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"

Looks like New Jersey ballyhoo

Keep em comin

Four spotted flounder. With all the trawls I've seen pulled up in the Raritan bay/Sandy Hook bay and nearby I really haven't seen many of these. Most of the fish I've seen have been from the NOAA Bottom Trawl survey.
This fish was from Raritan Bay. They don't get large, they don't get thick, they are predators with teeth. I think the largest that I've seen was about 15". Generally they are found in deeper water although they can be caught from the surf.
The second image I took from a UMass website of a professor that I've sailed with...
I even had some trouble finding a link to good info on the species
this is sparse.

Lumpfish. These are odd fish even in my book(though they are cute- I don't say that about many fish). They have a sucker like disk on the underside which allows them to attach themselves to objects. They really resemble a football like shape and the temptation could be to punt them over the side. They are a bit squishy like a Nerf football. They vary in color from green to blueish.

I've seen them most during bottom trawl trips up north of NJ but have caught them up in the water column with a mid-water trawl looking for herring.


They can be used for their eggs-caviar!

Agreeing with everyone John. Great thread! Some cool info for sure!
