I Googled the above and didn't find much but did find this

 

"When the flash went off the fish convulsed and shot away in panic like it had been fired from a rail gun right smack into a limestone boulder. I will never forget the sound of pounds of flesh and bone hitting solid rock at that velocity. A lot of you have had the experience of feeling sound underwater, particularly lower frequencies. I felt that fish's head hit the rock and it resonated in my own head just a couple of feet away. The force and weight of the impact made a sound that still makes me wince."

 

Are there any studies? I've seen some comments about concerns around sea life that does not have eyelids.

A friend of mine published an article on the effects of flash photography on seahorse a few years back. It may be of some interest

Thanks SWink. Fasicnating especially this summary "The effect of underwater flash photography on H. whitei movements was not significant; however, the effect of handling H. whitei to take a photograph had a significant effect on their short-term behavioural responses to the photographer"
