species of fish From Wikipedia, the free encyclopedia
The brook stickleback (Culaea inconstans) is a stickleback that is distributed across the US and Canada. It is the only species in the monotypic genus Culaea. They are preyed upon by smallmouth bass and northern pike.
Small populations are scattered throughout the Mississippi-Great Lakes basin extending to Colorado, New Mexico, Kentucky, Tennessee, etc., but sometimes, these places don't have these freshwater fish.
The brook stickleback has a small, compressed, and oblong-shaped body with a slim caudal peduncle and a fan-shaped tail. It can grow to a length of 3 to 5 cm (1.2 to 2.0 in). It has swollen lips resembles the ninespine stickleback in appearance but only with five, or occasionally six, dorsal spines. It also lacks lateral bony plates.
The colouring is grayish or olive green throughout the year with lots of indistinct mottling. During the spawning season, males are nearly black and females have darker and lighter patches.
Culaea inconstans occurs throughout the southern half of Canada and the northern part of the eastern United States. It is one of the smallest fishes in the region.
Brackish water populations are extremely rare but possible. In Nebraska, brook sticklebacks are generally found in small streams in the northern portion of the state. They've been in Nebraska since the 1900s.
The brook stickleback is normally found in North America, but it has also been introduced in Europe. These little creatures were brought in upper drainage of the River Inn in Bavaria. In the 1960s, they were introduced alongside the genus Micropterus to Lohjanjärvi in southern Finland.
