Identifying predators of the SW Atlantic Patagonian scallop Zygochlamys patagonica using stable isotopes

“…In a fisheries context, elimination of predators (by any means) has been frequently recommended, and in several cases enforced in scallop management program (Golikov and Scarlato, 1970). Starfishes have been the most frequent target but often any predator caught in the fishing gear is destroyed .…”

“…It is basic for any community-based management strategy to understand the relationships between the main components of the food web and the effect of harvesting on these relationships (mainly on predator-prey relationship). There are even management actions that are based on community interactions, mainly the control of predator populations (e.g., culling of marine mammals, Corkeron, 2004; removal of starfishes, Golikov and Scarlato, 1970). These biological interactions, however, are hard to determine within benthic marine communities of deep waters because it is difficult or impossible to use direct observations and because indirect techniques such as gut content analysis are often unreliable as indicators.…”

“…In this context, a community-based management of the Patagonian fishery implies the identification of main predators and the effect of the fishery on predator-prey interactions. Eradication of predators has been frequently recommended for scallop fisheries (e.g., Golikov and Scarlato, 1970) with starfishes being the most frequent target (Arima et al, 1975). In the Patagonian scallop case, there are several potential predators in the fishing beds, including starfishes, gastropods and demersal fishes (see Bremec et al, 2000).…”
