from the article "Kollman found the low salinity system reduced his previously high mortality rates and that his dealership was able to greatly reduce chemical treatments and subsequent overdoses (Kollman, 1998). He concluded that a salinity of 14 to 15 ppt (1.010-1.011 SG) was an effective treatment level to which fish can be immediately transferred with no special acclimation procedures (Kollman, 1998).
