Fish Movement Videos

Click on the Movie Download links below to view a video summarizing the travels that each tagged fish made while tagged. The movies depict the movement of tagged fish (shown as yellow dots on the map) between hydrophones.

Each time the movie updates, it summarizes:

a) which hydrophone heard the fish on the date shown,

b) how many times the hydrophone subsequently heard the fish, and

c) over how may days the hydrophone heard the fish.

Note also that the bottom right portion of the movie frame depicts the moon phase for the date the fish was first heard at the hydrophone.

IMPORTANT NOTE ABOUT THE VIDEOS: The Flash movie files will work best for most browsers. If you do not have a Flash Player installed you can download it online. To view the Media Player videos, you will need to download and install the codec TSCC.exe.

Tagged during Jan 2005 SPAG. Lives on Bloody Bay wall. Only went in Jan 2005, then sat on a vr2 on its home site until 2006 spawning season. Went in both Jan and Feb 2006 to the West end SPAG.  Between the Jan and Feb 2006 spawning periods the fish bounces around on the West end quite a bit, and also visits the east end of the Island. Around the new moon the fish spends about 3 days on the west end SPAG.

Tagged during Jan 2005 SPAG. Lives on Bloody Bay wall. Went to the west end SPAG in both Jan and Feb 2005 and 2006. Like others, this fish migrates to the SPAG a few days after the full moon in Feb 2005.  This fish doesn’t bounce around all that much between Jan and Feb 2006, but does go back and forth up until the new moon, when it heads back to the home site and stays until Feb spawning period.

Tagged during Jan 2005 SPAG. Lives on the southwest end of the Island (~1-2km away from west end SPAG site). Went to the west end SPAG in Jan and Feb of both 2005 and 2006. In between it sat on the VR2 near its home site the whole time. Like others, this fish went to the SPAG AFTER the full moon in Feb 2005. Unlike many of the other fish, this one doesn't explore the island between Jan and Feb 2006 spawning periods, although it does bounce to and from the west end SPAG during this time, up until the new moon when it stays at its home site until the Feb spawning period.

Tagged during Jan 2005 SPAG. Lives on Bloody Bay wall, mostly out of vr2 range during the year. Heard during spawning season in Jan, Feb, and Mar 2005, and went in Jan and Feb of 2006. Lots of bouncing between home site and the SPAG during winter months. This fish (like others) migrated to the Feb 2005 SPAG a few days AFTER the full moon in Feb.

Tagged during Jan 2005 SPAG. Lives on the southeast end, goes to the west end SPAG in Jan and Feb 2005, and Jan, Feb AND MARCH 2006 (I think this is the only tagged fish that goes in March 2006). The fish uses the same route along the south of LC. In Jan 2006 the fish goes to the SPAG site and stays for 17 days, then leaves to bounce all along the south side of the Island, including up to the east end SPAG site.  This fish covers a lot of ground during the 2006 spawning periods.

In Jan 2006 the fish goes to the SPAG site and stays for 13 days, then leaves on the new moon and goes back to the home site.  This fish doesn’t bounce as much as other fish do.

Tagged in August 2005 somewhere on the Western half of the Island. First heard during the Jan 2006 spawning period on the west end SPAG, and then heard consistently over the remainder of the year at the SPAG site, until October 2006 when it is briefly heard by the VR2 on the northwest edge of the island.

Tagged in August 2005 on the east end of the island. First heard while migrating to the west end SPAG site in Jan 2006. Goes to the west end SPAG in both Jan and Feb 2006. Between Jan and Feb spawning periods the fish bounces all along the southern side of the island, but never gets all the way to the east end spawning site.

Tagged during Jan 2005 SPAG. Lives on the southwest end of the island.  Goes to the west end SPAG in both Jan and Feb of 2005 and 2006. In 2006 the fish twice goes to the east end SPAG site and stays there for multiple days. Both spawning moons the fish spends the first few days at the east end before going to the west end SPAG for the remainder of the spawning period. INTERESTING!!!

