Culture methods of water flea

Water flea refers to two kinds of zooplankton, aquatic cladocera and flexopod, which are nutritious and easy to digest, so they are palatable bait for Loach seedlings and Loach species. Artificial cultivation of water fleas to feed Loach with low cost, fast growth of loaches, and good effect of increasing production. Today, the editor of Qiannong Network will introduce the breeding methods of water fleas for everyone.

Build a pool

Soil ponds and cement ponds are available. The depth of the pool is about 1 meter, and the appropriate size is a rectangle of 10 square meters to 30 square meters.

Water injection

The depth of water injection in the pool is about 50 cm. The suitable water temperature of the water flea is 18 ℃ ~ 25 ℃, the ph is 7.5-8, and the dissolved oxygen saturation is 70%-120%.

Fertilizer application

Every cubic meter of water in the soil pond, 4 kg of cattle, horse dung or other animal dung, 1.5 kg of rice straw, wheat straw or other non-toxic plant stems and leaves are used as base fertilizer, and once after 10 days, the amount of topdressing is the same as the base fertilizer, and then according to the water color, the water color is kept yellowish brown. The cement pond puts 1.5 kg of cattle, horse dung or other animal manure per cubic meter of water, 1.5 kg ~ 2 kg of fertile soil, and then topdressing every 8 days, the amount of topdressing is 0.75 kg of cattle, horse manure or other livestock manure.

Cultivate

Whether it is soil pond or mud pond, the mixed culture method of yeast and inorganic fertilizer can be used. 20 grams of yeast per cubic meter of water, the yeast can be soaked in water for 3 to 4 hours, and then poured into the pond. 65 grams of ammonium carbonate and 37.5 grams of ammonium nitrate are applied per cubic meter of water, and then every 5 days, the dosage is half of the beginning. After adding yeast and exposing the pond water for 1 ~ 3 days, you can put water fleas as seeds, with a seed amount of 30 ~ 50 grams per cubic meter of water.

Pick up

After being planted in the pond for 15 ~ 20 days, the water flea can be spread all over the pond after mass reproduction. At this time, can be fished in batches to feed Loach. Generally, it is harvested every 1 to 2 days, accounting for 10% or 20% of the total amount. When the water temperature is 18 ℃ ~ 20 ℃, it can be caught frequently and continuously.
