When you think about it it is really amazing the fact that there are wild fish in some of the rivers we fish. Lopat is right about the fall stock but there are people trampling all over the KLG all the time and there are still wild trout in there, as a matter of fact wild browns, brookies and rainbows. There are other rivers in this state that I think only support wild fish because of a lack of pressure and if they had people trampling through them all fall it would have a serious impact on the fish population.
In the case of the Farmington where there are very few wild fish (for the size of the river) maybe it would benefit from a closed season from say Oct. 15 to Jan. 1. Maybe it wouldn't help but I can tell that is a river that could produce a huge wild fish. You also have to look at it as does it really make a differnce on the Farmington? That river produce quality hold over fish year after year where as in NJ we don't have that. Any of our larger fish or going to be wild (few a far between) or a breeder that if its lucky lasts into the following spring.
In the case of the Salmon River it doesn't seem to be having a negative impact on the fishery but of course things could always be better. So my answer is I personally wouldn't fish to a trout on a redd but if the state leaves the rivers open its hard to get mad at people when they are with in the law. Also keep in mind NY closes most of the rivers where there are good populations of wild trout and in NJ sometimes no regulations are the best thing for our rivers. Keeps the people from going on the fish and game website finding out about a river and then going there and breaking the rules anyway.
