It's a nice idea. However i don't think that the fish population in the Cauvery are going down (masheer), it's just that the bigger fish have become wiser / moved base to other quieter parts of the river.
The dynamiting incedents have certainly decreased over the years. I remember times when gangs of poachers would drop their load into the water just next to me, even though i had asked them not to. Fishing alone, there was not much i could have done.
All that has stopped now, so the fish stocks are definately on the increase, but as has happened in all over fished waters, the same is the case here. The fish are getting smarter.
In any case, abideing by any rules, would be the moral responsibility of every angler out there as i can't see anyone enforcing this in our country.
By the way the murral eat as many fry or more than other predatory species, but are slow breeders or so i hear, and therefore deserves our consideration. The murral stocks definately have dimnished to a great extent in the Cauvery.
Anyone fished murral market this year with and catch anything big ?
I would be surprised to hear a "Yes"!
I have noticed several posts where anglers mention that catches are going down in the Cauvery and that bad management by certain fishing outfits/ over commercailization/ govt. groups has resulted in fish population going down etc.
However, very often, anglers keep every single fish that they catch thats "legal". i.e thats not a masheer. Large murral and kept for the pot as are every other species.
The point Iam trying to make here is that there is no "catch limit" or" size limit" charter if you will in existence in India for "ethical" anglers.
It might not be the law i.e no ones going to throw you in jail if you dont follow the same but there is no charter/ or guidelines that encourages anglers to release (or keep) fish that they catch.
For example Tilapia are an introduced species that preys on endemic species and should be kept for the pot on principle whereas large murral in lakes should likely be released.
I am not an icthyologist that knows much about the species I catch/ their breeding seasons etc but maybe this "catch and size limit charter" should be drawn up and made available at the fishing camps for "voluntary observance".
A lot of people keep fish, including carp full of eggs as I have seen, out of ignorance. A chart with breeding seasons, size limits and list of non endemic "keeper" fish might help anglers in deciding whats kept or released. Objective: to help in the preservation of Native Indian fish species as well as angling locations for generations to come.
