A trawl survey was carried out between 27th Feb - 31st Mar 1998 in the Celtic Sea. As additional aim of this survey fish eggs and larvae were collected in order to provide information on the timing of first spawning of mackerel and horse mackerel as part of the trienniel mackerel and horse mackerel survey. 8 plankton samples were taken using a 1.0m ring net. This data consists of the numbers of fish eggs and larvae identified, along with associated positional data and volumes filtered.
