Roly poly fish eyes

Warning: If you are squeamish about slimy insides of fish, don’t read this post!

This weekend I went out on a kayak fishing expedition. This involved getting up at 5:30 am (although in an Alaskan summer this was not before dawn), paddling for an hour, and then spending 8 hours fishing before paddling back. Although my companions caught a number of rockfish and even a little halibut, I didn’t catch anything.

Well, that’s not true. I did catch something that felt like the mother of all halibut, or possibly a nuclear submarine, but eventually I cut the line because we all concluded it was actually the bottom. Dangit.

When we got back, the fellow we rented the kayaks from was there with his wife and 5 year old son. We got to chatting, and the son, like any good Alaskan child, wanted to see the fish. So we showed them to him, of course, and had a chat about fish he has caught – three herring this spring, apparently.

Then it turned out that, actually, what he was most interested in was the fish eyes. He was poking at them with his fingers, and he wanted them.

My compatriots began to edge away and become very engrossed in the conversation with his parents, so I took a knife and helped him extract the eyes from a rockfish and a halibut. He stuck his fingers right in there until it was loosened up and then I cut through the nerve cord holding it in. I also cut through a membrane layer that covered the whole eye – fish may not have eyelids, but their eyes are covered and secure, not so ready to pop out as ours are.

One of the rockfish eyeballs we sliced open so he could remove a particular small nodule of something hard inside. I’m not real up on my eyeball anatomy, so I couldn’t say exactly what it was, but it was also round, and he regarded it as the true ball of the eye.

His mother fetched a plastic bag for the eyes, and explained that they already have some salmon eyes at home in the freezer, and these will join them.

We actually did an interview with the dad a few weeks ago, and he told us

I love watching my kid play with salmon. He’s fascinated by salmon – he’ll even pick up the dead ones. Pick them apart and try to see what they’re made of and what’s inside of them, what’s in the gut and what they’ve been eating. You know I didn’t teach him that but he’s just fascinated with the whole thing and the fact that they’re half rotten doesn’t bother him at all.

I’ve been thinking about it for the last day or two. Is a fascination with fish an integral part of being a kid in a fishing community, or does it point to some sort of scientific leaning?

I believe both theories are probably true – given the right circumstances most kids are very interested in how things around them work, and circumstances in Alaska provide a lot of fish as part of the things around you. Earlier this summer I worked an art booth at a kid’s fishing derby. We had a bunch of silicone casts of fish that kids could slather paint on and then slap onto paper to make fish prints. Most of the kids over 4 could identify most of the fish species. I also had a conversation two weeks ago with a ten year old boy about pink salmon returns and fishing tactics. He was more on top of it than me.

I know that my sister and I probably spent a fair amount of time dissecting fish as children. I certainly remember watching my dad gut fish, and we also used to check inside the stomach to see what they’d been eating. In high school, I spent a few summers working in a cannery. We didn’t actually put salmon in cans, but I spent 10-15 hour days with salmon guts, sorting the eggs, or roe, from the other slimy bits. (And yes, I got permeated with salmon, myself. If you ever take such a job, pick one set of clothes to wear to work every day, and throw them out at the end of the season.)

Salmon hearts have little valves on them that look like teeth, human molars, the type that you see on posters about dental hygiene. The intestines make a stringy mass like a mop, or seaweed. And the eggs, glistening inside a membrane sac, are gorgeous. The prettiest are chum salmon eggs, which are globular, orange, opalescent. They are full of fats and nutrients, of course, to feed the next generation of salmon, and maybe it is the oils that makes them so lovely, like bath beads or tiny glass marbles.

I realize it’s a very odd thing to wax nostalgic about, fish eggs, but my point is that I learned to appreciate the internal beauty of the fish, and I didn’t stop checking out their insides when I grew up.

