Box plots of (A) proportion of age-1 Gulf menhaden 
(Brevoortia patronus ) in total landings per vessel- 
ton-week (vtw) in the purse-seine fishery, (B) Palmer 
Drought Severity Index (PSDI), and (C) river flow in 
the central region during the 3 dominant climate-re- 
lated hydrological regimes in the Gulf of Mexico: av- 
erage regime, or the AMO cold-NAO negative phase 
in 1964-1970; wet regime, or the cold phase of the 
Atlantic Multidecadal Oscillation (AMO) and the posi- 
tive phase of the North Atlantic Oscillation (NAO) in 
1971-1994; and dry regime, or the AMO warm-NAO 
negative phase in 1995-2010. Horizontal lines for each 
box plot indicate the 5th, 25th, 50th (median), 75th, 
and 95th percentiles. Outliners are shown as dots and 
they are labeled by year.

Figure 6 
Box plots of (A) numbers (millions of fish) of age-1 Gulf 
menhaden (Brevoortia patronus ) per vessel-ton-week 
(vtw) in total landings of the purse-seine fishery in the 
northern Gulf of Mexico and sea levels in the (B) west- 
ern and (C) central regions under decadal climate-re- 
lated hydrological regimes: average regime, or the cold 
phase of the Atlantic Multidecadal Oscillation (AMO) 
and the negative phase of the North Atlantic Oscilla- 
tion (NAO) in 1964-1970, and dry regime, or the AMO 
warm-NAO negative phase in 1995-2010. Horizontal 
lines for each box plot indicate the 5th, 25th, 50th (me- 
dian), 75th, and 95th percentiles. Outliers are shown as 
dots, and they are labeled by year.
