Electrical Responses

The effects of mercury and copper on the olfactory response of rainbow trout (Salmo gairdneri) were studied by perfusing HgCl2 and CuSO4 solutions through the olfactory organs while recording the olfactory bulbar electrical responses to the standard stimulant, L-serine.The olfactory response was depressed during exposure to mercury and copper. The lowest concentrations of mercury and copper needed to cause appreciable effects within 2 h were estimated at 0.10 and 0.008 mg/liter, respectively. The depression increased with increase in the concentration and exposure time of the heavy metals. Recovery of the olfactory response was slower with higher concentrations and longer exposure.The method is rapid, accurate, and sensitive, and can be applied to other toxic chemicals and fish species.

Spawning Streams

A four year field study was conducted on rainbow trout (Salmo gairdneri) spawning in the inlet and outlet of Loon Lake. Young and adult trout were trapped and marked in both streams. About 5000 fish spawn in the outlet between mid-March and June; about 22,000 spawn in the inlet between late April and July. Outlet young either enter the lake by late summer or overwinter in the stream and enter the lake next spring or summer. Most inlet young enter the lake in their first year. Return as adults, of fish which had been clipped while entering the lake as young, indicated that about 94% of fish originating from each end homed to their parent stream. Because of the large number of inlet spawners, about a quarter of the outlet spawners are strays which had hatched in the inlet. Recovery of marked fish, movement of adults within the lake, and experimental transfer of adults and young between streams, all indicate that inlet and outlet spawners do not differ genetically in their responses to current. The biological and applied significance of homing, and its possible mechanisms, are discussed.
