Problems solved by technology

Farmers often over-fertilize in order to pursue growth speed, which not only pollutes the aquaculture water, but also contains a large number of pathogenic bacteria in the organic fertilizer, which makes the pearl oyster disease occur frequently, seriously affecting the breeding efficiency and ecological environment
Due to the pollution of the breeding environment caused by excessive fertilization, some local governments had to impose "restriction orders" on the cultivation of freshwater pearl mussels

Embodiment 1

[0025] 1. On May 15, 2015, fished fresh Elodea from the crab breeding pond, cleaned the root silt and impurities, drained for 10 minutes, and weighed.

[0026] 2. Place 6 200L plastic buckets outdoors, add 5kg of Elodea, add 25kg of tap water to aquatic plants and water at a weight ratio of 1:5, and mark it as group A, add 40kg of tap water at a weight ratio of 1:8, and mark it as group B ; Set 3 repetitions for each group.

[0027] 3. The plastic bucket is covered and sealed to avoid light. After 3 days, all the aquatic plants will rot. Open the sealed cover and stir the fermentation liquid every day to keep natural light.

[0028] 4. The temperature was measured in the morning and evening. After cultivation until May 30, the average temperature for 15 days was 25.8°C, and the accumulated temperature was 387°C d. Checking under the microscope, the dominant species of algae were diatoms and cryptophytes, and the average concentration of algae in group A was 1.77×10 10 indivi...

Embodiment 2

[0031] 1. On July 20, 2015, fished fresh Elodea from the crab breeding pond, cleaned the root silt and impurities, drained for 30 minutes, and weighed;

[0032] 2. Place 6 200L plastic buckets outdoors, add 5kg of Elodea, add 25kg of river water to aquatic plants and water at a weight ratio of 1:5, and mark it as group A, add 40kg of river water at a weight ratio of 1:8, and mark it as group B . Each set has 3 repetitions.

[0033] 3. Put a cover on the plastic bucket and seal it away from light. After 2 days, all the aquatic plants will rot. Open the seal cover and stir the fermentation liquid every day to keep the natural light.

[0034] 4. Measure the temperature in the morning and evening. After cultivating until July 30, the average temperature for 10 days is 32.9°C, and the accumulated temperature is 329°C d. Checking under the microscope, the dominant species of algae are diatoms and cryptophytes, and the average concentration of algae in group A is 1.63×10 10 indivi...

Embodiment 3

[0037] 1. On September 1, 2015, fished fresh hay from the crab breeding pond, cleaned the root silt and impurities, drained for 20 minutes, and weighed;

[0038] 2. Place 6 200L plastic buckets outdoors, add 5kg of bitter grass respectively, add 25kg of river water to aquatic plants and water at a weight ratio of 1:5, and mark it as group A, add 40kg of river water at a weight ratio of 1:8, and mark it as group B. Each set has 3 repetitions.

[0039] 3. Cover the plastic bucket and seal it to avoid light. After 3 days, all the aquatic plants will rot. Open the sealed cover and stir the fermentation liquid every day to keep the natural light.

[0040] 4. Measure the temperature in the morning and evening. After cultivating until September 19, the average temperature for 18 days is 24.3°C, and the accumulated temperature is 437.4°C·d. Checking under the microscope, the dominant species of algae are diatoms and cryptophytes, and the average concentration of algae in group A is 1...

Abstract

The invention relates to a potamilus alatus palatable bait large-scale cultivation and collection method, and an application thereof, and belongs to the technical field of aquaculture. Fresh aquatic plants are selected, and drained and weighted, the aquatic plants and water are subjected to normal temperature fermentation processing, the accumulated temperature is measured and calculated, dominant species and number of algae are obtained through microscopic examination, after two-times filtration, high speed centrifugation and cold preservation are carries out, then potamilus alatus palatable bait is obtained. The invention provides a potamilus alatus palatable bait large-scale cultivation and collection method which is low in cost and high in concentration, and is simple and practical, and an application thereof, many kinds of algae are cultured, and the algae have comprehensive nutrition, and do not pollute the water environment, the cultivation survival rate and the growth rate of the potamilus alatus can be substantially increased, the industrialization development process of China fresh water purple black pearl culture can be accelerated.

Description

technical field [0001] The invention relates to a method for large-scale cultivation and collection of palatable bait for purple black clam and its application, belonging to the technical field of aquaculture. Background technique [0002] Purple black clam ( Potamilus alatus ), also known as purple-heeled mussels, winged brook mussels, mainly distributed in the Mississippi River, Great Lakes, Gulf of Mexico and other watersheds in the United States. It is a large freshwater shellfish. The adult shellfish is more than 20cm long. , very shiny. Huadan's pearl breeding experiment shows that the Zihei pterosaur is an excellent variety for cultivating freshwater Zihei pearls. In order to develop my country's freshwater purple black pearl breeding industry, in 2012, the Freshwater Fishery Research Center introduced the world's first batch of artificially bred purple black clam seedlings from the United States. Zihei clam belongs to stream shellfish. Although its shape has some ...
