Relationship between catch per unit of effort (CPUE) for juvenile black 
sea bass (Centropristis striata) and average water depth (in meters)

Table t 
Generalized linear model results used to examine the relationship between catch of age-0 black sea bass ( Cen¬ 
tropristis striata) and environmental factors. Average salinity and annual North Atlantic Oscillation (NAO) in¬ 
dex (Akaike information criterion [AIC]=90.07) are the best predictors of abundance of young-of-the-year black 
sea bass. Other factors in the models include temperature, NAO winter, spring, and summer indices, El Nino 
Southern Oscillation (ENSO), ENSO index, spring (ENSO.MAM) and winter (ENSO.DJF) indices, and spawning 
stock biomass (SSB). Catch data used were from a time series collected during 1989-2013 in Maryland coastal 
bays.

2013; however, some years did show strong year class¬ 
es. Miller et al. (2016) found that spring during years 
of 2000, 2002, 2008, and 2012 were strong recruitment 
years for age-1 black sea bass, which is similar to our 
results. The catch of age-0 black sea bass did not cor¬ 
relate with abundance of age-1 black sea bass for the 
following year (t+1), indicating that the catch of age-0 
black sea bass cannot predict abundance of age-1 fish 
of the following year. A similar observation was made 
by Miller et al. (2016) and was attributed to overwin¬ 
ter mortality that determined the strength of the year 
class.
