According to the normal time node, after April every year should be the day when the grass carp comes out of the pond the following year, and the price is not bad, but 2023 is unusual, not only the price of small grass carp is very low, but also cannot be sold. Even many fish have diseases such as rotten bodies, and the whole army will be wiped out if they are not careful. How is the mood of the farmers at this moment? Although the market is particularly bad, there are still a group of aquaculture owners who can make some money when everyone else is losing money because of the low bait coefficient of fish and low feed costs.
The main reasons for the difficulties of grass carp farming last year are as follows:
(1) At the beginning of 2022, affected by the epidemic and price, the small grass carp dried the pond late, resulting in a late feeding time and insufficient growth time, and most of the small grass carp could not reach the market specifications at the end of the year, so there was no price;
(2) Due to the influence of early rot disease, some pond seedlings died and were forced to dry ponds to re-seedling, resulting in high cost of seedlings and affected growth;
(3) The rise of raw materials has caused the rise in feed prices, due to the thin profits of grass carp, farmers have a contradictory concept, can only choose cheap feed, fish not only grow slowly but also frequent diseases, and the cost of treating drugs is very high;
(4) There is a misunderstanding in the farming concept of farmers, thinking that fish can be raised well as long as the bottom is changed and detoxified, resulting in farmers ignoring the problem of bait coefficient;
(5) The cost of feed is too high and there is almost no profit.
The author visited the breeding bosses who used Yumeikang feed and Yukang Tai 9+1 model throughout the whole process in 2022, and the output of the entire breeding cycle was 200 jin more than that of Tangkou using other brands of feed. If the minimum 10% fat loss rate in winter is considered, one ton of feed fish is 1200 jin, and the feed cost of fish is reduced to 3.7 yuan / jin, which has a good role in reducing breeding costs and increasing aquaculture benefits.
At the same time, because Yu Kangtai can effectively enhance the physique of grass carp, it has a good protection and repair effect on the liver, and can enhance the disease resistance of grass carp, thereby reducing the occurrence of dead fish. The use of Yukangtai reduces the use of animal protection products, thereby reducing the input of breeding costs. Looking at the accounts of the breeding bosses who use Yu Kangtai, comparing the animal protection investment in the past three years, it is found that after using the Yu Kangtai 9+1 model, their animal protection investment has been reduced from 1200 yuan / mu to 800 yuan / mu. Moreover, the mortality rate of fish is reduced to 10%, on the one hand, the cost is reduced, and the profit margin is increased. On the other hand, it reduces the death loss and directly increases the benefits of farmers.
A large number of data show that Yu Kangtai has a very good effect in reducing the bait coefficient and reducing the mortality rate of grass carp, and when the market is not good, only by reducing the bait coefficient can the cost reduction and efficiency of grass carp be achieved.
