Embodiment 1

[0016] Embodiment 1 A kind of realization form of the culture method of a kind of red nematode of the present invention, it comprises the following steps:

[0017] 1) Prepare the culture tank: the bottom of the culture tank is smooth, the tank walls on both sides are 30 cm high, the width of the culture tank is 60 cm, and the length is 20 meters. A baffle plate is arranged at the first section and the end of the culture tank, and the culture tank The tank walls on both sides jointly form a rectangular breeding tank, and a water storage tank is arranged at the bottom of the breeding tank, which is used to store water when replacing vermicompost, so as to realize the recycling of breeding water;

[0018] 2) Prepare the matrix: add chlorella nutrient solution to the culture tank, inoculate the chlorella, and obtain the algae liquid. The algae liquid flows from the head end of the culture tank to the end of the culture tank and then enters the storage tank, and then pumps the water...

Embodiment 2

[0022] Embodiment 2 A kind of realization form of the culture method of a kind of red nematode of the present invention, it comprises the following steps:

[0023] 1) Prepare the culture tank: the bottom of the culture tank is flat, the tank walls on both sides are 40 centimeters high, the width of the culture tank is 100 centimeters, and the length is 30 meters. The first section and the end of the culture tank are provided with 10 centimeters of high baffles. Together with the tank walls on both sides of the culture tank, a rectangular culture tank is formed, wherein the culture tank has 6 layers, and the height between the two layers of culture tanks is 80 centimeters, so that each layer of culture tank has better light to meet For the rapid growth of chlorella, the end of the culture tank is provided with a drainage pipe connected to the head of the next layer of culture tank, and the multi-layer culture tank is connected end to end, forming a water circulation system with ...

Abstract

The invention relates to a red nematode cultivation method. The method comprises the following steps of 1, preparing a cultivation groove; 2, preparing a substrate, wherein chlorella is inoculated in the cultivation groove, an algae solution is obtained, the algae solution flows to the tail end of the cultivation groove through the head end of the cultivation groove and then enters a water storage pond, and the algae solution in the water storage pond is pumped into the head end of the cultivation groove through the effect of a water pump; 3, performing feeding and management, red nematode seedlings are uniformly added to the surface of wormcast, the water pump is started to work after red nematode enters the wormcast, in the cultivation process, water flow is kept constant, the dissolved oxygen, pH, ammonia nitrogen and chlorella concentration OD680 of water are monitored, and wormcast is added supplementarily after cultivation is performed for 5-10 days; 4, performing harvesting and continuous cultivating, wherein the water pump is stopped, a filer net is used for collecting red nematode, the wormcast is removed and added again, and next red nematode feeding and management are performed. By adopting the red nematode and chlorella symbiotic aquaculture mode, the method has the advantages that operation is easy, the red nematode quality is stable, the cultivation cost is low, and water resources can be recycled.

Description

technical field [0001] The invention relates to a method for cultivating red nematodes, in particular to a method for co-cultivating chlorella and red nematodes. Background technique [0002] Red nematodes belong to aquatic oligochaetes in annelids, and their body color is bright red or flesh red, orange yellow. Most of them live in the sewer sludge that discharges sewage or waste water, and are densely packed on the surface of the sludge. One end is fixed in the sludge, and the other end protrudes from the sludge to vibrate in the water. When it is disturbed, it immediately retracts into the sludge. The nutritional value of water worms is extremely high, and the crude protein content of dry products is as high as 62%. They are often used as bait for fish fry. There are a large number of parasites and pathogenic microorganisms in red nematodes caught in the wild, which have a great negative impact on the health of fish. Contents of the invention [0003] The technical pr...
