Donegal is a good spot for turbot, one of the few decent places to target them from the shore in Ireland
despite it being a very decent catch from the shore, it certainly isn't a big turbot in general. sorry to burst your bubble..
it hasn't even reached maturity yet (which occurs at approx 49cm) and so its still a juvenile fish. these fish can reach 100cm in length and weigh 30 and 40lb! this wee guy is maybe 1lb or just over it
i'd still be very happy with it from the shore, for sure. it is a very nice fish and very few people would get one like that in a lifetime from the shore
hope this answers your question....
so yeah, well done!
