I went through this forum, and found out it's the best place for a question that bugged me for a long time.
How can fish defend themselves from decompression?
A fish fast ascending from 60 feet when completly saturated, should have quite a problem when reaching 3 feet.
I had a talk about this with a friend and we came to several defferent ideas about it-
-Decompresion is not as dangerous for fish as for mammals, as their blood system works diferently.(my favorite).
-the amounts of N2 dissolved in the water are not enough to couse it (seems to me phisicaly not right, as it is suposed to have the same ratios as in air. if the oxigen is enough to sustain life, the N2 should pose a problem).
-the gill system absorbes only O2 (also dosent seem right to me).
-Fish tend to stay in a relatively restricted area of depths (my second favorite).
I guess it can also be a mixture of the first and last.
I also know of a certain kind of embolism that affects fish, and would like to know more about it.
