To catch herring, we must first understand the living habits of whales, catch herring by reservoirs and lakes, and be prepared to catch big fish. Whales slowly float when they eat hooks. Choose the right time to lift the pole to prevent the fish from running away. After the whale bites the hook, the float will float slowly and then sink. At this time, the pole should be lifted in time to prevent the fish from running away. You should also learn to walk the fish. You must pay more attention and work hard in this process.
