Why is some worm blood also red?

The blood of insects does not contain oxygen and is not red because there are no red blood cells that make the blood red. However, with the exception of a few insects of the order Diptera (insects with only one pair of wings, such as flies, mosquitoes) and the larvae of the midge, which are red because they contain heme, the blood of most insects is colorless, yellow, green, blue, or light amber.

depends on its hemochrome.

Bloodworms and bloodworms are:

1. Bloodworm: Bloodworm is also called Daphnia, which is a small crustacean that belongs to the phylum Arthropods, Crustacea, and Clamocera. Called fish insects. Daphnia is small, about 2 mm long, light flesh red, and lives in fresh water.

The body is divided into a head and a torso, with dorsal armor, and the torso has 5 pairs of trunk limbs, which are motor and respiratory organs. Not only is it high in protein, but it also contains amino acids, vitamins and calcium, which are essential for fish.

Daphnia is an excellent bait for freshwater-fed fish such as yellow eels. The cultivation is relatively simple, and a small amount of breeding can be used in bottles, cans, tanks, etc.; A large number of breeding can be used in earthen ponds and cement ponds.

2. Blood worms: Blood worms mainly refer to the common name of several aquatic annelids with bright red body colors. Including oligochaetes, tremblingworms, and tremblingworms, which can be used to raise tropical fish.

Polychaetes, S. sapiaceae, and species of S. s. spp., sometimes called blood worms, are found on the east coast of North America and can be up to 37 cm long. The aquatic larvae of some insects of the family and the genus Mosquito are also known as bloodworms.

There are many kinds, it depends on what kind of food the worm eats, the blood of the grass-eating insect is mostly yellow and green, and the blood of the carnivorous insect is mostly red and white, as long as you are observant, the problem will always be solved.

The insect body is rich in nutrients and contains dry matter; In dry matter, the protein content is 41% to 62%, the fat is 2% to 8%, and the calories are 4 cal. The larvae of midges are of appropriate size and palatability; Comprehensive nutrition, can promote the growth and development of fish; It will not cause water pollution in the feeding pond; The larvae of the midges remaining in the rearing pond do not cause harm to the breeding objects, because they ingest a large amount of organic debris in the water body, and also have the effect of purifying the water quality. In particular, in the larval stage of many economic aquatic animals, the larvae of midges mosquitoes are used as their main natural bait.

Therefore, it is of great significance to cultivate a large number of midges larvae to raise larvae of economic aquatic animals.

There are about 5,000 known species of insects in the world, which are similar to common mosquitoes, but the main difference is that the antennae are densely covered with fine hairs, like feathers. Another difference is that its mouth (mouth needle) has degenerated and is no longer capable of sucking. Therefore, we can say that it does not bite.

Bloodworms also have a knack for living in a relatively oxygen-deprived environment. Because it has heme in its body, which is why it is blood-red.

Mosquito larvae have become an important biological resource. It has a wide distribution in all kinds of water bodies, and its biomass often accounts for 50% to 90% of the total benthic fauna in the water. Bloodworms are an important link in the food chain in the water body, and are excellent natural bait for a variety of economic aquatic animals such as a variety of fish, shrimp, crabs, turtles, turtles, etc.

The larvae are highly nutritious, with protein content accounting for 41% to 62% of dry matter and fat accounting for 2% to 8%.

Mosquito larvae, also known as blood bloodworms, are widely distributed in all kinds of water bodies, and their biomass often accounts for 50% to 90% of the total number of benthic animals in the waters, and is an excellent natural bait for a variety of economic aquatic animals such as carp, crucian carp, mrigal, sturgeon, herring, yellow eel, loach, river crab, turtle, turtle, etc.
