Kobe plot

A plot that shows the trajectory of the status of a stock over time, its current status, or both. Stock abundance is on the X-axis and fishing mortality on the Y-axis. These are often shown relative to Spawning Stock Biomass capable of producing MSY (SSBMSY) and fishing mortality (FMSY) capable of producing MSY,  respectively. The Kobe plot is usually divided into four quadrants by using a vertical line at SSB=SSBMSY and a horizontal line at F=FMSY and, hence, can graphically depict whether the stock is overfished and/or subject to overfishing.
