Appendix B. Meristics of foreign nonindigenous cyprinids and selected hybrids.

       This appendix contains meristic characters for the eleven foreign nonindigenous cyprinids treated in this guide, as well as some of their hybrids. Each table presents meristic information from a number of reports, generally ranging over a wide geographic area (often including data from populations in both native and non-native areas). Because the soft rays of the dorsal and anal fins are often difficult to discern, many authors typically report only a single number, which includes one unbranched ray plus all branched rays. We have reproduced these counts as given by the original authors. In contrast, some authors give counts for both unbranched and branched rays in the fins. The format of these counts has been standardized by using Roman numerals to indicate unbranched rays followed by Arabic numerals (in parentheses) to represent the number of soft branched rays. Gill-raker counts are based on the first (outer) gill arch. All gill rakers are counted, including small rudimentary ones. Some authors give either upper and lower limb counts, or inner and outer (anterior and posterior) counts, and we have reported those data where available. For more information on reporting meristics, see “Methods.”
