I feel a bit weird when I read this kind of topics.
Fo me fishing is and as always be about looking after healthy fish (if possible wild) and finding a way to make them bitting. I do not consider long linning as fishing, but if it is not illegal, I do not feel like I have the right to tell people not to do that. I would also prefer having an annual limit for the catch and even If I like bringing fish at home from time to time, I would be happy to fish more rivers completely catch and release. But eh, who am I to say that it is what fishing really is about?
In France, in lot of rivers, every year when trout fishing open, tons of farm fish are released. This poor fish are used to be fed by humans... so I let you imagine what happens, the worst fisherman you are, the more fish you catch... I do not consider that as fishing, but it is legal...
So do we have the right to say what fishing really is? I guess yes, but in this case this must go with some regulations. We cannot just say, the way I fish is better than yours just because I think it is.
This is just my opinion
sorry for the poor English
