I was looking at Amoskeag Fishways calender of events to see what is coming up. It seems their is a world fish migration day. How do you celebrate that? Do you clean a river? Help game wardens stock migratory species fry? remove a dam?

What would be your favorite migratory fish?

How far do you have to travel to consider it a "migration"? Or is it numbers of fish that have to travel in a group that makes it a real "migration"?

Also, how crucial is the migration to the species survival?  Some make very short migrations (e.g., freshwater gobies with a marine larval stage) but cannot survive without it.  Those that migrate up and down rivers but remain in freshwater the whole time (many suckers) at least have a chance of surviving even if their migration is blocked.

Reading the https://www.worldfishmigrationday.com/website it seems that the day is about ensuring free-flowing rivers so that fish can actually migrate.

 

 

 remove a dam? 

 

So looks like this is the only way to celebrate properly.

My contribution to World Fish Migration Day: an American eel ladder on a tributary of the Cape Fear River at Hope Mills, NC.  It's been running about two weeks now.  Not sure if any eels have climbed it yet, but eels were seen in the area while the dam was being repaired. Photos were taken before the lake was refilled (obviously).  The receiving cage is now half submerged.

The answer to FirstChaos' question above is easy: remove a dam or two, especially in New England where there are plenty of "ghost" dams that were useful in the 1840s but do nothing now except to block off habitat. Amoskeag is an interesting place to see fish on the fishway, I will say that.

Just got word yesterday that the first few eels have ascended "my" eel ladder at Hope Mills Dam on Little Rockfish Creek (7 miles SW of Fayetteville NC).  It works!

21 May 2018:  30 eels ascended Hope Mills Dam eel ladder, the most so far in one day.  Total eels captured so far since start-up is about 60-ish I think.  Assuming the bucket bottom is 10-inch diam, some of those eels are 7" plus.
