Abstract

The utility model discloses an appliance for breeding cuttlefish fertilized eggs out of water, and relates to cephalopoda breeding of aquiculture. The utility model needs to provide an appliance for breeding cuttlefish fertilized eggs out of water, and the technical scheme of is as follows: a fish tank, a shower nozzle, a water pump and a water pipe are adopted. The appliance for breeding cuttlefish fertilized eggs out of water is characterized in that a crossbar is arranged above the fish tank and used for hanging a spawning rope or a spawning stick; the fertilized eggs are stuck on the spawning rope or the spawning stick out of water; sea water is filled in the fish tank; the water pump pumps water in the fish tank, and is connected with the shower nozzle through the water pipe; the water sprayed out by the shower nozzle drops on the fertilized eggs and then returns to the fish tank; therefore, the water can be recycled for use.

Description

The utensil of the dried up hatching of a kind of Sepiella maindroni fertilized egg

Technical field

The utility model relates to the dried up hatching of aquaculture siphonopods fertilized egg, especially cultures the dried up hatching of fertilized egg of Sepiella maindroni.

Background technology

Sepiella maindroni is distributed widely in Russian Yuan Donghai, the rapids indoor sea of Japan, the contiguous marine site of Korea's southwest seashore and China, mainly concentrates on China Zhejiang and ALONG COASTAL FUJIAN.Be called as " four big marine products " with big little yellow croaker and hairtail.Because the cuttlefish height contains protein, nutritious, eating mouth feel is pure, is traditional table delicacies delicacy, liked by the consumer, always occupies important share on market.Because overfishing, the stock number of Sepiella maindroni obviously reduces, and germ plasm resource also shows the sign that comparatively significantly fails.Therefore, carry out propagating artificially of Sepiella maindroni and not only help improving current fishery economic situation, the resource recovery of Sepiella maindroni is had crucial effects equally.The beginning of this century, domesticly in succession the artificial breeding of Sepiella maindroni some research work have been carried out.At present, the domestic artificial breeding that solved substantially such as manually forms at a difficult problem, but the low problem of the hatchability of fertile eggs of artificial breeding delays to be improved, and general incubation rate is only about 10%.Because Sepiella maindroni development of fertilized ova speed has certain difference, the time that differs is about 10 days.Under the situation of hatching in water, after first seedling hatched, the ovum of also not hatching water mold can occur on every side in several days afterwards, has a strong impact on still unhatched fertilized egg hatching rate.Therefore, need a kind of more effective mode of hatching,, improve the fertilized egg hatching rate in the hope of reducing the possibility that produces water mold.

The utility model content

The problem that the utility model need solve provides a kind of Sepiella maindroni fertilized egg hatching rate that improves, and reduces the hatching apparatus of the generation of incubating oosperm disease in period.

The technical solution of the utility model adopts fish jar, shower nozzle, water pump, water pipe, it is characterized in that having set up cross bar above the fish jar, cross bar hangs the lay eggs rope or the rod of laying eggs, fertilized egg is dried up to be sticked on the lay eggs rope or the rod of laying eggs, and dress is fit to hatching salinity, the seawater of pH condition in the fish jar, water pump draws water in fish jar, water pump connects shower nozzle by water pipe, and shower nozzle ejection water droplet is sprinkled upon fertilized egg and upward returns afterwards fish jar, forms the recycling of water.

The beneficial effects of the utility model are simple in structure, easy to operate, meet the primary condition of Sepiella maindroni incubating oosperm, stop because the too high anoxic that causes of density of ovum, can effectively reduce the generation of saprolegniasis, thereby improve Sepiella maindroni fertilized egg hatching rate.

Description of drawings

What accompanying drawing was represented is the schematic diagram of the dried up hatching apparatus of a kind of Sepiella maindroni fertilized egg.

Embodiment

The utility model (seeing accompanying drawing) by suspension lay eggs the rope or lay eggs the rod horizontal pavilion 1, fish jar 2, shower nozzle 3, water pump 4, water pipe 5 form, cross bar is located at the fish jar top, cross bar hangs the lay eggs rope or the rod of laying eggs, fertilized egg 6 dried up sticking on the lay eggs rope or the rod of laying eggs, lay eggs the rope or the rod of laying eggs hang dried up 10-20cm, the hatching of being fit to salinity is arranged in the fish jar, the seawater of pH condition, water pump draws water from fish jar and connects shower nozzle by water pipe, open water pump when shower nozzle is worked apart from fertilized egg 20-30cm., shower nozzle is gone up uniform sprinkling toward the fertilized egg string.

Claims

1. the utensil of the dried up hatching of a Sepiella maindroni fertilized egg, adopt fish jar, shower nozzle, water pump, water pipe, it is characterized in that having set up cross bar above the fish jar, cross bar hangs the lay eggs rope or the rod of laying eggs, and fertilized egg is dried up to be sticked on the lay eggs rope or the rod of laying eggs, and dress is fit to the hatching salinity in the fish jar, the seawater of pH condition, water pump draws water in fish jar, and water pump connects shower nozzle by water pipe, and shower nozzle ejection water droplet is sprinkled upon fertilized egg and upward returns afterwards fish jar.

2. the utensil of the dried up hatching of a kind of Sepiella maindroni fertilized egg according to claim 1, it is characterized in that the laying eggs rope or the rod of laying eggs are hung dried up 10-20cm.

3. the utensil of the dried up hatching of a kind of Sepiella maindroni fertilized egg according to claim 1 and 2 is characterized in that shower nozzle is apart from fertilized egg 20-30cm.
