Can I catch crucian carp with sweet potatoes in the reservoir in winter?

It is not effective to catch crucian carp with sweet potato in reservoir in winter.

Live bait should be used in winter fishing, and there is a fishing proverb that "only red worms are used in winter fishing". Red worm is a kind of bait, with thin skin and tender meat, good color and fragrance, and it is inevitable that fish will be greedy when they see it. Besides red worms, red earthworms and nematodes can also be used.

Fishing in winter should take the initiative to find fish and use the method of "dragging the bottom". Fishing in summer is to "catch a hook" and fishing in winter should be to "catch a fish". In summer, fish are more active and have a big appetite. They can find food everywhere and make a nest, but not in winter. Because the water temperature is low, the fish basically stop foraging, and sometimes they just "barely" bite the food sent to their mouths, so fishing in winter is of little use as a nest. The specific method of "bottom fishing" is: throw the hook to the farthest place and stop for a minute or two. If there is no movement, you can "tease the fish"-put down the hook and move up and down two or three times. If there is no fish, drag the hook back about 30 cm and "tease the fish" again. So constant dragging and teasing can greatly improve the fish.
