– Conditions never seen before by scientists in Pacific seals and walrus — Thyroid cysts, lesions of reproductive system, retained placenta — Hunters concerned — Oceanographers to discuss radiation from Fukushima on Alaska radio tomorrow (ENENews, Jan 27, 2014):
Alaska Marine Science Symposium (pdf), Jan. 20-24, 2014: Incidental Gross Necropsy Findings In Subsistence Harvested Ice Seals And Pacific Walrus […] Ice seals (ringed, bearded, spotted seals) and Pacific walrus are very important subsistence species for Arctic coastal communities. As part of the North Slope Borough (NSB) ongoing Marine Mammal Health Research program, the department of wildlife management conducts necropsies and baseline tissue sampling on subsistence harvested marine mammals. We present some results from our 2011-2013 general ice seal [ringed, bearded, and spotted] and Pacific walrus subsistence harvest monitoring and sampling efforts due to hunter concern NOTE: Case reports (type 1 alopecia/delayed molt; type II ulcerative dermatitis, delayed molt etc.) from the ongoing 2011 Northern Pinniped unusual mortality event disease investigation were not included and will be reported elsewhere. Results: Incidental gross findings among the three species included: lesions of the reproductive system (adnexal cysts, uterine and penile melanosis, cliteromegaly, cryptorchism, retained placenta), endocrine system (thyroid cysts, adrenal nodules), musculoskeletal system (synovial cyst), integumentary system (panniculitis, epidermal molt (aka dreadlocks), skin sloughing) and digestive system (microdontia; chronic interstitial pancreatitis, hepatic cyst; cholestatic jaundice; geophagia). Helminths were commonly observed in the gastrointestinal system of ice seals […] A variety of the observed pathological conditions (reproductive and endocrine lesions) are reported for the first time in Arctic Pinnipeds […]
