法国“四月鱼”

In addition,the linkage between April Foolery and the Springtime is seen in another story that traces the origin of the custom back to the abundance of fish to be found in French streams during early April when the young fish had just hatched. These young fish were easy to fool with a hook and lure. Therefore, the French called them 'Poisson d'Avril' or 'April Fish.' Soon it became customary to fool people on April 1, as a way of celebrating the abundance of foolish fish.

此外，四月愚行同春天的关系还可见另一个故事，那个故事提到4月初小鱼刚孵出，法国溪流里满是鱼，这些小鱼下个钩放点饵就很容易上当。因此，法国人就把这些小鱼称为四月鱼。很快，在4月1日愚弄别人就成了庆祝轻松大量捕获容易上钩的傻鱼的一个习俗。
