I spend a lot of time in Daman so brought my beach, lure and carp gear with me from UK. The beach is shallow and dirty even at high water you need to cast a long way so unless you can pendulum cast over 150 yards forget it, even then the fishing is poor scratching out tiddlers. Shore crabs soon rob bait and hooks when I have tried close in tactics.
Low water uncovers a few spits either side of the estuaries which give you deeper water but you have to fish low water and fish on the retreat as the tide comes in. Becareful if you try this as in places the tide flows in behind you and can cut you off. I have tried all areas around Nani and Moti Daman with no great sucess, the estuary mouths fishing the best to prawn baits but again only small fish.
