Genetic variability of the highly valuable gadid species, walleye pollock, Theragra chalcogramma (Pallas 1811), from five spatially separated northwestern Bering Sea areas (Ozernoi Bay, Olutorskyi Bay, Koryak shelf, Navarin region, and Anadyr Gulf ) was investigated.

Population Structure and Dynamics of Walleye Pollock, Theragra chalcogramma
1999The population biology of walleye pollock, Theragra chalcogramma, is described including its life history, population dynamics, genetic structure and metapopulation structure. Walleye pollock is an important species in the ecosystems of the subarctic Pacific Ocean, and is one of the world’s largest fisheries.

Poly(hydroxyalkanoate) Biosynthesis from Crude Alaskan Pollock (Theragra chalcogramma) Oil
Journal of Polymers and the Environment, 2008Six strains of Pseudomonas were tested for their abilities to synthesize poly(hydroxyalkanoate) (PHA) polymers from crude Pollock oil, a large volume byproduct of the Alaskan fishing industry. All six strains were found to produce PHA polymers from hydrolyzed Pollock oil with productivities (P; the percent of the cell mass that is polymer) ranging from

Optimum temperature for growth of juvenile walleye pollock Theragra chalcogramma
Journal of Experimental Marine Biology and Ecology, 2007Abstract Food consumption (FC), specific growth rate (SGR), and gross growth efficiency (GGE) were measured for juvenile walleye pollock (initial size 112–153 mm fork length) fed euphausiids at temperatures ( T ) between 2 and 16 °C. FC increased up to 12 °C (7.3% of body weight) and was slightly lower at 16 °C. SGR also increased up to 12 °C (2% d −

Development of the escape response in larval walleye pollock ( Theragra chalcogramma )
Marine Biology, 2001The development of the escape response of walleye pollock (Theragra chalcogramma) larvae from attacks by macrozooplanktonic and small-fish predators was quantified in laboratory experiments. Behavior was recorded using video cameras with silhouette illumination from infrared-emitting diodes and by visual observation. Laboratory-reared larvae of 1, 3, 8,

Analysis of the genetic structure of northwestern Bering Sea walleye pollock, Theragra chalcogramma
Environmental Biology of Fishes, 2004The intraspecific structure of major populations of the walleye pollock Theragra chalcogramma from the northwestern part of the Bering Sea was studied. Specimens from Navarin, Olyutor and Shirshov shoals were sampled in the 2001 spawning season. Preliminary cluster analysis (TREECON) of PCR-RAPD data revealed the existence of cluster with low level of ...

[Temperature decolorization of the rhodopsin of bulls and Theragra chalcogramma fish].
Zhurnal evoliutsionnoi biokhimii i fiziologii, 1977It has been demonstrated that fish rhodopsin is less resistant to thermal treatment and it is more readily bleached as compared to bovine rhodopsin. At 18 degrees C, the stability of both rhodopsins decreased in the following sequence: fragments of the outer segments--digitonin extracts-triton X-100 extracts-cetyltrimethylammonium bromide extracts-At ...
