Surveys to target spring ichthyoplankton in the Irish Sea were carried out in
1987, 1988 and 1989 (and linked to an earlier series of Nephrops
norvegicus L. larval surveys between March and June of 1982 and 1985).
Ichthyoplankton samples were collected at each site on a planned survey grid.
The data described here consists of the numbers of fish eggs and larvae (and
also Nephrops larvae) identified from the main net samples collected on
the survey in April/May 1988, along with associated positional and ancillary
data and volumes filtered.
