The
Pacific sardine, Sardinops sagax, is the main species caught, representing over 70% of landings, although other species such as northern anchovy (Engraulis mordax), Pacific thread herring (Opisthonema libertate, O.
indicated that
Pacific sardine of the northern stock has an ideal physiological thermal range depending on the acclimation temperature, based on an analysis of tissue and blood samples.
In the case of the U.S., Dan Nosowitz wrote in his article "Regulators Vote To Halt All
Pacific Sardine Fishing" that appeared in the April 17, 2015 issue of Modern Farmer, the ban comes after a "desperately bad season."
8 SOUTHERN CALIFORNIA BIGHT AERIAL SURVEY TO ASSESS
PACIFIC SARDINE DISTRIBUTION AND ABUNDANCE
Reconstruction of the history of
Pacific sardine biomass over the past two millennia from sediments showed that sardines tend to vary over a period of about 60 years (Baumgartner et al., 1992).
They found that if they removed just one measurement from their model--sea surface temperature as recorded at the Scripps pier--it became less accurate at tracking observed
Pacific sardine populations off the California coast over the previous 50 years.
Abstract--During the last century, the population of
Pacific sardine (Sardinops sagax) in the California Current Ecosystem has exhibited large fluctuations in abundance and migration behavior.
This fishery is multispecific and includes eight species, although, the
Pacific sardine (Sardinops sagax) is the dominant species (about 80 % of the total landings) (Nevarez-Martinez et al.
By 2002, Canada's cod industry was not alone in its demise:
Pacific sardine, haddock, Bering wolfish, Atlantic halibut, and yellowtail flounder all were on the international endangered-species list.
A remarkable exception is provided by the
Pacific sardine Sardinops caerulea, for which subfossil deposits of scales have generated estimates of population size over the past two millennia, a time scale seldom accessible to ecologists (Soutar and Isaacs 1974, Baumgartner et al.
