Because the lake surface is wide, there are many aquatic organisms in the lake, and these aquatic organisms are the "food" for the lake fish. However, fathead, silver carp, etc., thrive when the water body is wide, oxygen is sufficient, and food is abundant. The fry of that year can grow to 0.5 to 1 kilogram. It can reach 2 to 3 kilograms in the second year, 3 to 5 kilograms in the third year, and the largest can reach 10 kilograms. When fishing, large-eye nets are strictly used. That is to say: this kind of net can only catch fish above 2 kilograms, while the small fish still stay in the water and continue to grow. This is a virtuous cycle, and Chagan Lake strictly controls fishing, so there is a large amount of fish for traditional winter fishing. No one can tell how many fish there are in Chagan Lake? There are big fish in the lake, ranging from more than ten kilograms to twenty or thirty kilograms. The king fish caught in 2016 weighed more than 50 kilograms and was auctioned for 858,000 yuan. Therefore, it is not objective to say that the fish caught in the winter in Chagan Lake are "bath fish". It’s okay to doubt that tens or even millions of catties are caught at one time, but this is not the case.
