A kind of rotifer continuous culture system and rotifer continuous culture method

Abstract

The invention relates to a rotifer continuous culturing system comprising a water source storage and treatment tank, a set of rotifer culturing tanks, a rotifer collection and culture solution precipitation device, and a culture solution recovery and storage tank. The invention also provides a rotifer continuous culturing method adopting the system. The method comprises the steps of culture device pretreatment, water source pretreatment, rotifer culturing, rotifer collection, and culture solution recovering. The above steps are repeated. The system and the method provided by the invention adopt a semi-automatic circulation technology. The operation is simple, and the system and the method are energy-saving and highly efficient. With a thermostatic-control culture technology, rotifer four-season continuous culturing can be realized. With a high-efficiency beneficial-composite-bacteria-fermented fertilizer culturing technology, through high-efficiency culturing of composite-bacteria-fermented organic matter and through water quality stable control with the composite bacteria, a rotifer culture nutrient source can be provided, the water quality can be ecologically controlled with flora, and culture solution precipitation, recovery and recycling can be realized. Therefore, the resource utilization rate is improved, pollutants caused by foreign matters can be reduced, and rotifer pure culture is ensured. The cultured rotifer has high-standard nutritional quality.

Description

technical field [0001] The invention relates to the technical field of biological cultivation, in particular to a rotifer continuous cultivation system and a rotifer continuous cultivation method for continuous cultivation of rotifers. Background technique [0002] Rotifer is a tiny multicellular animal, not only rich in protein, fat and carbohydrates, the three basic nutrients, but also contains various amino acids, vitamins, high unsaturated fatty acids and other biologically active substances. In the field of aquatic breeding, rotifers are often used as live carrier bait to transfer their own nutrients to seedlings, and their opening feeding effect is obviously better than other baits. At the same time, it has the advantages of strong vitality, rapid reproduction, suitable size, and is not easy to pollute water quality. It is the best natural basic biological opening bait for fish, crustaceans and other animals, and is widely used in aquatic nursery. [0003] In recent y...

AI Technical Summary

Problems solved by technology

One-time culture: high-quality rotifers, but frequent out-of-pond, labor-intensive; semi-continuous culture: easy accumulation of bait and feces in the pool, easy to deteriorate water quality, all need to be harvested regularly; continuous culture: a newly developed rotifer culture method, The device is an indoor closed system
