| Summary: | clean a "Clean" water vs. "dirty" water. There is a "paradox" here: when the visibility is good, i.e. looking over the side of the boat one can see bottom in 10-15 fathoms - (the water is crystal clear) , then slubby conditions are at hand - the water is loaded with Oikopleura, the organism which produces the mucous, which when clinging to nets, is called "slub" ("slime" in Nova Scotia). Thus, clear water is "dirty", that is, contains slub. "Clean" water has a very poor visibility (contrasting with the above) and although it is "murky" due to phytoplankton and zooplankton, there are no _Oikopleura_ present. Hence "clean" water looks like it ought to cause problems but it doesn't.
