Predation by Crabs, Shrimp, and Small Fish

Tidal flats are nurseries for fish and decapod crustaceans (Zijlstra 1972). The larvae are washed inshore, metamorphose, and first stay permanently on the flats, but soon start to migrate in and out with the tides. Some adults also perform tidal migrations (e.g., the crab Carcinus maenas), while in most species the adults forage mainly on subtidal benthos. Tidal flats provide the nurslings with favorable growth conditions, ample small-sized prey, and with a refuge from large predatory fish.
