sandymount worms

hi all,

i was digging for lugworm in sandymount the last three days, looking forward to a spot of kerry beach fishing over the b/holiday week, anyways i parked the motor beside the twin towers and off i went with my fork, bucket and glove to the ususal spot i always did for them, in and around the stream there.
What struck me on reaching the worm beds was how few worm casts there were, i have been digging in the same area for a few years and normally there are lots of casts tobe seen with lots of big juicy blow lugworm mostly, with a few black lugworm to be had here.
The worms were none existant in this area so i went beyond the stream towards the sandymount direction,i eventually dug more black lug worm and less blow worms, than i would ususally get digging by the stream however the black lug worm were smaller in general than the worms i get by the stream.
Has any body else noticed the reduced worm numbers in sandymount or would have any theory as to why they seem to be reduced in numbers here.

personally I dont waste my time no more digging were u dig at the stream its serious hard work and a waste of time imo the lug beds there and rag beds are ruined

I always find it harder to dig this time of year

Well whatever the reasons it is going to be seriously hard work to get any lug at the stream area, so further into the sandymount area I will have to go looking in future
