Nursery habitat for larvae and juveniles includes littoral and sublittoral saltwater coves, coastal salt ponds, estuaries, and protected embayments. Rising temperature could also be restricting food availability by redistributing species found throughout the bay, or creating favorable conditions for new competitors of the same food source or more predators, such as summer flounder and sea robin. Natural predators of winter flounder include sharks, oyster toadfish, summer flounder, striped bass, monkfish and spiny dogfish.

This … Predators: Fish, such as striped bass, bluefish, toadfish, and summer flounder, birds, invertebrates, winter skate, and marine mammals prey on larvae and juveniles.

Winter flounder size selection Searobin selectivity for sizes of flounder prey was examined in circular tanks (1.8 m diam.×0.5 m deep) with and without sand substratum (Table 1). Starved searobins (n =12, 212–309 mm TL) were acclimated to tanks for 20 h. Predators: Fish, such as striped bass, bluefish, toadfish, and summer flounder, birds, invertebrates, winter skate, and marine mammals prey on larvae and juveniles.

Flounders will often lie in wait to feed on shrimps, amphipods, sandworms, small clams, and smaller fish. As winter flounder larvae metamorphose to benthic juveniles, preferred habitat appears to shift from the retention areas to more protected reaches either up river or embayments in the lower estuary.
