| Abstract: | Colorado squawfish (Ptychocheilus lucius), were subjected to dilutions of saline water from natural springs near Glenwood Springs, Colorado, to determine salinity tolerance and aquaculture potential of squawfish in this water. Lethal salinity to 50 percent of the fish (96 h LC50) was 13.1 g l–1, indicating that squawfish survival in higher salinity spring water was not possible. |
