Humans, it is now known, suffer from a variety of maladies all correlated to low serum vitamin D, but no 'direct proof'. When they get old, they fall and break their hip's. In fact, what has been discovered is that their hip broke, and they then fell, due to osteomalacia. Guess what? In children it's called...RICKETS, or 'a softening of the bone due to inadequate calcification/mineralization'. Many of them meanwhile, had also been suffering from colds/flu, cancers, cardio-vascular disease, neurdegenerative disease, alzheimers and autoimmune disorders. All of these apparently due to low vitamin D. There was an underlying structural/bone issue all along, while these other diseases popped-up appearing to be unrelated, when in fact they are. With fish, most of us simply don't have them long enough for any bone disease to manifest itself, only the 'other' diseases we deal with commonly-IMO.
I am suggesting</em> that Lateral Line Disorders in fishes 'may' be a form of autoimmune disease. Captive fish have been shown to be more susceptible to disease in general. Many have posted on here that they found reducing stress to help with treatment of a variety of fish disorders. This, to me, speaks of a possibly comprimised immune system (organisms on the edge, so to speak).
These fish that get' Hole in the Head' or Head and Lateral Line Disease (or HLLD), often do so with a lack of any other explaination. This type of syndrome is mirrored in human and</em> other animal diseases (lack of apparent cause). I'm a 'root cause' kinda guy. I believe there is always a smoking gun. Like I said in an earlier post, "it's starting to smell like gunpowder".
In my research, I discovered that most vitamin D in the oceans is produced via phytoplankton. This source is then passed along, up the food chain. I don't know many that are maintaining healthy populations of phytoplanktors in their tanks, though many of us dream of it. It may be possible to supplement via nori, etc.
It's interesting to note that fish oil has significant amounts of vitamin D.
