is one of the economically valuable food fish among indigenous
schizothoracids (snow trouts), inhabiting the Jhelum River system in Kashmir
along with other snow trouts of family Cyprinidae. The present study was
conducted to understand and bring forward various reproductive traits of S.
labiatus inhabiting River Jhelum.
Methodology: The investigation
was carried on 310 samples (221 males and 89 females) with total length and
total weight ranging between 143 to 350 mm and 62 to 449 g, respectively, for
a period twelve months.
index (GSI) was recorded maximum during April for both males (6.19) and
females (11.12), indicating that the fish fully matures during this month and
spawns during coming months i.e., May when the GSI values start decreasing
abruptly. The average values of absolute and relative fecundity in the fish
were recorded per gm body weight as 10323 and 42, respectively. Sex ratio was
found in 1:0.41 ratio, indicating a significant dominance of males over
opposite sex and Lm, i.e., length at first maturity was estimated
to be 196 mm and the corresponding age at this length was 2+ years. ??????
Interpretation: The fish breeds
once in a year in natural/wild habitat. These findings on reproductive
biology of the endemic snow trout, and the influence of environmental
conditions on breeding biology will serve as a baseline data towards planning
seed production and conservation strategies.
