Auditory Characteristics of Walleye Pollock Theragra chalcogramma (Pallas).
The auditory threshold levels of walleye pollock Theragra chalcogramma (Pallas) were measured in order to determine the optimum conditions for marine ranching utilizing underwater sound. The auditory characteristics of walleye pollock were determined by heart beat conditioning using 8 frequencies of pure tone stimuli from 60 to 1,000Hz coupled with an ...

Basis for calculating technological parameters of preparation of minced salted fish products of intermediate moisture with specified physical and chemical characteristics [PDF]
The dependence of water activity on basic physical and chemical characteristics of salted fish products with intermediate moisture has been defined. During the research the product quality has been assessed by the organoleptic method; determination of ...

Foraging responses of black-legged kittiwakes to prolonged food-shortages around colonies on the Bering Sea shelf. [PDF]
We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts in habitat use with direct implications for population trends.

On the Digestive Ferments of Theragra chalcogramma (Pallas)
The fish can digest food in winter, even though the temperature of its body is nearly as low as that of the environment during that season, the difference between the two being less than 1°C. It may be expected, therefore, that the digestive ferments of the fish are more active at lower temperatures than is the case with those of warm-blooded animals ...

ABSTRACT This study aimed to quantify the cannibal‐prey size relationship using morphometric regression models and to establish an effective size‐grading strategy to prevent cannibalism. A total of 15,000 juveniles at 73 days post‐hatching (DPH) were reared in a circular tank (approximately 12 tons) operated under a flow‐through seawater system at 26.0
