SNACK TIME FOR SEA LIONS

 

61-21-27October 2021  A late-season run of coho salmon is attracting some enormous predators.  At low tide, Steller’s sea lions leave the sea to follow the salmon into fresh water at the mouth of the shallow river.  Some of the sea lions pick a spot to wait and watch.  Some strike a bear-like pose as they watch for a salmon to swim past and then make a surprisingly quick lunge and grab the salmon.  Others inch upstream with their heads underwater ready to grab any salmon within range of powerful bearlike jaws.  And their appetite is Ridiculous!

PHANTOM OF SOLOMAN GULCH

61-18-4Like the brown bear, Stellar’s sea lions come to Soloman Gulch to feed on the millions of pink salmon arriving here to spawn.  Over the past twenty -five years, I have witnessed an increasing number of Sellar’s sea lions spending the first week of July near the mouth of Soloman Gulch.   This year I counted over one hundred sea lions together at a nearby resting site during low tide.

A stellar’s sea lion bites a pink salmon in half.  This is a common technique used by some of the sea lions.  I overheard some guy telling his wife that they bite them in half so they can swallow the fish in two pieces.  But what actually is happening is a bit different.  Like the bears, the lea lions soon tire of a straight diet of salmon and quickly begin to be more selective.  What they want more than anything are the eggs.  That’s why both bears and sea lions both often drop the males soon often they are caught.  When a sea lion catches an egg-laden female salmon they may bite hard  at the head end of the fish then violently jerk the fish to the side, ripping it in half and keeping the salmon head and guts along with the eggs in its mouth.  The photo above shows the sea lion had the wrong end of the salmon and was left with just a tail.  Visitors often comment on how wasteful the sea lions are but nothing really goes to wast.  Bears, gulls, bald eagles, sea otters, harbor seals get what the sea lions leave behind, not to mention all the other hungry fish and crabs and other marine scavengers.

LIFE CYCLE OF PINK SALMON

465-16-8

Pink salmon show up in estuaries in early July by the millions. Pink salmon are Alaska’ most common salmon species.  They also have the shortest life cycle than other salmon species.  Pinks return to freshwater to spawn when they are two years old and immediately begin to  change from silver to green and dark gray.  And, males form hooked jaws and humped backs.
