The saffron cod (Eleginus gracilis) is a gadid fish distributed from the northern Gulf of Alaska (GOA), around the Pacific Rim into the Sea of Okhotsk, and into the Arctic Ocean abutting the North Pacific Ocean (Cohen et al., 1990; Mecklenburg et al., 2016).
Assignment tests placed all but one saffron cod in the group from which it originated.
Given the Arctic Cods food web significance, a novel spatial analysis was used to investigate climate warming effects on this species and a major competitor, the Saffron Cod
. The analysis suggests likely northerly shifts in the distributions of both species and varying population effects.
To the south, saffron cod, Eleginus gracilis, replaces Arctic cod, and octopus is no longer prevalent.
gorbuscha; walleye pollock, Theragra chalcogramma; saffron cod, Pacific sand lance, Ammodytes hexapterus; and Pacific sandfish, Trichodon trichodon.
Pacific sand lance, and saffron cod (Eleginus gracilis) accounted for 96% of the total seine catch.
Two species that were captured only in September were saffron cod (seine) and rainbow smelt (trawl).
For example, if we estimated 100 individual fish from fish taxon A (e.g., saffron cod, Eleginus gracilis) and 300 fish from all fish taxa in all stomachs sampled from that beluga stock, then the % N of taxon A (saffron cod) for that stock was 100/300 or 33%.
Arctic cod were next in estimated length (mean 14.2 cm, range 8.2-21.2) followed by walleye pollock, Theragra chalcogramma, and saffron cod, which were similar in estimated length at 10.7 cm (range 8.2-12.3) and 10.3 cm (range 7.6-16.3), respectively.
Some of the gadid larvae in our catches may have been saffron cod (Eleginus gracilis).
(2) May include a small percentage of saffron cod (Eleginus gracilis) .
We analyzed abundance indices, as logetransformed catch-per-unit-effort (CPUE), of four marine species (arctic cod, Boreogadus saida; fourhorn sculpin, Myoxocephalus quadricornis; arctic flounder, Pleuronectes glacialis; saffron cod
, Eleginus gracilis); two freshwater species (round whitefish, Prosopium cylindraceum; arctic grayling, Thymallus arcticus); and the anadromous rainbow smelt, Osmerus mordax, to determine whether there were increases in the abundances of marine species and declines in anadromous and freshwater species.
