3).--Larvae were collected from the Gulf of Alaska to the Washington coast using neuston nets, bongo nets, Tucker trawls, MOCNESS
, Methot trawls, and dip nets.
In the laboratory, all larval fish were removed from all neuston samples, samples collected in 2003 with both the l-[m.sup.2] and 4-[m.sup.2] MOCNESS, and samples collected in 2004 from only the 4-[m.sup.2] MOCNESS.
A total of 665 individuals (521 individuals identified to species) were collected in 384 stations (both MOCNESS frame sizes and all depths combined) from the Straits of Florida.
Further, a higher specimen-to-sample ratio was observed in the Straits of Florida (665 individuals in 384 MOCNESS stations)than that from the Gulf of Mexico (544 individuals in 16950 bongo and neuston stations).
Vertical distributions of eggs determined with MOCNESS tows
The hypothesis that vertical patterns in egg abundance vary with depth and developmental stage was evaluated by using data collected from MOCNESS tows.
Collection of all MOCNESS
tows discussed in this paper was made possible through two grants to W.
The vertical distribution of eggs and larvae was examined from samples from four 1-[m.sup.2] MOCNESS
(multiple-opening-closing-net and environmental sensing system) tows.
taken with a 1-m MOCNESS
[multiple opening and closing net and environmental sampling system] [Wiebe et al., 1976]).
To determine if shortbelly rockfish larvae occur deeper in the water column than 140 m, a series of 1-[m.sup.2] multiple-opening-closing-net with environmental sensing system (MOCNESS) tows was conducted aboard the RV David Starr Jordan (cruise DSJ-9203) during the 1992 spawning season.
Examination of the standardized catches from the MOCNESS tows conducted in 1992 revealed that shortbelly rockfish larvae were not caught in depths below the 120-160 m interval (Fig.