When I was a kayak guide we occasionally found fish. Once I dissected a good sized sculpin with a family who had two boys age 8 and 10 or so. It had two little rock crabs in its stomach, and was definitely the highlight of their day. Another time I had an adult guest who came back down to the dock after the trip to watch me hack open the head of a pacific cod we had found (it was missing its tail and was probably discarded by a seal). We found the tiny brain inside, which resembled nothing more than a loogie, and the ear bones, called otoliths.

All of which is to say that I didn’t mind cutting up fish eyes at all. It was pretty fun. I haven’t paid for renting the kayak yet and I got an email from the little boy’s dad that if I don’t pay, he’s going to send me a bag of frozen fish eyes. I’m going to pay him today, but not because I’m afraid of fish eyes!

Edit/update: here’s a picture of the eyeless fish. Just because!

What’s a weir?

In the first photos I posted from our trip to Redoubt Lake, I included this one of Mama Bear, leading her cubs over one of the fish weirs.

Now, I suppose that not everyone knows what a “weir” is. I didn’t really have much of an idea when I started this job, although I did get excited because I saw a reference to a “vortex weir” which sounds like something totally awesome. I still don’t know what a vortex weir is, but the one you see above is a “picket weir.” Essentially, it is a picket fence in the water.

The back side of the weir is supported by big wooden tripods. The front side is metal poles, or pickets, which are threaded through two or three layers of framing to hold them in place. Since they hold up with bears walking across them, you can see that it’s a pretty sturdy structure.

Weir from the backside. Orange-pink bits below the weir in the foreground are salmon carcasses discarded by the bears.

The advantage of the pickets, since they slide up and down, is that they can follow the contours of the bottom of the stream. The bottom of the pickets are covered with sandbags, which hold them down and cover any gaps, making it “fish-tight.”

Since all the returning salmon want to go upstream, or, at Redoubt Lake, up the falls and into the lake, they get backed up behind the weir. (That’s why the bears are there.) The Forest Service staff who are spending the summer working at the weir pull up the pickets to create gaps and let the fish through, counting every one.

Most of the fish get through with no hassle, but 10% of the fish that go through find themselves inside a fish trap, and become research subjects.

Since the bears are sloshing around in the water by the weir, and the water is always pushing to get through and down the falls, they check the weir to make sure it is still fish-tight.

It turns out to be pretty hard to take a picture of someone snorkeling in which they don’t look like dead body, so you might get a better idea from some of the video taken by Elizabeth, the intern working with me.

We’re talking and making noise so that the bears know where are while we’re sitting on the weir and counting fish. On the right you can see Jon standing on top of a log; he’s looking around the corner at the second weir, and then blowing an airhorn to tell the bears they can’t start fishing over there because we’re still around. In the background noise, first I am translating a Russian folksong which I’ve just finished singing, and then later starting to sing the only other Russian song I know. Not captured on this video is my exciting rendition of Angel from Montgomery.

Restoration work: red alders



This week I spent some more time in the field, this time helping watching some folks put trees, a.k.a. large woody debris, into a stream. This makes for good habitat for baby salmon. Although it involved a lot of tromping around in the rain and a lot of no-see-ums who wanted to chew on me, it was fun because I had the right gear to be waterproof and I got to see what is involved in the restoration process.

All the trees added to the stream were red alders, a quick growing tree that takes advantage of disturbed ground in places where there were logging roads, or river bottoms that large logs were dragged through.

Red alders are tall and have white bark, and if I went by the minimal tree knowledge I had coming into this job with the Forest Service (where I have learned much about salmon, and a little about trees) I would have tried to tell you that they were birch trees.

However, once they cut a few red alders down and dragged them around, scraping off the bark, it became obvious that the inner layer of the bark is the color of a nosebleed, hence the “red” of red alder. And I don’t think you see that in a birch…


I thought it was pretty, so I took a bunch of pictures of it. In fact, I was photographing some scraped bark when they started calling my name, and suggested I leave when everyone else was walking off, so as not to leave me alone in bear country.

For the record, there was a bear spotted, but it ran off the trail before anyone but one guy saw it. I saw the tracks, but they weren’t super big.
