The raising of clothing fish

Ctenopharyngodon idellus is a photophobic insect, and most of the growth and development in its life is carried out at night. The place of living and the source of food are closely related to the human living environment. Brick and wood structure, lime-soil floor, moist old-fashioned houses and warehouses are its suitable places to live. Therefore, the collection of insects to choose the above places, but also to make use of its flat body, like to hide in the cracks, as well as the characteristics of gluttonous waste clothes, paper and greasy food, to make harvesting tools.

A. preparation and use of the trap: select the rough paper made of bamboo wool, plant straw and cotton yarn, which has not been printed with ink or chemical ink, and cut the paper which is 10 cm wide and 4 cm wide. Stir flour, water and a little sugar into a thick paste and heat it to make a paste. Use a round stick with a diameter of 1 cm as the axis and roll it into a paper tube with a bottom. Wash and dry the glass can, put the bottom end of the paper roll down, each bottle into 10 to 15, squeeze as tight as possible, so that the glass bottle does not fall out. Mix a little cake crumbs with a few drops of sesame oil and sprinkle evenly into each paper tube for use. Put the trap on the side under the pile of sundries that are not often turned over in the idle house. But the temperature is too high, smoke oil and gas is too large in the kitchen should not be placed. After 3-5 days, take the glass bottle lightly during the day for inspection, if you find that there is a clothing fish sneaking into the paper tube, you can gently put it into the feeder together with the paper tube. In order to attract the species as soon as possible, several more trapping tanks should be made, put into different environments, and harvested alternately. The general experience is that the trapping effect is better in spring and autumn.

B. according to the characteristics of the fish, the feeding equipment is designed: the fish has a strong crawling ability, which not only has a quick speed, but also can pass through a small gap, and can use the sharp tarsal claws on the feet, abdominal thorns and dense scaly hairs as attachments, and use a pair of multi-segmented whiskers at the end of the abdomen and a long tail between the whiskers as a booster to crawl quickly on smooth walls, even the body will not fall down on the glass. Therefore, these habits should be taken into account when designing breeding equipment.

C. Production and use of feeding utensils: a glass jar with a diameter of 20 cm and a height of 40 cm or a glass tank of the same volume should be used. Cardboard used as a support should be placed in the jar, and rough scraps of paper and cotton cloth should be put in as shelter and food. The upper mouth is made of 80 holes of copper yarn to make a very tight cover, and then a piece of glass slightly smaller than the cylinder mouth is pressed on the gauze cover to increase the weight of the lid and prevent the fish from escaping. The glass can also be moved left and right in a small range to adjust the humidity in the cylinder. Because the fish has no habit of mutilation, small size and no obvious metamorphosis, it can breed 150 million and 200 heads in the same feeding tank. Put the feeding tank in the dark, first put a little single feed, after 3-5 days, observe whether there is feces excreted after feeding at the bottom of the tank, in order to grasp the degree of food selection and food intake in the artificially controlled environment.
