Background
In natural water, after hatching from fertilized eggs, fish fries mainly feed on zooplankton and also feed on phytoplankton (such as algae), in particular rotifers and small-sized species of cladocera. The zooplankton as high-quality bait for fry has the absolute advantage that artificial feed cannot replace the zooplankton.
The Chinese philosophila flea is one of the most main zooplankton species in yellow and east China sea, has wide population distribution range, is distributed from Japan inner sea to the offshore of Vietnam, can account for more than 80% of the total biomass of zooplankton when the number is the highest, and the eggs and nauplii of the Chinese philosophila flea are main baits of a nutrition grade species on a food chain.
Copepods are the main feed in nature for phytoplankton, especially diatoms. In addition, copepods also ingest feed for dinoflagellates, protozoa, debris and other zooplankton eggs and larvae which are critical to the reproductive activity of copepods, where egg production of copepods can be arrested in the absence of feed. The microalgae can make the gonad of the Chinese philosophy flea mature.
However, in the indoor daphnia cultivation process, due to the use of microalgae such as diatom and the like and the lack of an effective collecting device, residues are continuously accumulated in water, meanwhile, substances such as corpses and metabolites of daphnia are continuously released, so that the water quality is seriously deteriorated, and the living body of daphnia and other substances cannot be effectively and quickly separated.
