1. Read Chapter 8 in Introductory Fisheries Analyses with R and these notes and consider the items below.
    • What are the three most common condition indices?
    • What is the formula for Fulton’s condition factor?
    • What fundamental assumption about fish “growth” does Fulton’s condition factor make? Why does this make this metric largely useless?
    • What is the formula for the relative condition factor of LeCren?
    • What is the primary limitation for using the relative condition factor?
    • What is the formula for a relative weight?
    • What possible relationship with condition should be checked for before computing an overall measure of condition for a stock of fish?
    • What R function is used to find the coefficients of the standard weight equation for a given fish species? What are the arguments to this function?
    • What statistical test can be used to compare mean relative weights among Gabelhouse length categories?
  2. Read Pope and Kruse (2007) Sections 10.1, 10.3, 10.6, & 10.7 (the complete chapter is here) and consider the items below.
    • What is “condition” a measure of?
    • Condition indices must control for what confounding effect? Put this into your own words.
    • Why is measuring fish condition important to a fisheries scientist?
    • What are the three most common condition indices?
    • What is the formula for Fulton’s condition factor?
    • What fundamental assumption about fish “growth” does Fulton’s condition factor make? Why does this make this metric largely useless?
    • What is the formula for the relative condition factor of LeCren?
    • What is the primary limitation for using the relative condition factor?
    • What is the formula for a relative weight?
    • What value of Wr represents fish in “good condition”?
    • What abiotic and biotic factors have been found to be related to fish condition?
