(A) Size and (B) age compositions for male and female goldeneye jobfish (Pristipomoides flavipinnis ) sampled in 2012 
and 2016 in the Samoa Archipelago and (C) size and (D) age compositions for goldeneye jobfish sampled from fished

significantly between fished and unfished areas, with fish 
in unfished areas 3.7 years older on average than those in 
fished areas (F 1371 =7.07, P<0.005). Fish from unfished 
areas were older and larger relative to those from fished 
areas. Most notably, age compositions were truncated in 
fished areas relative to unfished areas. The maximum age 
in the fished areas was 10 years compared with the maxi¬ 
mum age of 28 years in the unfished areas. Furthermore, 
30% of the individuals in the unfished areas were older 
than the oldest fish in the fished areas (10 years). 
The size and age of goldflag jobfish ranged from 164 to 
403 mm FL and from 2 to 32 years old (Table 1, Fig. 3). The 
estimated maximum age for males (26 years) was less than 
that for females (32 years), although the maximum sizes 
were similar (males: 403 mm; females: 400 mm). Anal¬ 
ysis conducted with Kolmogorov-Smirnov tests revealed 
that the size and age compositions were significantly dif¬ 
ferent between the sexes (size: .D=0.328, P<0.0001; age: 
0=0.234, P=0.001). Within each sex, the results of the 
Kolmogorov-Smirnov tests indicate significant differences 
between fished and unfished areas in size compositions 
(male: 0=0.594, P<0.0001; female: 0=0.506, P<0.0001) 
and age compositions (male: 0=0.462, P<0.000; female: 
0=0.322, P=0.006). Mean FLs for males and females were 
not significantly different between fished and unfished 
areas (males: F 1 158 =1.08, P=0.37; females: F j 104 =1.58, 
P=0.06). However, mean ages for males and females were 
significantly older in unfished areas by 3.0 years for males 
and by 4.3 years for females (males: F 1158 =3.57, P<0.00; 
females: F 1 104 =6.98, P<0.00). For both sexes, and similar 
to the results for goldeneye jobfish in the Samoa Archi¬ 
pelago, goldflag jobfish in the Mariana Archipelago were 
larger and older in the unfished areas relative to those in 
the fished areas, with a truncated age composition in the 
fished areas. The maximum ages in the fished and unfished 
areas were 18 years and 32 years, respectively. Of the sam¬ 
ples from the unfished areas, 10% were older than the oldest 
fish from the fished areas (18 years). However, the oldest fish 
from the fished areas was sampled from Sarigan, the most 
remote island in the fished areas. The maximum age from 
the primary fishing grounds around Guam was 10 years. 
Growth 
The fit of the EVB model to the age and length data for gold¬ 
eneye jobfish supported the models with factors for sex and 
fishing pressure (Table 2). The difference in AIC c between 
the best-fit model (sex and fishing pressure) and the model 
with the next-best fit (just fishing pressure) was 6.13. 
Females reached a larger than males and, consequently,
