FIBI Score Explained

Sites that score between 0 - 25 are considered poor. Fish abundance is usually lower than normal or, if fish are abundant, the collection is dominated by a few tolerant species. The number of native fish species present is low. Sensitive species and habitat specialists are absent or extremely rare. The population is dominated by just a few ubiquitous species that are tolerant of wide-ranging water quality and habitat conditions. Pioneering, introduced and/or short-lived fish species are typically the most abundant types of fish. Fish collected at poor sites often have a higher than normal occurrence of external physical anomalies.

This location has been classified as a Rejected Reference Site. This site was a Reference Site at one time, but subsequent biological assessments have determined that this site no longer meets the qualifications of a Reference Site.
