San Diego ocean fishing statistics
Data for this study was collected from website sandiegofishreports.com
It includes daily trip reports by San Diego recreational fishing vessels from January 2009 to end of June 2018.
Each report consists of starting date and duration of the trip, boat name, number of anglers and fish count by species.
The amount of data is considerable - 109 boats with 51,422 fishing trips during 9.5 years, with a catch of 89 ocean species
Data preparation and analysis was mostly done through R library dplyr. Charts were generated with R library ggplot2 and library formattable was used for the two tables.
The chart above gives an overview of the fish species being caught on half-day trips. It represents quantity proportions, not quantities.
The spike seen on July 22, for instance, corresponds to more Rockfish and Sculpin caught than Calico Bass. Data for that day is shown on the right.
If updated daily, the chart could help fishermen target the most abundant fish type.
