Can anyone tell me what affects can get if you keep it at a low salinity for a long period of time. Like say 1.020 for lets say almost a year? I know that cephalopods do best at full strength sea water. I'm just curious what affects would lower salinity close to 1.020> would have on an animal. If anyone has any input it would greatly be appreciative or if anyone knows of any literature I could read that would be great too. Also how does calcium levels affect cephalopods in general? Is higher or lower levels better?
