Micro-ecological preparations for the cultivation of plankton as bait for ecological breeding in small and medium-sized reservoirs

Abstract

The invention belongs to the field of aquaculture and discloses a micro-ecological preparation for medium-sized and small-sized reservoir ecological aquaculture feed plankton cultivation. The micro-ecological preparation for medium-sized and small-sized reservoir ecological aquaculture feed plankton cultivation comprises an active yeast preparation; mixture of the active yeast preparation and a nitrobacteria preparation according to weight part ratio of 1:1; mixture of bifidobacterium preparation and a bacillus subtilis preparation according to weight part ratio of 1:1; mixture of the bifidobacterium preparation and the nitrobacteria preparation according to weight part ratio of 1:1; or mixture of the active yeast preparation, the bifidobacterium preparation and the nitrobacteria preparation according to weight part ratio of 1:1:1; mixture of the bifidobacterium preparation, the bacillus subtilis preparation and the nitrobacteria preparation according to weight part ratio of 1:1:1. After the micro-ecological preparation disclosed by the invention is prepared into re-fermented fertilizers which are put into a water body, not only can the water of a reservoir be prevented from being polluted, but also the aquaculture yield of silver carp and bighead carp can be improved by means of feed increase, and fish products can also be guaranteed to have higher quality.

Description

technical field [0001] The invention belongs to the field of aquatic product cultivation, and relates to a microecological preparation for cultivation. Background technique: [0002] In my country, fish farming in small and medium-sized reservoirs is mainly based on the polyculture mode. There are two types of operation methods: "intensive culture" and "extensive culture", which are divided into bait feeding and natural stocking. Polyculture in small and medium-sized reservoirs is generally dominated by filter-feeding silver carp and bighead carp. In the intensive culture mode, fertilization and water are generally carried out according to different conditions such as climate change and water body nutritional status, and the time and amount of fertilization are determined with reference to changes in water body transparency (60-80 cm for medium-sized reservoirs) to ensure that the water color of the reservoir is green or light green. Fertilization generally uses organic or ...
