Description
Technical field
The invention belongs to the mariculture technology field, specifically, relate to a kind of seabed integrated culture device that participates in Patinopecten yessoensis that stings.
Background technology
Stichopus japonicus (
Apostichopus japonicus) be one of precious kind in China marine products economic animal, scrape or sweep take tentacle and get bottom sediment (such as organic chip, some bacterium and protozoa etc.) as food.Stichopus japonicus not only is a kind of delicious food and health food, is again the high marine drug of medical value.Along with the raising of socioeconomic development and people's living standard, demand increases day by day the epoch to this.
Patinopecten yessoensis (
Patinopecten yessoensis) belong to the cold water shellfish, have individual large, grow fast, economic benefit advantages of higher.After beginning to introduce China the eighties in last century, through research of technique and research for many years, obtained breakthrough progress at artificial breeding and cultural technique, in Liaoning of China, the large-area cultivation in ground such as Shandong, bring huge economic and social benefit.Cultured output at northern Yellow Sea Patinopecten yessoensis has reached 150,000 ton/years at present.Broadcasting propagation at the bottom of the extensive style is present main breeding way, is about to the above seed of 3cm and is sown in the seabed, and the density of broadcasting seedling is generally 8-10/m
2, adopt by the form of diver or trawlnet and to catch.Survival rate is subjected to the impact of substrate condition and harmful organisms (starfish etc.) larger, and lethality is high, and the rate of recapture is low, adopts the cost of catching high.In addition, it is higher to the substrate conditional request that propagation is broadcast at the end, is subjected to the restriction of substrate condition, and propagation scale and Arrested Development are broadcast in the end of Patinopecten yessoensis.In order to enlarge the scale of cultivation, increase the income of cultivation, need the improvement of breeding facility and cultural technique badly.
The integrated culture of many trophic levels (IMTA) is based on a kind of aquaculture model of ecosystem-level management, food web angle from the whole ecosystem, comprise elementary, secondary integrated culture to high trophic level, make the metabolic waste of putting into nutriment superfluous in the cultivating system and a kind of aquaculture organism become the source of nutrition of another kind of aquaculture organism, recycling by to nutriment, reach and both alleviated the pressure of cultivation to environment, improve again the diversity of breed variety and the purpose of economic benefit, promoted the sustainable development of aquaculture industry.
According to above-mentioned theory, the seabed integrated culture device of studying a kind of suitable stichopus japonicus and Patinopecten yessoensis is extremely urgent.
Summary of the invention
The objective of the invention is the problem for existing stichopus japonicus, Patinopecten yessoensis cultivation existence, research and develop the seabed integrated culture device that a kind of novel thorn participates in Patinopecten yessoensis, its design be coupled biology, the ecological characteristics of stichopus japonicus and Patinopecten yessoensis can solve the problems such as the rate of catching is low, cultured product poor quality of adopting that prior art exists.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of seabed integrated culture device that participates in Patinopecten yessoensis that stings, described device comprises three-dimensional bracket, top at three-dimensional bracket arranges two-layer culturing area at least, surround with etting respectively around every layer of culturing area, the culturing area of the bottom is used for culturing stichopus japonicus, etting in its bottom is fixedly installed some stichopus japonicus blindages, the culturing area of remainder layer is used for the cultivation Patinopecten yessoensis, between the two opposite side surfaces etting of Patinopecten yessoensis culturing area, be fixedly installed some vertical ettings, some three-dimensional string bags are set on the vertical etting of each bar.
The vertically etting setting of standing, the plane that refers to vertical etting place is vertical with the etting plane of bottom, like this, some three-dimensional string bags vertically can be set on the etting be used for the cultivation Patinopecten yessoensis, the three-dimensional string bag is opening up, can prevent Patinopecten yessoensis because of asecretory byssus set, run foul of each other, interlock damage, the survival rate of Effective Raise Patinopecten yessoensis.
The present invention is according to biology, the ecological characteristics of Patinopecten yessoensis, stichopus japonicus, research and develop a kind of device that is suitable for seabed many nutritive salt level integrated culture, to take full advantage of the complementarity of space, marine site and variety classes ecological niche, improve cultured output, reduce environmental pressure.
In the integrated culture of stichopus japonicus+Patinopecten yessoensis, stichopus japonicus can play repair to environment to the feeding activity of the biodeposition of Patinopecten yessoensis.
Further, every one deck culturing area wherein the etting of a side zipper opening is set.By slide fastener, put seedling, sampling and results during convenient cultivation operation.
Wherein, described stichopus japonicus blindage comprises the baffle plate of semicircular blindage body and blindage body both sides, and barrier width 50cm arranges the circular hole of diameter 4.8cm at the blindage body, and described stichopus japonicus blindage is the PVC material, the long 15cm of specification, high 6.75cm.
The circular hole of diameter 4.8cm is set on the stichopus japonicus blindage, and the activity that is conducive to stichopus japonicus takes food.Design the baffle plate of wide 50cm in the both sides of semicircle, increased the activity space of stichopus japonicus, simultaneously, be conducive to the enrichment of organic debris.
Further, the between layers employing sleeve pipe of described three-dimensional bracket is pegged graft.Adopt between layers sleeve pipe to peg graft, can independent assortment, dismounting, according to the cultivation needs, be combined into the multilayers such as bilayer, three layers.
