Many years ago, I night-fished "off" a finger jetty in Yaquina Bay for Sea Bass. It is a blast, and you can catch of ton of tasty fish, in a very short period of time!
The marine waters are open 24 hours for sea bass, snapper, sea trout, flounder, soles, halibut, surf perch, stripers, hybrid bass, and a few others (listed on pg. 100-101 in 2010 reg book).
Two catches, gotta be careful on slime covered rocks. And gotta be observant of the tide changes. It would NOT be pretty to be swept out to sea.
