As this looks like a compendum of exciting research emerging at LILA, I wonder if there are any reports or pubs on the work done on fish movements, habitat selection and seasonal hydrology here in 2011- ?
Most fish live in local places during the dry season. During the wet season, for example cat fish migrates up river to desovates up there while for example trout remins in local places by avoiding the force of the river discharge living in steady ponds usually found besides the main river channel. In this way trout does not spend too much energy dealing with the force of the river discharge during the wet season. There are of course very many differences of the local fish species and the magrating fishes in different places.
