3 Objectives Assess habitat utilization of Gulf sturgeon along Ship Island and at Camille Cut (i.e., project zone) by monitoring acoustically tagged individuals before (baseline), during (construction phase) and after the filling of the Cut (post-fill). Approach evaluated at two different levels: Coarse scale assessment to determine the relative occurrence of Gulf sturgeon within the project area. Fine scale assessment to address more specifically what Gulf sturgeon are doing within identified areas. YEAR 1: 14 April May 2011 (21 telemetry receivers); no detections. YEAR 2: 20 September June 2012 (21 receivers); 13,720 detections, 14 Gulf sturgeon.

6 YEAR 3 Deployment period: 13 September June Downloaded at 3-4 week intervals. 94,244 total detections logged (not corrected for simultaneous detections). 21 Gulf sturgeon documented on the array. Pearl River (n=6) Pascagoula River (n=4) Escambia River (n=1) Blackwater River (n=3) Yellow River (n=2) Choctawhatchee River (n=1) Brothers River (n=4).

The number of detected Gulf sturgeon was greater during the deployment period but the distribution of detected individuals by river of origin was similar between deployment periods, except for the inclusion of individuals from drainages representing the eastern portion of the species range (i.e., Choctawhatchee and Brothers rivers).

32 On the radar. Continue telemetry based assessment (pre-construction, construction, post-construction). Refine the benthos assessment applied to the deployment period (e.g., reevaluate metrics for defining high/low categories). Refine and finalize description of important prey items (applicable to other regions Pascagoula estuary). Apply new approach to current benthos dataset. More detailed evaluation of detection history of individual fish to identify movement patterns (i.e., corridors) in comparison to longduration residency areas (i.e., feeding).
