How to Observe and Appreciate Fishes
Learn about all the ways you can watch Connecticut's many freshwater fishes!
They are sold as bait at coastal bait shops (where they are often called “killies” or “mummies”) and are popular due to their toughness and ability to survive in fresh water.
Minnows are an extremely diverse family with abundant representatives over most of the world. Learn about all the minnows who call Connecticut home!
Ninespine stickleback males build little tunnel-shaped nests out of bits of vegetation.
Mudminnows are a small family of the Northern Hemisphere that look similar to killifish and minnows, but are actually more closely related to pike.
Mullets are torpedo-shaped fishes with horizontal mouths.
The pupfishes and killifishes are very similar and were once included in the same family.
Both marine and freshwater killifishes are distributed throughout Central and Eastern North America from southern Canada to the Yucatan, including Cuba and Bermuda.
Hybrids are more common in unfished or lightly fished waters, most likely because they are easier to catch than the parent species and are thus removed more quickly from heavily fished waters.
Also known as “tidewater” silverside. They are less common than and very difficult to distinguish from the Atlantic silverside without magnification.
