Abstract

The invention provides a high-yield and stable-yield intensive cultivation method for cladocera. The high-yield and stable-yield intensive cultivation method comprises the following steps: (1) selecting a cement cultivation pond with an area of more than or equal to 65 m<2>, and arranging two fertilizer ponds in a matched manner; (2) applying a compound fertilizer to the fertilizer ponds, simultaneously injecting 30-50% of clean water and 50-70% of compound fertilizer water into the cement cultivation pond in a convection manner, applying the compound fertilizer, and applying biogas slurry every day; (3) inoculating the cladocera into the cement cultivation pond, carrying out inoculating for 1-2 days, applying the biogas slurry every day, carrying out inoculating for 3-5 days, feeding a bait with an amount of 0.1-0.3 g / m<2> every day, carrying out inoculating for 5-7 days, then draining 15-25% of pond water into the cement cultivation pond every 3-5 days, injecting 30-35% of clean water and 65-70% of the compound fertilizer water which are equal in amount into the cement cultivation pond, and applying the compound fertilizer; and (4) carrying out fishing and cleaning. The high-yield and stable-yield intensive cultivation method provided by the invention effectively maintains the dynamic fluidity of the fertility of a water body, improves the quality of the water body, guarantees the stability of the yield of the cladocera, and achieves stable and high-yield intensive cultivation of the cladocera.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield and stable-yield intensive cultivation method of Cladocera. Background technique [0002] Cladocera (Cladocera) is also referred to as "water flea, daphnia class". The body is short and oblong, divided into head and body, with flattened sides and indistinct body segments. Most of them live in fresh water, ponds, lakes, and rivers, and are important bait for fish, so they are commonly called "fish insects". Cladocera is not only high in protein, rich in important amino acids needed by fish, but also rich in vitamins and calcium, which is an ideal opening bait for raising fish, shrimp and crab larvae. As the amount of Cladocera used as high-quality bait is increasing, the existing Cladocera cultivation technology is far from reaching the supply density required by the market. At present, in the process of Cladocera cultivation, it is often difficult to control wa...
