Wow what an important thread!!
From all point of vie you are right
Fish can learn & become most suspicious!
There was a time in Israel that most groupers used to hide from
Divers with tanks & the free divers were getting most of the fish
You were able to come very close to a grouper by free diving
But as soon he heard the bubbles he is gone. Now however it is difficult
To come close even in free diving they just learn in the time
sargo is an interesting one ,one of the most popular one in Israel
You can find them from the depth of 1 meter, the small ones (till 200 gr )
Are coming close but as big they are the will keep a good distance from you
Sometimes it is taking time to come close i have 2 ways to have a good
Shutting target:
1. Looking down to see where are some big examples
Getting to the bottom quietly with left hand helping to come close
To the range, hiding against a rock aiming & waiting, some will come!
2. if the are not coming i am doing a noise from the throat tik-taking
Or making an OMM OMM voice, they will be interesting in the voices
Most cautious they will arrive slowly, don’t loose your patience!!
3. Most sardos or striped sargo are living in caves inside the reef when they
Feel a threat the enter inside the caves so you can wait in ambush in
Front of the caves (hold good your breath)
The big sargos are big because they are cautious! Remember that!
Same way with the noise from the throat work for lobinas
(This can explain MEMO better then me
