The method is an important technology in wood frog industrial high-efficiency breeding.

The invention provides a coating material, a hermetia illucens larva living thing coating bait, and a preparation method and application, and belongs to the techncial field of application of industrial aquaculture baits. The coating material comprises the following preparation raw materials of defatted soy flour, antheraea pernyi powder, soybean oil, corn starch, multivitamin and minerals tablets,calcium, phosphorus, magnesium, zinc and ferrum rapidly enriching tables for livestock and xanthan gum. The coating material is reasonable in matching of nutrient components, and the hermetia illucens larva living thing coating bait prepared from the coating material can meet requirements of Chinese forest frogs for growth, development, oil generation and propagation. The hermetia illucens larvaliving thing coating bait solves the problems that at current, the forest frog living insect bait is single in kinds, and unbalanced in nutrients, the cost of the baits is greatly reduced, and the content of nutrient components required by the forest frogs can be manually controlled and balanced, so that the oil quality of forest frogs which are artificial bred and the oil quality of wild forest frogs are not obvious in difference, the oil generating period is shortened by 30%, and the hermetia illucens larva living thing coating bait has important significance in realization of industrial large-scale cultivation techniques of the Chinese forest frogs.

The invention discloses a processing technology of instant Chinese forest frog. The raw materials of the instant Chinese forest frog comprise dry rana japonica oil, lotus seeds, red dates, Chinese wolfberry, honey and honeysuckle powder. The preparation method comprises the following steps that the dry rana japonica oil is subjected to impurity removal and crushed into powder, water is added, ozone is introduced at the same time, dipping and soaking are carried out at 6-10 DEG C for 10-15 h, and dehydration and fishy smell removal are carried out; the lotus seeds, the red dates and the Chinese wolfberry are added into boiled water, cooking thoroughly, taking out and mashing are achieved, dry rana japonica oil powder is added, and the honey and honeysuckle flower powder are added while stirring; and the formed mixture is put into a jacketed kettle, 200-300 parts of water is added, heating is achieved to fully mix and dissolve, filtering is achieved to remove impurities when the water is concentrated to 30-40 times of the instant Chinese forest frog raw material, cooling and bottling are achieved, and sealing and sterilizing are achieved at high temperature to obtain the product. According to the processing technology of the instant Chinese forest frog, the problem of single eating method of wood frogs is solved, the Chinese forest frog food which is delicious in taste and rich in nutrition is provided, and the Chinese forest frog food is similar to jelly in mouth feel, rich in nutrition, fresh, cool and slightly sweet in the mouth feel and has a certain health-care effect.

The invention relates to the technical field of wood frog culture and discloses a hibernation security protecting pond for outdoor wood frog culture. The hibernation security protecting pond comprisesa culture pond, wherein side boxes are fixedly mounted at the left side of the top of the culture pond and the right side of the bottom of the culture pond, lead screws are movably nested inside theside boxes, bottom ends of the lead screws are movably nested in internal walls of the side boxes, top ends of the lead screws penetrate through the side boxes and extend out of top ends of the side boxes, and rotary rods movably sleeve outer sides of the side boxes. According to the hibernation security protecting pond for outdoor wood frog culture, the lead screws can rotate by using running fitbetween the rotary rods and gears through turning turntables, sleeve chucks can rotate through the rotation of the lead screws, sleeve plates can rise or fall by using the fit between the lead screwsand the sleeve chucks to change the height of the culture pond, the sunshine irradiation to wood frogs can be increased by lowering the sleeve plates to meet the needs of the wood frogs on growth, the wood frogs can be prevented from escaping through rising the sleeve plates, and thus, the practicability of the security protecting pond is improved.

A kind of seedling management technology of wood frog, its feature comprises before the young frog enters the frog enclosure with 1ppm bleaching powder full fence disinfection, puts young frog in a suitable place to breed by the density of 300-400 per square meter of frog enclosure, sprays water once a day, It should not be too much to prevent the ground from accumulating water. Feed at 4-5 o'clock in the morning or 5-6 o'clock in the afternoon. Every day, each young frog feeds 1-2 2-3 instar Tenebrio molitors. After 40 days, feed twice a day and feed yellow powder 2-3 of 4-5 instar insects; placing corn stalks or branches and leaves around the frog circle is conducive to the landing of young frogs; it solves the problem of forest frog breeding in coastal areas, due to the low survival rate of seedlings in the climate environment, and is widely used in Used in coastal areas.

A kind of adult frog management technology of cultivating Rana, its feature comprises putting into a suitable place to grow frogs at a density of 40-50 per square meter of frog circle, feeding mainly the larvae of Tenebrio molitor, once a day at 4-7 o'clock or At 5-7 pm, feed 3-4 wood frogs each time. It solves the problem of slow growth in the cold zone and cannot meet the needs of the society, and is widely used in coastal areas.

A seedling management technique of wood frog is characterized by comprising steps of sterilizing the whole fence by 1 ppm chlorinated lime before froglets enter a frog house; stocking froglets according to the density of stocking 300-400 froglets in every square meter of the frog house; spraying water once every day and do not spray too much so as to prevent waterlog at the ground; feeding at every morning 4-5 a.m. or afternoon 5-6 p.m.; feeding 1-2 yellow mealworms at 2-3 years old for every froglet every day; feeding for two times every day after 40 days; feeding 2-3 yellow mealworm at 4-5 years old; placing corn stem, branch leaves and other at surrounding of the frog house for helping froglets to go ashore; the technique solves the problem of low survival rate due to the climate environment when the frogs are cultivated in the coastal areas, and is widely applicable to the coastal areas.

The invention provides a coating material, coating bait for live black soldier fly larvae, a preparation method and application thereof, and belongs to the technical field of industrialized breeding bait application. The coating material of the present invention includes the following raw materials for preparation: defatted soybean powder, tussah moth powder, soybean oil, corn starch, multi-dimensional element tablets, calcium, phosphorus, magnesium, zinc and iron for veterinary rapid supplementation and xanthan gum. The nutritional components of the coating material of the invention are reasonably configured, and the coating bait for living black soldier fly larvae prepared by the coating material of the invention can meet the needs of growth, development, oil production and reproduction of Rana chinensis. The black soldier fly larvae live coated bait of the present invention solves the problem of single species and unbalanced nutrition of the live insect bait of the forest frog, greatly reduces the cost of the bait, artificially controls and balances the required nutrient content of the forest frog, and makes artificial There is no significant difference in the oil quality of the cultivated wood frog and the wild wood frog oil, and the oil production cycle is shortened by 30%, which is of great significance to the realization of the industrial scale breeding technology of the Chinese wood frog.
