We documented the spawning distribution and male mating tactics of sympatric anadromous rainbow trout Oncorhynchus mykiss (winter steelhead) and resident rainbow trout in the Calawah and Sol Duc River basins, Washington. Snorkel surveys and in situ behavioral observations were used to determine the spatial and temporal distribution patterns and male mating tactics of .

Underwater Methods for Study of Salmonids in the Intermountain West Russell F. Thurow If minimum criteria are met, underwater observa-tion has advantages for sampling fish populations.

Snorkeling is feasible where environmental condi-tions such as deep, clear water of low conductivity may limit the effectiveness of electrofishing (SchillCited by: This guide describes underwater methods using snorkeling gear to study fish populations in flowing waters of the Intermountain West.

Teams of two or more persons swim downstream in rivers or streams identifying and counting fish. Snorkel surveys are accurate, cost- effective, and do not have a negative impact on native salmonids or the environment.

In small streams, one snorkeler counts fish in a single pass, zigzagging through an entire channel unit while moving upstream.

The dashed line represents the approximate path of the snorkeler who counts fish left and right (from Thurow ). In wider streams, two snorkelers count fish in a channel unit. The objective of this study is to develop a simplified applicable assessment model to evaluate habitat conditions for selected target fish.
