Abstract

The invention discloses a sturgeon fry bait ecologic cultivation method. The sturgeon fry bait ecologic cultivation method comprises steps of constructing a bait pool, performing disinfection on the bait pool, adopting exclusive guano to perform water fertilization five days after disinfection, wherein an application amount of the exclusive guano is 8-12kg/667m3, draining water in the bait pool every march, uniformly distributing water earthworm larvae on the bottom of the bait pool, putting water to cover the water earthworm larvae on the bottom of the bait pool, wherein the water depth of the bait pool is 3-6cm, the water depth in the bait pool during the day is 3-4cm and the water depth of the bait pool during the night is 5-6cm, performing water quality regulation, with regulation frequency being once in every 14-16 days, and capturing. The sturgeon fry bait ecologic cultivation method can promote the sturgeon fries to feed, improves growing speed of the sturgeon fries, improves immunity of the water earthworm, reduces pathogens carried by the living bodies of the sturgeon fries and reduces likelihood of having diseases.

Description

technical field [0001] The invention relates to the technical field of bait for young sturgeon, in particular to an ecological cultivation method for bait for young sturgeon. Background technique [0002] Water earthworms, also known as red filarial worms and red nematodes, belong to aquatic oligochaetes in annelids, and their body color is bright red or flesh red, orange yellow. They mostly live in the sewer sludge (generally in slow-flowing black sludge) that discharges sewage or waste water, and are densely packed on the surface of the sludge. One end is fixed in the sludge, and the other end protrudes from the sludge to vibrate in the water. , immediately retracted into the sludge. [0003] The nutritional value of water earthworms is extremely high, and they should be rinsed repeatedly in clean water before feeding. Water earthworms are often used as bait for larvae in aquaculture. Water earthworms will die in large numbers when they encounter strong light and high t...
