Usage of CarbonFiber to the sea culture and culture with a tank
■To make livable environment for fish by MiraCarbon!!
When water quality gets worse by overfeeding and waste matter in culture
for marine products, it might cause to be sickness and infectious disease.
Moreover, unlike culture in a tank, culture in the sea is influenced by
open sea and river water. In case of red tide, poor oxygen, and bottom
sediment in eutrophicated ocean area, culture's environment gets worse
MiraCarbon forms activated biofilm due to its high bioaffinity, and then
pollutants are caught and decomposed by the action of the microorganism.
Without any negative impact on ecological system, it makes good habitats
for fish and aquatic livings. Moreover, It works as seaweed bed for places
where to lay eggs and to bring up young fishes.
|Problems of marine product cultivation
■Water quality improvement
The advantages of using CarbonFiber
CarbonFiber adsorbs polluted substance, and water quality and bottom
sediment are improved by decomposition.
Nutrient salts are reduced and eutrophication is controlled.
It is safe due to small environmental impact.
■Increase of marine products
Disease and death of fish decrease due to improvement of water quality.
The number of catches of fish is also expected to increase.
Growth of fish is facilitated due to improvement of water quality. Quality
and safety improve.
■Reduction of the cost
Can expect the reduction of the amount of antibiotics by improvement
of water quality.
Can use CarbonFiber for long term because it does not go rotten and
Can save time to change water because the water is kept as clean for
Water purification in a tank of cultivation and culture farm
・Water purification in inner bay (sea area) ・Water purification in tank
Sea cultivation and Cultivation in a tank
・The spawning place ・Raising place for young fish ・Seed bed ・Seaweed
It is important to understand installation site condition.
Especially, the condition of the sea culture changes more than the condition
of inland body of water.
It is necessary to choose a certain installation method under various conditions.
The main considering points of installation are as follows.
■Topography Submarine topography, bottom sediment (sludge), closed water
area, water depth
■Current Tide, stream, river inflow, existence or non-existence of
■Environment Fish's lifestyle (planetism, benthic), the size of culture,
shape of facility
Construction Example 1: In the sea
This method is to purify seawater. CarbonFiber is attached to a fish-preserve
By installing a fish-preserve raft in enclosed bay, purification effects
It is also used for supporting places for fishes.
Construction Example 2: In a tank
This is a method to install CarbonFiber to the purification plant, then
after purifying water, it is back to the tank.
Efficiency of water purification is improved by separating purification
plant from the culture tank. This method is valid for the tank which can
not install CarbonFiber.
Construction Example 3: In a tank
This method is to install CarbonFiber to the culture tank and purify water
in the tank.
It is enable to install CarbonFiber to the existing tank. Changing place
of CarbonFiber depends on kind of fish is expected as a function of seaweed
bed and purifying pollutant in the bottom of tank.
