Fecundity at length for grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>Circles represent data from the current study, and crosses represent data from Love and Johnson (1998; see text). Solid line is the best fit line.</p

Length frequency distributions of grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>A) All data combined across the study regions, B) length frequency distributions for the high productivity subregion, C) length frequency distributions for the low productivity subregion.</p

Parameter table inlineing models, equations and parameter estimates for grass rockfish (<i>Sebastes rastrelliger</i>) in the high productivity, low productivity, and combined subregions of the Santa Barbara Channel, CA, USA.

<p>NA indicates that a single model described the fecundity and length-maturity relationships for all regions.</p

Commercial fishery landings of grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>Box plots show the median (solid line), interquartile range (box), and 95% confisdence intervals (whiskers) of the landed grass rockfish biomass (kg.) over the years 2000–2009 for the high and low productivity subregions, and for data combined across the study regions.</p

Probability of reproductive maturity for grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>A) Probability of maturity at age, B) probability of maturity at length. Solid line represents the maximum likelihood fit to the data. .</p

von Bertalanffy growth curves for grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>Solid line represents the fit to data from the high productivity subregion (circles) and the dashed line represents the fit to data from the low productivity subregion (triangles) Inset depicts 95% confidence intervals around estimates of <i>K</i> and <i>L</i>_∞ (Kimura 1980).</p

Yield per recruit for grass rockfish (<i>Sebastes rastrelliger</i>) in the Santa Barbara Channel, CA, USA.

<p>Contour plots for grass rockfish in the A) high productivity region and B) the low productivity region depict the yield per recruit at any combination of fishing mortality and minimum size limit. Figures B and D depict yield per recruit at the current minimum size limit in the high (B) and low (D) productivity subregions.</p

Map of the study region.

<p>Map of the Santa Barbara Channel, including the mainland coast and four northern Channel Islands (left to right: San Miguel, Santa Rosa, Santa Cruz, and Anacapa), our sampling sites (red dots), and a sea surface temperature profile averaged over a 14 day period centered on 10 June 2010 (satellite data from MODIS Aqua, downloaded from NOAA at: <a href="http://coastwatch.pfel.noaa.gov" target="_blank">http://coastwatch.pfel.noaa.gov</a>). Temperatures indicated in the ribbon legend are °C, and white cells in the map indicate areas for which no data (n/d) were available. In our study, high productivity sites were those sampled at San Miguel and Santa Rosa, whereas low productivity sites were located along Santa Cruz and the mainland coast.</p
