Abstract

PROBLEM TO BE SOLVED: To provide a medication culture and organic hydroponic circulation system without using agrochemicals by combining the fresh water fish and shellfish culture and hydroponic culture. SOLUTION: A nutrient salt solution 6 is automatically fed to water 5 having a constant temperature from a water feed tank 3 and a water temperature adjusting boiler 4 in a fish culture tank 2 and a feeding culture 8 is carried out by adding baits by aeration. In this case, excrement 9 and residual baits 10 precipitate and are led by a lower water-discharge pipe 11 of the water tank to be decomposed into a nutrient salt solution 13 such as ammonia, nitrous acid, nitric acid or the like in a biological filter tank 13, a natural liquid organic fertilizer 18 is dissolved into an aeration 16 culture mat 17 and photosynthesis is accelerated in hydroponic culture species 15 and the aqueous solution increased in dissolved oxygen 9 is circulated in the fish culture tank through an antibacterial filter device 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] Industrial applications: Tilapia, Korosoma, Koi, Funa. A non-medicated aquaculture and organic pesticide-free organic hydroponic cultivation system that combines the cultivation of freshwater fish and shellfish such as rainbow trout and clamfish with the hydroponic cultivation of tomatoes, leeks, lettuce, komatsuna and herbs.

2. Description of the Related Art Conventional freshwater culture and hydroponic culture are performed separately and independently. Therefore, freshwater culture requires ammonia, nitrous acid, nitric acid, dissolved oxygen, dissolved oxygen, High cost and administration such as medication were issues. In addition, hydroponic cultivation is costly due to the cost of fertilizers such as nitrogen and phosphoric acid. On the other hand, freshwater aquaculture often uses antibacterial agents and antibiotics due to the occurrence of fish diseases. Was often used.

Problems to be Solved by the Invention Conventionally, freshwater cultivation and hydroponic cultivation have been performed independently and independently. However, by systemizing both, aquatic animals, plants, bacteria, and the environment are integrated. The aim is to maintain a sustainable ecosystem and achieve non-medicated aquaculture and pesticide-free organic hydroponics.

Means for solving the problems By injecting and adding a nutrient salt solution to conventional water and feed, the activation of fish is enhanced, the number of suitable aquaculture is strictly adhered to, and the occurrence of fish disease is prevented. By combining ammonia, nitrous acid, nitric acid, etc. from the decomposition of feces and remaining bait with hydroponic cultivation and a circulating complex system, the nitrogen,
Fertilizer costs such as phosphoric acid can be controlled at low cost. Moreover, pesticide-free organic hydroponics can be realized by using these solutions for hydroponics.

Action Fish farm tank (2) containing freshwater fish (1) in the house
In addition, the nutrient solution (6) is automatically added from the water supply tank (3) and the water temperature control boiler (4) to the water (5) at a constant temperature, and the feed culture (8) is also added to the feed while aeration (7). ). At that time, feces (9) and remaining bait (10) settle, and from the lower drainage tank (11),
Guided by the circulation pump (12), the biological filtration tank (1
In 3), a nutrient solution such as ammonia, nitrous acid and nitric acid (1)
The natural liquid organic fertilizer (18) dissolves in the hydroponically cultivated species (15) into the aerated (16) cultivation mat (17) to promote photosynthesis and dissolved oxygen (19). This is a house-type freshwater fish and shellfish non-medicated aquaculture and pesticide-free organic hydroponic cultivation circulation system in which an aqueous solution having an increased amount is circulated through an antibacterial filtration device (20) to a fish culture tank.

Effect of the Invention Freshwater cultivation and hydroponic cultivation up to now have been performed independently of each other, but by systematizing both, food production such as cultivation of animal proteins and institutional plants on a small amount of land is performed. Help.

[0007] By using the present invention, marine animals
An ecosystem integrating plants, bacteria and the environment is sustained,
Non-medicated aquaculture and pesticide-free organic hydroponics have reached a feasible stage.

The combined use of freshwater aquaculture and hydroponics makes effective use of ammonia, nitrite, and nitric acid by decomposing feces and remaining food, which have been issues of aquaculture, and supplies dissolved oxygen to increase the growth of fish and shellfish. It will be promoted and the cost of aquaculture facilities and management will be reduced.

[0009] By the combined system of freshwater culture and hydroponics, nitrogen and phosphoric acid necessary for hydroponics are supplied from freshwater culture and fertilizer costs can be reduced. In addition, carbon dioxide necessary for photosynthesis is also supplied to promote cultivation.

[0010] Since it is agriculture and fishery production using sunlight, it is energy saving and low cost.

[0011] Since it is a combined system of freshwater culture and hydroponic cultivation using an unused space in the same facility, productivity can be increased.

[0012] Since it is organic pesticide-free cultivation to which a nutrient solution is added, the growth is fast and the sugar content of tomatoes and the like is high.

[0013] By using the present invention, freshwater seafood such as tilapia, korosoma, koi, funa, rainbow trout,
The cultivation of clams, etc. can be done, and the hydroponic culture can include tomatoes, leeks, lettuce, komatsuna and herbs.
