More and more all over the world anglers practice “No Kill” or “Catch and release” and Portugal is no exception to this phenomenon, existing among us an already considerable number of people practicing it and with tendency to expand.
It's a discipline where after the catch the fish is weighted, measured, photographs are taken and it's kissed (you can pass on this part).
Since you're not going to eat the fish, they should be treated with all respect and released directly back in the water with no mistreatments, preferably not even keeping them in a net.
One must be careful while handling the Carps to avoid hurting them and remember that a Carp caught today with 10 lbs can be caught next year with 14 lbs and so on … so you must take the hook out carefully, avoid contact with the ground and clothes and, if she has swallowed the hook, you should better cut the line the closest to the hook and just leave it there because he will come off on his own or finish by rusting, causing less damage than trying to pull it out.
ONE MUST RESPECT THE FISHING SPOT
I never saw an angler going out for a session that doesn't cary in the middle of his stuff at least one plastic bag.
This plastic bag is ideal to collect all the garbage that we create along a fishing journey; drink cans, other plastic bags, bottles, left over of fishing line and so on that, being a plastic bag ready to receive them, then, at the end of the journey it doesn't take much to take it back and leave it on a garbage container that we'll find on the way back home.
It weight's less the garbage we bring than the one we took …
Think this way: “I must leave no evidence that someone someday ever fished here …”
Nature will be happy with your attitude !!!
Along with her the land owner …
There are quite a large number of private dams with beautiful Carps where fishing is not allowed just because the land owner got tiered of the mess fisherman left behind … Think about it !!!
RESPECT THE OTHER
When you reach a spot and there is already someone fishing you should leave him space, don't go seating over him.
Avoid unnecessary noise … This is valid the other way too; if you're alone fishing you can do the noise you wish but if some other angler comes … respect him the same way you want him to respect you …
