I'm a rookie in statistics, but just wrapped up a semester of R analysis for natural resources. I'm working on my grad capstone and hoping I might be able to get some help generating ideas for worthwhile analysis to answer the following questions:
****Changes in Run Timing**** I don't have any effect for this question, but just wanting to show how the timing of the fish run has changed from the start of a project to current times. My data is based off of trapping. I was thinking of determining the peak annually, then doing an ANOVA or Linear Model. Is there a better way of doing this?
****Changes in fork lengths**** I have fork length data for multiple rivers over a 15 year period. I wanted to analyze how hatchery or wild status predicts lengths. Are hatchery fish smaller/longer than wild? I had thought to find the mean fork length for fish annually both by sex and hatchery/wild status, then do ANOVA or Linear Model. Is there a better way of analyzing?
****Changes in Age Structure**** Through field sampling, I have scale analysis results telling me the age structure of each year's spawners. Similar to fork lengths, how has this changed over time, and specifically, as an effect of wild/hatchery status and sex.
Any help is much appreciated! Just looking for some ideas because while I really enjoyed ANOVA/regression analysis, I'm sure there are some much better ideas for these questions.
