Starting date, size range, and number of fish recovered in cages in the outer, central, and inner reaches of Punta Banda Estuary. 
Cages were recovered after 14 or 28 days; each row indicates a single cage (n = 6 juveniles). Asterisks indicate locations in which 
cages were not recovered. No data (n. d.); cages were not seeded because of low capture rates.

distributions of California halibut <200 mm SL caught 
in different sections of the estuary were compared by 
using the nonparametric Kruskall-Wallis H test. 
The relationship between density of fish <200 mm SL, 
environmental conditions, section of the estuary and 
sampling time was evaluated by using a general lin- 
ear model (GLM). Densities were log(x+l) transformed 
to achieve normality. Temperature, salinity, DO, and 
depth were were included as continuous predictor vari- 
ables. Section of the estuary and sampling time were 
included as categorical variables. Data corresponding to 
the beginning and end of each caging experiment were 
pooled for analysis and considered as a single point in 
time; the data from August 2005 were entered as a 
separate time point. Because there were significant cor- 
relations between salinity and tempreature (r= 0.487) 
and salinity and DO (r=-0.633), the model was run to 
include an interaction term for these variables. Model
