The total cell numbers were counted using a hematocytometer. BALF cell smears were prepared using cytospin apparatus and stained with Diff-Quik solution (Sysmex Co., Kobe, Japan) to determine the differential cells counts in accordance with conventional morphological criteria.
The blood cell counts were determined by a hematocytometer. Three fish from each tank were randomly sampled at the end of the feeding trial and stored at -70[degrees]C for the subsequent proximate analysis of the whole body.
Viable and nonviable (blue cells) cells were counted on a hematocytometer (Marienfeld, Germany).
Rice bran particles and algal cells were counted using a hematocytometer. The feed volumes were calculated with the following formula modified from Alfonso (1993):
After 3-4 days of culture, the flasks were immersed in an ultrasound bath (Fisher Scientific FS6) for 3 min to detach the diatoms, which were counted using a hematocytometer to estimate cellular density and to calculate diatom densities to be used in the experiments.
Sperm motility was observed under optic microscope (250x) and recorded as percentage of motile spermatozoa in a determinate area of hematocytometer. Thus, motility was evaluated in sperm without treatment (CTR), spermatozoa incubated in cryoprotective solution but not freezed (ICS) and freezed-thawed spermatozoa (FTS).
