Abstract
The invention relates to an artificial algae field cultivation method characterized in comprising the following steps: stone blocks are manufactured; a natural sea area with less people, more reefs and more alga are selected as a natural seedling-raising place; ropes are tied on the stone blocks, and the stone blocks are sunk in the selected natural sea area for natural seedling-raising; when seedling-raising is finished, artificial algal reefs are obtained; the obtained artificial algal reefs are pulled up with the rope, and are placed and applied in a specific sea area, such that an artificial algae field can be formed. According to the invention, seedling-raising is carried out under a natural environment, and an additional seedling-raising pond is not needed. Compared with traditional artificial seedling-raising methods, the cost is greatly reduced, and more varieties of alga are attached. Also, a problem of eliminating alkalinity of a seedling-raising pond water area is avoided. The artificial algae field can be adapted to culturing of various fishes. The method has the characteristics of simple process, short time, low cost, and high adaptability. With the method, a good activity, growth and habitat place can be provided for mariculture, and marine life growth can be promoted. The method has great utilization value.
Description
Technical field
The present invention relates to a kind of breeding method of artificial algae field.
Background technology
Sea fishery aquaculture domestic at present, general is all carry out in net cage, but lacks the external condition being applicable to fish habitat in net cage, as algae field, simultaneously at the various sea anglings of coastal area exploitation, be also make the stock of fish more nervous owing to lacking algae field.
Algae field is the important component part of marine ecosystems, can be that multiple marine organisms provide habitat, lay eggs, raise an infant, forage and keep away the place of enemy, to improving surrounding environment, reduce seawater loads of nutrition, suppress red tide plankton, improve the solid carbon ability in ocean etc. there is important Ecology Action.But, in recent years due to environmental pollution, the reason such as to reclaim fields from the sea, degenerated in the natural algae field of China serious.Therefore in order to improve optimization marine environment, attract the more shoal of fish, for Fisheries Development provides resource endlessly, many artificial algae fields are there is, as the Chinese patent " a kind of artificial algae field and building method thereof " that the patent No. is CN201310659056.3, it is characterized in that, comprise some algal reefs linked together by static line, fixing extension seedling net between algal reef, extension seedling hangs with marine alga on the net and becomes algae, with marine alga seedling on algal reef, it is the form adopting algal reef and extension seedling net to combine, by marine alga seedling with become algae and introduce seabed simultaneously, ensure that the introducing effect of marine alga, shorten the construction schedule of sea jungle.But this method need in advance on algal reef with marine alga seedling, this carries out artificial breeding with regard to needs on stone, these algae is attached on stone and forms algal reef, and the variety protection of this mode not only cost but also algae is single.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of breeding method of artificial algae field, adopts and carry out nursery in natural environment, has that cost is low, algae species is many, adaptable feature.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of breeding method of artificial algae field, it is characterized in that comprising the following steps:
1) stone is manufactured;
2) the natural marine site that selection people is few, reef is many, algae is many is as natural nursery place;
3) by stone rope, sink in above-mentioned selected natural marine site and carry out nature nursery;
4) after nursery completes, be artificial algal reef, with rope the artificial algal reef manufactured pulled on and render to assigned address marine site again and carry out putting cultivation and can form artificial algae field.
As improvement, described stone adopts cement steel to make, and the size dimension of stone as required not etc., stone has and can place fixing through hole for rope, or rope is directly fixed on stone.
As improvement, the time of described natural nursery is 25 ~ 45 days, and the temperature height time is short, and the temperature low time is long.
Compared with prior art, the invention has the advantages that: adopt and carry out nursery under natural environment, nursery pond need not be set in addition, compared with traditional artificial breeding, cost greatly reduces, and the algae species of spatfall is many, there is not the problem eliminating nursery pond waters alkalescence yet, the cultivation of various fish can be adapted to.The present invention has that technique is simple, the time is short, cost is low, adaptable feature, is not only mariculture and provides good activity and grow the place perched, and can also promote that it grows, have great value.
Embodiment
A breeding method for artificial algae field, step is:
1) adopt cement block to make various stone, and have on stone and can place fixing through hole for rope, or rope is directly fixed on stone in cement block forming process;
2) the natural marine site that selection people is few, reef is many, algae is many is as natural nursery place;
3) stone is fastened rope, sink in above-mentioned selected natural marine site and carry out nature nursery, if stone is little, stone rope string can be sunk to together, the time of natural nursery changes with the height of temperature, when summer temp height, seedling raise period is about 25 ~ 35 days, when temperature is lower in the winter time, seedling raise period needs proper extension, is 35 ~ 45 days;
4) nursery is just floating on stone after completing the seedling of a lot of algae, is artificial algal reef, to be pulled on by the artificial algal reef manufactured and renders to the position, marine site of specifying again and carry out putting cultivation use, thus cultivated artificial algae field with rope.
The breeding method of artificial algae field of the present invention, adopt and carry out nursery under natural environment, not only cost is low, and the time is short, strong adaptability, provides good activity and grow the place perched for mariculture.
Claims (3)
1. a breeding method for artificial algae field, is characterized in that comprising the following steps:
1) stone is manufactured;
2) the natural marine site that selection people is few, reef is many, algae is many is as natural nursery place;
3) by stone rope, sink in above-mentioned selected natural marine site and carry out nature nursery;
4) after nursery completes, be artificial algal reef, with rope the artificial algal reef manufactured pulled on and render to assigned address marine site again and carry out putting cultivation and can form artificial algae field.
2. breeding method according to claim 1, is characterized in that: described stone adopts cement steel to make, and the size dimension of stone as required not etc., stone has and can place fixing through hole for rope, or rope is directly fixed on stone.
