RATIO PENGENCERAN SPERMA TERHADAP MOTILITAS SPERMATOZOA, FERTILITAS DAN DAYA TETAS IKAN LELE (CLARIAS SP.)
ABSTRACT: This study was aimed
to determine the effect of the dilution ratio of sperm with optimal NaCl and
fructose on the motility of the catfish, Clarias sp., spermatozoa, fertility
and hatchability of eggs.
Catfish used in this study consisted of one parent pairs (male and female
weight of 1000 grams weight of 1500 g). NaCl and fructose solution were diluted
with aquabidest. The observation was conducted on the motility of spermatozoa,
fertility and hatchability of eggs. The experimental design used completely randomized
design (CRD). Dilution ratio is 1: 0, 1, 20, 1: 40, 1; 60, 1: 80, and 1: 100
with replicated 3 times. Observations were carried out soon after the sperm
mixed with diluents. Fertility occurred 12 hours after fertilization. Egg
hatchability was observed after fertilization.
The results showed that the ratio of dilution gave significant effect on
the sperm motility, fertility and hatchability of the eggs. This research found
that the dilution ratio 1: 60 was the best treatment with the average sperm
motility of 96. 66%, fertility of 71, 66 5% and egg hatchability of 70%.
Key words: motility, egg
fertility, egg hatchability, Clarias sp.
