Description

Flocculant production agent
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a flocculant production agent.
Background
With the intensive high-density aquaculture in China, a large amount of waste, residual bait, animal and plant residues and the like are continuously accumulated in aquaculture water bodies and the bottom of a pond, so that the water quality is deteriorated, the structure of an ecological system is damaged, the biodiversity is damaged, and the fish and the shrimp are restricted in ingestion and growth, even are ill, poisoned or dead. The chemical drugs are used periodically, so that the water quality is worsened, and the quality safety of aquatic products is influenced. The traditional fishery predatory breeding water area has long-term ecological benefit and environmental benefit, becomes a key factor for restricting the healthy and continuous development of the aquaculture industry, and makes a discussion on a brand-new concept of ecological breeding mode imperative. At present, the water environment of a pond is mainly adjusted by adding new water and adding a microecological preparation or a carbon source, the water quality indexes such as ammonia nitrogen, nitrite and the like in the water environment can be improved after the water environment is used, the improvement degree is limited, and meanwhile, no influence report on the concentration of sulfides in the water is found. The toxicity of the sulfide mainly refers to the toxicity of hydrogen sulfide, and the hydrogen sulfide is a soluble gas with the odor of a smelly egg and is a highly toxic substance harmful to aquatic animals. The sulfide can enter tissues and blood of fishes, shrimps and crabs through permeation and absorption, the structure of heme is destroyed, and the hemoglobin loses the capability of combining oxygen molecules; meanwhile, the fish mask has strong stimulation and corrosion effects on the skin and mucous membrane of fish, so that tissue generates coagulation necrosis to cause dyspnea and even death.

Example 8
The yellow river carps used in the experiment are domesticated, good food intake is realized in an indoor aquarium with sufficient illumination, and fingerlings with strong physique and uniform specification are selected for the experiment. The feeding experiment period is 8 weeks, the experiment is divided into a control group, an experiment 5 group, an experiment 6 group and an experiment 7 group, each group is provided with 3 replicates, and 150 fish tails are placed in each group. The control group was fed with no other substances than the normal feed. In addition to normal feed feeding, the flocculant produced in example 5, example 6 and comparative example 2 were added to the test 5, test 6 and test 7, respectively, in an amount of 8kg/667m3. Mixing the carbon source with aerated water, mixing with a microbial preparation, an amino acid fertilizer, vitamin C phosphate and mannan oligosaccharide, and performing closed fermentation for 2-3 d to obtain a fermentation product; mixing baking soda, calcium superphosphate, plant extract and aerated water to obtain mixture; and after the mixture and the fermented product are mixed, uniformly splashing the mixture in the morning on a sunny day. Meanwhile, the oxygen increasing equipment is required to be started to ensure that the dissolved oxygen is not less than 4mg/L all day.
During the test period, the feeding is normally carried out, water is not changed, and the lost water is supplemented by tap water subjected to aeration and temperature regulation at regular intervals. The results are shown in tables 3 and 4.
