No room for dessert: A mechanistic model of prey selection in gut‐limited predatory fish

open access: yesFish and Fisheries, Volume 21, Issue 1, Page 63-79, January 2020., 2020
Abstract Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey items. Digestion times of large prey are usually longer than handling times, and gut processing limits feeding rate at high ...
