Abstract:

Productivity linked to upwelling strength is an important environmental factor affecting the production and dynamics of octopus populations. This often takes the form of a negative relationship between octopus abundance and sea-surface temperatures (SST). Enteroctopus dofleini (giant Pacific octopuses) is caught as by-catch in several fisheries, but management for octopuses is data-poor. Visual surveys (in Prince William Sound (PWS) and Puget Sound) showed significant negative correlations of octopus counts with winter SST over the previous 30 months in the waters of eastern Gulf of Alaska, as

Abstract:

In upwelling systems around the world, octopus abundance is forecast by marine productivity linked to upwelling strength, often indicated by sea-surface temperatures. Climate change may disrupt populations of marine animals that are linked to such temperature-dependent events. We analysed the relationship of the abundance of giant Pacific octopuses (Enteroctopus dofleini) to Gulf of Alaska and Washington State water temperatures. Abundance was measured in targeted visual surveys in Prince William Sound, Alaska, over the period 1995–2016 and from REEF.org diver surveys in Washington State from

Abstract:

Simultaneous measurements of blood pressure and blood flow were made in the dorsal aorta of the cephalopod Octopus dofleini Wülker. In resting animals the heart rate varied from 8.5 to 14 beats min−1, while aortic pressure typically ranged from about 2.5 kPa at end diastole to 5.5 kPa at peak systole. Blood flow rate varied with pressure, averaging 0.9 ml s−1, with peak flow rates of 1.4–2.8 ml s−1. A slow asymptotic decline in both pressure and flow during the 2- to 4-s diastolic period indicated that the aorta functions as an elastic reservoir, as previously predicted. Aortic impedance spect

Abstract:

Most marine populations are in decline (Pauly, 2000; Leon, 2003) and reports of stable or increasing stocks are viewed with some scepticism (Myers and Worm, 2003). Compensation for decreasing fish stocks by cephalopod populations has been theorized and reported (O'Dor, 1998; Chotiyaputta et al., 2002). Around Hokkaido Island (northern Japan), catch per unit effort (CPUE) of Enteroctopus dofleini is relatively stable (Hokkaido Fisheries Annual Report, 1986-2001). Decreasing inter-specific competition for food, reduced predation pressure by large fishes and a prevailing temperature regime are po
