SEAFWA 2015 has ended
Welcome to the technical sessions schedule for the 2015 SEAFWA Annual Meeting.

NEW THIS YEAR!
The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 2), track (i.e. Wildlife Technical Sessions), or session (i.e. Wildlife Session #1). You can also search for a presentation title (i.e. Changing Landscapes by Coalition), key term (i.e. striped bass), or presenter last name (i.e. Weaver). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer.

Cynthia N. Fox, J. Wesley Neal – Mississippi State University

Extended periods of low water can reduce fish abundance, redistribute fish within available habitats, and influence fish health. Reservoir drawdowns followed by drought events in Puerto Rico provided an opportunity to examine the effects of low water level on fish relative abundance, condition, and spatial distribution in Toa Vaca Reservoir. We sampled the fish community (α=0.1) using electrofishing and frame trawls in 2012 at normal pool (162 m above NVGD), and in 2013 following a prolonged water level decline. Largemouth bass catch rates were higher in 2013 (F=9.27, P=0.006) than in 2012, with bass distributions shifting to lower (F=13.80, P=0.006) and middle (F=10.46, P=0.012) sections of the reservoir. Relative weight of largemouth bass decreased from 103 in 2012 to 99 in 2013 (F=18.77, P
