ID Distribution of Clupeids from CPR samples for period 4 (years 1978 to 1984) - Kriging
Abstract Fish larvae were collected by the continuous plankton recorder (CPR, operated by SAHFOS) all year long between 1951 and 2005 along transects in the Celtic Sea and English Channel. The CPR is towed by ships of opportunity at speeds of 15 to 20 knots, at an approximate depth of 10 m. Water enters the recorder through an aperture of 1.27 cm2, and is filtered through a continuously moving band of silk with an average mesh size of 270 μm.

Lineage In all, over 50 taxonomic groups of ichthyoplankton were identified, but we focused on the 6 most abundant groups of fish larvae, clupeids (Clupeidae), Atlantic mackerel (Scomber scombrus), rocklings, horse mackerel (Trachurus trachurus), whiting (Merlangius merlangus), and gadoids (Gadidae). These were the only taxonomic groups for which we had enough positive samplings points in order to produces maps of distribution.

The data are aggregated by 7 years periods (1: 1957 to 1963, 2: 1964 to
