1. Read Boxes 6.3 & 6.4 in Hubert et al. (2012) (the complete chapter is here) and consider the items below.1
    • What is C/f called?
    • How is C/f defined (i.e., what is the equation for C/f)? Define all terms in this definition/equation.
    • Describe the conceptual relationship between C/f and N?
    • What are the assumptions that underlay the conceptual relationship between C/f and N? Identify which of these is the “primary” assumption.
    • What has a large impact on estimates of C/f? Describe two ways in which fisheries biologists attempt to mitigate this impact.
    • Describe three situations that may cause the relationship between N and C/f to be “curved.”
    • Describe “hyperdepletion” and “hyperstability.”
  2. Read Section 7.1 in Hubert & Fabrizio (2007) (the complete chapter is here) and consider the items below.1
    • What is C/f called?
    • How is C/f defined (i.e., what is the equation for C/f)? Define all terms in this definition/equation.
    • Describe how measures of effort may different between types of gears. Include specific examples for common types of gears such as gillnets, fyke nets, seines, and electrofishing.
    • Define “a stock.” Why is this important when considering C/f data?
    • What are four common uses of C/f data?
    • Describe the conceptual relationship between C/f and N?
    • What are the assumptions that underlay the conceptual relationship between C/f and N?
    • Critically assess the assumption of “constant catchability.”
    • Describe “hyperdepletion” and “hyperstability.”
  3. Read the “Problems with cpue data” section in Maunder et al. (2006) and consider the items below.
    • Describe the conceptual relationship between CPUE and N?
    • Describe four things that cause q to change over time in a commercial fishery. [Don’t just list these items, provide a description.]
