可用来行船的水域不同于一般小型河道。因为,能有船只通行尤其大吨位船只航行的自然水域,往往流速较大且水体较深。那么在这种水环境下好垂钓吗?在噪声较大情况下能有好的鱼获吗?质疑和否定声不绝于耳。然而,“实践是检验结论正确与否的惟一标准”。 The water available to sail on a boat is different from a typical small river. Because of the nature of ships that can have access to ships, especially large tonnage ships, they tend to have large velocities and deep water bodies. Is it good to fish in such a water environment? Can there be a good fish in a noisy environment? Question and denial are endless. However, “practice is the only criterion for testing the validity of conclusions.”
