Fish Community Structuring in the Restored Hobble Creek Delta : Chad Landress, Utah Division of Wildlife Resources The Importance of Intrinsic Physical Habitat, Flood Dynamics and the Detection of Juvenile June Sucker (Chasmistes liorus) Background and Need How do we get from this to this? Background and Need Old channel was not used by June sucker Lack of gradient Lack of gradient Debris jams Debris jams Diversion structure Diversion structure Poor habitat within straight levees Poor habitat within straight levees Background and Need Completed in November 2008 Converted a 21 acre field into a dynamic delta Methods Vegetation: emergent emergent submergent submergent filamentous algae filamentous algae woody debris woody debris Results MarchAprilMayJuneJulyAugustSeptemberOctoberNovember 1 southNNNNNNNNN 2a southYYYYYYYYY 2b southYYYYYYYYY 3 south*YYYD (6/28)NNNNN 4 southYYYYD (7/10)NNNN 5 south*YYYYD (7/10)NNNN 1 northYYYYD (7/4)NNNN 2 northYYYD (6/5)NNNYY 3 northNNNNNNNNN 4 northNYNNNNNNN 5 northYYYYD (7/7)NNYY 6 north*YYYYD (7/7)NNYY 7 northYYYYYD (8/20)NNN Timing of disconnection/reconnection with main channel * pond where June sucker were detected Species, number, and relative abundance of fish captured at Hobble Creek restoration area 2010, cumulative catch Non-metric multi-dimensional scaling of fish community structure in Hobble Creek restoration ponds Dominance, diversity and evenness of potential sucker ponds * pond where June sucker were detected Initial Conclusions Water temperature Water temperature Food supply Food supply Vegetative cover Vegetative cover Flood dynamics structure initial communities Flood dynamics structure initial communities Carp, vegetation, and predators Carp, vegetation, and predators Acknowledgments: June Sucker Recovery Implementation Program June Sucker Recovery Implementation Program Russ Rader Russ Rader Melissa Stamp Melissa Stamp David Tinsley, especially his eyes which spotted a lone June sucker in a seine with thousands of other fish and copious algae.
