The goals of the present study were 1) to determine the developmental stage of Alaska plaice eggs collected from depth-discrete tows conducted in the eastern Bering Sea; 2) to examine the vertical distribution of staged eggs; and 3) to determine whether the CUFES could be a suitable sampler of Alaska plaice eggs in the Bering Sea.
Alaska plaice eggs do occur in near-surface waters, making them accessible to CUFES system, but many eggs also occur below the depths sampled with the CUFES.
Report of a workshop on the use of the continuous underway fish egg sampler (CUFES) for mapping spawning habitats of pelagic fish.
Accuracy and precision of the continuous underway fish egg sampler (CUFES) and bongo nets: a comparison of three species of temperate fish.
Both trawl and CalVET samples were collected during all four surveys and CUFES samples were collected during July surveys only (Figs.
Additional trawls were taken inshore to collect extra samples to determine reproductive parameters in areas of sardine spawning activity identified by sardine egg densities in CUFES samples or the presence of schools as indicated by acoustic signals (Fig.
Because the number of positive CalVET tows was low (four of 54 tows during July 2003 and 3 of 48 tows during July 2004), we chose to use data from CUFES sampling.
(1996): [t.sub.h] =30.65 * exp(-0.145*temp-0.037*12)*[12.sup.1.41]/24, where temp is the average temperature from positive CUFES collections during the July surveys, and equals 16.4[degrees]C and 16.3[degrees]C for 2003 and 2004, respectively.
The continuous underway fish egg sampler (CUFES) (Checkley et al., 1997; van der Lingen et al., 1998; Checkley et al., 1999; Watson et al., 1999) is a new device that provides high-resolution spatial maps of fish eggs by sieving the eggs from water pumped from a fixed depth while a survey ship is underway.
The objective of our study was to evaluate the use of the CUFES in the daily egg production method (DEPM) of estimating the spawning biomass of pelagic fishes (Lasker et al., 1985; Parker, 1985).
We used the following approach to evaluate the use of a CUFES in the estimation of daily egg production.
This survey for Pacific sardine employed a new survey design with the CUFES and the California vertical tow (CalVET, see below) (Smith et al., 1985) (Fig.
