Reproduction
The movement of the fish was determined to be less seasonal than dependent on water conditions directly before and after the monsoon season. This affects the spawning season and means that it may vary from any period between June and December. These fish only spawn once during the spawning season. The distribution of the fish throughout the spawning season is determined by the size and age of the fish. Many of the oldest, most mature adults between 17 and 19 cm spawn early in the season, while the juveniles of S. longiceps arrive to spawn later in the season. The peak period for commercial catch is June and July, when the juvenile fish have fattened themselves to prepare for their first spawning season. Rarely does S. longiceps survive a second spawn, but this is much more common in females.
