Description

Fresh water culture device for high-density post-seedling soil pond culture

Technical Field

The utility model belongs to the technical field of aquaculture, concretely relates to big fresh water culture device is supported in high density mark post-emergence pond.

Background

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. Generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management. The method can also be used for the proliferation of aquatic resources in a broad sense, and aquaculture can be realized by means of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods.

The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density fish culture, shrimp culture and the like. Water is an environmental condition for survival and growth of aquatic products, and the quality of water quality directly influences the culture yield. How to adjust the water quality and promote the quick and healthy growth of aquatic products is a problem which always troubles farmers. In the whole culture process, the key and difficult point of the water product technology is to build good and stable water quality. The aquatic product culture is a pollution process, in the middle and later stages of pond culture, the aquatic products are mainly fed with artificial compound feed, residual baits and excrement of the aquatic products are continuously accumulated, animal and plant corpses are continuously increased, the residual baits, the excrement and the animal and plant corpses are deposited at the bottom of a pond to be subjected to anaerobic decomposition, a large amount of harmful substances are generated, water quality and substrate are spoiled, and the culture environment is deteriorated, and the process is mainly characterized in that: 1. the biological oxidation and decomposition at the bottom of the pool consumes a large amount of oxygen, so that aquatic products are in a low-oxygen environment, and the physique and disease resistance of the aquatic products are reduced; 2. excessive nutrition remains, and a large amount of facultative anaerobes decompose organic substances in a low-oxygen environment to generate a large amount of intermediate products such as ammonia nitrogen, nitrite, hydrogen sulfide, organic acid and the like, so that serious toxic effects on aquatic products are caused; 3. excessive nutrition in the bottom mud is released, so that water eutrophication is caused, meanwhile, trace nutrients such as calcium, magnesium, iron, manganese and the like are deposited on the bottom mud in the form of insoluble salt and are difficult to release due to acidification at the bottom, so that nutrition imbalance is caused, the growth of beneficial algae is inhibited, and the blue algae, dinoflagellate and the like which like abundant nutrition become dominant species, so that the water quality is deteriorated; 4. the environment with low oxygen and high nutrition enables pathogenic bacteria such as vibrio and the like to be rapidly propagated, so that diseases and even death of aquatic products occur. At present, the purpose of regulating and controlling the water quality of aquatic product culture is to reduce organic matters in a water body, and further reduce the biological oxygen consumption and the nutrient balance of a pond. The improvement of dissolved oxygen can inhibit the propagation of anaerobic bacteria such as vibrio, simultaneously reduce the accumulation of reductive toxic substances, inhibit the growth of blue-green algae and dinoflagellate, facilitate the growth of beneficial algae such as green algae and diatom, stabilize bacterial phase and algal phase and improve the disease resistance of aquatic products. The existing water quality regulation and control methods for aquatic product pond culture mainly comprise three water quality regulation and control methods of a physical method, a chemical method and a biological method, wherein the biological method is commonly used, but the methods have high treatment cost, low success rate, poor operability or insignificant effect. The most commonly used method for regulating and controlling the water quality of the pond culture of aquatic products is the algae bacteria regulating and controlling technology, which degrades and converts culture metabolites and residual baits through the combined action of floating microalgae and beneficial bacteria, regulates the water quality, inhibits the breeding of harmful bacteria and harmful microorganisms, and creates an ecological environment suitable for the growth of aquatic products. The main technical scheme is as follows: selecting the weather with sufficient sunlight, putting inorganic composite nutrients, organic composite nutrients and trace elements with good solubility and proper proportion into the pond, and culturing beneficial microalgae; regularly and uniformly putting bacillus into the pond in the culture process, putting photosynthetic bacteria, lactic acid bacteria and the like according to the water quality condition, and keeping the dominant ecological niche of the beneficial bacteria in the pond; and the molasses is used for supplementing a carbon source in the middle and later stages of cultivation, so that the stability of a bacterial phase and an algae phase is promoted. However, the stability of the phycomycete regulation and control technology is poor, and common farmers are difficult to master; during algae cultivation, most of the matched nutrients thrown into the pond are agricultural fertilizers, so that the agricultural fertilizers are difficult to uniformly spread, only a small part of the nutrients are utilized by the algae, and most of the nutrients are absorbed by bottom mud, so that more organic matters are generated at the bottom of the pond, the deterioration of the bottom is caused, and the excessive propagation of harmful algae such as blue algae is easily caused; the microalgae population structure in the pond is easy to change along with the change of environmental conditions, and the 'algae phase' is unstable; when beneficial bacteria and photosynthetic bacteria are put into the pond, most organic matters to be degraded are positioned at the bottom of the pond and are not uniformly distributed, and fungi cannot be purposefully scattered to a target substrate, so that resources are wasted; the lactobacillus belongs to anaerobic bacteria, and the activity of the lactobacillus in the upper layer of the water body, particularly in oxygen-enriched areas such as the vicinity of an aerator and the like, is greatly reduced; the photosynthetic bacteria lack substrates for decomposition when in the upper layer of water, and cannot play a role because of insufficient light when the bottom of the pool is close to the substrates; in addition, some microorganisms such as bacillus consume oxygen seriously in the nitrification process, dissolved oxygen in a water body can be consumed directly in the pond, the growth of water products is not facilitated, meanwhile, the labor cost is increased, the requirement for industrial culture is high, and people require the intellectualization of culture.
