摘要：Longnose dace (Rhinichthys cataructae). red shiner (Cyprinella futrensis), and green sunfish (Lepomis cyanellus) were fixed in 5% and 10% fonnalin and 70% and 95% ethyl alcohol to determine fixative effects on total length (TI,). Total length reduced over the first 24h for all species (P<0.0001) but then stabilized. Longnose dace and green sunfish TL reduction was less for 5% formalin than for either 70% or 95% ethanol (both P<0.0001), whereas the fixative solution had no effect on red shiner TL (P=0.347). A greater percentage of change in TL was observed in green sunfish and red shiner than in longnose dace, suggesting that body form (compressiform vs. fusiform) may affect shrinkage rate among adult stream fishes.
