if you can get some grubs (larva) of the dung beetle, called ghooiya, over here.. you can get the bigger ones.. at the same place you get yours.. ciao.
Now this is when I start thinking angling can get as insane as it does!....... Most bongs swear by ant eggs and I've never ever seen them!!!!..... Now I need to look for the larva of dug beetle called ghooiya! it sounds as though your calling ghoo in marathi like ghoo hya real fast..... kidding...... now if you may be as kind enough and also let me know where I can find this ethereal substance so I can try and catch a bigger murrel! if not this have you ever seen or know where to find ant eggs..... after catching the murrel I'm not so keen on hooking one unless ts bigger or say atleast 2 kgs but what I am keen on is hooking a good carp from the river which has a current and can't keep a feeder in it and I've heard ant eggs when mixed with bait create the effect for them carps! so hoping on getting some inputs there..... its been sometime we went fishing..... lemme know if your up to hitting a water body sometime.....
and btw whoever told you it was palm sized must be some giant as I'm six feet tall with long hands and the fish was an inch close to my elbow when its mouth was on the tip of my index finger...... I'm sure that's a lot more than an average palm size.... but then again..... I'm not so affluent with fishing terminology as such..... newbie so..... maybe any fish unless considerably big is referred to as palm size...... or maybe the guy who told you was just jealous, I don't know who he is and neither do I wanna say anything that might sound offensive to a fellow angler.......... none the less most stories have many sides to them and we never know whom to believe unless we sit down to discuss..... and your one of the most busy men I've know so..... do lemme know if your upto hitting a water body for some fishing sometime.
