SAMPLING METHODS SUMMARY
[ back to previous window ]     [ close this window ]

Zooplankton samples were collected in May-June 1998-2005 as part of the Basque Country survey to estimate the BIOMass of ANchovy (Engraulis encrasicolus). Consecutive stations are 3 nautical miles (nm) apart located in transects spaced 15 nm apart covering the Bay of Biscay. Samples were collected using vertical hauls of a 150 micrometer (um) PAIROVET net fitted with a flowmeter and lowered to a maximum depth of either 100 meters, or 5 meters above the bottom at shallower stations. The PAIROVET net consists of a paired net with a mouth aperture of 0.05 m2 that is a version of the CalVET net (Smith et al. 1985).
