Problems solved by technology

At present, there is no research report on the growth of cockles with different sizes during the breeding period in China. In fact, different stocking sizes have a greater impact on the culture of cockles. Only cockles within a certain size range have the largest relative growth and the highest survival rate during the breeding period.

Embodiment 1

[0021] Effects of different specifications of cockles on growth: At the beginning of April, the bottom soil of pond cockles was plowed, exposed to the sun for 8 days, smoothed with water, and disinfected at a rate of 1.5 kg / 667m 2 Sprinkle bio-fertilizer and water at a certain ratio to fertilize water, fertilize single-celled algae in the water, and control the density of single-celled algae in the clam field to more than 10,000 to 12,000 c / ml. Set up 6 areas in the clam field, each with an area of ​​20m×10m, and divide the cockle seedlings into six areas according to the six specifications of 4.2mm, 5.2mm, 6.4mm, 8.2mm, 11.6mm and 21.4mm. Density: 500 grains / m 2 . The implementation of manual even broadcasting for breeding. In the middle and late April, stocking 0.9cm long Penaeus japonicus seedlings, the input amount is 7,000 tails / 667m 2 . In June, the barracuda seedlings were put into use, and the input amount was 200-350 fish / 667m 2 ;Put in adult white shrimp or seed...

Embodiment 2

[0034] Selecting 2.67hm of cockle ecological breeding ponds in the Yellow River Delta 2 , of which the cockle field area is 4000m 2In mid-March, plow the cockle field, expose it to the sea for 10 days, and smooth it out with seawater. The seawater is filtered through a 60-mesh silk screen to remove predators. You can sprinkle tea cakes in the deep water of the pond to kill harmful fish such as shrimp and fish. . In the first ten days of April, every 1.5 kg / 667m 2 Apply biological fertilizer and water. On April 18th, the cockles were stocked, the stocking size was 21.4mm, and the stocking amount of cockles was controlled to be 500 grains / m 2 . On April 26, stocking of Penaeus japonicus fry, the stocking volume is about 10,000 tails / 667m 2 , when the length of Penaeus japonicus reaches about 5cm, start feeding Artemia adults, and feed about 125kg per day, when the length of Penaeus japonicus grows to about 8.3cm, start feeding smooth blue clams, and start fishing for Penaeu...

Embodiment 3

[0051] Water quality biological control technology, including the following steps:

[0052] a) Purification effect of bait algae on water quality: select 3 algae species of Chaetoceros mouvii, Flatweed, and Dunaliella for cultivation and expansion, take samples every 2 days, and measure pH, salinity, and COD Mn , total nitrogen, total phosphorus, algae density;

[0053] b) Effect of shrimp and shellfish ecological cultivation on water purification: the cultivation process is the same as in Example 1, and the detection and analysis indicators are the same as c;

[0054] c) The effect of bio-improvement agents on water quality purification: In 4 Erlenmeyer flasks, add bio-aeration granules, 5ppm, and 10ppm of high-efficiency biological agents, respectively, add 50ml of Chaetoceros moubii algae liquid, take the supernatant regularly, and measure PH, COD, BOD5, nitrite nitrogen, total nitrogen, total phosphorus content;

[0055] d) According to the above test results, use high-e...

Abstract

The invention belongs to the field of aquiculture, and in particular relates to an ecological cultivation method of the arca subcrenata lischke. The method comprises the steps of: treating the arca subcrenata lischke, stocking the arca subcrenata lischke, cultivating the arca subcrenata lischke in a covering way, adjusting the water quality, measuring in a sampling way, and controlling the disease. The arca subcrenata lischke is stocked according to six specifications such as the 4.2mm, 5.2mm, 6.4mm, 8.2mm, 11.6mm and 21.4mm, the stocking density is 450-550 granules / m<2>, and the growing condition of the six groups of the arca subcrenata lischke is compared with the surviving condition of the six groups of the arca subcrenata lischke. The method has the benefic effects that the stocking specification is reasonable by adopting the ecological cultivation method, the water quality is purified, the sewage discharge is reduced, the ecological environment is protected, the quality of the aquatic product is guaranteed by the three-dimensional ecological cultivation of the arca subcrenata lischke with the penaeus japonicus bate, the palaemon carinicauda and the barracuda, and the economic benefit is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological breeding method for cockles. Background technique [0002] Cockles, belonging to the mollusk phylum, commonly known as "ma cockles", grow in soft muddy or sandy seabeds in shallow seas. Their meat is delicious and rich in vitamin B 12 And bioactive substances, have high edible and medicinal value, and have broad market application prospects. In recent years, due to many reasons such as environmental pollution and overfishing, the cockle resource has been greatly damaged, its sea catch production has been decreasing year by year, and the natural resources are almost exhausted, while the artificial breeding and artificial breeding of cockles are still in the initial stage of experimentation. [0003] In recent years, researches on the biology and breeding of cockles have been carried out successively in coastal areas. Shen Weiliang et al. studied the...
