Central PugetSound Marine Mammal Stranding Network

The Central Puget Sound Marine Mammal Stranding Network has continued to respond to a higher number of Harbor Porpoise strandings than we have experienced at any time in our past - as of November, we have had 13 dead Harbor porpoise strand in Island and Skagit counties, four in the quarter since our last project report.

We conducted two necropsies in September, one of which was confirmed to be a fisheries interaction. Net markings were detected on the face and rostrum of the porpoise, and the necropsy found no sign of disease or ill health, though when we cut into the skull, hemorrhaging was found at the base of the skull and top vertebrae, likely from the porpoise's struggle when it became entangled in the net. Besides being able to document a fisheries interaction, this rare healthy specimen will enable us to do testing on different tissues and organs to compare to the usual diseased porpoise that we necropsy. We are awaiting results of tests on additional necropsies performed this past month, and have two more porpoise in freezer storage awaiting necropsy by our team.

And speaking of our team - we have had some changes this year, as we say farewell to Matt Klope who has been one of our CPSMMSN’s principle investigators for many many years. Regretfully, Matt has resigned that position to make more time for his family and growing taxidermy business, and will no longer be involved with most of our strandings/necropsies - however will come and help out as his schedule allows when we have whales or large pinnipeds on the beach. 
THANK YOU MATT—for all you have done with CPSMMSN!

To replace Matt on our necropsy and stranding team, we have been very lucky to find Dr. Barry Rickman VMD, PhD, DACVP. Barry is a veterinary pathology (Sound Vet Path) specialist and has recently joined our team. He resides in Edmonds—and has a home pet care and euthanasia business, and is a great part of our necropsy and pathology team — we’re very happy to have him on board. Barry has put together a great poster about our porpoise with B-cell Lymphoma,which was presented at the regional Marine Mammal Stranding workshop, and he and Stephanie Norman are working on publication of a paper on this case.

It is only through the help of YOUR donations that the Central Puget Sound Marine Mammal Stranding Network can continue to keep up with stranding response and investigation in the Salish Sea, and we truly appreciate your support.

Summer is the busy season for our Central Puget Sound Marine Mammal Stranding Network, and this year has been no exception! We have been busy fielding calls about Harbor seals nearly every day, as this is the "pupping" season when Harbor seal pups are born. Mom often leaves her pup on a beach unattended while she goes off in search of food, and this provides the pup a chance to rest and warm up on the beach while mom is gone. Unfortunately, this happens at a time when our beaches are full of humans who flock to our many miles of beaches to rest and warm up, as well.

Many well-intentioned but uninformed citizens want to help what might appear to be an abandoned, helpless little seal pup on the beach, but when humans interfere, the ending is rarely good for the pup. Pups have not yet developed a scare response to humans, but their mothers have. So if people are crowding around a pup on the beach, the mom won't come back for it until they are gone. People often think the pup needs to be fed or have water poured on it, but the best and only thing to do if you see a seal pup on the beach is to LEAVE IT ALONE and leave the area so mom will come back.

Good information can be found in NOAA Fisheries great publication "Sharing the Shore with Harbor Seal Pups" - if you live in Washington State or other coastal states where seals are found, we encourage you to read and share this information. One of the most important functions of our Stranding Network is to educate the public about marine mammals, and what to do if you find a live or dead stranded marine mammal on the beach. We have developed a Rack Card about seal pups that is distributed through our volunteers, at events, and at our Langley Whale Center, and we have several educational displays to help educate the public about seal pups.

The Central Puget Sound Marine Mammal Stranding Network has also been responding to a larger than usual number of Harbor Porpoise this year as well - so far nine have been reported and/or responded to in our stranding region. In recent years the entire region has seen an increase in the number of Harbor porpoise deaths, and researchers are now saying the increase is due to the increase in the population of Harbor porpoise - so that is GOOD news!

Good news or bad, the Central Puget Sound Marine Mammal Stranding Network is here to help the public learn about our marine mammals, and to investigate marine mammal strandings to provide information that helps researchers and agencies understand the health of our ocean ecosystems and their inhabitants. Without your support, we would not exist - our heartfelt thanks goes to each and every one of you who donates to this important Orca Network project!
