Bopanna is as nice a guy as you will meet, a personal friend I can trust, and what he says is the gospel truth: this idiotic "ban" will be the surefire death knell of the masheer and every other species of fish on that stretch of the Cauvery.
I have been fishing regularly from Dodhmakli to Sangam and all points in between since '91, and my fishing buddies have been doing so a lot longer. Not once in all those years have we ever seen a Forest Officer patrol that stretch. What we have never failed to see, and often apprehend, are poachers in daylight hours with nets and dynamite. This is inspite of the Jungle Lodges' Anti-Poaching camps. With this ban and a resultant sharp decline in their budget any anti-poaching efforts will be history. It will then be open season for poachers from far and wide. The village of Jagri is teeming with these types. I know. My ghillie at Bheemeshwari, Selvaraj, was a master at this, as are most of the ghillies. My ghillie in Galibore, Karie, is even better. Guess what, when these guys are suddenly unemployed, as they surely will be, they're going to revert to their old ways in a heartbeat. They're now better equipped, have some disposable income, and will be raring to go.
Hunting, in the US, has pumped millions each year into wildlife management. As a result there is more wildlife now than when the Native Americans held sway. So stop being intoxicated with your penchant for disinformation, read the writing on the wall, do your homework, and if you love wildlife, fishing, and the outdoors you will oppose this vengeance-driven ban. And you know what? I don't even fish for masheer at all.
