Map of the study area off windward Oahu, showing the deployment sites 
of 6 receivers with their 400-m radiuses of detection. The gray rectangle 
in the inset map indicates the position of the study area off the island of 
Oahu. Two receivers, the locations of which are indicated by the circles filled 
with diagonal lines, monitored movements of tagged juvenile crimson jobfish 
( Pristipomoides filamentosus ) in the snapper nursery on a terrace outside of 
Kaneohe Bay where tagged cultured and wild crimson jobfish were released 
in 2006 and 2007, respectively. Open circles indicate the sites (numbered 
1-4) where additional receivers were deployed in 2007 to monitor the use 
by the tagged wild fish of rock ledge (sites 1 and 4) and soft bottom (sites 
2 and 4) habitats on the slope adjacent to the nursery. Lines indicate depth 
contours in meters. 
conut Island in Kaneohe Bay. Broodstock juveniles 
were originally captured from the Kaneohe nursery 
and raised through sexual maturity in floating pens. 
Spawned eggs were collected from the broodstock pens 
and transferred to tanks in a fish hatchery facility at 
HIMB. Larvae were raised in tanks for 4 months, then 
transferred to floating pens where rearing continued 
until they were 8 months of age and had grown to 
20-24 cm FL, a considerably faster growth rate than 
those reported for wild fish and based on otolith analy- 
ses (DeMartini et ah, 1994; Andrews et ah, 2012). The 
acoustic tags were surgically implanted, and the fish 
were held in a floating pen for 4 days to verify that 
they continued to swim and feed actively. 
Wild juveniles (17-30 cm FL) were collected from 
the Kaneohe nursery by hook and line, verified as crim- 
son jobfish (Uchida and Uchiyama, 1986), implanted 
with acoustic tags, and observed in a floating holding 
pen for 10 days until ocean conditions permitted trans- 
port of fish to the nursery site for release. Two fish 
died, the first within an hour of surgery and the second 
that evening. All other fish schooled and fed normally 
during days of observation. 
The tags were V9 transmitters (VEMCO; 69 kHz, 
9 by 21 mm), each of which had a unique code, was 
sterilized with alcohol, and inserted into the ventral 
abdominal cavity of a fish through a 1-cm incision 
while that fish was anesthetized in a bath of tricaine 
methanesulfonate (Finque! MS-222, Argent Chemical 
Laboratories, Redmond, WA). Iodine and binding tis- 
sue adhesive were applied to the wound, and it was 
closed with a square knot suture made with a 2.0 sur- 
gical needle. To minimize handling, the lengths of both 
cultured and wild fish were measured in the water and 
the percentage of tag weight to body weight was esti- 
mated by using a published length-weight relationship 
for juvenile crimson jobfish {n= 125) collected from the 
study area (Moffitt and Parrish, 1996). In the sample 
of fish tagged, the tags never exceeded 4% of the body 
weight (Brown et ah, 1999). 
On the day of release, we used a receiver to confirm 
that the tag in each fish was functioning and transmit-
