Description
Technical Field
The invention belongs to the technical field of bottom sowing of seafloor buried shellfish, and particularly relates to a precise bottom sowing device for buried shellfish and a use method thereof.
Background
The proliferation and release of aquatic organisms are one of the main ways of natural resource recovery, and are important links of maintenance and repair of an ecological system; wherein, propagation and release of buried shellfish refers to bottom sowing artificially bred shellfish offspring seeds into sea area lacking shellfish resources, recovering and increasing natural population quantity of shellfish; the buried shellfish mainly comprises part of clams, razor clams and other varieties of bivalve shellfish, and the enemy organisms mainly comprise starfish, conch, octopus, shrimp and crab, and fish with strong bottom meat. At present, two common methods for propagation and release of artificial shellfish seedlings by bottom sowing are available:
firstly, a method for sowing seedlings on water, namely, after the shellfish seedlings are packed, the shellfish seedlings are transported to an open sea area by a transport ship, then the seedlings are directly sown on the water surface of a multiplication sea area by manual operation, so that the seedlings are automatically sunk into the sea area with large multiplication area, but the accuracy of sowing the seedlings is poor, the shellfish seedlings are easily carried away by ocean currents in the process of sinking the sea area, and the shellfish seedlings are randomly distributed to all parts of the sea area, and are generally required to be sowed in a horizontal flow;
secondly, the underwater seeding method is that the diver submerges the sea floor to uniformly broadcast the shellfish seedlings in the proliferation sea area according to the required density, the method requires the diver and the personnel on the ship to operate simultaneously, the labor intensity is high, the seeding efficiency is low, but the seeding is uniform, and the effect is ideal.
Further, as the sand-diving rates of different varieties of the buried shellfish are different, the variety with higher sand-diving rate can be quickly transferred into the buried life, and the slow sand-diving is possibly taken away by water flow or predated by enemy, thereby reducing the survival rate of the shellfish seedlings; for example, the Arca inflata Reeve which is one of the main proliferation and release varieties of the buried shellfish at present occupies a large amplification proportion due to the excellent economic character, and the sand-diving rate can reach a high peak value after 8-24 hours of seeding of the offspring seeds.
Specifically, two commonly used seedling sowing methods for propagation and release of the shellfish seedlings have advantages and disadvantages (see the first and second above), and the two methods find limitations after consulting the prior art: for example, the invention name: the invention is mainly applicable to a reef-based substrate sea area with flat sea surface, and the bottom-sowing shellfish variety is mainly snails growing on the surface of a reef; further, another name is: the invention provides a shallow seabed sowing device for benthonic shellfish fries and a use method thereof (application number 201610258649.2, application date 2016.04.25), which provides 'cleaning and improvement of seabed', and performs the sowing after loosening soil, but has the following problems:
Firstly, seeding still depends on manual work, the working strength is high, and the seed distribution uniformity depends on the proficiency of manual operation;
secondly, the shellfish seedlings fall on the surface layer of the seabed, and the varieties with low sand diving rate still can be taken away by water flow or predated by enemy;
thirdly, most of sea areas with bottom sowing proliferation are within 20m from the intertidal zone to the water depth, and when the sea areas are used for sowing seedlings in a large range, the water depths are different, the ground surface at the sea bottom is fluctuant, and the like.
Based on the technical problems existing in the bottom sowing of the seafloor spats, no relevant solution exists yet; there is therefore an urgent need to seek an effective solution to the above problems.
