西北地区的主要河流一般都会有许多支流,支流又由许多溪流汇集而成,便形成了“有山必有沟,有沟必有溪,有溪必有鱼”的情况。每逢阳春三月冰河解冻后,鱼群就会从大河中逆水而上,经过支流,到溪流水草丰富的浅水中产卵,这便是春季溪钓的大好机会。北方的春天要比南方晚一两个月,所以阳历5月甚至6月同样是溪钓的好时机。 There are many tributaries of the major rivers in the northwest region. Tributaries are formed by many streams, forming a situation where there must be dams in the mountains, dikes in the ditch, and streams in the river. Whenever the spring ice glaze thawed in March, the fish swarmed from the river to the tributary to the rich streams of grass and spawning in the shallow water. This is a great opportunity for spring stream fishing. The northern spring is a month or two later than the south, so the Gregorian May or even June is a good time for river fishing.
