Is it effective to use black earthworms to catch grass carp in winter?

Black earthworms are effective for fishing grass carp in winter. Earthworms are known as universal baits and can be used all year round, especially in the cold winter. Earthworms are found everywhere and can be found in the ground all year round.

Earthworms are small and slender. Tongqing earthworms are rich in protein, fat and amino acids. There are two types of earthworms. One is the red earthworms we use for fishing. The other is the black earthworms. Black earthworms also include green earthworms. They are slightly larger.

Black earthworm farming

The location of the earthworms is the most important issue for earthworm farming. Outdoor places are most suitable for earthworm farming, where earthworms have strong vitality and reproduce quickly. Indoor places are generally suitable for small-scale farming or the farming of newly hatched earthworms, because newly hatched earthworms are small in size and have a limited range of activities.

The breeding bed is set up outdoors and protective measures must be taken when there is too strong sunshine, hot wind and rain. It is best if there is natural shade from trees, otherwise artificial cover must be added.

Earthworm breeding species selection

There are several economic earthworms for you to choose from. There are many varieties of earthworms in the world, about 27,000 species. There are also more than 160 varieties of earthworms in my country. According to their living environment and preferred feed, they can be divided into: dung earthworms, straw earthworms, water earthworms, soil earthworms, and vegetable earthworms. We can choose varieties according to their uses and feed sources. The most developed in my country is the Eisenia fetida. The selected varieties of Eisenia fetida include: Daping No. 2, Beixing No. 2, Beijing striped earthworms, etc.

1. Eisenia fetida: commonly known as red earthworm, it belongs to the category of dung earthworm. This kind of earthworm likes to eat all kinds of livestock and poultry feces, and is suitable for all kinds of farms and households to eliminate the pollution or harm of livestock and poultry feces to the environment. The earthworms produced can be used as protein feed for all kinds of livestock and poultry, forming a virtuous cycle in the breeding industry, with considerable benefits.

The individual earthworms of Eisenia fetida are relatively small, generally 90-150 mm in length and 3-5 mm in diameter. When mature, they weigh an average of 0.5 g each. They are purple in color with a light yellow tail. The egg sac is small and oval in shape, with both ends extended and one end slightly short and pointed. Each egg sac contains 3-4 small earthworms, with as few as 2 and as many as 6. Although they are small, they have a large reproduction capacity and high yield, making them suitable for artificial breeding.

2. Beixing No. 2: It is a dung earthworm, which was introduced from Hokkaido, Japan by Tianjin Science and Technology Commission in 1979. Like Daping No. 2, it is a new variety of Eisenia felis improved and cultivated. It is 90-150 mm long, weighs about 0.5 grams, has a growth period of 70-90 days, eats all kinds of livestock and poultry feces, has strong feces dumping ability, high reproduction rate, high efficiency, and is suitable for artificial breeding.

3. Pheretima Williamii: commonly known as green earthworm, it belongs to earthworm and giant earthworm. Individuals are relatively large, generally 150-250 mm long. When sexually mature, each weighs an average of 5.2 grams, and the body color is green-yellow or blue-gray. The egg capsule is pear-shaped, and each egg capsule contains one small earthworm, and very few have two. This earthworm swallows a large amount of soil and is a soil earthworm. It is suitable for breeding in vegetable gardens and feed fields. It likes to swallow fertile soil and has strong wildness. Although each egg capsule contains only one small earthworm, the individual is large and suitable for artificial breeding.
