| description |
Scanty information is known about the biological aspects of Cyclocheilichthys
apogon and as such, a study on the biology this species was conducted in five
tributaries of Muda Reservoir for 18 months from March 2014 untill August 2015.
Monthly sampling was conducted to collect the water samples and fish specimens.
This study includes the determination of the physico-chemical water quality
parameters, length-weight relationships and relative condition factor of C. apogon,
population parameters, feeding and reproductive biology of C. apogon. No significant
differences (p > 0.05) were observed among sampling stations in pH, nitrite, nitrate
and ammonia concentration and no significant differences (p > 0.05) were observed
in water temperature, conductivity, water depth, dissolved oxygen, total dissolved
solid, current flow, nitrate and phosphate concentration among sampling months. All
the values of the physico-chemical water quality analysis in tributaries of Muda
Reservoir were in safe level in Class I and IIA. C. apogon was found to grow in
isometric growth pattern using the length-weight relationships. The values of relative
condition factor of C. apogon was higher than one shows the better condition of C.
apogon in this tributaries. From the population parameters study, C. apogon was
estimated to reach length infinity (L∞) at 21.5 cm, with moderate growth rate (K) of
0.42 year-1. The length at first capture (Lc) of C. apogon was estimated at 8.67 cm. |
