Eels are cool in general. Here’s another cool eel story.

I have this weird recollection of watching horse racing on tv as a kid. The race was at Randwick - not far from where the eels migrate from. It was pissing down with rain and the camera panned to Eels swimming across the track or just outside the track and the announcer explained where they were headed. Haven’t thought about it years. Totally forgot the eels did this.

Eels make crazy journeys

American Eels can live as far inland as Minnesota, but will make a journey all the way to offshore Atlantic Ocean to spawn and die, and then their offspring make the trip back.

RDub3685 t1_isrc41j wrote

Freshwater eels. They're catadromous. Which is the opposite of what salmon do, anadromous. American eels are born in the Sargasso sea in the middle of the Atlantic Ocean and then migrate up rivers and streams to mature. They eventually migrate again to the middle of the ocean to spawn and die.

>When the majestic majority make it to the salt water of the ocean, receptors in their nose trigger a physiological change that puts a butterfly’s life cycle to shame. Their eyes enlarge and undergo pigment transformation to improve their vision in the salt water, their pectoral fins enlarge to rub more salt in Nemo’s wounds, their stomach disintegrates as they have eaten their last duckling and their anus shrivels to keep the salt water at bay.

>The fasting, owl-eyed, anus-less eels then swim along the coast of Australia, up past the northern tip of New Zealand (where their Kiwi brethren join them), and further north to the southern tip of New Caledonia, presumably using the slip stream of P&O cruises the whole 2,020km. Here, the females release millions of eggs, of which an estimated one per cent survive.

Salmon too. Salmon will go back to the exact same area they were born in to spawn, making the journey hundreds of miles. It’s amazing

That is true, but salmon are very high maintenance compared to eels. You won't see salmon wriggling across a wet meadow to get to a river. Or live in a stagnant pool of algae infested sludge. Eels are bad ass.

LurkingMcLurkerface t1_isp0c12 wrote

Pulled a 4 foot eel out of the waste water treatment system in work, it either came in as an egg and survived the many chemical treatments and pumps at the front end of the works to get into the waste water treatment stage, where it survived more chemicals and lived long enough to find food and grow to adult size

Or

A 4 foot eel survived being drawn through a number of high speed pumps with impellers spinning at over 1400rpm at a few different stages and then settled down for a nap in the waste water treatment plant.

Both are massively impressive

We released it back to the river, hopefully its doing much better being out of a water treatment facility!!

29

SlightlyAlmighty t1_ispafww wrote

That's a nice paradox: if it was spawned there, its offsprings will return. Sadly, the cycle will end then, between the blades of the impellers.

If it had passed through the blades unharmed, maybe more will come to spawn there, repeating the cycle and creating more impeller resistant and junk eating eels that would mutate and fight the ninja turtles

Good luck farming eels without it being a raising wild-captured juveniles operation, but you could farm salmon from the egg.

Caterpillar89 t1_ispe05d wrote

Salmon travel thousands upon thousands of miles from where their parents spawn them to feed and grow in the oceans and then return to the same ocean. There are salmon that are born in rivers in California and go all the way up into the polar regions to feed. Some salmon can travel over 2,000 miles per year.

4

Flamin_Yon t1_isphunx wrote

This is completely different in my opinion as the newly hatched eels have literally never been to their destination before and aren't following a river. They just somehow know where to go.

Salmon on the other hand hatch and follow the flow of the river to the ocean, then return to spawn.

PandaMomentum t1_isqzrud wrote

Monarch butterflies do this too -- the migration from Mexico to the US and back takes multiple generations. It's the great grandkids that show up in the same forest in Mexico each year. Genetically encoded somehow.

innovatao t1_isoqnud wrote

So Eels live in remote lake A. They ALL go to sea way over there. They all spawn the next generation. Then ALL the adults die. All of them. The kids then all travel back to the same Remote Lake A (TM)??? Do they leave a brochure to tell them where their ancestral home is? A map? That's so cool but wow.

Almost true, as some eels in the Pacific Ocean breed around New Caledonia :

>The spawning takes place in extremely deep tropical water in an ocean
trench, which can be up to 10 kilometres deep and is found at the edge
of the ocean shelf surrounding New Caledonia. (Source)

They still travel hundreds to thousands of km to breed, but not in the Saragossa Sea.

CynicalBrik t1_ispgvga wrote

To my knowledge eels do not home in on the same specific body of fresh water. They are pretty much like the inverse salmon. Eels home in on one spesific area of the sea and then the offspring goes to some freshwater body that they can get to, disregarding where their parents came from. Salmon on the other hand go to the sea and chill around anywhere where there is food and then return to fresh water to the spesific area where they were born.

E: a word

Not remote lakes though, the interest in this story locally is bc these eels are well known inhabitants of the mini wetlands in major city parks in Sydney like Centennial Park and Victoria Park.

We us to rent boats sometimes as a family thing with my dad, from memory it was at lakes enterence victoria , i remember leaving my fishing line in the water just for fun and as we were in bed going to sleep i heard the line spooling into the water , so i jump up and start reeling it in.

Out of the water comes the head of a giant fucking eel , im trying to think of an everyday object that was about the same diameter, maybe like american fire hydrant or large bread plate , the thing was fucking massive i pulled like 3 feet of it out of the water before the line snapped , all this at night half naked, dad was like im glad you didnt pull that fucking thing into the boat

Anyway that was the end of me swiming there thats for fucking sure

Im not sure if it was one of these but it was this size and this is also lakes enterence

batweenerpopemobile t1_ispklq4 wrote

There were probably just nice little rivers, streams and small tributaries previously. When we pave over areas to build up, we cap all of the streams in pipes and bury them, routing all of the runoff into them. I expect it was something like this.

I have a friend who works on similar programs in the UK. They are rebuilding marshland near Cambridge and building grates/sluices to let eels swim through and back to their spawning points. It's cool stuff!

Edit: Eels and other similar fish often have a mild electrical sense, it's like echolation but zaps instead of yelling. Some can use their zaps like a taser but most are just using it to know where they are: https://dwazoo.com/animal/electric-eel/

They don't swim "across the ocean". New Caledonia is about 750 miles off the coast of Australia. The eels swim maybe 1,200 miles. That's comparable to what salmon do. It's plenty impressive without trying to make it sound like they cross the Pacific.
