Fish Spawning Season Analysis
Certain physical parameters of water such as turbidity, water
temperature, dissolved oxygen, free carbon-di-oxide and total
alkalinity also studied to examine the effect of these abiotic
parameters on gonadal maturation.
It was observed that in both aquarium and pond condition the
species spawns four times in a year, between March and October,
when temperature was favourable spawning activity of the species
has not been observed during winter (November to February) when
water temperature drops down below 18°C. It has further been
noticed that seasonal peaks in the G.S.R. values coincided with the
peaks in the percentage of occurrence of matured individuals. The
result on GSR indicates that both the males and females mature at the
same time of the year, the peak breeding period being June and July.View entire presentation
