In order to meet the rapidly increasing consumption of fishery, fishing has been transformed into a fishery that has been bred from traditional catch fishing all over the world.

When the water temperature in freshwater fish farms rises above 30 ° C during the warmer summer due to global warming, there is a problem that freshwater fish do not eat feed to avoid the heat, resulting in slow growth and shipment time, resulting in feed and labor costs. As it led to the addition of water temperature needed to be lowered.

On the other hand, in the case of freshwater fish, when the water temperature of the fish farm is lowered below a certain temperature, there is a problem that the fisheries industry must be stopped early in the fall because it prepares to enter hibernation without feeding.

In addition, although the supply of aquatic products has increased with the development of aquaculture, which is called aquaculture or fish farming, environmental and health problems are seriously raised.

Conventionally, aquaculture or fish farming is mainly performed in stagnant waters such as coastal waters, lakes, artificial fish farms, or aquaculture farms, and artificial feeds are frequently introduced in order to speed up the time of shipment by increasing the rate of growth of aquatic products. .

In this case, if the water quality is not purified, dissolved oxygen is depleted, so-called eutrophication may occur, and environmental problems may occur, as well as death of aquatic products.

As shown in FIG. 4, the larch (English name: Deciduous Cypress, scientific name: Taxodium distichum (L.) Rich.) Is a deciduous coniferous tree whose native origin is North America, and is conical in shape and its height is 20 to 50 m and its diameter is 2 to 5 m. As it is able to grow, it is attracting attention as a landscape tree, and its wood is used for railway sleepers, greenhouse materials, and roofing materials because of its strong durability.

Mangrove trees are a generic term for shrubs or arbors that live in the intertidal or muddy areas of tropical or subtropical coasts or parts of estuaries.

Larch or mangrove trees can grow in the water by adjusting the water level of the fish tank 10 because it generates an inferior respiratory muscle as shown in FIG. 5 in the place of poor drainage or fish farm (1).

In the case of freshwater fish, when the water temperature is 30 ℃ or higher, it avoids heat without feeding and thus delays shipping time, thereby increasing feed and labor costs. In addition, when the water temperature decreases from late autumn, the fishery is stopped because it prepares to hibernate without feeding.

Larch and mangrove trees provide shade in summer to prevent excessive increase in water temperature, thus preventing the increase of feed and labor costs due to the slow growth of marine products and the delayed shipping time, and deciduous leaves preserve underwater heat in late autumn and winter. On the other hand, the heat generated when rotting can increase the temperature of the fish, which can prolong fish farming.

In addition, the artificial feed is excessively absorbed through larch or mangrove tree roots are used as nourishment necessary for growth, thereby contributing to water purification.
