Alewife -- Alosa pseudoharengus, subgenus Pomolobus, Herring family Clupeidea, heading upriver to spawn in late spring.
This story centers around the fish ladder at Damariscotta Mills, ME. Damariscotta derives from Algonquin 'Madamescontee' -- place of many alewives/fish.
Alewives have been used for lobster bait pretty much since there have been lobster pots.
The bottom rung of the fish ladder is one small step for fish, one giant leap for...
cue "The Last One" by W. S. Merwin:
'Well they made up their minds to be everywhere because why not.
Everywhere was theirs because they thought so.
They with two leaves they whom the birds despise.
In the middle of stones they made up their minds.
They started to cut.
Well they cut everything because why not.
Everything was theirs because they thought so.
It fell into its shadows and they took both away.
Some to have some for burning.
Well cutting everything they came to the water.
They came to the end of the day there was one left standing.
They would cut it tomorrow they went away.
The night gathered in the last branches.
The shadow of the night gathered in the shadow on the water.
The night and the shadow put on the same head.
And it said Now.
Well in the morning they cut the last one.
Like the others the last one fell into its shadow.
It fell into its shadow on the water.
They took it away its shadow stayed on the water.
Well they shrugged they started trying to get the shadow away.
They cut right to the ground the shadow stayed whole.
They laid boards on it the shadow came out on top.
They shone lights on it the shadow got blacker and clearer.
They exploded the water the shadow rocked.
They built a huge fire on the roots.
They sent up black smoke between the shadow and the sun.
The new shadow flowed without changing the old one.
They shrugged they went away to get stones.
They came back the shadow was growing.
They started setting up stones it was growing.
They looked the other way it went on growing.
They decided they would make a stone out of it.
They took stones to the water they poured them into the shadow.
They poured them in they poured them in the stones vanished.
They shadow was not filled it went on growing.
That was one day.
The next day was just the same it went on growing.
They did all the same things it was just the same.
They decided to take its water from under it.
They took away water they took it away the water went down.
The shadow stayed where it was before.
It went on growing it grew into the land.
They started to scrape the shadow with machines.
When it touched the machines it stayed on them.
They started to beat the shadow with sticks.
Where it touched the sticks it stayed on them.
They started to beat the shadow with hands.
Where it touched the hands it stayed on them.
That was another day.
Well the next day they started about the same it went on growing.
They pushed lights into the shadow.
Where the shadow got onto them they went out.
They began to stomp on the edge it got their feet.
And when it got their feet they fell down.
It got into eyes the eyes went blind.
The ones that fell down it grew over and they vanished.
The ones that went blind and walked into it vanished.
The ones that could see and stood still
It swallowed their shadows.
Then it swallowed them too and they vanished.
Well the others ran.
The ones that were left went away to live if it would let them.
They went as far as they could.
They lucky ones with their shadows.' ~ "The Last One" by William Stanley Merwin
