The whelk-enclosure experiment demonstrated that the predatory whelk affected not only survivorship but also growth rate of the clam.
Most of the shellfish remains in the Florida coast middens were oyster shells while shells of clams, knobbed whelks and periwinkles were present in lesser amounts.
At Strawberry Hill, whelks had higher body temperatures and higher Hsp 70 pools than those at Boiler Bay.
Predatory snails, including Oyster Drills, whelks , sponges, especially the Boring Sponges, and fish all find oysters a tasty treat.
Shellfish such as oysters, mussels, cockles, winkles, whelks and crabs were collected for food from the estuaries and sea-shores.
Overall, mussels, barnacles and whelks all had higher metabolic activities at SH than BB, whereas there was no difference in metabolic activity for sea stars.
So the 10m ropes provide an ideal home where they can remain suspended above the seabed and out of reach of starfish, crabs, whelks and other predators.
These results were obtained from experiments in the lower mid zone at each site and exposure, in which shelter and food availability (mussels, M. trossulus) for the whelks were manipulated.
People forget that Glasgow is by the sea, but I love restaurants that make something of that closeness, bringing mussels and whelks and Firth of Clyde-reared cod onto the menu.
Starved whelks were provided with empty mussel shells so that sun-exposure was similar for both treatment groups.
