wee fish

While fishing last year in Ardglass I noticed that there where some folk who kept every fish that they caught regardless of its size, I assume there is no actual restriction on how big or how small a fish should be before it can be kept, but I feel that small young fish should be returned. Has any other member noticed this "keep everything"happening??

Most of them lads are out fishing for a meal and not for fun, it happens all over the place don't mean to upset any one but I find more times than not they are not irish lads
