Abstract

The utility model relates to a manual loach hatching device, which belongs to the fish breeding field and comprises a hatching workshop, a hatching pool, and a water pumping and drainage system. During the hatching period, the noise of the hatching workshop is controlled below 40db. According to the practical experiments, the effect of breeding loaches by the manual loach hatching device is favorable.

Description

Loach artificial seed hatching apparatus

Technical field

The utility model belongs to the fish culture field, is specifically related to a kind of loach artificial seed hatching apparatus.

Background technology:

At present, because the domestic and international market is increasing to the demand of loach, therefore cause the overfishing of wild loach seed, resource is deficient day by day.To become the development bottleneck that loach is propagated artificially.

The seed hatching of pass through at present still is a kind of half original way, both close loach is placed in the common hatchery in proportion, puts some pasture and water again and does and incubate bed, hatches naturally, and this technology brooding time is long, and survival rate is low.

Summary of the invention:

The utility model provides a cover to propagate loach seed hatching apparatus and hatching technique artificially.

1. the hatching workshop is built: build between seed hatching special-purpose vehicle, the workshop addressing will be built with brick mix structure away from highway and village.The workshop requires to ventilate, and transparent solar panel is installed at the top, and shade is arranged.Between the month loach incubation period, want the shading cooling at 3-8 during the direct projection of sunlight high temperature.

2. the hatchery is built: the hatchery is the oval pond of diameter 8M * 6M, and tank depth is 80CM, and Chi Shui is controlled at 30CM-60CM according to the culture-cycle needs, and the hatchery inwall guarantees smooth, avoids close loach to scratch.Be the bottom of a pan shape at the bottom of the hatchery, difference in height is 20CM.Be beneficial to draining.Have the oval isolated area of 1M * 2M in the middle of the hatchery, isolated area is isolated with 60 orders filter yarn purse seine.Isolated area bottom has draining and fish passage, be used for draining with the hatching of growing seedlings after, in the seed entering breed pond.(diagram 1)

3. culvert system: culvert system and circulation are equipped with in the hatchery, through culvert system and circulation, and control hatchery water temperature and flow rate of water flow.Water inlet is arranged on the middle part, hatchery, and each water inlet is spaced apart 3M, and 8-9 root water inlet is installed in each hatchery.Water inlet is an annular array, and each water inlet clockwise direction water outlet makes that Chi Shui is regular to circulate.In hatching process, according to circumstances regulate current with the control flow velocity, ossphere or seedling can evenly be distributed in water body, slowly roll.Be provided with gap on top, pond according to top 15CM, the water that surpasses gap enters cultures in the pond.The hatchery water temperature remains between 25-30 degree centigrade.In the isolated area bottom oxygen-increasing device is installed; Form aeration system by blower fan, tracheae, gas stone, blower fan is installed in the outside, workshop, with isolated noise; Cellular-plastic panels is installed in the system; Formed air curtain can make fish-egg or fry separate with fish corral during ventilation, prevents to abrade fish-egg or fry, also can reduce screen cloth simultaneously and stopped up by egg membrane or impurity.(diagram 2)

4. will there be acoustic isolation facility in the hatching workshop, and between the incubation period, hatching workshop noise will be controlled at below 40 decibels.

5. close loach breeding uses artificial insemination and natural mating mode to combine to carry out.Shorten incubation cycle, improve seed output and weed survival rate.The hatching back can forward in 7-9 days cultures the pond raising.Through the practice of some months, we have accomplished hatching workshop equipment construction and seed hatching test, and achieve success.

The present technique scheme is fairly simple, does not need embodiment.

Claims
