow out from the water outlet pipe above the front end of the water inlet pipe, so that the rhodeus sinensis zygotes are adsorbed on the gill bars of the gill ball and grow and develop on the gill bars until to be juvenile fishes. The device is simple to operate and strong in stability, the pathogenic bacteria infection rate and mortality rate of the juvenile fishes can be effectively reduced, the fertilization rate and hatchability can be increased by 20-30%, and the device can be widely used in interior and exterior propagation and cultivation of rhodeus sinensis.

Description

technical field [0001] The invention belongs to the field of carp fish breeding, and in particular relates to a device for collecting and incubating the eggs of carp carp. Background technique [0002] Rhodeus ocellatus belongs to the genus Rhodeus of Cyprinidae. There are 5 genera and 23 species in my country. It is a small wild freshwater fish with bright and gorgeous appearance. It is widely distributed in my country and has a high Scientific research, ornamental and food value. Anchovy has the characteristic that it must rely on river mussels for reproduction. Anchovy parasitizes fertilized eggs on the gills of river mussels, and the fertilized eggs hatch into juveniles on the gills. [0003] At present, in the development of my country's fishery industry, the fish resources of bream are facing a trend of gradually decreasing. At the same time, due to the pollution of the water environment and harmful substances exceeding the standard, the number of mussels that maintain...
