Atlantic silversides


The Atlantic silverside (Menidia menidia) also known as spearing in the north east of the United States, is a small species of fish from the West Atlantic, ranging from the Gulf of St. Lawrence in Canada to northeastern Florida in USA. It is one of the most common fish in the Chesapeake Bay and in the Barnegat Bay. They are a common subject of scientific research because of their sensitivity to environmental changes.

The fish is about 15 cm (5.9 in) long, mostly silver and white. It eats smaller (biotic) animals and plants – small crustaceans, algae, annelid worms, shrimp, zooplankton, copepods, amphipods, squid, and insects.

The Atlantic silverside’s predators are larger predatory fish – striped bass, blue fish, Atlantic mackerel – and many shore birds, including egrets, terns, cormorants, and gulls.

The abiotic factors the Atlantic silverside needs to survive varies for populations of fish based on their geographical location. A rule of thumb for the species includes an average temperature of 70 °F (21 °C), a salt content of the water ranging from 0 to 37ppt (Tagatz and Dudley 1961), and a well-mixed body of water to prevent hypoxic conditions.

The Atlantic silverside’s habitat is generally near the water’s edge. They are mostly found swimming in brackish waters, such as in the mouths of rivers and streams that connect to the ocean. These small schooling fish have been seen to gather in seagrass beds, which can harbor the nearly defenseless fish some form of shelter from predation as well as provide safe haven for spawning. During winter, most Atlantic silversides swim in deeper water to avoid cold/low temperature. During the summer, most are found in the shallows along the shoreline.

The Atlantic silverside’s defense is to hide in seagrass beds. They are also quick swimmers and their coloration of silver and a little white makes it confusing to predators to determine the direction the fish are heading. The silverside's strongest form of defense is the strength-in-numbers strategy, where fish will school in large numbers to diminish their chances of being the one picked off by a predator.
