Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fishing ground creation system that creates a new fishing ground in any sea area, and in particular, transmits data such as fish schools, sea conditions, weather, etc. from the fishing ground to a base station by radio. The base station processes and stores the data and provides appropriate instructions.

[Conventional technology]

More than 99% of Japan's current fish production comes from coastal areas (approx. 9.9%) and outpouring areas (approx.
．． 1%), and most of the i area remains underutilized.

For this reason, even if efforts are made to increase the amount of fish caught, international relations,
They are constrained by various factors such as cost, and are in a situation where they cannot do what they want.

[Problem that the invention seeks to solve]

A system is needed to increase the production of marine resources by creating new fishing grounds in sea areas that currently do not have fishing grounds, and to redevelop existing fishing grounds, as well as to conduct economical fishing.

What I would like to note here is that the production volume of the entire coastal area and the total upwelling area are estimated to be approximately the same, and from this, the productivity of the upwelling area (per unit area) is approximately 100 times that of the coastal area. be.

From the above, if upwelling water can be obtained, unused sea areas may become promising fishing grounds, and existing fishing grounds such as coastal areas may also be expected to dramatically increase production.

[Means for solving problems]

The present invention solves the above problems by pumping up deep water from the sea, multiplying phytoplankton, protecting and nurturing young fish and young fish, and installing a floating fishing reef that provides shade to collect migratory fish. Detects the type and size of adult fish.

Furthermore, in order to manage and operate the fishing ground formation system, it is necessary to observe oceanographic data such as wave height, wave shape, seawater temperature, and seawater salinity, as well as meteorological data such as wind direction, wind speed, temperature, and atmospheric pressure. These data are also useful as general oceanographic and meteorological information.

The above-mentioned fishing, sea and weather information sent by radio from the fishing ground formation system is received at a base station installed at a fishing port, etc., and the data is processed and stored, and specific details are sent to the fishing ground formation system as necessary. The base station commands the collection of information and determines whether fishing is good and whether the local sea conditions and weather are suitable for fishing, thereby making it possible to conduct economical fishing.
