I fear it could be serious, this time. In Belgium, Netherlands and Germany too, voices are raised against "sport" fishing. The trend comes from the US where a battle is raging between pro's and sport fishers about who has right to the billfish or striped bass that's (still) out there.
The basic reason is that professional fishermen , who DO pay heavy licences, are more and more limited in their rights to catch (and that's a eufemism). meanwhile sport fishermen are stepping into the gap, supplying local restaurants etc. with heaps of fresh fish, thereby influencing the market demand for the fishermen-caught fish. That's not fair, is it?
Problem is thus that there are too many fake amateurs on the water. Catch a cod for sport, OK, but 180Kgs?
