“…This suggests that hepatopancreas color is related to nutritional status. During starvation or periods of nutritional stress the water concentration of the hepatopancreas increases (Dall, 1974;Trcndall and Prescott, 1989). During nutritional stress hepatopancreas C concentration decreases while N concentration increases (Trendall and Prescott, 1989).…”

“…Temperature also effected changes in Hc function, although this has received less (experimental) attention than either hypoxia or salinity (Rutledge 1981, Mangum 1997). In addition, the effect of food availability on [Hc] has been investigated (Uglow 1969, Djangmah 1970, Dall 1974, Hagerman 1983. Mostly the changes elicited by temperature, hypoxia and food availability have been studied over a timescale of many days and in some cases weeks and months.…”

Changes in environmental factors (PO 2 , temperature, salinity and food availability) influence the concentration of the respiratory pigment haemocyanin ([Hc]) present in many crustaceans. We investigated the possibility that [Hc] and HcO 2 affinity altered during the diel vertical migration (DVM) of Nordic krill Meganyctiphanes norvegica in the Gullmarsfjord, Sweden. The [Hc] decreased with increasing depth, for individuals both trawled and caged at different depths. Laboratory experiments indicated that this pattern could not be explained by differences in PO 2 , temperature or salinity. Alternatively, starvation had a significant effect on [Hc] over the course of a few h (≤10), i.e. a much shorter time scale than found for other crustacean species. Starved individuals showed a dramatic decrease in [Hc] compared with fed individuals. This decrease was exacerbated by an increase in temperature. We suggest that when M. norvegica migrates into deep water during the day, for whatever reason (predator avoidance or reduced prey abundance, or reduced ability to locate and capture prey), they cannot secure enough energy to meet routine metabolic demands; they therefore break down Hc and use it as an energy source. We conclude that there is likely to be a trade-off between the respiratory function of Hc and its importance in nutrition when krill migrate into deeper, nutritionally poorer waters during their DVM.

“…It has long been noted that [Hc] is related to the nutritional state of crustaceans under natural conditions (Dall, 1974; and references therein), leading some researches to suggest that, in times of plenty, Hc serves not only as an O 2 carrier but also as a storage protein. Terwilliger (1998) noted, "This may occur, although storing ex-…”

“…However, it is probable that some of these effects were a result not of reduction in the absolute amount of protein but of dilution of the protein. Dall (1974) showed that blood protein concentration in the longlegged spiny lobster (Panulirus longipes) decreased with starvation within 4 weeks, but this decrease was actually due to the increase in blood volume as solid tissues were metabolized. Djangmah (1970) observed that blood protein decreased from 7.9 g L -1 to 2.55 g L -1 and that there was a progressive accumulation of copper in the hepatopancreas of the common shrimp (Crangon crangon) after 23 days of starvation.…”

Abstract-The effects of commercial fi shing with crab pots on the physical condition of the snow crab (Chionoecetes opilio) and southern Tanner crab (C. bairdi) were investigated in the Bering Sea and in Russian waters of the Sea of Okhotsk. In crabs that were subjected to pot hauling, the presence of gas embolism and the deformation of gill lamellae were found in histopathological investigations. Crab vitality, which was characterized subjectively through observation of behavioral responses, depended on not only the number of pot hauls but also the time between hauls. Immediately after repeated pot hauls at short time intervals (≤3 days), we observed a rapid decline in vitality of crabs. When hauling intervals were increased to >3 days, the condition of crabs did not significantly change. After repeated pot hauls, concentration of the respiratory pigment hemocyanin ([Hc]) was often lower in the hemolymph of crabs than in the hemolymph of freshly caught animals. Our research indicated that changes in [Hc] in crabs after repeated pot hauls were caused by the effects of decompression and not by starvation of crabs in pots or exposure of crabs to air. We suggest that the decrease in [Hc]
