Bulletin of Marine Science: Ingenta Connect Table Of Cont...

The proceedings for the #FishAtNight symposium (nocturnal fish behavior and fisheries) are now online www.ingentaconnect.com/content/umrsmas/bullmar/...

I met Jeff at #FishAtNight and have been dying to write about his work for a year and a half- glad I could finally make it happen!

Loved #FishAtNight but will not be attending tomorrow morning's sessions so I can get some work done.

Now we have a one-hour mini film festival organized by @Waves_FilmFest at #FishAtNight !

Lots of oooooos and ahhhhhhhs from the #FishAtNight audience at @JeffMilisen 's amazing photos of epipelagic fish

#FishAtNight @JeffMilisen :Blackwater dives allows you to see how these animals interact in the wild, which you can't with a plankton trawl

#FishAtNight @JeffMilisen :Many fish larvae are mesopelagic, which means they can be seen on these blackwater dives

#FishAtNight @JeffMilisen :Shining lights from the dive boat means that some animals avoid them, but still see a lot

#FishAtNight @JeffMilisen : About 70% of pelagic diversity off Hawaii is gelatinous, which can't be sampled via plankton net

#FishAtNight #JeffMilisen : Jeff uses being clipped to a drifting boat like a transect survey, just tracks what passes in front of him

#FishAtNight #JeffMilisen : Divers are clipped to lines attached to the boat for safety (my willingness to blackwater dive just increased)

#FishAtNight #JeffMilisen : Every mile offshore in Hawaii, it gets about 1,000 feet deeper. Easy to access deep water.

#FishAtNight #JeffMilisen : Diving off Hawaii, at night, in thousands of feet deep water. "Blackwater diving"

#FishAtNight #JeffMilisen : Plankton nets damage gelatinous animals like ctenophores, siphonophores, jellyfish. Hard to identify "goop"

#FishAtNight has been fantastic, congrats to @BullMarSci @UMiamiRSMAS @SJC_fishy @DrNeilHammer @JollyGreenGeoff for organizing!

(This is the last #FishAtNight talk I am attending, though the meeting goes through tomorrow morning. I'll RT some of those tweets at lunch)

The last #FishAtNight talk of the day is by @JeffMilisen , "diving into pelagic diversity," about black-water SCUBA diving!

#FishAtNight Whitmarsh: Differences between sites can't be due to gear differences "because I just borrowed their gear" #OverlyHonestMethods

#FishAtNight Whitmarsh: Red light showed more natural assemblages, while blue light attracted species like snapper to BRUVs

#FishAtNight Whitmarsh: Fewer species were observed with red light than with blue light BRUVs

(This is the least technical difficulties with playing videos I've ever seen at a conference, kudos to the A/V staff on this) #FishAtNight

#FishAtNight Whitmarsh: Studied whether different colors of light would be more or less disruptive to studying fish at night w/ BRUVs

#FishAtNight Whitmarsh: Baited video can be a great way to assess biodiversity, but doing it at night requires light which affects behavior

The next #FishAtNight talk is Sasha Whitmarsh, "the effects of light color on fish assemblages observed at night via baited video"

#FishAtNight @HeatherSpence : Marine protected areas sometimes ban fishing, but there's still a lot of boat noise. Harmful to fish?

#FishAtNight @HeatherSpence : Boat noise greatly exceeds fish noise, drowns out important communications between fish

#FishAtNight @HeatherSpence : Noise made by fish pretty similar month to month. Environment noisy in daytime (boat traffic)

#FishAtNight @HeatherSpence : By listening to fish in darkness, don't need to disturb their behavior by introducing light

#FishAtNight @HeatherSpence : There is an order of magnitude less research on the Meso-American barrier reef than on the great barrier reef

#FishAtNight @HeatherSpence :meso-American barrier reef is the largest reef system in our hemisphere but great barrier reef much more famous
