Problems solved by technology

In the process of seedling production and cultivation, usually due to the differences in the growth of each individual, some can get food, some can get less food, and some can even get no food, resulting in uneven growth of fish species and even mutual killing. The phenomenon of eating, eventually leading to low survival rate of fish species, affecting the benefits of fishery production

Embodiment 1

[0028] The breeding method of the carnivorous fish species high survival rate provided by the present embodiment comprises the following steps:

[0029] A fish breeding area is separated from the breeding pond with a separation net, and fish species are put into the fish breeding area after the water is released;

[0030] In the fish breeding area, place a fish feeding device with different specifications every 3-5m, and put feed into the feeding device once every 1.5-2 hours, so that fish of different sizes enter the feeding device with different specifications. Feed separately in the separation layer;

[0031] When the fish species grow to a length of more than 10cm, remove the separation net in the fish species breeding area, and let the fish species swim loosely in the breeding pond. Large-scale production and farming.

[0032] This method is suitable for fish species such as California perch, flower perch, catfish, chrysalis, and is also applicable to the cultivation of...

Embodiment 2

[0041] The method for cultivating fish fingerlings provided by the adopting sub-standard feeding device provided by the present embodiment comprises the following steps:

[0042] The culture pond used is as attached figure 2 Shown, select the size of culture pond 16 to be 3.0~5.0 mus, and culture pond is cleaned up, and culture pond can utilize original production culture pond to get final product, and depth of water remains on about 1.2m~1.5m, disinfects with unslaked lime, Before releasing the water, the amount of quicklime per mu is 60-80kg, and the whole breeding pond is splashed.

[0043] With plastic sieve tulle 14, culture pond is divided into the waters of 0.5~1 mu, is also provided with water wheel type aeration machine 15 outside the waters of separation network, releases water in the culture pond, and after removing harmful organisms in the water, in the culture pond Put the fish species in, and disinfect them with a bleach solution with a concentration of 5-10ppm...

Abstract

The invention relates to a carnivorous fish seed culture method with high survival rate, which comprises: (1) separating a fish seed culture area in a culture pond by a separating mesh, and putting fish seeds into the area after water is filled in the pond; (2) placing a feeding device according to different specifications in the culture area, putting feeder into the feeding device regularly, and making the fish seeds with different sizes fed in spacer layers with different specifications of the feeding device respectively; and (3) after the fish seeds are grown up, detaching the separating mesh of the fish seed culture area to perform mass production culture. The feeding device according to different specifications comprises a top cover and a chassis between which fences with different specifications are arranged; and the fences comprise an inner layer fence, a middle layer fence and an outer layer fence, which are in movable connection with the top cover and the chassis. The culture method and the feeding device according to different specifications can guarantee feeding sufficiency for the fish seeds, do not waste the feeder or pollute the water environment, and ensure the even growth and high survival rate of the fish seeds.

Description

technical field [0001] The invention relates to a method for cultivating fish species and a feeding device for species of fish, in particular to a method for cultivating carnivorous species with a high survival rate and a device for feeding fish species according to specifications. Background technique [0002] In aquaculture, water, seedlings and feed are the three major elements of aquaculture. Seedling production is a very important link, especially carnivorous fish, which have high economic value, and the survival rate directly determines the producer's income. benefit. In the process of seedling production and cultivation, usually due to the differences in the growth of each individual, some can get food, some can get less food, and some can even get no food, resulting in uneven growth of fish species and even mutual killing. The phenomenon of eating fish will eventually lead to low survival rate of fish species, which will affect the benefits of fishery production. ...
