[Featured]: Fiji Expedition 2022!

Bula Bula TONMO Team!

Our Save the Nautilus team is finally getting back into the field in July 2022 to continue our nautilus conservation work!

Stay tuned for updates...

Awesome! Are you leveraging the same methods and tech as you've done in years past, or is there anything new this time around? (any new sensory equipment, upgraded cameras, any AI, etc?)

Yep, same methods but refined with more partners and more sites... Funding has been pretty limited for us the last few years so we are doing all this on a tight, TIGHT, budget.

Not even sure how AI could help us, but that would be cool! I am sure there is a way to utilize it for video analyses after the fact, but not my expertise...

Bula from Fiji!

First few days have had their ups and downs for various reasons... Save the Nautilus team here in Fiji is myself and Whitney Heuring (Phoenix Zoo). Dr. Peter Ward (University of Washington) will be here on the 18th of July.

Day 1
15 July 2022: Arrived in Fiji early on July 15th. Drove to Lami Fisheries Office to meet with colleagues (Tarisi, Diana, Kanisi, and Moape) there to finalize the surveys. Headed to Department of Environment next to sort out our CITES permit. Then, checked into hotel in Suva with a unique view of mangroves, mangroves, mangroves, and some ocean, šŸ˜„. Back to Lami to meet more fisheries folks and head to hardware stores to get gear. Dropped gear off and back to hotel for dinner and rest. Dinner was lamb korma and pretty good! And of course, a couple Fiji Bitter beers!!! šŸ»

Day 2
16 July 2022: Up around 6am to sort gear and be in Lami by 8am to replace chicken wire on traps and prepare them for catching nautiluses. Diana, Kanisi, and Sero helped with the trap making., making it go much quicker. Had to make a run to the hardware store for some additional wire, but traps ready by about 1pm. A truck was not available to get traps to dock until 430pm so headed back to hotel. Then, truck was ready so back to Lami. Loaded traps around 345pm and out to sea by 430pm. Dropped two traps to similar spots aa previous surveys. Said good night to the traps and back to the dock. Next to the dock was a nice hotel, perfect location, but it now looks like a ruin and is being completely remodeled. Traps will be retrieved Monday because there is no work on Sunday. Grabbed some dinner which was okay lamb rogan josh and headed to bed.


Day 3
17 July 2022: No work today and rain, rain, and rain. Rain let up around 1pm so headed out to do something... went to the Colo-I-Suva Forest Park. The last time we were here it was closed by the time we got there. This time it was open and pretty cool! It was pretty unique and felt like we were walking in Jurassic Park!!! Started raining again and markets closed so back to hotel to rest. Then dinner. Then bed.

Day 4
18 July 2019: Today was trap pulling day!!! When nautilus fishing, or fishing in general, one of the main things is to just get your gear back. Everything after that is icing on the cake, with maybe some sprinkles and a nice cherry on top. We arrived at the dock at around 715am to meet our fishery colleagues to head out to retrieve our traps and were greeted by a great rainbow at the dock! Maybe it will be good luck!

Out at sea, we started the long process of pulling up each trap from about 250 meters... almost there, almost there, almost there... THERE! NAUTILUSES! 8 nautiluses in the first two traps!



As we were measuring and sexing nautiluses, a friendly little sea turtle popped its head up to check out what we were up to before taking a breath and heading back down! It is that green thing in the water in front of the boat...

After that, we reset the traps with more raw chicken and headed in. Dr. Peter Ward was due to arrive in the evening so we met up with him to plan out the next phase of the work.

Day 5
19 July 2022: Traps are going to stay in water another day. This day was spent preparing final logistics for the next big goal of the trip which is... a surprise!
Days 6-13
20 - 27 July 2022: ... the surprise was TRACKING nautiluses in Fiji for the first time! And when tracking starts, it is a grind because we don't just start tracking only, we continue doing everything else - nautilus surveys with traps, shrimp and crab surveys, planning, photography - and my updates always seem to fall off the list at this point. So, to sum up the last week of the expedition...

To track nautiluses, you first have to catch some nautiluses using our normal, meter cubed steel framed traps. Deploying them is the easy part. Retrieving them from 300 meters is the hard part. We have some good "tricks" to getting the trap up and keeping the nautiluses safe, but towards the end, it is just muscle power to pull it up and get it on the boat. All the while, HOPING that there is at least one nautilus in there to learn from and to place a transmitter on. Transmitters are attached to a positively buoyant "saddle" so that when it goes on the nautilus shell, it is neutrally buoyant and does not significantly impact their ability to regulate their own buoyancy.

We went out to retrieve our two traps, just as usual. They aren't too far outside of Suva Harbour and pretty easy for us to see with our GPS points. We passed by our first trap and didn't see it at first, but not too big of a deal, and went to the second trap first since it was further away. Pulled up the trap, after 45 minutes, and.... ONE nautilus. Bummer. But, one more than we had. We also pulled up some crab and shrimp. Placed everything in chilled seawater on the boat and headed to find the other trap. For some reason, a large flag was added to this trap's buoy, to make it easier for us to see in the big waves and swells. We searched and searched and searched, but nothing. Had to make the call to go back to the dock, process the organisms we caught, and attach one transmitter to the nautilus. We would look for the trap when we came back out. Transmitter attached and nautilus moving around well!

The nautilus was dived down, photographed, and released at about 15-20m away from the reef wall. As it was being released, we monitored its descent which was normal, reaching the bottom (which we know using a depth sounder). Now, we just wait and follow the nautilus wherever it goes making notes of its GPS coordinates from the boat, its depth, and the temperature over time. It is exciting at the beginning but hours later, on a small, open-top boat, this is when you have to push forward to not lose focus and become complacent. For me, I like tracking. I like being at sea. I like the stillness and the time to think and just be inundated in this type of science. We did not reset any traps today.

Over the next several days, we started trapping again and continued the tracking studies. The weather was pretty good for the most part. Some light rain every now and then until... our good weather luck ran out and we got hit with some cold, tropical rain. My "rain jacket" didn't really repel much so I was soaked but the important thing was keeping some of our equipment out of the rain, which we did! Through it all, we were able to catch several more nautiluses, attach two more transmitters to two nautiluses, track them, and discover some new things about the nautiluses of Fiji! Along the way, we were invited to a Fijian lovo lunch with the Fijian Water Police - Taro leaves with corned beef and coconut milk, kasava, pork, and chicken. Later, the Fijian Water Police really saved us because our boat was working great so it was not safe to be out at night in it. The bad thing is that the sunset is crucial for testing several hypotheses about nautilus migration. Well, the Fijian Water Police offered to take us out on one of their boats on one evening! How cool!

And then just like that, the expedition was over. If everything went perfectly to plan (how can it ever), we maybe would have come away with more data, but we left with a TON more data than we came with and more importantly maybe, we came away with some stronger partnerships and collaboration opportunities to not only continue this work each year when we are there, but continue it even when we are not there on the ground. Happy last sunrise in Fiji and SAVE THE NAUTILUS!
