I can see you get your info from text books
If you are trying to imply that my knowledge only comes from text books you are wrong! I fish and dig bait all over the British Isles and have seen tellins in many places in amongst worm beds. I observed these shellfish long before looking them up in a text book.
However this is getting off the point. You made that statement that " it is true that the fish have come to the worm beds to feed on worm as some worm will show themselves when covered by the tide some will even leave their burrow altogether and go with the tide to new ground
Ive never seen any evidence to support this statement.
As Dabcatcher said what looks like a flat expanse of sand or mud, doesnt just contain worms. Theres a whole miriad of things that live in and on that sand or mud.
I agreed and gave examples of harbour rag and the Baltic tellin theres lots of others besides.
You then made the statement the gut of fish has very high acid levels an break down meals quickly worm wont be noticed often as it gets broken to a brown sludge very quick.
I then gave examples where worms were found in the stomachs of fish.
You stated quite obvious that this fish had only just picked the worm up before being caught
Now Its also obvious to me that if fish were feeding over lug beds on lug then fish caught from those areas would only just picked the worm up before being caught and would have undigested lug in their stomachs.
Ive seen lots of food items in fish caught over worm beds including Baltic tellins but I cant recall ever finding lug!
So we are back to my original question What evidence have you got to support these statements?
If youve got any evidence I would be interested to hear about it.
