Life History Data Matrix

One the primary objectives of the newly-formed Pacific Shark Research Center (PSRC) at Moss Landing Marine Laboratories (MLML) was the creation of a comprehensive life history data matrix (LHDM) covering the entire body of literature on all chondrichthyans (sharks, rays, and chimaeras) of the eastern North Pacific (ENP), from the eastern Bering Sea to the southern tip of Baja California. The new chondricththyan data matrix covers 22 families and 55 species of sharks, 11 families and 43 species of rays, and 2 families and 4 species of chimaeras. The LHDM was modeled after a previous version, completed in 2001, on the life histories of 124 common nearshore fish species of California for the California Department of Fish and Game, under Pacific States Marine Fisheries Commission support.

The information presented in this LHDM is the result of an exhaustive literature survey of research conducted in the ENP on chondrichthyans occurring in the region. It includes information on taxonomy, geographic range, age and growth, longevity, reproduction, demography, trophic interactions, habitat utilization, genetics, recruitment, mortality, and behavior of these 102 species. Where appropriate, data from studies conducted outside the ENP were included for those species with limited life history information. Information was included from both primary and gray literature sources. The LHDM will be updated annually to include new research results. PSRC scientists and graduate students are now working on research projects to fill data gaps uncovered by this extensive literature search.
