Abstract

The invention discloses an ecological culture method of bait for brevifilis fry. The method comprises the following steps: A, constructing a bait pond; B, disinfecting the bait pond; C, applying fertilizer, namely, applying 8 to 12kg of special fishing fertilizer at every 667m<3>, and then compensating 8 to 12g of urea and 0.4 to 0.6g of superphosphate at each cubic meter in every two weeks; D, introducing young water earthworm, namely, draining water from the bait pond in March, uniformly spreading young water earthworm based on the standard of 0.4 to 0.6kg / m<2> to the bottom of the bait pond, and then adding water being 5cm in depth to cover the young water earthworm; E, ecologically managing, namely, adding 47-53kg of snails at every 667m<2> to control the water quality, and overturning the pond once through a rake at every 15 days; F, daily managing; and G, collecting once every 30 days at night, namely, adding cold water to the bait pond, irradiating through light to attract water earthworm to gather, and then collecting through a mesh bag formed by 40-meshes polyethylene fiber mesh cloth.

Description

technical field [0001] The invention relates to the technical field of ecological cultivation, in particular to a method for ecological cultivation of bait for larvae with flap knots. Background technique [0002] The genus Osteophyta belongs to the class Osteophyta, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, genus Osteophyta, subgenus Osteophyta. Commonly known as: Hasi, Chongkou, Mazui, Laju. The valvefish is a middle-lower fish that lives in clear running water. It has a streamlined body shape, a pointed head, and strong fins. It is one of the fishes that are good at swimming. It often passes through the rocks at the bottom of the water, sucks food from the bottom of the river and the stone surface with its trumpet-shaped flexible mouth, and feeds on benthic molluscs, aquatic insects and their larvae, plant fragments and filamentous algae. In the larval stage, the lobed fish has a large mouth and mainly feeds on larger aquatic animals. When cultivating conventional ...
