Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a harvesting apparatus and a marine biological larval-

The present invention relates to a harvesting device and a marine biological larval and a marine biological sampling device using the harvesting device. More particularly, the present invention relates to a harvesting device for harvesting marine life larvae And to a marine biological larval and subseal sampling apparatus using the same.

Various devices have been disclosed for collecting subspecies in marine biological larvae or coasts in general.

Particularly, the suspended solids are substances which are suspended in water and are insoluble or insoluble in water to filter paper (glass fiber bed, GF / C) as 0.1 mu m as untouched material. This subtype (SS) is obtained by filtering the water and drying the material remaining on the filter paper at 105 ~ 110 ℃ for about 2 hours, and measuring the mass, it is expressed as mg / L. This is an important factor influencing the sedimentation change of the terrain subsurface terrain. Quantitative measurement should be done through collection. Especially, it is very important to acquire accurate data through capture at shallow coastal depth.

The sub-pseudo-collecting apparatus according to the related art is a Korean Registered Utility Model No. 20-0370601 (public notice: December 13, 2004), and has a structure in which collecting means are respectively provided on a rectangular frame as shown in Fig. However, such a collecting device can not be applied to an inclined bottom surface because the collecting means is constituted by fixing the collecting means to the frame, and there is a problem that accurate collection is difficult.

In addition, most marine organisms go through a small young larval stage to a large adult stage. The survival rate from the young stage to the adult stage is lower for the offspring 's survival rate. Because it is less likely to survive, many individuals will be produced, and if only a few of them will become adults and multiply, the species will not become extinct and will be well preserved. In marine biology, basically the basic ecology of a living creature must be known to make it easier to approach the study of that creature. However, the above-described prior art pseudo-collecting apparatus has a problem that marine organisms can not be collected.
