| Outline of Annual Research Achievements |
a. Respirometry-acceleration experiments: Established a respirometry system, at considerable unplanned cost, to conduct these experiments on abalone, Haliotis discus hannai at the Atmosphere and Ocean Research Institute (AORI).
b. On a field trip to Otsuchi, including the International Coastal Research Centre (7-11th September 2015) I found out the current state of scallop and abalone farming off the Sanriku Coast after the 2011 Tohoku earthquake and tsunami.
c. I visited the Iwate Fisheries Technology Centre and they provided me with some research data on scallop growth but unfortunately it was inconclusive data on environmental conditions (natural wave action) rather than anthropogenic disturbance. Further, they do not plan to do any research on the possible effects of anthropogenic disturbance on scallop growth. I continue to suggest collaborative research with Iwate Fisheries Technology Centre e.g. the effect of artificial illumination at night on the growth rate of their abalone.
d. I provided feedback on research at weekly laboratory seminars and also at informal meetings.
e. I wrote up my research for publication and reviewed manuscripts for several journals including Physiology & Behaviour and Marine Biology (acknowledged as a ‘named’ reviewer in the Marine Biology publication). I presented a hitherto unreported relationship in any species in my 2016 Royal Society Open Science paper.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
There was a delay in starting the respirometry-acceleration experiments at AORI because no suitable facilities existed when I arrived (e.g. tanks, respirometry chambers and automatic water changers) and the respirometry research room at AORI is not temperature-controlled. Thus, I had to wait until winter to obtain respirometry-acceleration data at low temperatures; my large water coolers could not cool sea water by more than 10°C.
|
| Strategy for Future Research Activity |
a. Complete abalone respirometry-acceleration experiments.
b. Compare my abalone respirometry-acceleration data over a wide range of temperatures with my data for crabs and scallops and any data provided by other members of a laboratory.
c. Collaborate with Iwate Fisheries Technology Centre and other researchers.
d. Plan fieldwork for summer 2016.
e. Write up my research for publication and conference presentations.
