bcfishpass

bcfishpass is a collection of scripts to create and maintain an aquatic connectivity / fish passage database for British Columbia.

The generated bcfishpass database:

• tracks/models natural barriers to fish passage (waterfalls, steep gradients, other)

• tracks/models anthropogenic barriers to fish passage (dams, road/rail stream crossings, other)

• models accessibility of streams to given fish species based on natural and anthropogenic barriers

• models potential spawning and rearing habitat for select species based on stream gradient and discharge

• provides data for prioritization of stream crossing sites for assessment and/or remediation

• provides a method for visualizing and quantifying fish passage issues in BC
