Overall it's saying, if I may deduce as much, that overfishing by fisheries is endangering wildlife and that taxes are invested to slow this process. It's not arguing that commercial revenue should be deducted from the fisheries as if they were working for the government (and I'm not sure if the 1$ figure is ammortized by taxes payed from this industry or if the taxes are already included in it). One consequence would be to eat less fish and go get one if you really want it. Of course this would again create a market and it's a slippery sloap with regards to small scale commercial fishers. So, in a sense that's a gross calculation, if that's what you mean.
