1) Parts of the article are factually incorrect... the mahseer DOES NOT lay its eggs in sand... its spawns on shingle... loose, disturbed sand smothers the roe and wipes out entire batches of fertilized roe...
2) This problem is not only confined to the Cauvery, but is a nightmare in every mahseer river in the country... from Himacal to Karnataka and MP to Assam... In Himachal too, the government his put checks and balances into place, but unfortunately like everything else, these are only on paper. I'd like to see someone make the effort of trying to stop these guys mining along the rivers and come back with thier hide intact. 3 weeks ago a guard with the HP fishries dept had his head split open with a bamboo staff because he tried to stop illegal mining in a spwaning nulla...
to add to it all, most mining operations are run in a nexu with the local politicos... which lowly guard in his right mind will go against the mighty MLA?
The mining cannot be stopped... it is the cost of development... the govt. is for it... the only people who can regulate it are the courts, like they are doing here in HP... educated people... go file a PIL!!! don't jut sit and read papers and shoot the s**t!!!
Something as damaging as mining is dynamiting.... gelatin sticks can be got hold of easily ... go back to chem class in high school and you'll remember the recipie for ammonium nitrate... the bombing of the rivers carries on blatantly!!! and No, you won't see it happen, cause it does not happen on saturday and sunday, when there are witnesses from the city... it happens on weekdays, when we all are in our air conditioned offices and the natives are happily going about their business!!!
