Classification of Ovarian Stages of Walleye Pollock (Theragra chalcogramma)
Walleye pollock, Theragra chalcogramma, is the most commercially important species in the eastern Bering Sea. Estimates of maturity are critical for setting an appropriate harvest rate for pollock spawning biomass, and correct classification of ovaries into a maturity condition is necessary for accurate estimation of maturity. Data on length, weight, and ovary weight and condition were collecte...
متن کاملClimate change causing phase transitions of walleye pollock (Theragra chalcogramma) recruitment dynamics.
In 1976 the North Pacific climate shifted, resulting in an average increase of the water temperature. In the Gulf of Alaska the climate shift was followed (i.e. early 1980s) by a gradual but dramatic increase in the abundance of groundfish species that typically prey on pre-recruitment stages of walleye pollock. In the present study we used a previously parameterized model to investigate the ef...
متن کاملAcclimation potential of Arctic cod (Boreogadus saida) from the rapidly warming Arctic Ocean.
As a consequence of the growing concern about warming of the Arctic Ocean, this study quantified the thermal acclimation responses of Boreogadus saida, a key Arctic food web fish. Physiological rates for cardio-respiratory functions as well as critical maximum temperature (Tc,max) for loss of equilibrium (LOE) were measured. The transition temperatures for these events (LOE, the rate of oxygen ...
متن کاملCharacterization of protein fractions from immature Alaska walleye pollock (Theragra chalcogramma) roe.
There are good markets for mature pollock roe; however, immature pollock roe is underutilized. The physical and nutritional properties of immature pollock roe (IPR) have not been reported, which limits its potential use as a food ingredient. The objective of this study was to evaluate the physical and nutritional properties of immature pollock roe and soluble and insoluble protein powders made ...
متن کاملComparing the modelled and measured target-strength variability of walleye pollock, Theragra chalcogramma
Many biological and physical factors potentially affect target strength. While these sources have been identified, few studies have compared the relative effects of individual factors. Modelled and measured target strengths in non-dimensional metrics were used to compare and rank the effects of fish length, tilt, depth, and acoustic frequency on backscatter intensity. Ex situ measurements of ta...
