Abstract

The invention discloses an artificial propagation method of Octopus ocellatus in an outdoor earth pond. The method comprises the following steps: a) setting up a propagation isolation region; b) putting parent Octopus ocellatus and promoting maturity of the parents; c) incubating fertilized eggs; d) obtaining early-stage bait for larva; and e) preventing the larva from escaping. The culture process disclosed by the invention has the characteristics of high larva survival rate, low culture cost, high yield, simple method and easiness in management and is suitable for coastal open-air earth pond propagation of Octopus ocellatus. The method disclosed by the invention has the advantages that the Octopus ocellatus yield can be obviously increased and higher economic benefit is obtained. According to the invention, the large-scale artificial propagation of the Octopus ocellatus is realized through the design of an outdoor propagation earth pond, the building of an isolated propagation region of the parent Octopus ocellatus and the effective control on links of promoting maturity of the parent Octopus ocellatus, incubating the fertilized eggs, preventing the larva from escaping and the like. The popularization of the process has very important significance in realizing the large-scale artificial propagation and culture of Octopus ocellatus.

Description

Short octopus outdoor earth pond artificial fecundation method
Technical field
The invention belongs to technical field of aquaculture, relate to a kind of short octopus outdoor earth pond artificial fecundation method specifically.
Background technology
Short octopus (Octopus ocellatus Gray, 1849) belongs to mollusk Cephalopoda (Cephalopoda), Octopodida (Octopoda), octopus section (Octopodidae), octopus genus (Octopus).China north and south is coastal all to have distribution, and the perch of main colony is marine site by north in the temperate zone, yellow, Bohai Sea output is bigger; The Qingdao in Shandong, Yantai, Weihai; The Dalian in Liaoning, Yingkou, the Leting output in Hebei is more, is one of most important economic kind in the northern coastal octopus class of China.Along with the increasing of fishery catching intensity, the natural resources and the blastogenesis diversity of short octopus are being faced with serious day by day destruction in recent years.Simultaneously, raw and fresh food, dry product and the processed goods of short octopus all have wide market at home and abroad, and along with the increase day by day of domestic market consumption and demand for exports, people also increase the demand of short octopus year by year.
Short octopus is cultured in China and is also failed to form industrialization; Its main cause is natural fishing for because the seed source places one's entire reliance upon; Therefore, carry out short octopus mass artificial and breed and culture extremely urgent, carry out the artificial propagation of native pond and be the effective measure of originating of a kind of solution seed.At present, the new varieties that short octopus is cultured as the north, its fast growth just can reach the above commercial specification of every 60g half a year, receives numerous raisers' favor.How can provide a kind of scientific and effective short octopus soil pond artificial fecundation method to become vast short octopus raiser's active demand.
Summary of the invention
The present invention provides a kind of scientific and effective short octopus outdoor earth pond artificial fecundation method in order to overcome the deficiency that prior art exists.
The present invention realizes through following technical scheme: a kind of short octopus outdoor earth pond artificial fecundation method, it comprises the steps:
A, breed the setting of isolated area:
Adopt the breeding way of the native pond of outdoor manual work seawater, the degree of depth of native pond seawater is 2～3m, and use mesh diameter is that the polythene net of 0.5～0.8cm crosses parent enclosure cultivation waters;
The input of b, octopus parents and parent accelerating:
When water temperature >=16 of outdoor earth pond ℃, with body weight 80g and above male and female parent according to female: male=ratio of 3: 1 is invested in said parent enclosure and cultivates the waters; The shellfish of throwing in some low values in said parent enclosure cultivation waters is is in advance thrown something and fed according to the feeding volume of every close octopus 3～5 little assorted crabs of live body every day as living body bait, after finding have parent to begin to lay eggs, and the little assorted crab of no longer throwing something and feeding;
C, incubating oosperm:
Under the nurse of close octopus, fertilized egg hatched young octopus through 40～50 days, pulled the close octopus of having laid eggs then successively out, and the hole natural distribution that young octopus then sees through said polythene net arrives Tu Chi everywhere, young octopus is carried out the management of forming stage;
The acquisition of d, the early stage bait of the young:
Locating to be provided with the mesh number in water inlet and discharge outlet (7) is the large-scale protozoa screen packs of 80 purposes (6).Filter and collect large-scale protozoa, as the early stage living body bait of the young.E, the young prevent to escape:
Adopt nature Na Shui to culture, the day exchange rate of native pond maritime interior waters is 10%, and water inlet and discharge outlet all are provided with anti-escape net and large-scale protozoa screen pack, and the anti-order number of escaping to net is 10 orders, and the mesh number of large-scale protozoa screen pack is 80 orders.It is the large-scale protozoa screen packs of 80 purposes that the mesh number is set, for the short octopus young obtains early stage bait.
The area in said parent enclosure cultivation waters is 1: 50 with the ratio that outdoor earth pond is bred the area in waters, and parent head number is 0.08～0.1/m with the ratio that outdoor earth pond is bred the area in waters 2
Cultivate the waters at the parent enclosure and throw in tile and make and supply close octopus to perch the veil that adheres to fertilized egg, veil is piled up along the water inlet direction.
Said veil adopts three triangular in shape tying up of tile for building, piles up in the Yu Tuchi along the water inlet direction, and line space is 3 meters.
The invention has the beneficial effects as follows: cultural technique of the present invention has that larva survive ratio height, aquaculture cost are low, high efficiency, method is simple and the characteristics that are easy to manage, is applicable to that the short octopus breeding of coastal open-air Tu Chi uses.The present invention can obviously improve short octopus output, obtains high economic benefit.The present invention sets up the enclosure of octopus parents and breeds the district through the outdoor Tu Chi of breeding is designed, and parent is carried out accelerating, incubating oosperm and prevents that link such as young escape from controling effectively, and realizes the large-scale artificial breeding of short octopus.The popularization of this technology is for realizing that short octopus large-scale artificial is bred and breed has very important significance.
The present invention sets up parent enclosure cultivation waters through being provided with; The release time and the female-male proportion of control octopus parents, live in caves place and prevent technology such as escape of close octopus is provided; Promptly satisfied perching and the nutrition supply problem of octopus parents mating season; After overcoming octopus parents end breeding period again, the problem that dead parent causes water body to degenerate.Simultaneously, according to primary productivity and the food chain relation of Tu Chi, disposable or muptiple-use input low value shellfish and low-quality shell-fish, short octopus and the synchronous growth of living body biological bait have guaranteed the supply of the daily bait of parent.After the incubating oosperm, can be to its large-scale protozoa of throwing something and feeding, these measures make that the quality of fertilized egg is high, good in economic efficiency.
