Wild fish movements on the slope 
One or more of the 4 slope receivers was 
visited by 85% of the wild fish. Some fish 
passed them briefly, as they emigrated 
away from the nursery into deeper wa- 
ters, and others chose to linger on the 
slope for a while before moving deeper. All 
the receivers were visited, but more than 
half the tagged fish visited the slope re- 
ceiver closest to the nursery (located at 
site 2 north of the nursery; Fig. 1) (Table 
2). There was no significant difference in 
the number of fish visiting soft bottom 
versus rock ledge habitats (MW: Z=-1.3, 
P=0.21). The number of days the fish lin- 
gered at the slope sites varied widely be- 
cause of their habitat type and distance 
from the nursery; however, a mixed-effects 
model showed that the longest stays were 
at the sites with rock ledges (sites 1 and 
3; Fig. 1) (F=4.99, P=G.012). The range of 
fish lengths (18-30 cm FL) did not signifi- 
cantly differ between substrate types (MW: 
Z=-0.172, P=0.88). Temperatures at the 4 
slope receivers were on average 2°C cooler 
(Table 2) than the temperatures at the 2 
receivers in the nursery. Only at slope site 
3, located to the south of the nursery close to the 
head of a deep canyon, were average temperatures 
nearly 1°C cooler than the average temperatures at 
the locations of other slope receivers (KW: ^2=633, 
P<0.001). The receiver at site 3 recorded 3 of the 4 
fish with the longest stays on the slope (28-61 days). 
The fourth fish had the maximum stay (8 days) near 
the receivers deployed in soft bottom habitats (sites 
2 and 4), after it had spent 23 days at the northern 
rock ledge habitat (site 1).

Figure 5 
The diverse set of presence and absence patterns for 4 individual juvenile crimson 
jobfish ( Pristipomoides filamentosus) . Detections of their tags were binned by peri- 
ods of 6 h, that persisted at the nursery offshore of Kaneohe Bay, windward Oahu, 
for a 15-day period in 2007. The gray bars represent hours of night, and the gray 
line is the bottom temperature in degrees Celsius.
