Shrimp lycopene is a kind of carotenoid. When this pigment is combined with protein, it will turn yellow, orange, purple, green and blue due to different protein, so the arowana will change color after eating it, and become yellow, orange, purple, green and blue. Shrimp lycopene makes the fish's liver excrete the eaten shrimp lycopene on the scales, so our arowana will become more and more red, or change color to yellow, orange, purple, green, blue and other colorful rare colors. Changing or deepening the body color of arowana is the key to improve its quality and value.
Pet breeding is a rapidly developing emerging industry in the world economy, and it is a good way for people to relax and improve their quality of life. It has been highly valued by all countries. Arowana is a plaything consumed by nobles. Mainly produced in Asia and distributed in Indonesia, Malaysia, Singapore and Thailand in Southeast Asia. The main domesticated varieties are red, orange, white, black, gold, silver and cyan arowana. Because it keeps its original shape, fish are beautiful and ornamental, and are on the verge of extinction. It is famous for its living fossils and has archaeological and academic value. Young fish are only 10 cm to 12 cm long, and the price of each fish is above 1000 yuan. The price of an adult arowana is as high as several hundred thousand yuan. It is the most expensive ornamental fish species at present. In Singapore, Indonesia and Malaysia, you can buy more than 500 kinds of arowana mainly operated in the world, accounting for 85% of the ornamental fish species in the world. Sales account for most of the world ornamental fish market, which brings rich economic returns to the region. In these countries, the scale of arowana culture is huge, and the supply of live worms is in short supply. Only100000 live centipedes are imported from China every year, and each imported dracunculiasis is 15 cents. Calculated by 700 yuan per kg, the price is 1000 RMB/kg, and the market demand and potential are huge.
The feeding of wheat worms is basically the same as that of Tenebrio molitor or black powder insect, but special attention should be paid to the main links such as feed and temperature.
Wheat worm has a large body shape, the growth cycle and speed are the same as that of Tenebrio molitor, with diverse feeding habits, wide adaptability, wide feed sources and low feeding cost, which is suitable for residents all over the country, and its output is 3-4 times that of Tenebrio molitor, with remarkable economic and social benefits. The breeding of barley nymph started earlier in the world, and there is no successful report of large-scale breeding in China. Since the demonstration farm was introduced in 2005, through long-term experiments and breeding, it has fully mastered its ecological habits and growth and reproduction laws, solved key technologies such as delivery room setting, feed formula, temperature and humidity control, pupation and eclosion, and scientifically summed up a set of best breeding modes, which provided a powerful bait guarantee for the rapid development of special aquatic animals and rare livestock and poultry. As a source of high-grade bait in protein, dracunculiasis has a very broad market demand at home and abroad. Each foreign wheat worm 15 points, calculated as 700 per kilogram, the price is RMB 1000 yuan; In the domestic market, the price is often out of stock per kilogram 100 yuan, and the market potential and demand are broad. The feeding technology of wheat worms is basically the same as that of Tenebrio molitor, but it is slightly different in plant setting, feed formula, temperature and humidity control, pupation and other major links. Once the breeder is trained, he can master the essentials and operate independently. The main equipment of wheat worms is screen and feeding container. Mesh box: It is used for adults to lay eggs, and it is also a tool for separating eggs, insects and bait. The wooden box frame can be used to install gauze with 3 mm mesh. Containers: cabinets, boxes, pools, boxes, etc. The size of the cage depends on the number of insects, and the maximum size is 70 cm× 45 cm× 18 cm (we all keep it in this plastic frame). The inner wall of the container should be smooth, so as to prevent the barley worm from crawling out and prevent the harm of spiders, geckos, mantis and other insects.
The best place to raise wheat worms is in a room with sunny lee, warm winter and cool summer. Don't be too bright, and keep warm. The optimum temperature is 18 ~ 30℃ and the relative humidity is 70%. When the temperature is high in summer, sprinkle water on the ground to cool down; Heat preservation is needed in winter to ensure the normal growth and development of wheat insects. The processing methods of the above two feed formulas are as follows: mix all ingredients evenly, because the added fermented straw is wet, it can be directly mixed and fed, and wheat and insects like it, and the mixture should be fed immediately; You can also add a proper amount of water, knead it into dough, press it into small cakes, and dry it before use. Conditional farmers can use feed pellet machine to expand into granules. The practice of the above feed formula proves that the effect is very good, cannibalism rarely occurs, the growth condition is good, and no disease occurs. Please refer to the relevant information for the treatment methods of straw and chaff. The above feed is refined feed. In addition to fine feed, wheat worms need a lot of green feed, such as melon skin and vegetable leaves. In addition to these green feeds, we feed more ryegrass and Pennisetum, and it is best to simply break them before feeding them. The ratio of concentrated feed to green feed is about 1: 2. The cost of feeding 1 kg barley nymph larvae is calculated as follows: about 1.5 kg concentrate feed and about 3 kg green feed. With the maturity of aquaculture technology, the cost of aquaculture will be further reduced.
