Re: Educating fish
This is such an interesting topic.
I was talking to my brother about this the other day, we were talking about snapper sometimes being hard to catch in areas that have previously been very productive. People say that the snapper are being over fished or there aren't as many snapper left..
My thoughts are that the fish learn to avoid these areas after a bit of fishing pressure and it's not that there are "less snapper" but the snapper have just moved to different, less pressured areas.
I watched something ages ago about marine sanctuaries in NZ, just outside these areas there weren't many fish but inside the areas the fish were plentiful. It's like the fish understand that the area was less pressured which makes sense because all animals tend to stay clear of predators or areas were there are more people.
Also I've read that animals like whales and dolphins change migration patterns to avoid humans that hunt them.. I know mammals are much smarter but i think that instinct to avoid predators is present in all living things.
Cheers, Anth

Re: Educating fish
In principle I would agree with your snapper theory in PBB , and even more so around the popular piers et al...however, the sanctuary vs non sanctuary observation is biased in my opinion. Sanctuaries usually have been created to perserve a productive, functioning, and unique habitat so in my mind of course that location will natrually attract and sustain a higher population and variety of acquatic species. The animals goes where there is plentiful food, which just happens to be off limits to fisher folk. .... I'm no scientist so I could be talking complete bull.Sinsemilla wrote: ↑Fri Jul 05, 2019 12:26 pm

Re: Educating fish
Interesting read thanks for sharing. How often do you hear of a lost whiting spooking the school and the bite shutting down? Same with EP's but this is a short term reaction being shy of a lure and retaining that info is fascinating .
Check out Al's podcast for his insight into NSW marine parks Anth.
Anth not sure how vast an area your talking for Snapper? Have been told that Snapper being a scavenger will deplete certain sections of reef completely of food and shellfish etc in a season then move onto the next section of reef a season later.Sinsemilla wrote: ↑Fri Jul 05, 2019 12:26 pmThis is such an interesting topic.

Re: Educating fish
It could be and probably is the fish cleaning the area out and moving on but in some cases I've found fish, had guys anchor on top of me, the fish shut down, then i move around and within a few hundred meters find them again.. similar with whiting. Maybe after getting a lot of pressure in an area they might just move on completely? who knows..rb85 wrote: ↑Fri Jul 05, 2019 8:26 pmInteresting read thanks for sharing.

Re: Educating fish
interesting read. microevolution rather than just fishing pressure the way I read it.
