Tenualosa ilisha, one of the Least Concern (LC) Freshwater Fishes of Bangladesh

A Least Concern (LC) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as likely lowest risk, widespread, abundant taxon and does not qualify for a more at-risk category.

According to IUCN Bangladesh (2015a, b) two hundred fifty three Freshwater Fishes were assessed by IUCN Bangladesh. Threatened Categories are concerned nearly one fourth (64 species) of the species are under threat, among them 9 (3%) Critically Endangered, 30 (12%) Endangered, and 25 (10%) Vulnerable. This has been followed by 27 (11%) species as Near Threatened. Outside the purview of the Threatened and Near Threatened Categories, there are 122 (48%) species that were assessed as Least Concern and rest of the 40 (16%) as Data Deficient.

NB: Species are classified by the IUCN Red List into nine categories, set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. The term “Threatened” is a grouping of three categories such as Critically Endangered, Endangered, and Vulnerable.

Categories Criteria
Extinct (EX) No known individuals remaining
Extinct in the wild (EW) Known only to survive in captivity, or as a naturalized population outside its historic range
Threatened
Critically endangered (CR) Extremely high risk of extinction in the wild
Endangered (EN) High risk of extinction in the wild
Vulnerable (VU) High risk of endangerment in the wild
Near threatened (NT) Likely to become endangered in the near future
Least concern (LC) Lowest risk. Does not qualify for a more at-risk category. Widespread and abundant taxa are included in this category
Data deficient (DD) Not enough data to make an assessment of its risk of extinction
Not evaluated (NE) Has not yet been evaluated against the criteria
