Gastropod relevance in predator-prey interactions on a benthic shallow sandy ecosystem at Mar del Plata, Argentina (38°S)
The shallow sandy marine subtidal ecosystem off Mar del Plata, Argentina, is the scene of multiple fisheries activities, in particular the prawn-shrimp Artemesia longinaris and Pleoticus muelleri grounds. We examined the δ 13 C vs δ 15 N isotope signatures of 22 species commonly found in the area in...

The shallow sandy marine subtidal ecosystem off Mar del Plata, Argentina, is the scene of multiple fisheries activities, in particular the prawn-shrimp Artemesia longinaris and Pleoticus muelleri grounds. We examined the δ 13 C vs δ 15 N isotope signatures of 22 species commonly found in the area in order to understand how this ecosystem supports the fishery, with special emphasis on imposex-Affected gastropod populations. Our results indicate that the main food source for Olivancillaria urceus and Buccinanops monilifer were bivalves and crustaceans. Buccinanops duartei and Olivancillaria carcellesi feed on bivalves and also on macroalgae. These findings indicate, for the first time, a slight selectivity of some of the gastropods studied for local drifted algal sources and how gastropods may scavenge available food from by-catch returned to the sea. The fishes Urophysis brasiliensis and Callorhynchus callorhynchus appeared to be the top predators of this area with B. duartei and O. carcellesi constituting important components of their diet.
