Fish egg sac from Puget Sound (Pacific Ocean)?

Hi all...
I was wondering if anyone knew what type of fish egg this was? It was part of a sac, consisting of maybe 40 "packets," so to say, of eggs, all of which were attached to a main thing. The egg containers themselves look like small fish, are oval-ish, and are seethrough, revealing little eggs inside. They float. They were found beached in the sand in puget bay. All help is appreciated. I found a list of fish from puget sound, at

artedi.fish.washington.edu/FishKey/

so it must be an egg of one of those fish (I think), but I have no background in fish at all, so I have no clue what it is. One of the eggs was ripped off by a rock when I put it back in the water, so I filled up a container with sea water and some seaweed and rocks, and put it in there.

Any suggestions? Any ideas? Help please!

you need to supply oxygen and the water needs to be continuously circulated so they will survive but no idea what type of fish
