CATDOLL : CATDOLL: How to raise red nematodes artificially

In the natural environment, red nematodes mainly feed on bacteria, yeast, algae and organic debris (fragments of plants and animals). To artificially culture red nematodes, you must prepare the culture solution in advance. Take 4.5 kg of fertile soil (soil from the garden or vegetable garden) and 1 kg of straw (cut into 2 cm), pour them into a large tank, add 50 kg of water, stir thoroughly, place at 15-18℃ for 3-4 days, then filter with gauze. The filtrate is called the stock solution. Take a certain amount of the stock solution and pour it into another tank, then add 2-4 times the pond water, so that the culture solution is prepared. At this time, you can put a small amount of red nematodes into the culture solution, and keep the water temperature at 18-25℃. The red nematodes grow very fast and will multiply in large quantities to feed goldfish or other fish. In the process of cultivating red nematodes, add the stock solution at any time to ensure sufficient feed for the fish and worms.

Water earthworm: Also known as red nematode, red nematode, belongs to the aquatic oligochaete among the annelids, with bright red or blue-gray body color. They mostly live in the mud on the banks or riverbeds of rivers, densely packed on the surface of the mud, with one end fixed in the mud, and the other end trembling in the water with mud. Once disturbed, they immediately retract into the mud. Water earthworms have extremely high nutritional value and must be repeatedly rinsed in clean water before feeding. They are a favorite bait for goldfish and koi, and are also the main bait for eel fry. After the Huangpu River in Shanghai recedes, a large number of water earthworms grow in the mud on the banks, and people catch them in large numbers every spring and autumn.
