Pacific Mackerel STAR Panel Meeting Report

Chlorinated hydrocarbons in pelagic forage fishes and squid of the Southern California Bight.

Large quantities of DDT and polychlorinated biphenyls (PCBs) have been historically discharged to the Southern California Bight (SCB). While these contaminants have bioaccumulated in sediment-associated fishes, little data exist on concentrations of these compounds in pelagic forage species that are the likely food source for larger predatory mammals and birds. The goal of the present study was...

Temperature effects on Ca2+ cycling in scombrid cardiomyocytes: a phylogenetic comparison.

Specialisations in excitation-contraction coupling may have played an important role in the evolution of endothermy and high cardiac performance in scombrid fishes. We examined aspects of Ca(2+) handling in cardiomyocytes from Pacific bonito (Sarda chiliensis), Pacific mackerel (Scomber japonicus), yellowfin tuna (Thunnus albacares) and Pacific bluefin tuna (Thunnus orientalis). The whole-cell ...
