We conclude that the CUFES is a useful tool with the DEPM
when it is used adaptively to establish sampling strata for CalVETs.
Damage Part for DEPM
. The stress-strain relations of damaged mechanics are governed by the scalar damage which is expressed as follows [17,18]:
, Dietary Exposure Estimates dietary exposures to Potential Model (EPA); multiple chemicals based on data http://www.epa.gov/ from several national, nerlcwww/depm.html government-sponsored food intake surveys and chemical residue monitoring programs.
Sampling of adults should be representative of a population or enough information on stock structure should be gathered to properly weight the adult data used for DEPM
(Stratoudakis et al., 2006).
Seasonal migration Traditionally, DEPM
surveys of CPS have been performed in the spring, during the peak of the sardine spawning season (Lo et al., 2009).
To improve understanding of the role of dietary intake in total exposure to various chemical species, the Dietary Exposure Potential Model (DEPM
) was developed by Technical Assessment Systems (TAS), Incorporated (11), for the U.S.
For sardine, estimates of spawning-stock biomass (SSB) from surveys with the daily egg production method (DEPM
; Lo et al., 2010) comprise the longest fishery-independent time-series.
In commercially harvested species, this information is useful for estimating spawning stock biomass (using daily egg production methods; DEPM
; Pena et al., 2010), measuring larval mortality (Pepin, 1991), and predicting recruitment (Houde, 2008).
Quantification of population egg production per day is also essential for estimating population size (spawning stock biomass [SSB]) when using the daily egg production method (DEPM
; Parker, 1980; Lasker, 1985).
The z value was the estimate from the daily egg production method (DEPM
) surveys off California in 2003 (0.48 [CV=0.08]) and 2004 (0.25 [CV=0.04]) (Lo et al., 2005) because of the lack of sufficient data to estimate z off the PNW.
