We (the royal "we" meaning Kelly Benoit-Bird's group from Oregon State) have three fishing stations on the port side of the back deck.
|This animal still has lots of energy even out of water. When we first pulled it out, it was inking/squirting everywhere.|
|Various parts of the squid that we are measuring.|
|A dissected myctophid, the balloon-like structure in its body cavity is its swimbladder (probably over-inflated due to us bringing it up from depth). Other internal organs have been removed so we can measure the swimbladder.|
In addition to the squid, we've been examining other animals we catch in the net (as you've seen previously). One of the most interesting animals we catch regularly are myctophids which are small fish that spend most of their time in the middle of the ocean (i.e. hundreds of meters deep). These animals were first observed (acoustically) over 60 years ago, and we still know very little about them. They have a swim-bladder (an air or wax filled organ) inside of them which 1) helps them maintain their buoyancy in the water column and 2) scatters a lot of acoustic energy. We've been dissecting the animals that we catch and measuring their swim bladders to better understand our acoustic backscatter data.
We've been busy the past few days with lots of measurements and Chad just caught a hake (on a squid jig) so it's back to the wet lab.
