1. Read Section 9.1 in Introductory Fisheries Analyses with R and consider the items below.
    • What does a “1” in a capture history data format represent?
    • What does a “0” in a capture history data format represent?
    • How many “0”s and “1”s will there be for an individual fish in data that is in a capture history format?
    • What do you know about a fish that has “011001” as its capture history?
    • If there were five sampling occasions, fish with which capture history formats would be counted to determine the total number of fish that were captured on the third sampling occasion?
