Boreogadus saida

Chirality has shown that at least some POPs are not likely to be biotransformed by some fish species. Some legacy POPs were racemic in fish, such as the toxaphene congener B7-1453 in cod liver oil [214], as well as cis- and ira 5 -chlordane, a-HCH, o,p -DDT, and photodieldrin in fish oils purchased from various countries [215]. Arctic cod Boreogadus saida) also had racemic amounts of a-HCH, cis- and ira 5-chlordane, U82, MC-5, and MC-7 [190, 216], as well as MC-6 [216] and PCBs [192]. Emerald rockcod (Trematomus bernacchii) in the Antarctic also had racemic residues of a-HCH [195]. 

Boreogadus saida), ringed seal (Phoca hispida), and polar bear (Ursus maritimus) (Muir et al. 1988)—and biomagnification factors (BMFs) were calculated. The existence of biomagnification was demonstrated, and a number of other important facts emerged ... 

The existence of an antifreeze-like substance in northern polar fish has been confirmed more recently by Scholander and Maggert (15), Hargens (16), and Raymond et al. (17), who found it in the saffron cod, Eleginus gracilis. An antifreeze substance also has been reported in the winter flounder (Pseudopleuronectes americanus) (18,19,20). Our laboratory recently has found antifreeze glycoproteins in the polar cod (Boreogadus saida) from the Barents Sea north of Russia (10).

The congealing temperature of the blood serum of polar fish of Arctic or Antarctic regions (e. g. Trematomus borchgrevinski, Dissostichus maw-soni, Boreogadus saida) is about — 2 °C and thus is significantly lower than that of other fish (—0.6 to — 0.8 °C). Antifreeze gly-coproteins account for such low values. The amino acid sequence of this class of proteins is characterized by high periodicity ...
