Gyrodactylus stableri

Gyrodactylus stableri on the fin of the plains killifish Fundulus zebrinus; filmed in western Nebraska. Pictures were shot using a Nikon AlphaPhot teaching compound microscope with a trinocular head and a mounted camera. Ill shoot some scales and post them separately as a short video. Lowest mags were with a 4X objectives, next mags with a 10X objective, and highest with a 40X objective. The camera tube has no separate eyepiece lens. Thanks for the suggestions!

The setup is a Nikon AlphaPhot with video camera attachment. Some of it is shot with a 40X objective, although the attachment probably acts like an extension tube and ups the magnification. The highest mag video is with the 100X oil immersion objective. The camera is Microimage Video Systems model YC/NTSC (I'm not sure these are made anymore). Thanks for the comment!

Thanks, SDK. I remember that some years ago G. stableri had been moved to a different genus, so thanks for the reminder. Seems like it was Swinglia or something like that before Fundulotrema. This summer we didn't do much work with Fundulus, and those populations are a little distant, but certainly by this time a year from now I'll have some in EtOH for you. Thanks again!

wow

but, how can i take such a video? a microscope of 1000x and what ?

I love the video. It really shows the behavior and morphology quite well. Gyrodactylus stableri has since been moved to the genus Fundulotrema. If you have any fixed in etoh I would love to talk. P.S. love "Foundations"!
