Embodiment 1

[0022] Harvesting of artificially cultured Cladocera was carried out in a large-scale standardized pig breeding enterprise in Chongming, Shanghai. By applying the device and method for automatic harvesting of zooplankton of the present invention next to the tank for cultivating cladocera, the automatic harvesting of artificially cultivated cladocera is carried out.

[0023] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an automatic harvesting device in a 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 cladocera in the cultivation pool enter the upper box of the automatic zooplankton harvesting device continuously through a siphon, and the cladocera pass through the 150-mesh trap on the overflow slope under the action of overflow. Stainless steel screen 4, so that cladocera are intercepted and enriched in the zo...

Embodiment 2

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

[0036] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an automatic harvesting device in a 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 cultivation pond continuously enter the upper box of the automatic zooplankton harvesting device through a siphon, and the cladocera pass through the 200-mesh stainless steel plate on the overflow slope under the action of overflow. Screen 4, so that rotifers are intercepted and enriched in the zooplankton temporary storage box on one side of the stainles...

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 are small animals that float or swim poorly in a body of water. There are many types of zooplankton, from low-level tiny protozoans, coelenterates, ctenophores, rotifers, crustaceans, gastropods, etc., to high-level urochordates, almost every type has permanent representatives Among them, copepods with various types, large numbers and wide distribution are the most prominent. The distribution of zooplankton in the water layer is also wide, whether it is in fresh water or in the shallow and deep layers of sea water, there are typical representatives. Zooplankton is the natural bait for the larval stage of aquatic animals, and some aquatic animals even use zooplankton as bait for their entire lives. Therefore, the artificial cultivation of zooplankton is no...
