Description

A kind of algae fish mixed type stereo ecological fish shelter and put-on method thereof
Technical field
The present invention relates to a kind of algae fish mixed type stereo ecological fish shelter, belong to the sea fishery technical field.
Background technology
Along with the marine fishery resources decline, the offshore waters desertification is serious day by day.Countries in the world are by the various manual construction things (artificial fish shelter) in marine setting; phase reaches and improves the marine site ecotope; build the environment that marine organisms perch; for aquatiles such as fish, shrimp, shellfish, algae provide breeding, growth, forage and shelter enemy's place, reach the purpose of protecting the marine environment, improving cultivation effect and improve catch.Carry out the artificial fish shelter construction at present both at home and abroad widely, carried out the reparation in the biological habitat of coastal ocean and fishing ground, obtained effect preferably.
Find through consulting the relevant patent library of China, China has relevant artificial fish shelter patent 80 remainders at present, mostly be at single varieties such as fish, sea cucumber, abalone, algae designs artificial fish shelter, do not find at algae and small fishes or the juvenile growth mixed type fish shelter of perching at the middle and upper levels.
Summary of the invention
The objective of the invention is to design a kind of algae fish mixed type stereo ecological fish shelter, can be at the middle and upper levels small fishes or juvenile fish the growth habitat is provided, and can breed and culture algae, to overcome the deficiencies in the prior art.
A kind of algae fish mixed type stereo ecological fish shelter, comprise the mooring system that is constituted with anchor and the anchor tail rope that links to each other of sign float respectively by anchor, main push-towing rope rope, auxiliary cable, two ends, it is characterized in that also comprising fish shelter top, fish shelter middle level and fish shelter bottom, described fish shelter top comprises the fixed frame that the dependence ball float floats on the water surface; Described fish shelter middle level comprises a fixed frame that is provided with horizontal grid, ball-type fish shelter in the middle of being hung with on this fixed frame, and the fish shelter top is connected by the fixed frame of connecting rope with the fish shelter middle level; Described fish shelter bottom comprises a fixed frame that is provided with horizontal grid, is hung with bottom ball-type fish shelter on this fixed frame, and the fish shelter middle level links to each other by vertical cross grid with the fish shelter bottom; Described main push-towing rope rope one end links to each other with anchor, the other end is connected with the fixed frame in fish shelter middle level via auxiliary cable.
In order to improve the availability of this stereo ecological fish shelter, can set up a plurality of fish shelters middle level, namely between above-mentioned fish shelter top and fish shelter bottom, be provided with at least two fish shelter middle levels, and link to each other by vertical cross grid between the fish shelter middle level.
The fixed frame of above-mentioned fish shelter top, fish shelter middle level and fish shelter bottom is cirque structure.
Two projections with holes are arranged at ball-type fish shelter top in the middle of above-mentioned, are used for the colligation of middle ball-type fish shelter at fixed frame, and there is circular hole the top of middle ball-type fish shelter, bottom and side, boring.
Two projections with holes are arranged at ball-type fish shelter top, above-mentioned bottom, are used for bottom ball-type fish shelter colligation at fixed frame, and there is circular hole top and the side of bottom ball-type fish shelter, boring, and in the ball-type fish shelter of bottom stone is housed.
Above-mentioned fish shelter top relies on ball float can float on the water surface, and the connection cord length between the fish shelter middle level of fish shelter top and its below relies on throws in marine site transparency decision, is beneficial to the required degree of depth of ground floor algal grown and determines.
About 1.5 meters of distances between the fish shelter middle level, the number of plies are according to the algae of throwing in the marine site and the small fishes degree of depth of living in and the depth of water are definite at the middle and upper levels.
The put-on method of above-mentioned algae fish mixed type stereo ecological fish shelter comprises number of assembling steps, namely by connecting rope and vertical cross grid fish shelter top, middle level and bottom is assembled into an integral body; Four auxiliary cables in symmetrical colligation on the fixed frame of the second layer below the fish shelter top layer then, general two fixing point spacings are 1/4 circular arc, main push-towing rope rope and anchor, anchor tail rope and sign float in the connection, it is characterized in that further comprising the steps of: with ship this stereo ecological fish shelter is transported to and throws in the marine site, earlier throw next anchor meeting flow path direction, second anchor thrown in out in following current in order then, there are anchor tail rope and sign float in anchor rear end system, by following current towing anchor tail rope, the tensioning whole system, input finishes.
One aspect of the present invention can be used for algal culture and the propagation of the different depth of waters, can be used on the other hand small-sized pelagic fishes and large-scale pelagic fishes juvenile fish perch and keep away ground the place.The present invention is assembled together ball float, circular fixed frame, ball-type fish shelter and horizontal grid and vertical cross grid and constitutes the floating fish shelter of sandwich construction vertical distribution in water, use anchor and hawser with its Gu Bo in specified sea areas, portable is suitable for the algae that the different depth of waters are grown with adhering on the grid, forms the algae field of a three-dimensional.Fish shelter interlayer and ball-type fish shelter (boring) are perched and are kept away harmful animal for providing the small fishes at the middle and upper levels of different depth activity or large-scale fish juvenile fish, and can provide algae as food, form a small-sized three-dimensional, ecotypic ecotope.
The whole apparatus structure of the present invention is simple, and assembling easily, and is easy for installation, is convenient to reclaim, and can be to set up environmental oceanic pasture a kind of novel artificial fish shelter is provided.
