- Authors
Kratzer, J. F.; Warren, D. R.
- Abstract
The article presents a study which the required years of data for an accurate estimation of mean annual population abundance and annual variability of salmonid. The study assesses the influence of annual variability on the overall population size and confidence intervals of salmonid from 92 long-term data collection stations. Result shows narrower confidence intervals and rate of change of the intervals for more than 2 to 3 years of data.
