Abstract
The
objectives of this present study were to assess the effects of varying
dilutions, pH, temperature and cations on
spermatozoa motile parameters (SMPs) in fish Larimichthyspolyactis.
Optimal SMPs were observed when semen was diluted
in artificial seawater (ASW) at a ratio of 1 to 100, with temperature of 10oC
and pH 8.0. The spermatozoa of L. polyactis
were immotile in distilled water and motile in solution containing different cations. Maximum SMPs were
obtained in each solution containing 0.4 mol NaCl,
0.4 mol KCl, 0.2 mol CaCl2 and 0.2 mol MgCl2.
This study provides baseline knowledge of? L. polyactis
spermatozoa sensitivity of pH, temperature and cationic effects.
