Sabyasachi- I do speak the language. I met them three or four times to speak to them. Some fishermen see the bycatch as something they can't avoid since they can't predict the aggregations. This is pertaining to the accidental capture of juveniles. About the release of adults- this would be harder to achieve. When one encounters a deadly animal (that too a snake with aggressive habits) regularly in the course of a days work, it would be hard not to fear it. When I spoke to them about releasing snakes rather than killing them, it seemed a ridiculous topic to them, and to be frank I understand why. That is the reason I find this hard to deal with. The only way i see education being effective in this case is if the cause is endorsed by one of their own. Laws and enforcement won't help as that would imply loss to livelihoods.
