Original language name
Stripped and testicular sperm of fresh and seawater tilapia, Oreochromis mossambicus.
Original language description
A significantly higher concentration of testicular spermatozoa was obtained from freshwater oreochromis mossambicus /9,9x10 spermatozoa ml/ than seawater O. mossambicus /4,6x10 spermatozoa ml/. The mean osmolality of the urine of freshwater fish /78,5 mosmol kg/ was significantny different that of seawater fish /304,8 mOsmol kg/ the mean lenght of the mid-piece of the spermatozoa together with the tail was more variable in freshwater O. mossambicus /8,80-0,23um/ than in seawater specimens /8,27+0,18/. Stripped sperm of freshwater O,. mossambicus was higly contaminated by urine wchich was a good activator of sperm motility in O. mossambicus held in both fresh and sea water. The osmolality for initiation of motility in freshwater Omossambicus spermatozoawas from 0 to 1022 mOsmol kg. The optimum osmolality for motility was from 70 70 to 333 mOsmolkg, for freshwater fish. In freshwater O. mosambicus spermatozoa the presence of 20 mM CaCl increased the permisive osmolality of NaCl from 184
