Yearly catches of snook collected in 183-m haul seines, 21.3-m seines, and 6.1-m otter trawls in the Suwannee River estuary, Florida.
Data (symbols) and the fitted exponential model (line) are shown. Data represent total snook catches of all gear types combined.

Combined monthly catches (1997–2018) of snook collected in the Suwannee River estuary, Florida, with all sampling gear combined.
Monthly mean water temperatures, calculated from all sample sites during the study period whether or not a snook was caught, are represented by the black line.
