I like the overall look of both and the text style on both is good. However I'm not convinced that either pictoral element is really correct. Out of the two designs, I prefer entry 16 as i don't see that entry 15 really says or means anything and is probably a bit too busy with the G inside the logo.
On entry 16, I like the different layers of blue because that could indicate different types of water that people fish on. The thing I don't like is the overall shape becuase it seems a bit 'hard' and disjointed. Perhaps if it has that style but in a different shape?
Hope that helps and look forward to seeing other submissions from you
