i have talked to knowledgeable people on this before,now they may not be as schooled as moose or others. in regards to the fish filling their bladder by going to the surface,if he goes up and and fills it how does he go back down?seems about the equivalent of carrying sand in a screenwire bag,won't work very good.don't they deflate to go down?i was under the impression,from a guide in destin,when i asked about snapper we were catching.the bladder has gas in it all time and the pressure he is under is what enlarges the bladder,or deflates,whatever he needs.now he said yes they will go down if you pop it and may live but it is like filling an inner tube with a pinhole in it for awhile until it heals,if it does before he dies.i guess it seems to me if you pop it,it don't work right,it would be swimmin like he was very drunk and that seems stressfull.
hey moose thanks for all the input,i learn something from evry post,but please try to use redneck terms where possible..
by the way i may be way off on all this but i felt the same about the needle.you're making ahole for water and stuff to get in where it shouldn't be.
