Fattened Up on Fish-Popcicles: How to Rehabilitate a Hawaiian Monk Seal

by Stacie Robinson

Start the day thawing and weighing out fish for the day.
Add vitamins to each seal’s first fish.
8:00am feed the seals, wash the dishes.
Entertain the animals, maybe with a sprinkler or a delicious frozen fish-cicle (but avoid focus on people).
2:00pm feed the seals, wash the dishes. Scrub pen floors. Do a lot of admin.
8:00pm feed the seals, wash the dishes.
Log each seal’s appetite and behavior into the medical records system.
Clean up and get ready for tomorrow.
Repeat… 262 times.

That’s how the dedicated staff at The Marine Mammal Center’s Ke Kai Ola (The Healing Sea) Hawaiian monk seal rehabilitation facility made the dramatic transformation you see in Niho‘ole and other young monk seals in need.

Niho‘ole (a Hawaiian name meaning “toothless,” because he was weaned so prematurely that his teeth hadn’t even grown in yet) was in a sad state with virtually no chance of survival when NOAA field staff picked him up on Laysan Island at the end of the 2016 Assessment and Recovery Camp season last August. Now, we brought Niho‘ole back to Laysan, fat and healthy!

Poor juvenile survival is one of key contributors to population decline in endangered Hawaiian monk seals. Reasons may range from pups weaning prematurely to young animals getting outcompeted for food. But the result is that when young animals fail to thrive, they can’t contribute to the population. So, since 2014, NOAA and its partners at The Marine Mammal Center have been working hard to help struggling juvenile seals through rehabilitation at Ke Kai Ola, in Kailua-Kona on Hawai‘i Island. After rehabilitative care, the young animals are healthy and have the fat reserves to re-enter the wild population with a fighting chance.

One of several figures behind this transformative care at Ke Kai Ola is Deb Wickham, Veterinarian Technician and Operations Manager. Deb joined us on our mission aboard the NOAA Ship Sette to bring 2016’s young patients back home.

We asked Deb, “What are the big differences taking the rehab show from Ke Kai Ola to the road (or water)?” No, it’s not the round-the-clock watches to be sure the seals stay safe and comfortable on the ship’s deck. No, it’s not the amount of seal poo to be hosed down and cleaned up. The biggest difference is the challenge of getting seals to eat fish on the ship! Deb explains, “They want to eat in the water. It’s just more foreign, more difficult to get the animals to eat in a small enclosure with just a small water tub while we’re in transit.” Luckily (and by design), these seals are in great shape and can even stand to miss a meal or two if their appetite is down on the ship. Even so, this well-seasoned rehabber has some tricks up her sleeve–who wouldn’t be enticed by fish-cicles?!

Deb enjoyed her time on the ship and was very happy to get to travel full circle with these seals and see them return home! Her dream is to have more opportunities to rehabilitate more seals and get them back home in a timely manner.

And the work continues–no sooner are last year’s healthy rehabilitated seals dropped off, our field staff have already identified animals in need of help this year. A prematurely-weaned pup and an underweight three-year-old came home with us on the Sette and are now getting settled in at Ke Kai Ola. Deb knows it will be a challenge to get these animals in good shape in time for the return cruise this August. But at Ke Kai Ola, that’s just the sort of challenge they can handle.

Luckily Deb has a soft spot for the older seals, like our three-year-old pup. She says they always seem like the hardest cases coming in, but it’s rewarding to see how much changes as they get healthier. We look forward to seeing the turn around in these two youngsters!

24 days, 900 buckets, 4 seals,…

It is the end of another Hawaiian monk seal field season.  The research cruise to pick up all of our field teams has returned, and our Chief Scientist for the cruise, Stacie Robinson, reflects on the experience.

…580 water jugs, 50 pelican cases, 30 liquid nitrogen dewars, 22 pallet tubs, 6 boats, and plenty of odds and ends.  But, hey, who’s counting?  It takes a lot of gear to make a safe and successful field camp in the most remote islands in the Pacific!  And it takes a lot of help to get it all packed and hauled back to Honolulu at the end of the field season!  Huge thanks to the NOAA ship Sette crew and officers (unsung heroes for sure) for another very successful monk seal camp pick-up cruise!

Hawaiian monk seal assessment and recovery camps have been deployed since the 1980s.  By now, it’s a pretty well-oiled machine (even an inexperienced chief scientist can mostly just keep watch as the machine works – thank goodness!).  And yet, the routine never quite becomes mundane.  Every day on the cruise, the monk seal team seems to be confronted with some new challenge.  And every year, the team finds ways to throw in a few curve balls for the ship (mission changes, emergencies activities, and more), and the vessel crews find ways to keep batting a thousand!

