Abstract

The invention provides a water flea collecting device for indoor culture based on microalga. The water flea collecting device comprises a water flea collecting device, a water inlet and a water inlet valve which are arranged at a water inlet port of the water flea collecting device as well as a water flea trapping lamp and a water flea collecting port which are arranged on the side wall of the water flea collecting device, wherein a water flea collecting valve is arranged on a pipeline of the water flea collecting port, a filtering device used for separating living water flea from stones, microalgae residues, water flea shells, excrement and suspended residue particles is arranged in the water flea collecting device, a water outlet is formed in the bottom of the water flea collecting device, and a water outlet valve is installed on a pipeline of the water outlet; and the water flea collecting device is supported and fixed by supporting footstands. The device does not damage the water flea, is high in safety, can quickly separate the water flea from inactive residues and remove the residues, and is high in removal rate and good in effect.

Description

technical field [0001] The invention relates to the technical field of water flea collection, in particular to a water flea collection device based on microalgae for indoor cultivation. Background technique [0002] In natural water bodies, after fry hatch from fertilized eggs, they mainly feed on zooplankton, and also feed on phytoplankton (such as algae), especially rotifers and some small species of cladocerans. As a high-quality bait for fry, zooplankton has an absolute advantage that artificial feed cannot replace. [0003] Daphnia sinensis is one of the most important species of zooplankton in the Yellow Sea and the East China Sea. The distribution range of the population is very wide, from the inland sea of ​​Japan to the coastal waters of Vietnam. When the number is the highest, it can account for more than 80% of the total biomass of zooplankton. It is Eggs and nauplii are the main food for species at a trophic level in the food chain. [0004] Copepods mainly fee...