Tagged during Jan 2005 SPAG. After tagging the fish stays in perpetual motion, bouncing on and off the west end SPAG, never moving more than 2 hydrohpones away (stays on the west end of the island).  Last heard at the west end SPAG site a few months following the Feb 2005 spawning period.

Tagged during Jan 2005 SPAG. Lives on the north-east end, migrates each spawning moon (multiple per season) to the west end on the same route along the south of LC. Between Jan (week moon) and Feb (strong moon) of 2006, the fish swims the migration route multiple times. Perhaps returning to home reef to feed? Or checking out other fish?

Tagged during Jan 2005 SPAG. Goes to the SPAG twice in 2005 and 2006. But, like other fish, it bounces around and returns to the spawning site multiple times between Jan and Feb 2006 spawning periods. Many fish appear to briefly visit the SPAG site (or begin migrations home from the SPAG site) on the new moon between Jan and Feb 2006. HMMMMM.

Tagged during Jan 2005 SPAG. Lives on Bloody Bay wall. Goes in Jan and Feb of both 2005 and 2006. Between the Jan and Feb 2006 the fish bounces back and forth between its home site and the west end SPAG. The one point off of Owen island (south side) is spurious, and represents a code collision.

Tagged during Jan 2005 SPAG. Doesn't appear to have a home site, bounces around the west end hydrophones, then goes away mid-2005. Two spurious points on the end of the data, one from Bloody Bay wall (heard once on one day) and one from the west end SPAG in 2006 (heard once on one day). I removed these points for the movie.

Tagged during Jan 2005 SPAG. Goes to a home site at Bloody Bay wall after the Jan 2005 spawning (when it was tagged) and is heard from for two months at the site before it disappears. Obviously the fish does not return to the spawning site in Feb 2005. One spurious point at the end of the data from the Feb 2006 spawning period (heard once on one day). I removed this point from the movie.

Tagged during Jan 2005 SPAG. Lives north-central (beyond Bloody Bay wall). Goes multiple times per season. In 2006 (just like others) the fish bounces around between spawning moons, and even goes around the west end and ventures all the way up to the east end to check things out before swimming back to the west end in Feb 2006 for the big show. After Feb, goes back to its home reef.

Tagged during Jan 2005 SPAG. Lives on the North east side of the island. Didn't go back to the SPAG in Feb 2005. Went to Jan and Feb 2006. Like other fish, this fish bounced around  between Jan and Feb 2006, and went to the spawning site briefly between the Jan and Feb spawning periods. Most fish that had this behavior ended up going back to their home reef for a period of 4-9 days (just after the new moon) before the full moon in February.

Tagged during Jan 2005 SPAG. Lives on Bloody Bay wall.  Goes Jan and Feb 2005, and Jan and Feb 2006. Like others, this fish bounces around between Jan and Feb 2006, and actually stays on the SPAG site for a few days during the new moon. A few things I thought about while watching this: 1) it seems that in 2005, fish generally went home and stayed home in between spawning periods Jan and Feb. Perhaps this was because there was actually spawning in Jan in 2005, whereas in 2006 Jan didn't have any spawning, so fish are more nervous about missing the big show? 2) In Feb 2006 fish tended to show up shortly AFTER the full moon, but during 2006 fish showed up shortly before the moons in both Jan and Feb. Again, is this related to the fact that spawning happened in Jan 2005? 3) Basically all the fish that are alive in 2006 go in both Jan and Feb, whereas in 2005 several fish only went in Jan. This must be related to the fact that Jan had spawning in 2005.

Tagged during Jan 2005 SPAG. Lives on the east end. Goes to the SPAG in Jan and Feb of both 2005 and 2006. Like others, bounces around between spawning periods in 2006, and doesn’t leave he SPAG entirely until the day of then new moon between Jan and Feb. It sure seems to be that these fish are cueing on the new moon between the spawning periods. Remember to look into this later.

Tagged during Jan 2005 SPAG. Lives up near the North east end. Doesn't go to the Feb 2005 SPAG. Goes in Jan and Feb 2006. Bounces back and forth between its home site and the SPAG, but goes back a few days before the new moon and stays at its home site until just before the full moon in Feb 2006.

