Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Rocky Neck State Park is also closed until further notice due to a brush fire. Please note that today's forest fire danger report remains at a 'very high' or 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Inland Silverside (Menidia beryllina) - Native

7 cm inland silverside.

These 3-inch inland silversides differ from the Atlantic silverside primarily by having a shorter anal fin and slightly larger scales.

Identification. Similar to the Atlantic silverside, but with a shorter anal fin (15-20 rays) and larger scales (16 scales along the sides before the dorsal fin).

Size. Commonly 2 to 2.5 inches. State survey max. size 4.2 inches. Max. reported size 5 inches.

Distribution. Atlantic and Gulf coasts from Massachusetts to Texas. They likely occur along the entire Connecticut coast-line, where they are typically common to abundant.

All maps created in 2009. See CT DEEP Fish Community Data for updated distributions.

Habits. More likely to enter fresh water than Atlantic silversides, although they will rarely travel far from salt water. Prefer quieter water and sand or gravel bottoms of estuaries and streams. Typically found in schools near the surface. Can be caught with small-mesh dip net or seine.

Comments. Also known as “tidewater” silverside. They are less common than and very difficult to distinguish from the Atlantic silverside without magnification.
