Habitat use, migration pattern and population dynamics of chevron snakehead (Channa striata) in a rainfed rice farming landscape.
Habitat use, migration, mortality and growth of the chevron snakehead Channa striata in a rainfed rice farming landscape of north-east Thailand were studied through a tagging experiment. A total of 751 fish were captured, tagged and released during three distinct events in the late dry season, and in the beginning and at the end of the wet season. Rice fields provided the major wet season habitat for C. striata. Small trap ponds built to provide dry season habitat on farms provided 20% of catches and, if not harvested, could increase recruitment to the spawning stock by >30% despite accounting for
