Notice

The Fish Index of Biotic Integrity for non-wadeable sampling sessions is currently calculated using the standard wadeable stream FIBI metrics. The results for non-wadeable sessions are typically lower than would be expected at a similar, wadeable stream, but are included for comparison purposes.

Non-wadeable streams score lower due to the difficulty of sampling wide, deep rivers. Boat shockers are also selective towards larger fish species, as it is more difficult to collect smaller fish species, such as minnows, in an non-wadeable environment.

FIBI Score Explained

Sites that score between 51 - 70 are considered good. Fish (excluding tolerant species) are fairly abundant to very abundant. If high numbers are present, intermediately tolerant species or tolerant species are usually dominant. A moderately high number of fish species belonging to several families are present. The three most abundant fish species typically comprise two-thirds or less of the total number of fish. Several long-lived species and benthic invertivore species are present. One or more sensitive species are usually present. Top carnivore species are usually present in low numbers and often one or more life stages are missing. Species that require silt-free, rock substrate for spawning or feeding are present in low proportion to the total number of fish. Fish condition is good; typically less than 1% of the total number of fish exhibits external anomalies associated with disease or stress.

This location has been classified as a survey site. Survey sites are compared to reference sites within the same ecoregion. A reference site represents natural stream qualities that are least disturbed by human activities within the watershed. Reference sites are grouped by ecoregion to establish a benchmark against which these test streams are compared.

EcoRegion Comparison

Scores for a sampling session are compared against reference sites within the same ecoregion:
