However, no specific management practices are in place to protect the Brook Stickleback.

Fish have been observed to be the most successful predator of the Brook Stickleback.

This could highly affect the spawning season for the Brook Stickleback species.

The brook stickleback does have active competition mostly from minnows, but feeding times are different, along with diet.

Yearly samples would be most beneficial since the Brook Stickleback is an annual species.

Intraspecific and cross-superorder responses to chemical alarm signals by brook stickleback.

Certain large invertebrates, birds, mammals, and fish all prey on the Brook Stickleback.

However, this does not mean the Brook Stickleback is immune from human induced changes to the ecosystem dynamic.

Current management practices for endangered species of fish should continue their progress because they could be having indirect effects on protecting the Brook Stickleback.

However, Brook Stickleback feed on vascular plant material, as well as algae.

The Brook Stickleback lives in habitats of all sizes from lakes to streams to sinkholes.

Keeping certain invasive species out of lakes occupied by the Brook Stickleback could ensure a protect environment from predators.

Though the brook stickleback is not considered a threatened species, deforesting and changing waters are altering ecosystems of the species.

Nebraska does have Brook Stickleback populations, but they are generally found in small streams in the northern portion of the state.

With its armored plates and spines, the Brook Stickleback has well adapted itself to the current predators it encounters.

Harvesting of trees around riparian environments is having a large effect of the stream ecosystem where the brook stickleback resides.

With this protection, as well as advanced anti-predator behavior, the Brook Stickleback is only a minor prey item.

The Nature Conservancy has listed the Brook Stickleback as level S3 (vulnerable).

Alteration of stream dynamics could also lead to a change in predator frequency, thus exposing the Brook Stickleback to unforeseen predators.

However, invasive species with better-adapted predatory behavior and shell crushing mouth construction could decimate certain Brook Stickleback populations.

The Saskatoon Lake is home to Brook stickleback, brook trout and rainbow trout.

Intra- and interspecific avoidance of areas marked with skin extract from brook sticklebacks (Culea inconstans) in a natural habitat.

Brook Stickleback eggs can be cannibalized, as well as consumed by rainbow trout (Oncorhynchus mykiss).

The Brook Stickleback can be found from the northern parts of the Canadian interior all the way down to southern reaches of the United States.

However, ninespine stickleback habitat exists in the pelagic zone, while the brook stickleback occupies the littoral zone.

The Brook stickleback (Culaea inconstans) is a small freshwater fish that is distributed across the US and Canada.

For example, young brook stickleback (Culaea inconstans) are more likely to be caught in minnow traps that have been baited with conspecific skin extracts than adults (Chivers and Smith 1994).
