Prime time for mixed culture of aconite

Most of the farmers in Chaoshan, Shenzhen, Dongguan and other places in our province can get better economic benefits if they mix the four big domestic fish and tilapia with aconite in freshwater fish ponds. Mixed culture of aconite in domestic fish ponds has less investment and high profit, so it is worth trying to raise four major domestic fish and tilapia.

Aconite fish (scientific name grey mullet), mainly produced in the southeast coast of China, has a wide adaptability. It can not only live in sea water, but also be cultured in a completely fresh water environment. After artificial fishing and desalination, its fry are put into freshwater ponds and mixed with freshwater fish, which does not affect the production of domestic fish culture in the original fish ponds, nor does it need special culture environment and technology. Just manage it as before.

Aconite fish mainly eat plant food, algae mud and plankton and other fish leftover bait in fish ponds, as well as low-level nutritional foods such as rice bran, rice straw bran, wheat bran and corn meal. At the same time, aconite fish can improve pond water quality and play the role of "scavenger". Therefore, aconite mixed culture with other fish in freshwater fish ponds has the advantages of easy management, low cost and high income.

Aconite fish has rich meat and rich nutrition, and the finished fish is sold very well. it is a delicacy in restaurants, restaurants and ordinary people in urban and rural areas. "bright mullet" is a famous dish in the restaurant, which has won the reputation of the majority of consumers.

Aconitine mixed culture, 200 fish fry with a specification of about 3 cm per mu in fish ponds (water depth of 12 to 2 meters). If the fish ponds are usually fed with feed, aerator and good drainage and irrigation facilities, the stocking quantity can be increased appropriately. By diluting domesticated fish fry, the survival rate can reach 80% to 95%, the weight of fish in one year can reach 500 million 750 grams, the yield per mu is more than 150 kilograms, the market price per kilogram is 16 million 20 yuan, and the output value per mu can reach 2500 to 4000 yuan, the economic benefit is very considerable. Therefore, aconite is an indispensable high-quality species in aquaculture.

The stocking season of aconite is extremely strong, which is mainly completed before "Greater Cold" to "the Spring Equinox" every year. Once this prime time is missed, fish fry can not be found in fish ponds and the economic benefits of one-year culture will be affected. For this reason, mariculturists must make a good fry plan and order fish fry in advance to ensure that fish ponds improve the economic benefits of culture in existing fish ponds through mixed culture of aconite fish.