Sometime even routine gear loading from camps has its challenges. For example: Aug 13, stop #1 at Pearl and Hermes Camp: “Hey guys, today we just need to be in three in places at once – pick up marine debris from multiple islands across the Pearl and Hermes atoll, find a seal that needs to be tagged, load up some gear, and get done in time to deploy an acoustic device before making our transit 16 hours to the next site.”  Done!

Some logistics never seem to become routine.  Landing on steep rocky islands like Nihoa and Mokumanamana is always a challenge – just one swell or gust of wind away from missing out on monitoring entire monk seal subpopulations.  This year was a treat – weather cooperated and coxswains expertly navigated – we were able to survey both hard-to-track islands.  Numerous seals and healthy pups greeted our survey teams.

Since the Hawaiian Monk Seal Research Program started translocating monk seals between Northwestern Hawaiian Islands sites, their baaah-ing and pooing were welcomed (or at least tolerated) on deck by the crew and officers.  Then transit with seals got a little longer when The Marine Mammal Center’s Ke Kai Ola monk seal hospital brought the possibility of rehabilitating animals if only our ships could bring them to Kona.  How to top such requests?  This year we stretched our capacity to take on our oldest rehab candidate yet (a 5 year female in emaciated condition).  The Sette crew was helpful in taking on a larger animal, and the three other patients picked up this cruise.  And they even accommodated an after-hours small boat launch to save the patients from one more night on the ship when we arrived in Kona as the sun set.

Back to solid ground and the creature comforts of home, scientists and sailors celebrated briefly and then got to work cleaning up camp gear or prepping for the next cruise.  For a novice chief scientist, it’s a relief that none of the wrenches upset the well-oiled machine.  Field staff all home in one piece, complete dataset to better track the species, and four young seals with a second chance at survival – the end of another field season is a little bit like the start of a new year for Hawaiian monk seal research.

All monk seal work was conducted under NOAA ESA/MMPA permits 16632-01 and/or 18786.

NOAA’s A.R.C. Returns

The NOAA Ship Oscar Elton Sette may appear like an ark on the horizon for field researchers who have spent months on remote islands and atolls of the Northwestern Hawaiian Islands. Biologists dedicate two to six months to studying endangered monk seals as part of the Hawaiian Monk Seal Research Program’s long-running Assessment and Recovery Camps or “ARCs.” The field teams rely on NOAA ships for food, water, equipment and supplies in these isolated conservation regions of the Papahānaumokuākea Marine National Monument. The NOAA ships also complete the story “arc” by transporting seals to rehabilitation and back to their homes in the Northwestern Hawaiian Islands.

During its current voyage, from August 3 through August 26, 2016, the Oscar Elton Sette will pick up researchers and their equipment from five sites—French Frigate Shoals, Laysan Island, Lisianski Island, Pearl and Hermes Reef, and Kure Atoll. Additionally, a small group of researchers will be deployed at Midway Atoll (where there is no season-long camp) to continue monk seal assessment and recovery activities. The scientists will also conduct seal censuses at three other sites: Nihoa Island, Mokumanamana (Necker Island), and Ni‘ihau Island.

ARCs are a long-established cornerstone of the Hawaiian Monk Seal Research Program, providing the foundational data and information for species recovery actions. But as conservation challenges constantly evolve, so does field research. This mission will deploy new unmanned aerial systems (UAS) to investigate remote survey techniques for rugged islands that are difficult to survey such as Nihoa and Mokumanamana. The UAS flights will also map vegetation, locate marine debris, and document the deterioration of man-made infrastructure at French Frigate Shoals. As structures and sea walls collapse, it results in entrapment hazards for the atoll’s wildlife, including monk seals.

After retrieving field researchers and their equipment, the Sette will transport weaned seals from NWHI sites to The Marine Mammal Center’s Ke Kai Ola monk seal hospital in Kona, Hawai‘i Island. Years of data have demonstrated that pups weaning under-weight have little chance of survival. Through the partnership between NOAA monk seal scientists and The Marine Mammal Center’s hospital, struggling pups get a second chance. The seal pups receive a season of rehabilitative care and then are returned to their natal sites as healthy yearlings ready to thrive.

Periodically during the expedition, shipboard personnel will collect oceanographic data on subsurface ocean temperature and conductivity by taking CTD (conductivity, temperature, and depth) measurements. The data will be added to a comprehensive NOAA oceanographic database and used to better understand large-scale phenomena like climate change and the dynamics of local features such as oceanic fronts.

The research mission will also provide support for several partner projects and agencies working in the NWHI. A small team of bird biologists for the American Bird Conservancy and U.S. Fish and Wildlife Service will be deployed at Laysan Island. Additionally, the Sette will pick up NOAA sea turtle biologists who have worked alongside the NOAA seal team at French Frigate Shoals.
