- Title
THE INFLUENCE OF BAIT DIGGING ON COCKLE, CERASTODERMA EDULE, POPULATIONS IN NORTH NORFOLK.

Jackson, M. J.; James, R.
- Abstract
The population of cockles Cerastoderma (=Cardium) edule (L.) declined drastically in the late 1950s and ’60s concurrent with intensification of digging for lug and rag worms. At Blakeney Point, where bait digging is slight, cockles remained common. A field experiment showed that digging is slight, cockles remained common. A field experiment showed that digging caused heavy mortality of cockles and probably acted more severely on smaller ones of each age group. Laboratory experiments confirmed that few cockles buried at 10 cm could regain their near surface positions and that many died. Predator exclusion did not affect cockle numbers.
