Injury was not consistently associated with adult survival to spawning tributaries but some neg- ative survival effects were detected Pinniped-caused injury rates decreased as annual run sizes
Pinniped - Wikipedia
explained above the majority of pinniped strandings occur when animals are pups or yearlings and the cause of stranding is typically malnutrition disease separation from attending female and human interaction Malnutrition may be caused in some cases if the newly weaned pup is not effectively foraging for food causing starvation
2011 Pinniped-Fishery Interaction Task Force Report release
The study concluded that pinniped-caused injuries were generally not well correlated to survival of adult fish It was noted that this is a relevant piece to understand predation impacts on extinction risk
EVALUATION OF PINNIPED PREDATION ON ADULT SALMONIDS AND OTHER
Analyses of pinniped-salmonid interactions in or near the Columbia River suggest that all life stages of salmonids are at risk of predation by pinnipeds (Brown et al 2017 Chasco et al 2017) and that some salmonid runs are at greater risk of depredation and potential extinction than others (Keefer et
EVALUATION OF PINNIPED PREDATION ON ADULT SALMONIDS AND OTHER
Presence and predation by CSL was first observed in the fall of 2008 and has been noted each fall since Additional salmonids were caught by pinnipeds but escaped and swam away with unknown injuries (3 3 2 3 and 2 6 of total salmonid catch escaped in 2008 2009 and 2010 respectively)

WSAS Committee on Pinniped Predation on Salmonids 3 populations Several participants agreed that the influence of habitat loss on pinniped predation and salmonid mortality warrants further research Indifference to Human Presence Several participants reported that pinnipeds especially those residing in areas where hunting is not
Are pinnipeds threatened by humans?
- Pinnipeds are also threatened by humans indirectly. They are unintentionally caught in fishing nets by commercial fisheries and accidentally swallow fishing hooks. Gillnetting and Seine netting is a significant cause of mortality in seals and other marine mammals.
How do pinnipeds affect the environment?
- Pinnipeds are frequently affected by infectious diseases, biotoxin events, and environmental changes that result in prey shifts, all of which can directly contribute to mass morbidity and mortality.
What can scientists learn about pinnipeds?
- Scientists can learn a great deal about what pinnipeds do at sea, how healthy they are, and where they travel by looking at what they’ve eaten—their prey remnants. This is done without hurting the animals by two methods: lavage and scat analysis.
Should pinnipeds be kept in captivity?
- Some organizations, such as the Humane Society of the United States and World Animal Protection, object to keeping pinnipeds and other marine mammals in captivity. They state that the exhibits could not be large enough to house animals that have evolved to be migratory, and a pool could never replace the size and biodiversity of the ocean.
