One fish a day thread

[shresearchdude]

Here will be one photo of a fish or research each day. I'll try to add a story about what/where/when. Feel free to ask or post your own stories. Resizing will be a pain in the ass...

1) 10-13 pound Bluefish from a study many years ago from our main research aquarium. This one was an attempt at getting better recreational fishing mortality data on hook/line bluefish. The study worked out well although I thought we could make some improvements. Although the photo is from another study years later,it shows how we get big fish back to our lab at SH. The fish in the tanks mounted on the deck of our 48ft boat are alive-they are just suffering from the bends.
I'll try to post the link related to what was published. Some of the links to research publications might get tricky to access-I take it all for granted...I'll try to post several links-

Very cool. Thanks!

Thanks, looking forward to it. Something to read on a cold winter day and perhaps even learn a little?

Cool stuff John, thanks for doing this. Last time I saw that oblong NOAA tank it did not have bluefish, they look content there !

Goosefish aka Monkfish some pics from bottom trawl cruise and some from our lab. We conducted a gastric evacuation study on them last year. It was based on some info that we really thought could be updated. There was a paper published that predicted that since goosefish were in such high numbers that they were at the time the top predator up further in the northeast. Problem is that the data on predation was built on old data that may not have been as accurate as it could be. So we did the study to determine how quickly there were digesting herring. Considering the teeth and how to handle them was interesting. I only had a few fish snap at me...meaning they sorta jumped out at what I was feeding them-with the longest forceps I could find(12").
Not published yet....they are fascinating fish to watch-as they watch what I was doing while feeding them.
Oh and although they eat fish whole-the fisherman who we got them from remembers pulling a 25-35" striper from the stomach of one-it takes a week for the to digest what they have eaten!

having issues downloading other pics....

Atlantic saury. These commonly get trawled up with herring/mackerel. It's a strange looking fish that eat plankton so the "beak" is a bit odd. They get to about 20"

Great Thread I am enjoying and learning. Thanks

Thanks for starting this thread! I've always been fascinated by the fish and other creatures that live in our oceans. I actually considered becoming a marine biologist back in high school. Keep the post coming, I'll definitely be checking back in!

though not a fish...

Porbeagle shark-or at least I think that's what this is. It's from a bottom trawl in 2014 on the NOAA ship Bigelow. If I think about it Monday I'll try to confirm. I think the beast got frozen whole for the Smithsonian. For some reason I think it could be a salmon shark

when animals like sharks, huge rays or turtles get netted they usually get handled quickly and back over the side. There is a scale on the crane, and there are tag kits ready to put in quickly. The deck crew usually keeps the curious scientific staff safe and out of the way.

Thorny skate. I think the biggest I've seen myself was 10-15 pounds.

Here's some good info...
