Embodiment 1

[0023] Example 1 Beneficial microorganisms research on the purification effect of aquaculture water

[0024] Based on the research on the culture conditions of photosynthetic bacteria, bacillus, nitrifying bacteria, etc., culture and make single bacteria liquid or composite bacteria liquid (photosynthetic bacteria Rhodopseudomonas palustris, Bacillus subtilis, Nitrosomonas) The water quality purification experiment of Penaeus vannamei aquaculture water body. The medium formula used is: 2.00g of ammonium chloride, 0.20g of dipotassium hydrogen phosphate, 4.00g of sodium acetate, 2.00g of sodium bicarbonate, 1.00g of sodium chloride, 0.15g of yeast extract, 0.20g of magnesium sulfate, and 1000mL of distilled water. Inoculate the above-mentioned bacterial species into the culture medium alone or in combination, cultivate and make a single bacterium solution (OD600 greater than 1) or a composite bacterium solution (photosynthetic bacteria Rhodopseudomonas palustris, Bacillus and ...

Embodiment 2

[0040] Embodiment 2 floating bed plant is to the purification test of aquaculture water

[0041] The experiment selects the 5L plastic oil bottle with the mouth of the bottle cut off as the culture container, and each bottle holds 3 kg of pond water. The pond water has been tested for total nitrogen (TN), total phosphorus (TP), ammonium nitrogen (NH4 + -N), chemical oxygen demand (COD Cr ) were 4.54mg / L, 0.59mg / L, 1.03mg / L, 53mg / L, respectively.

[0042] The experiment was conducted in an experimental group and a control group. In the experimental group, one plant was planted in each bottle, and 2 bottles of each plant were planted. In the control group, no aquatic plants were planted. The test period was 15 days. The test started in early August, measured the temperature, water temperature and observed the morphological changes of the plants every day, took water samples every 10 days, and measured TN, TP, NH4 + -N, COD Cr Water quality indicators, and regular replenishmen...

Embodiment 5

[0076] Example 5 Popularization and Demonstration of Penaeus vannamei Ecological Breeding Method

[0077] Demonstration and promotion of water quality control of Penaeus vannamei aquaculture. The water quality control measures in the demonstration ponds are the same as in Example 4 except that bighead carp is not stocked and soft-shelled turtles are replaced with eels. Breeding mode: Stocking desalinated Penaeus vannamei seedlings in May, nesting eels and silver carp, supporting bottom aeration, water plowing machines, and planting aquatic plants water spinach (configured at a ratio of 2%, planting water spinach 13m per acre) 2 ), combined with the application of microbial preparations (according to 3g / m 3 The ratio of splashing once every 15 days) and other measures to adjust the water quality, and in July and August, the big ones were caught and the small ones were listed.

[0078] Benefits: The demonstration area of ​​Penaeus vannamei is 285 mu. The average yield per mu of...

Abstract

The invention provides a pond eco-culture method for prawns. The method comprises the steps: on the basis of culturing the prawns in a pond, raising at least one kind of aristichthys nobilis, Hypophthalmichthys molitrix, eels, soft-shelled turtles, hemibarbus maculates, pelteobagrus fulvidraco and xenocyprininae; in a culture cycle, adding a composite microbial preparation to a water area of the pond at the interval of 5-30 days according to the ratio of 1-15g/m<3>, wherein the composite microbial preparation contains photosynthetic bacteria, bacillus and nitrobacteria; and meanwhile, arranging a water plowing machine for the culture pond, so as to improve the uniformity and replenishment capacity of dissolved oxygen of water. According to the pond eco-culture method, by an ecological regulating and controlling technology, the reasonable conversion of organic remnant bait and excrement is promoted, and the yield and quality of culture of the prawns are improved.

Description

technical field [0001] The invention relates to the technical field of aquatic ecological cultivation, in particular to a pond ecological cultivation technology of Penaeus vannamei. Background technique [0002] Aquaculture has become the main growth point of my country's fishery development, and occupies an increasingly important position in my country's national economy, especially in the development of agricultural economy. The vigorous development of the aquaculture industry can not only ensure the supply of high-quality protein, enrich the "vegetable basket", stabilize prices, and promote social harmony and stability; it also makes it possible for the reasonable proliferation of fishery resources in natural waters, and while ensuring the income of fish farmers, avoid fishery Excessive consumption of resources is of great significance for building a livable environment. [0003] In recent years, with the continuous development of shrimp farming technology, the vannamei ...
