Summary 



Standard sampling and data analysis methods for this indicator are shown to be compatible with the proposed 

 plot design and monitoring framework, and are based on standard techniques for documenting stream fish 

 assemblages. Possible constraints associated with the proposed plot design using the monitoring framework 

 include site accessibility and consistency among crews. Equipment and technical expertise requirements are 

 defined, and include the need for experienced fisheries biologists during initial phases of a monitoring program 

 and for data analysis and interpretation. Field methods used for the indicator have little impact on either fish 

 populations or habitat, and are compatible with an integrated sampling regime for multiple indicators. A pilot 

 study was performed to determine the optimal stream length for sampling (i.e., to assure that the stream 

 length sampled is sufficient to obtain at least 90% of the fish species inhabiting the reach). 



Guideline 4: Logistics 



The logistical requirements of an indicator can be costly and time-consuming. These requirements must 

 be evaluated to ensure the practicality of indicator implementation, and to plan for personnel, equipment, 

 training, and other needs. A logistics plan should be prepared that identifies requirements, as appropriate, 

 for field personnel and vehicles, training, travel, sampling instruments, sample transport, analytical 

 equipment, and laboratory facilities and personnel. The length of time required to collect, analyze and 

 report the data should be estimated and compared with the needs of the program. 



Performance Objective 



1. Demonstrate the feasibility of data acquisition with respect to the proposed scale and intensity of 

 monitoring in terms of staffing, training, travel, equipment, laboratory facilities, and data turnaround 

 time.
