Pimephales Notatus

Bluntnose minnows (Pimephales notatus) can be recognized as individuals by the pattern of spots, most of which are caused by trematode cysts, on their dorsal surfaces and pectoral fins. Nesting males were captured, photographed, and released on several occasions. The pictures, as well as preserved collected specimens, allowed detailed study of the patterns of spots and enabled identification of many individuals. The behavior of the fish indicated no serious disturbance by the procedure.

We compared the minnow assemblages of Adirondack lakes with top piscivores with those of lakes having similar physiochemical and biotic characteristics but no top piscivores using a subset of data collected from 1984 to 87 by the Adirondack Lake Survey Corporation. Native minnow richness in lakes with top piscivores was about one third that of lakes without piscivores, with piscivore assemblages dominated by introduced species such as northern pike (Esox lucius), largemouth bass (Micropterus salmoides), and smallmouth bass (Micropterus dolomieu). There was strong evidence that at least four minnow species, including creek chub (Semotilus atromaculatus), northern redbelly dace (Phoxinus eos), blacknose dace (Rhinichthys atratulus), and common shiner (Luxilus cornutus), were less likely to occur in lakes with piscivores; for a fifth species (pearl dace (Margariscus margarita)), the evidence is suggestive but not as strong. Of 13 minnow species, only for two nonnative species (bluntnose minnow (Pimephales notatus) and golden shiner (Notemigonus crysoleucas)) was there strong evidence that their occurrence was unaffected by the presence of introduced piscivores. These results add to the growing body of evidence that the introduction of top piscivores to small temperate lakes puts native minnow communities at high extinction risk.
