The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Tanichthys albonubes Lin, 1932

Common name: White Cloud Mountain Minnow

Taxonomy: available through www.itis.govITIS logo

Native Range: First discovered at White Cloud Mountain (also known as Mount Baiyun or Baiyunshan) a few miles north of the city of Guangzhou, Guangdong Province, China and thought to be restricted to the surrounding Pearl River Delta region. Unfortunately it has probably been extirpated from that locality; the “mountain” is actually a collection of 30 or so peaks and is now a very popular tourist resort complete with cable car access, hotels, and public parks. Between 1980 and 2001, the species went unrecorded in nature, leading to fear of its extinction (Seriously Fish, 2012b).

Ecology: This species inhabits clear, slow-moving brooks with thick weed growth (Chan and Chen, 2009). The White Cloud Mountain minnow is cold water tolerant fish often kept in aquaria. Although the nominal temperature range for the species in the wild is 18–22 °C, it can survive water temperatures down to 5 °C (Froese and Pauly, 2012). It feeds on plankton, meiobenthos and larvae of aquatic insects. This species spawns several times a year, from March to October, on plants (Cui, 2011).

Means of Introduction: Aquarium release.

Status: Unknown.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
