a year ago we tried fishing but that was on Cornich near the coffee shop, im not sure in The pearl since i saw most of the place that fishing is not allowed, a friend of mine was fishing somewhere in W Hotel(westbay), someone reported to the police and they caught him and got jailed for 24 hrs along with the QAR 1000 fine, be careful bcoz some places here even its not allowed they dont put signs for restriction
