1 net fished out 400,000 Jin! Why does Chagan Lake harvest in winter every year? Where did the fish come from?

Every year from winter solstice to Spring Festival, it is the prime time for fishermen in Chagan Lake, Songyuan City, Jilin Province to catch large winter fish. Winter fishing in Chagan Lake is a local traditional fishery production mode. Nowadays, the local tourism industry has been combined and become a special way of tourism.

As the saying goes, "people are afraid of being famous and pigs are afraid of being strong." Because Chagan Lake is famous for its winter fishing, some people who don't understand it will take it for granted that Chagan Lake has a bumper harvest every year, which is impossible in the natural state, so they think that Chagan Lake is a "bathing fish". So what is the truth?

At the 18th Ice and Snow Fishing and Hunting Cultural Tourism Festival in Chagan Lake, China, it was shocking that the fishermen of Chagan Lake caught 400,000 Jin of fish in one net, but we should know that the catch of Chagan Lake is about 3 million Jin every winter.

Chagan Lake insists on not cultivating around the lake, not throwing any feed, and not cultivating in cages or purse seines. In this case, the natural proliferation of fish is slow, it is impossible to harvest every year, and the population may even drop sharply because people catch it every winter. How to ensure a bumper harvest every year in Chagan Lake?

In fact, as early as the last century, Chagan Lake was on the verge of exhaustion and the water quality deteriorated. In order to protect the local ecological environment and protect the interests of local fishermen, the local government began to inject water into Chagan Lake, and in 6,543.8+0,992, it coordinated a loan of more than 5 million yuan, and put in 6,543.8+0.3 thousand Jin of fry at one time.

The local fishing industry has also been rectified and the crazy predatory fishing has been stopped. Instead, it insists on orderly fishing and adopts the strategy of "grasping the big and releasing the small" to make the local fishery resources sustainable.

The local area also stipulated the mesh size of fishing nets. In the past, local villagers fished for everything, including flies' legs and meat, big fish and small fish. Later, the local government stipulated that the mesh for winter fishing should be changed from 1 inch to 6-inch mesh, so that the big fish can catch for more than 5 years and the small fish can continue to survive and reproduce in Chagan Lake. Therefore, when fishing in Chagan Lake in winter every year, you can obviously see that the fish caught are very big, and the size of more than 20 kilograms is also very common.

In addition, in order to protect the local fishery resources, Chagan Lake has to suspend fishing every year and release fry regularly. Every year, fry are released into the lake, and the ratio of "one grass and three silver carp" is adopted. Regular delivery guarantees a bumper harvest every year.

Many people will say that local fry are released regularly, but the released fry are a little big. But in fact, the size of fry released locally is standard, ranging from 5 inches to 8 inches. Not too big or too small. If it is too large, the mortality rate will be high, and a little scaly fish will die.

Putting fry regularly, ensuring the safety of local water quality, and adopting the strategy of "big fish eat small fish" in fishing all make the fish resources in Chagan Lake develop sustainably, and also provide a guarantee for the annual harvest.

Many people worry that the fish in Chagan Lake are too famous, and some people will release farmed fish to Chagan Lake and catch them ashore.

In fact, "bathing fish" is difficult to appear locally, and "bathing fish" and "bathing crab" may appear elsewhere. Make use of the brand effect of local high-quality origin to increase the unit price of agricultural products.

However, it is difficult for Chagan Lake to do this. On the one hand, Chagan Lake does not adopt purse seine culture and cage culture, but is naturally stocked in Chagan Lake. No one can be sure where the fish will go after stocking, and it may not be caught at all, which will not increase the local fishery output.

On the other hand, when fishing in Chagan Lake in winter, the maximum fishing quota is set, and the annual fishing amount is about 3-3.2 million Jin. These yields are within the tolerance range for Chagan Lake, and there is no need to transport fish from other places and pretend to be local fish.

In addition, Chagan Lake mainly produces chubby fish, but the life of adult chubby fish is fragile, and the mortality rate is high during transportation, unlike the survival rate of crabs. If the cultured fish are transported to Chagan Lake, a large number of people will die on the way, which is not cost-effective.

Moreover, the important task of winter fishing in Chagan Lake is not to fish, but to use local fishery resources to develop characteristic tourism and promote local economic growth. Winter fishing in Chagan Lake has become a local business card. In order to make winter fishing sustainable, the local government has taken various other measures, and there is no need to put in "bathing fish".

The premise of annual harvest in Chagan Lake is: putting fry every year, strict water quality management, the size of fishing nets, and the sustainable fishery resources management plan implemented to protect Chagan Lake, which makes winter fishing in Chagan Lake a world-famous business card.
