Abstract
The invention relates to a method for cultivating Hemifusus tuba with a net cage in a hanging way. In the method, a single-layer cage-shaped cultivating cage tool consisting of a cage plate (1) with the diameter of 45-50cm and a polyethylene net (2) with the mesh size of 0.5-1.5cm is used for cultivating young Hemifusus tuba with the average height of 30-40mm and the average weight of 2-3g in a hanging way and 10-15 young Hemifusus tuba are cultivated in each cage. The method comprises the following steps of: filling the young Hemifusus tuba in the cultivating cage tool; hanging in a hanging pond at a water layer with the depth of 0.7-1.4m, wherein the distance between every two adjacent cages is 0.2-1m; feeding the Hemifusus tuba with fresh oyster with shell every 10 days; cleaning the net cage before feeding, cultivating until harvesting time of the Hemifusus tuba. The method disclosed by the invention improves the living environment of the Hemifusus tuba to the maximum extent and reduces the diseases caused by the pollution such as residues, wastes and the like, and reduces the cannibalism phenomenon, thereby effectively improving the survival rate and the growth speed of the Hemifusus tuba; simultaneously, the method can reduce the feeding quantity, the feeding time and the labor intensity.
Description
Technical field
The invention belongs to the marine aquaculture technical field, relate to the shellfish artificial cultivating method, particularly a kind of cylinder mould hanging culture method of Trumpet shell whelk cultivation.
Background technology
Trumpet shell whelk Hemifusus tuba (Gmelin) is commonly called as " angle spiral shell; ring spiral shell ", it is the carnivorous shellfish that dwells the end of living in the ooze of subtidal zone shallow water depth 11～42m and argillo arenaceous, from distribution is arranged on the south the Zhejiang, coastal comparatively common on the south Guangdong and Guangxi Provinces, it is the relatively large economic gastropod in shallow sea, become the high 12～20cm of shell (approximately 150～300g), the maximum high 30cm of shell (more than the body weight 500g), the chitin heavily fortified point is thick, there are yellowish-brown or the fine and closely woven and short living fine hair shell skin of light brown in the shell surface, its meat delicious flavour, nutritious, commodity price is expensive, the expensive seafood of generic name, being loved by the people, is the higher edible shellfish of economic worth, enjoys a good market both at home and abroad and Hongkong and Macro market.The Trumpet shell whelk specification is 1～2/kg up till now, and the market procurement price is 380～400 yuan, and specification is that the commodity shellfish procurement price of 4～6/kg is 120～140 yuan, and economic worth is very considerable, and supply falls short of demand for product, is the higher fresh and alive marine product of earning foreign exchange through export.
At present, Chinese scholars mainly comprises the research report of Trumpet shell whelk: the basic theory of the aspects such as morphosis, ecological habit, reproductive biology, artificial breeding, artificial increasing cultivation's technology and the history of life and the research of applied biology.Be that CN101496500A discloses a kind of technique for cultivating Hemifusus tuba such as publication number, this technology is to utilize area to be 20m
2Culturing pool, lay the cement plate be covered with through hole in its bottom, the height of cement plate at the bottom of apart from the pond is 20cm, makes at the bottom of the pond and forms the space between the cement plate; Then at cement fast respectively lapping cloth and fine sand, at the bottom of the straight-through pond of water inlet pipe, an osculum is arranged at the bottom of the pond, outside the logical pond of osculum one end, the termination in the pond has the high plastic water pipe vertical with the water surface of a 70cm as drainpipe; It is 400～500/m that the spiral shell seedling begins breeding density
2, subtract gradually thinly along with growing up of individuality, the later stage cultivation density is 30～40/m
2Take a broad view of in the above-mentioned report, Trumpet shell whelk uses cylinder mould hanging culture technology all without relating in breeding process.
Summary of the invention
The object of the invention is to easily be subjected to the pollutions such as self excreta, residual bait for Trumpet shell whelk living environment and cause that the Trumpet shell whelk disease occurs, and this problem occurs in the phenomenon of cannibalism, a kind of effective Trumpet shell whelk aquiculture mesh cage hanging culture method is provided.
The present invention realizes above-mentioned purpose like this, and method for cultivating Hemifusus tuba with net cage in hanging way may further comprise the steps:
1. the preparation of breeding cage: breeding cage is made of cage dish, polythene net;
2. putting in a suitable place to breed of spiral shell seedling: breeding cage is put into hanging culture pond 0.7～1.4m water layer through thoroughly cleaning, beginning to put in a suitable place to breed the Trumpet shell whelk seedling after the sterilization with the breeding cage that is placed with the spiral shell seedling, and the cage spacing is 0.2～1m;
3. daily management: between the Trumpet shell whelk mature stage, threw something and fed in per 10 days with the fresh and alive oyster of shell 1 time, throw something and feed front removing oyster ghost and dirt at every turn, the inside and outside aufwuch of cleaning cage, and then drop into the fresh and alive oyster of capacity band shell.
Described cage dish comprises circle, and lower circle, support bar, dead lever, support bar Uniform Dispersion are welded between Shang Quan and the lower circle, and dead lever is welded on the lower circle.
Described breeding cage is the individual layer cage modle, cage order size 0.5～1.5cm; The diameter of described cage dish is 45～50cm.
High 30～the 40mm of average shell, the average weight 2～3g of described Trumpet shell whelk seedling.
The depth of water in described hanging culture pond is 1.5～2m.
Described Trumpet shell whelk seedling breeding density is that every cage is put 10～50 spiral shell seedlings in a suitable place to breed.
Described polythene net has mesh.
Facts have proved through cultivation, cage dish diameter is about 48cm, and every cage is put 20 spiral shell seedlings in a suitable place to breed, and culture efficiency is best.
Advantage of the present invention:
(1) farthest improves the living environment of Trumpet shell whelk, reduce the pollution such as self excreta, residual bait and the disease that causes occurs, and the phenomenon of cannibalism, thereby effectively improved survival rate and the growth rate of Trumpet shell whelk.
(2) reduce daily ration, feeding quantity, bait throwing in number of times and labour intensity.
