Book Description
The rosyface shiner, Notropis rubellus, is a small cyprinid fish (or minnow) with a Canadian distribution from the upper St. Lawrence drainage west through southern Ontario to south-eastern Lake Superior. There is also a separated population in the Whitemouth-Birch River system of southern Manitoba. This report provides information on the fish's geographic distribution, protection status, population sizes and trends, habitat, general biology, factors limiting its population and affecting its habitat, and the special significance of the species. Concludes with an evaluation of the future of the species in Canada and a proposed status designation for the Manitoba population.

Book Description
Notropis heterodon, the Blackchin Shiner, is a threatened species in northeast Illinois. Historical sites and recommended sites were sampled for presence or absence and habitat data. Notropis heterodon showed a decrease in range by 61%, and a preference for habitats containing sand and vegetation. Notropis heterodon exhibited an opportunistic strategy with reproduction occurring from late May through early August. Length frequency analysis show N. heterodon reaching sexual maturity in the 1+ age group and possibly living to 2+ years. Notropis heterodon had a diet consisting of four main contributors: bosminids, chydorids, ostracods, and dipteran adults, on which N. heterodon feeds on primarily in the morning and at night. The Blackchin Shiner is restricted to the extreme northeast corner of Illinois and requires clear lakes with submerged vegetation and a sandy substrate. These three requirements of the species can be applied to the natural glacial lakes in order to save existing populations.

Book Description
The blackchin shiner (Notropis heterodon) and the blacknose shiner (Notropis heterolepis) are two of 34 native cyprinid fishes found in Ontario. This report describes & illustrates the early developmental stages of these cyprinids, collected over the past 15 years in vegetated areas at the shores of Lake Huron and Lake Erie. Morphology, meristics, pigmentation, and illustrations of age-zero preserved fish are presented as aids to identification.
