Half a century ago I grew up on Kailua Beach, in Hawaii. It was an idyllic time and place back then. Like many locals my cousins, brothers, uncles, friends, and I used to go spear fishing several times a week for fish, octopus, and so on. Such fun, and nothing like a free dinner! If we caught too much, I'd freeze it. If we didn't catch anything, well, then dinner would be something else. But we almost always caught enough for dinner, and often considerably more than that. We'd cook it over a fire on the beach, or take it home.
And then several times a year all the neighbors would get together and we'd get out the nets and have a hukilau and maybe then a luau after cooking in an imu, since that was usually a lot more fish.
This was more than half a century ago and times have changed, so I don't even know if spearfishing is still allowed. But it sure was fun and seafood fresh out of the ocean is such a treat. We seldom bought seafood at the grocery store, and I don't remember the prices although I do remember that it was always fresh too. I never noticed any that was frozen and re-thawed at that time.
I'd tell you about stringing leis out on our lanai afterwards to wear to school the next day, but that might be overdoing the Hawaiiana aspects of this post!
