Description
Technical field
The present invention relates to lake Corbicula fluminea repopulate technology, be specifically related to broadcast propagation Corbicula fluminea method at the bottom of a kind of lake.
Background technology
Corbicula fluminea (Corbicula fluminea M ü ller) is lobe cheek guiding principle bivalve, is the economic species in lake, Jiangsu, and its meat flavour deliciousness is firmly got domestic and international consumer's favor.At present, the lake fisherman depends on the Corbicula fluminea natural resources unduly, catching intensity is far longer than the speed of natural resources propagation, cause lake Corbicula fluminea resource to fall sharply, the Corbicula fluminea natural resources shortage, group structure presents and becomes younger and miniaturization, meanwhile but lacks to improve Corbicula fluminea population structure method and effectively increase lake Corbicula fluminea total resources approach.The control measures although taked to prohibit fishing etc. in some lakes, because the lazy weight of this lake Corbicula fluminea reproductive population, fertility descends, from numerous reason such as germplasm degeneration that causes, demanding upgrading Corbicula fluminea germ plasm resource urgently could Effective Raise Corbicula fluminea stock number for many years.Some lakes are owing to a large amount of minimizings of benthon Corbicula fluminea, and the lake also presents eutrophication.
Summary of the invention
The present invention solves is that the stock number that the natural Corbicula fluminea in existing lake presents descends, population structure is unreasonable and the problem such as water body in lake eutrophication, at the bottom of being provided, a kind of lake broadcasts propagation Corbicula fluminea method, the method can be enriched lake Corbicula fluminea population structure, effectively increase the Corbicula fluminea resource, improve lake ecological environment, reduce the lake eutrophication level.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Broadcast propagation Corbicula fluminea method at the bottom of a kind of lake, comprise the steps:
1) press following quality standard and select Corbicula fluminea a species of small clam living in fresh water kind: the physique stalwartness, anosis nothing is hindered, and housing is intact, and the shell look is yellow, brown Huang or light/dark balance, and shell face concentric circles wheel arteries and veins is thin and even; Internal organ are intact, and the meat grossness is yellowish pink tender white, without pathology and parasite, and ventral margin and shell synchronous growth, the soft and resilient healthy individual of matter;
2) barricade is set:
When the propagation waters is the local waters in lake, need by design barricade area pilespacing 3m～4m to be pressed in stake and insert in the mud of breeding the waters, show and enclose the location and enclose shape; When propagation waters when being full lake, need by pilespacing 2m one campshed to be set with connection, loke shore limit front 2 meters of the entery and delivery port in lake; 0.8m～1m in the mud is inserted in the stake bottom; By the thread gang rope of polyethylene 20 * 3 nets, infraclass is recorded into the gabion that diameter is 15cm with stone, sequentially puts into water along the net sheet that stake will prepare in barrier net up and down twice on chip, and infraclass adopts earth anchor to insert in the mud, and the infraclass gabion should go deep into bed mud simultaneously; Raise to the higher plane of principle and fasten with gang rope and stake; The height of the barricade that barrier net sheet and stake form is higher than long-term peak level 1m;
3) broadcast preparation at the bottom of a species of small clam living in fresh water kind: remove black carp, carp, snakehead, river crab and soft-shelled turtle etc. in the barricade waters, the fingerling stocking structure in a species of small clam living in fresh water waters is supported in improvement: increase and put bighead, reduce silver carp, stablize grass carp, crucian, do not put out to graze fish, carp, river crab are to promote the Corbicula fluminea growth;
4) broadcast water area condition at the bottom of the Corbicula fluminea seed: unhurried current water, flow velocity is 0.1m/s～0.6m/s, more than the dissolved oxygen in water 5mg/L; The pH value is neutrality or alkalescence; Depth of water 0.5m～2.5m, transparency 50cm～100cm; Water quality should meet the regulation of " GB11607 water quality standard for fishery "; Water-bed shale or husky shale, physical features is more smooth, and substrate meets the regulation of " the nuisanceless aquatic products home environment of GB/T18407.4 agricultural product security quality requires ";
5) end is broadcast: a species of small clam living in fresh water kind is sowed equably into water body, and a species of small clam living in fresh water kind specification is in the long 0.5～0.8cm of shell, individual weight 0.5～1 gram, and 1500～2200 of per kilograms are thrown in 10～20 kilograms every mu of density;
6) production management:
6.1 the water quality situation in young a species of small clam living in fresh water periodic monitoring cultivation waters is broadcast at the end, periodic measurement Corbicula fluminea shell is long, the indexs such as body weight;
6.2 check other biodynamic: other biology comprises benthon, pasture and water and harmful organisms; When other benthon area coverage of spiral shell or freshwater mussel etc. in the lake greater than 30% the time, tissue is fished for listing, improves the lakebed situation; When the pasture and water area coverage greater than 30% the time, can take to cradle to remove; Make regular check on barricade, the discovery breakage should in time be repaired, to prevent the intrusion of the Corbicula fluminea natural enemies such as black carp, carp, snakehead.
7) commodity a species of small clam living in fresh water is fished for: in 1 year after broadcasting the end of at, should not fish for, should allow Corbicula fluminea that the end is obtained to adapt to completely and breed with broadcasting.Broadcast a species of small clam living in fresh water smooth transition after 1 year the end of when, Corbicula fluminea has adapted to environment of Lake region, and growing and fattening and smoothly breeding just can begin fishing for of 2 years one-periods.