Tagged during Jan 2005 SPAG. Lives near the SPAG site, on the north side. Goes to the SPAG in Jan and Feb in 2005 and 2006. Again, I noticed that this fish, like others, went to the SPAG site shortly AFTER the full moon in Feb 2005. Why did they do this? Between the 2005 and 2006 spawning seasons the fish sits on its home site and is heard regularly by the hydrophone. In Oct 2006 the fish begins to bounce around the Western half of the island for almost a month and is last heard on its old home site toward the end of October. Did we witness the it's last ditch efforts to find food (bouncing around) before returning to its home to pass on? Or did it simply relocate away from the hydrophone? Interesting.

Tagged during Jan 2005 SPAG. This fish lives on the south eastern side of the island. In 2005 this fish goes to the spawning aggregation in Jan, Feb, March and April, although the April visit is only 2 days and happens closer to the new moon at the end of April. After this it sits on its home sit until Jan 2006 spawning period. This fish goes to the SPAG in Jan, then after 8 days returns to its home site and then turns right around on the same day and heads back to the SPAG. It subsequently stays for only a day before heading back to the home site prior to the new moon. Many of these fish exhibit this behavior: leaving the SPAG at the tail end of the Jan 2006 spawning period, going all the way back to their home reef and then turning around and going back to the SPAG for a short while. Why?

Tagged during Jan 2005 SPAG. This fish lives on the northeast end. Goes to the SPAG twice in 2005. In Feb 2005, goes to the SPAG around the south site, but returns along the north side afterward. There is one spurious point on bloody bay wall that is probably a code collision. The fish disappears off it home site in the summer of 2005.

Tagged during Jan 2005 SPAG. Stays on the SPAG for7 days after being tagged, then heads east along the northern shelf edge before disappearing around Bloody Bay wall. The fish is heard 4 times during the Jan 2006 SPAG, and not once in the February 2006 SPAG, which is odd if the assumption that these hits during the Jan 2006 SPAG are spurious. On the other hand, there are no hits suggesting migration to or from the SPAG site in Jan 2006. Hard to know how to interpret this, but I believe these hits in Jan 2006 were the result of a particular tag combination that existing during that spawning period which was particularly good for code collisions that yielded 3923. Hmmm.

Tagged in August 2005 on Bloody Bay wall, the fish attends the SPAG in Jan and Feb 2006. Between the spawning periods the fish bounces around a good deal, going about half way up the south side of the island before returning to the west end. Subsequently the fish sets up what appears to be a temporary home site near the SPAG for 20 days prior to attending the Feb SPAG. Afterward the fish returns to its original home site and stays there for the remainder of the year.

Tagged the fish in April 2005 on the south-central side of the island. Attended the aggregation in Jan and Feb 2006. Between the spawning periods the fish is in constant motion, going from the West end SPAG eastward past its home site, and then back west again, around the western end up to bloody bay wall, then back to the SPAG. Lots of motion.

Tagged in August on the eastern end of the island. And it has yet to move since. It was recorded at the hydrophone during days of spawning, so I don’t think it made any kind of movements during spawning season.

Tagged in July on the east end. It isn't heard by vr2s until spawning season. The fish goes in both Jan and Feb 2006, and does the usual weird revisit to the SPAG site during the new moon. In fact, this fish basically covers the entire length of the island several times between Jan and Feb 2006 spawning seasons.

Tagged in April 2005. The day of and the day after tagging the fish swims the length of the island on both sides, and is last heard on Bloody Bay Wall two days after tagging (directly opposite side of island from where the fish was tagged).

Tagged in July on the northeast side of the island. First heard during spawning season. In Jan 2006 the fish first explores the east end aggregation site, spending a few days there before heading west. The remainder of the spawning season involves lots of moving but during the important days the fish is at the SPAG site for spawning.

Tagged at the Jan 2005 SPAG. The fish has a home site near (~2km away) the west end SPAG. Only did the Jan SPAG in 2005, but in 2006 did Jan and Feb SPAGs. This was one of those fish that spent a few days at the west end SPAG site during the new moon. Weird stuff. Lots of bouncing on and off between spawning periods.
