Version 2 adds two additional levels of summarization (tables and second level rows), calculates measures of variation (PSE [CV]) and reports
number of observations (count of fish) by trip or by hour. It can also calculate catch rates using only trips where the species was caught.
Units can be reported in numbers, kilograms, pounds or millimeters.
All combinations of the catch types can be summarized by numbers of fish per trip or per hour.
