Map of study area for artificial reef deployment off Maizuru, Kyoto, in 2004. Upper-left 
map shows location of Wakasa Bay (in box) along the Sea of Japan. The arrow in the 
upper-right map represents the location of the research area in Maizuru Bay. Lower 
map shows the research area off the Maizuru Fisheries Research Station (MFRS), 
Kyoto University, with the nine artificial reefs (three typesxthree replicates) deployed 
in a line. Observations were conducted after the visual census of the adjacent habitat 
(transects 1-3). Census lines are expressed by thick dotted lines, and -2 m, -5 m, and 
-10 m isobaths are expressed by thin dotted lines. 
recorded. Fish were considered as associating with an 
AR if they were swimming or dwelling within 1 m of 
the AR (Sherman et ah, 2002), and thus fish in an 
area of about 10 m 2 were counted for each AR. Fish 
standard length (SL) was estimated with the help of a 
scale marked on a clipboard and was recorded. Length 
estimates were occasionally calibrated by capturing 
and measuring fish. These calibrations revealed that 
visual SL estimates were within 10% error of the actual 
measured SL. Water temperature and visibility during 
observations ranged from 10.1° to 28.8°C and from 1 
to 5 m, respectively. Biomass calculation for each AR
