Description

Agricultural implements for mud flat farming {Agricultural implements for mud flat}

The present invention relates to farming equipment for tidal flat fish farming, and more specifically, to farming equipment for tidal flat fish farming that can conveniently adjust the depth, position, and angle of the plow that plows the mud flat using the traction force of the tiller.

As is well known, a mudflat is a flat land of sandy clay that is submerged in water during high tide and exposed out of the water during low tide. It includes pearl mudflats, mixed mudflats, and sandy mudflats, and has a diverse range of biota.

Tidal flats are buffer zones that connect land and sea and provide habitats and spawning grounds for various fish and shellfish. And while sewage treatment plants that purify rivers and seawater require maintenance costs, mud flats allow for natural purification while generating profits from fishing.

Tidal flats are home to a variety of organisms, including endangered species, and can be used as food or medical resources. Tidal flats are also used for tourism projects that take advantage of the unique scenery, and the mineral-rich mud is also used as a natural cosmetic.

Tidal flats have the function of regulating natural disasters and climate. In other words, by storing a large amount of water at the same time, it is possible to lower the high water level that can occur momentarily.

Korea's mudflats are suitable for the habitat of fisheries resources and have the characteristics of high productivity, but due to recent reclamation and reclamation, more than 800㎢ of mudflats have disappeared. In addition, many of the remaining mudflats have changed from highly productive sandy mudflats to pearl mudflats as the speed of coastal ocean currents has changed and the amount of sand inflow from rivers and streams has decreased due to large-scale seawall construction and reclamation projects.

Tidal flats are used as fish farms to produce clams and bamboo shoots, but due to the aging of fishermen and the decline in the fishing population, farm management has become poor, and as a result, the amount of pearl sediment in the fish farms has increased, simplifying the cultured varieties and reducing productivity. This is the situation.

In addition, as the area of mudflats suitable for aquaculture decreases, efforts to manage fisheries are reduced, accelerating the deterioration of fishing grounds, and the environment of mudflats is worsening due to organic matter introduced from land.

Accordingly, chemicals such as bottom quality improvement agents were sprayed to improve the environment of mud flats centered on pearls where organic matter contamination was severe and to remove sea worms, but the quality improvement agents did not work well in the contaminated bottom layer located below the surface layer of the mud flats. It was confirmed that chemical environmental improvement was not suitable as it not only did not penetrate properly but also caused the death of shellfish such as clams living in the mudflats.

To improve the physical environment, when the mudflat is exposed during low tide, a method of plowing the mudflat using a tillage device such as a plow is used, or a method of spraying a quality improvement agent after plowing the mudflat is used.

As a prior art related to a tillage device for plowing a mudflat, Republic of Korea Patent No. 10-1407567 (registration date June 9, 2014) ‘Tillage device for mudflats equipped with a ski board’ and Korea Patent No. 10-1555977 (Registration date: September 21, 2015) 'Tidal flat tillage device combining a hydraulic rotary and a plow' is disclosed.
