A 6-7 cm platypus fry is about 6.5 yuan, and the high survival rate can reach more than 70%, the low one is only 20%, and the average survival rate is about 50%. When the platypus grows to 0.5 kg and can be put on the market, it needs to consume about 6 yuan's feed, and it also needs about 3 yuan's contract fee, labor fee and electricity fee. Based on the survival rate of 50%, the cost per kilogram of duck-billed fish is about 44 yuan. The amount of money depends on how much you plan to raise and multiply it by the cost.

Duck-billed fish farming is a popular special farming project in recent years. In recent years, with the continuous expansion of market demand, duck-billed fish farming has gradually been recognized and accepted by people. Compared with the original breeding project, duck-billed fish breeding has higher technical requirements, and there are not many previous experiences for reference.

According to the current market price, the wholesale price per kilogram of duck-billed fish is around 70 yuan, and the retail price has slightly increased, about RMB 0/00 per kilogram/kloc, and the duck-billed fish after being made into finished dishes has risen to 220-440 yuan per kilogram. The average farmer can make a profit of about 26 yuan per kilogram. But the profit of raising one kilogram of common perch is only about 2 yuan when the market is good, and it can only last about one yuan in general. In contrast, the profit of raising duck-billed fish is more than ten times higher.

The breeding cost of platypus is relatively high. The breeding cost of one kilogram of platypus is probably 44 yuan, and the price of one kilogram of platypus in the market is about 100 yuan, so its profit margin is still relatively large. For friends who want to breed duckbill fish, it is best to make relevant preparations before breeding, learn more experiences and lessons, and also do relevant work in breeding, so as not to be sloppy.
