Length-weight relationships have several applications in fish stock assessments and

ecological studies (e.g., Ricker 1975, Newman et al. 2006). Particularly, they are

important for visual surveys of fish populations where the estimated total lengths are

converted to weights to estimate fish biomass (e.g., Hamilton et al. 2010, Sala et al. 2012).

The available information on length-weight relationships and length-length conversions

for marine fishes in California are mostly limited to commercial catch (RecFIN 2009) or

the occasional ecological survey (Miller et al. 2008), and a recent compilation of these

parameters (Cailliet et al. 2000) demonstrated many species are lacking this basic

information. Fishes used in this study were collected in various large- and small-scale

projects by the Vantuna Research Group, Occidental College and California State

University Northridge from 1984 to 2012. These included state-mandated programs

dedicated to assessing the biological and economic impacts of its stocking efforts

(ORHEP) and localized fisheries surveys (San Diego and Morro Bay) where a variety of

species were caught. Measurements of lengths and weights provide the opportunity to

generate information on morphometric relationships that will be useful to other

researchers. Here we provide standard length (SL) to total length (TL) conversions

(Table 1) for 32 near-shore marine fish species (Class Actinopterygii) and length-weight

equation parameters (Table 2) for 71 near-shore marine fish species (57 from Class

Actinopterygii and 14 from Subclass Elasmobranchii), common to central and southern

California (Miller and Lea 1972).

Fishes were collected by several methods. (White Seabass Gill Net Survey) Collections

using monofilament gill nets were made at 19 stations dispersed throughout the Southern

California Bight from 1995–2005 in shallow (5–14 m) depths at the edge of rocky reefs as

part of the Nearshore Gill Net Sampling Program for White Seabass (Age I-IV). For

detailed methods see Pondella and Allen (2000). (San Diego Bay Fisheries Inventory and

Utilization Surveys) Fish assemblages in San Diego Bay were assessed using a variety of

methods (large seine, small seine, square enclosure, purse seine, beam trawl and otter

trawl) (Allen et al. 2002). The bay is divided into four unique ecoregions that were

sampled in April and July of 2005, 2008 and 2012, and by purse seine and square

enclosure only in June 2009. (Morro Bay Fish Survey) Fish populations were surveyed in

Morro Bay using methods similar to the San Diego Bay Fisheries Inventory and

Utilization Surveys in April, August and November of 2005–2007 and in May of 2008.

(Cryptic reef fish collections from King Harbor, Redondo Beach and Agua Hedionda, San

Diego) Collections of cryptic benthic fishes in King Harbor, Redondo Beach have been

made periodically (1–12 times per year) since 1984 by divers using anesthetic and air lifts

(Stephens et al. 1994). A similar collection was made from Agua Hedionda Lagoon in

2005. (Heat Treat and Impingement Surveys) Samples were also collected during heat

treatments in 2005 at Encina Generating Station, Cabrillo Power Plant, and Huntington

Beach Generating Station. For detailed methods see Pondella et al. (2008). Some white

seabass (Atractoscion nobilis) specimens were also collected opportunistically by hook

and line or spear. Additionally, data for giant sea bass (Stereolepis gigas) collected by

hook and line was included (Michael Domeier, pers. comm.). While fishes caught during

some of these studies were batch weighed by species, all individuals used here were

measured individually: TL and/or SL or disc width (DW) were typically recorded to the

nearest millimeter (mm) or occasionally centimeter (cm) and weight was recorded to the

length characteristics parameters of the relationship

nearest gram (g) either in the field or from frozen specimens that were brought back to

the laboratory.

All statistical analyses were performed using R (R Core Development Team 2012).

Standard length to total length conversion equations were established using linear

regression analyses. Length-length models were fitted to the equation TL 5 a+bSL where

SL is standard length (mm) and TL is total length (mm) (Table 1). Length-weight models

were fitted to the equation W 5 aLb, where W is the wet body weight (g) and L is the total

length (mm) or disc width (mm) (Table 2) by log-transforming both the length and weight

data, performing linear regression analyses. Estimated parameters were then back-

transformed to the original scale for reporting. Obvious outliers were removed prior to

model fitting. While some species had a low sample size (N , 30), we report parameters

here for those where 1) the naturally occurring size range was adequately represented in

the sample, 2) the models fit the data well (Tables 1, 2), and 3) the lack of published

information on the species made the parameter estimates of high value (Froese 2006).

Parameters for some species described here have been previously published (e.g. Miller

et al. 2008, Love 2011). However, there is value in including parameters for all species

that we had sufficient data for where sampling locations differ across studies and/or

larger sample sizes were available, permitting future users of the parameters more options

depending on their intended use.
