Abstract: 

Shrimp populations were monitored at approximately 3 week intervals to determine the variability in numbers and sizes of each species in response to disturbance and seasons.

Methodology

Methods: 

20 pools along the reach were identified and include as much variety in pool morphology as possible. Due to variablity in flow conditions not all of the pools were sampled at each time point. 1-4 minnow traps, depending on pool size, were baited with Moist Meals cat food (chicken flavor) and placed in each pool late in the afternoon at approximately 3 week intervals. The reach was broken into two halves and the upper section trapped one day followed by the lower section on the next day. The traps were checked in the morning; all shrimp caught were identified to species. Carapace length and if the shrimp was gravid were recorded. Shrimp were returned to the pool they were caught in after all data was collected. Note: Reach starts where the trail from the Sonadora bridge on Hwy 186 crosses the stream and ends approximately 125 meters upstream.
