Embodiment 1

[0022] The harvest of artificially cultivated cladocerans was carried out in a large standardized pig breeding company in Chongming, Shanghai. The automatic harvesting of artificially cultivated cladocerans is carried out by applying the automatic zooplankton harvesting device and method of the present invention next to the clover cultivating tank.

[0023] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of the automatic harvesting device in the method for automatically harvesting and cultivating zooplankton of the present invention. A method for automatically harvesting and cultivating zooplankton. The main method is to continuously enter the upper box of the zooplankton automatic harvesting device through the siphon in the culture pond. Under the action of overflow, the cladocerans pass through 150 meshes on the overflow slope. Stainless steel screen 4, so as to intercept and concentrate cladocerans in the zooplankton temporary storage box on th...

Embodiment 2

[0035] The harvest of artificially cultivated rotifers was carried out in a prawn seed breeding farm in Shanghai. The automatic harvesting of artificially cultivated rotifers is carried out by applying the automatic harvesting device and method for zooplankton of the present invention next to the rotifer culture tank.

[0036] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of the automatic harvesting device in the method for automatically harvesting and cultivating zooplankton of the present invention. A method for automatically harvesting and cultivating zooplankton. The main method is that the rotifers in the culture pond continuously enter the upper box of the zooplankton automatic harvesting device through a siphon, and the cladocerans pass through 200 mesh stainless steel on the overflow slope under the action of overflow Screen 4 to trap and concentrate the rotifers in the zooplankton temporary storage box on the side of the stainless steel...

Abstract

The invention relates to a method for automatically collecting and culturing zooplankton, i.e., the zooplankton in a culture pool continuously enters an upper layer box body of a zooplankton automatic collecting device through a syphon pipe; under the overflow effect, the zooplankton is intercepted by a stainless steel sieve screen arranged on an overflow inclined surface under the overflow effect and is enriched in a zooplankton temporarily storage box arranged at one side of the stainless steel sieve screen of the automatic collecting device; a water body enters a lower layer water return box arranged at the other side of the stainless steel sieve screen of the automatic collecting device through meshes of the stainless steel sieve screen arranged on the overflow inclined surface, and is then pumped back into the zooplankton culture pool through a water return water outlet of the lower layer box body or is discharged. The method for automatically collecting and culturing zooplankton provided by the invention can be applicable to the zooplankton such as rotifers, cladoceran, copepods and artemia, and has the advantages that the automatic and continuous collection is realized; the labor is saved; the energy is saved; convenience is realized; the injury to the zooplankton is small.

Description

Technical field [0001] The invention relates to the technical field of zooplankton harvesting, in particular to a method for automatically harvesting and cultivating zooplankton. Background technique [0002] Zooplankton refers to small animals that float or swim in a body of water. There are many species of zooplankton, from low-level tiny protozoa, coelenterate, comb jelly, rotifers, crustaceans, gastropods, etc., to higher caudate animals, almost every type has a permanent representative Among them, the copepods are the most prominent with a wide variety, large number and wide distribution. Zooplankton is also widely distributed in the water layer, whether it is in fresh water, or in the shallow and deep layers of seawater, there are typical representatives. Zooplankton is a natural bait for the larval stage of aquatic animals, and some aquatic animals even use zooplankton as bait for life. Therefore, artificial culture of zooplankton is not only an important technology to ...
