  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • Provisional Checklist of Canadian Freshwater Fishes
    PROVISIONAL CHECKLIST OF CANADIAN FRESHWATER FISHES Information Leaflet Department of Ichthyology and Herpetology Royal Ontario Museum July 1967 INTRODUCTION The following provisional list of Canadian freshwater fishes is not intended for publication but has been compiled as an aid in the preparation of a comprehensive text on Canadian freshwater fishes, being sponsored by the Fisheries Research Board of Canada. Notice of the preparation of such a text was provided in a letter dis- tributed in the fall of 1966, and in which it was indicated that documents of this kind would appear from time to time, and would be circulated to those who indicated an interest in the project. This list includes 185 species in 25 families. For a number of species, changes in nomenclature have occurred since publication of a previous list by Scott (1958). Such changes are designated in the present list by the wording, "Formerly..." This list is in general accord with Special Publication No. 2 of the American Fisheries Society both in useage of the scientific and common names and in the order of families. For convenience species are listed in alphabetical order within the genus. At this stage, we have chosen to avoid including subspecific designations even when the two forms are known by distinct common names. This can be altered if it becomes apparent there is real merit in separating some forms into two entities. We earnestly solicit your criticisms on any and all aspects of this list. Simply write your criticisms directly on this list, adding additional sheets if necessary, and return it to us.

  • Strategy for the Establishment of Self-Sustaining Atlantic Whitefish Population(S) and Development of a Framework for the Evaluation of Suitable Lake Habitat
    Canadian Science Advisory Secretariat Maritimes Region Science Advisory Report 2018/045 STRATEGIES FOR THE ESTABLISHMENT OF SELF- SUSTAINING ATLANTIC WHITEFISH POPULATION(S) AND DEVELOPMENT OF A FRAMEWORK FOR THE EVALUATION OF SUITABLE LAKE HABITAT Atlantic Whitefish (Coregonus huntsmani) (Source: DFO 2009) Figure 1. Global distribution of Atlantic Whitefish. Context: The Atlantic Whitefish (Coregonus huntsmani) is an endangered species that is at high risk for global extinction. The species global distribution has been restricted, for at least the past three decades, to three small interconnected lakes in the upper Petite Rivière watershed in southwest Nova Scotia. The continued survival of Atlantic Whitefish is now further threatened by illegally introduced invasive piscivorous fish species (Smallmouth Bass (pre-2003) and Chain Pickerel (2013)) within this remaining habitat. Range expansion, the establishment of additional self-sustaining populations outside the currently occupied habitat in the Petite Rivière watershed, is identified as the distribution objective of the Atlantic Whitefish Recovery Strategy and could also prevent extinction. In spring 2017, three options in support of survival and recovery of Atlantic Whitefish were considered by Fisheries and Oceans Canada (DFO). Options included: simple translocation, translocation with temporary holding, and the establishment of a new propagation program at a DFO Biodiversity Facility with the option of translocation with temporary holding approved. This option would see Atlantic Whitefish, captured from the Petite Rivière Lakes, transported to a DFO Biodiversity Facility for short-term holding, before being released into new non- natal habitat. However, insufficient numbers of Atlantic Whitefish are available from the wild to provide a reasonable likelihood of success of this option at present.

Class under: Oncorhynchus (.S25) Works on ciscoes, salmon, trout, and whitefish covering species which belong to more than one genus but which fall collectively under one of these common names will be classed under the Cutter for the common name. Made-up example: Title: Guide to trouts. Subjects: Cutthroat trout (Oncorhynchus clarkii), brown trout (Salmo trutta), and lake trout (Salvelinus namaycush). Class under: “trout” (.S216) The fishes are arranged by scientific (Latin) nomenclature. Only the most current standard scientific (Latin) name is given. Obsolete and debated scientific names are numerous. Adjustments to taxonomical classification are not uncommon, including reclassification to a different genus. The previous or alternative versions of common (vernacular) names are shown. Be aware that some market names (those used commercially) are scientifically incorrect.
