Strobe effects on fish

I am almost afraid to know the answer to this question but....

Has anyone seen any research on the effect of strobes on fish eyes or fish in general? Does it impact them in any way? Are they temporarily blinded and more open to predation while they recover? Do their pupils contract? Should I feel sympathy/emapthy and more importantly, am I stressing the poor jawfish who's just trying to incubate his eggs while I irradiate him with photons?

Just curious.

On a similar vein, does anyone know what type of fish the red filters are for on the z240s? Sorry for the slight hijack, but I'm off to manado on the 24th?

A joke, right?

The filter is reduce the effect of the aiming light when used in manual mode with the aiming light turned on.

Do a search on strobe effects. It's been covered many times before.

thanks Tim, to be honest I thouht it was something like that but when I was on the visions pool session one of the cameras underwater lads said that it was for certain species, but he wasn't sure which.

eta...Drew, the search facility on here never works correctly, bringing up countless threads that have nothing to do with eg strobe effects

I found them (red filters for aiming lights) helpful when shooting Mandarin fish in Lembeh.

They 'seemed' a lot less shy of the red filtered aiming light, than they did by the guides torch.

If I remember correctly, the modelling/aiming light extinguishes when you take a shot. BUT, it's been well over a year since I last used them. Hence the light should have no impact on your final image

Found some bumpf from Ocean Optics site - "The modeling light can stay on for 10 seconds per button press or be locked on. It cuts out automatically when you take a picture so as not to influence your shot. A red filter is included to let you work with shyer creatures that dislike white light"

All I get when I search for strobe effects are the 5 replies to this post. What should I be searching for?

Strobes do not seem to affect the sex lives of salmonid fishes!

Have tried all forms of light on mandarins, from Red filtered to Halogen to now LED. They didn't care. The males ... rise to the occasion no matter the illumination!
