Description
Technical field
The present invention relates to technical field of aquaculture, and in particular to a kind of improver of water quality used for aquiculture.
Background technology
Breed fish and first support water, good water has supported fish, and with developing rapidly for China's aquaculture, cultivation density is continued to increase, one
A little breeding water body water quality and substrate serious aging, with the growth of cultivation phase, the organic matter in pond is more and more, with water temperature
Rise, constantly bait throwing in whole process, fish constantly ingest, constantly drain, and the algae in water constantly grows, extremely
Die.Cultivation density is too high, causes and feeds excessively, substantial amounts of residual bait, excrement, excreta diffusion dissolution neutralize in water and be deposited on water
Bottom, unnecessary feed, fishes and shrimps excreta, dead algae also has corpse of some other animals and plants etc. to be accumulated all in water, cultivates
Carry out day by day, these materials are just accumulated day by day, etc. total amount accumulation to a certain extent, cause the pH value of water body to change, water body
Ammonia nitrogen, content of nitrite rise, and water transparency declines, and the variation of organic matter amount reproduction and algae phase, water quality integrally deteriorates,
Bacterial pathogens grow.
For the continuous worsening of aquatic environment, the index such as ammonia nitrogen, nitrite, dissolved oxygen amount in water body, which is difficult to regulation and control, to be caused
Fish disease take place frequently, aquaculture family largely use medical treatment, but water in addition medicine after, it may appear that precipitation, layering, discoloration,
The phenomenons such as muddiness, cause drug effect to reduce or lose, while can also accelerate the deterioration of water quality situation, produce secondary pollution, further
Fish meat is had a negative impact again, vicious circle is formd, great is influenceed on culture fishery.
The content of the invention
For above-mentioned problem, the present invention proposes a kind of improver of water quality used for aquiculture, by reasonably matching somebody with somebody
Fang Zucheng, is improved from biochemical, physics and chemistry many aspects to water quality, with excellent absorption, degraded, the effect purified, simultaneously
Certain nutriment can be provided, the cultivation efficiency of aquatic biological is effectively increased.
In order to realize above-mentioned purpose, the present invention uses following technical scheme:A kind of improver of water quality used for aquiculture,
It is characterised in that it includes following parts by weight component is made:It is 23-28 parts of mineral powder, 2-4 parts of bactericide, 6-10 parts of biological bacteria, net
