How to breed red nematodes at home?

The sludge rich in organic matter was selected as culture material, submerged with water, soaked for 2-3 days and then added with rotten fertilizer and mixed feed. It can be introduced when the temperature drops to about 28 degrees, and it is appropriate to inoculate 500-750 grams per square meter of culture area. Generally, the breeding peak of red nematode can be entered after 30 days.

I. Life habits of red nematodes

Red nematodes like to live in the mud of micro-muddy waters rich in organic matter (commonly known as slow-flowing black sludge of smelly sewers), generally lurking 10-25 cm below the mud surface and hiding deep in the mud at low temperatures. Red nematodes like dark fear of light, can not be exposed to the sun, eating soil to absorb organic humus, bacteria, algae for a living. The red nematode was sexually matured at about 2 months, hermaphroditic, allogeneic fertilization, and the eggs were enclosed in a cystic cocoon composed of a transparent glial membrane. Generally, a cocoon contains 1-4 eggs, and most of them contain 7 eggs. 2-6 cocoons can be excreted from each adult during the reproductive period. When the water temperature is 22-32 ℃, the incubation period is generally 10-15 days, and the life span of artificial culture is about 3 months.

2. Nutritional value of red nematode

Red nematode has rapid reproduction and high nutritional value (62% of crude protein in dry matter, 35% of essential amino acids and 98% of nitrogen recovery). It is a favorite food for many aquatic animals in the seedling stage. it is also the main food for benthic fish such as Sturgeon, mandarin carp, crucian carp, Loach, baby fish and rice field eel.
