Induced spawning of siban fish Cyclocheilichthys apogon using Ovaprim
Background: The objective of the present study was to examine the effect of Ovaprim dosage on the latency period, relative number of ovulated eggs, fertilization, hatching, and survival rates of the siban fish, Cyclocheilichthys apogon. Methods: Three dosages of Ovaprim were tested in this study, namely 0.3 ml kg-1 of broodfish body weight, 0.5 ml kg-1 body weight, and 0.7 ml kg-1 body weight, ...

The external appearance of brood fish has long been used to assess the stage of sexual development. In some species, males change in appearance during the spawning season (e.g., vivid breeding colors in cichlids, hooked jaw in salmon, and roughened texture of the pectoral fins or head of cyprinids). These physical changes make it relatively easy to identify sexually mature males. However, secon...
