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. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference.

A New Frontier: Establishing Hybrid Striped Bass in Lake Norman, North Carolina

N. Corey Oakley, North Carolina Wildlife Resources Commission

Lake Norman has had numerous introductions of non-native fish. These introductions have had various effects on established fish populations in the reservoir. Alewife Alosa pseudoharengus and Blueback Herring Alosa aestivalis (river herring) introductions of the mid 1990s caused a decline in the Striped Bass Morone saxatilis fishery. Striped Bass foraged on river herring in the hypolimnion of Lake Norman during summer months each year. As the metalimnion becomes hypoxic during the summer, Striped Bass become trapped in the hypolimnion and eventually die when it becomes hypoxic. Striped Bass fish kills have become more frequent and severe since 2004. In 2013, the North Carolina Wildlife Resources Commission began replacing the Striped Bass fishery with a hybrid Striped Bass (M. saxatilis X M. chrysops) fishery. Biologists expect that hybrid Striped Bass will not inhabit the hypolimnion during summer months and have better growth, condition, and survival than Striped Bass in Lake Norman. Angler and gill net data from 2014 indicate that hybrid Striped Bass are growing rapidly and exhibit average condition during the first two years of life. Fish captured weigh between 1,200–1,700 g. Rapid growth of hybrid Striped Bass has increased the popularity of the new fishery. Growth rates, condition values, severity of fish kills, and frequency of escapement will be the criteria used to determine if the new hybrid Striped Bass fishery is successful at Lake Norman.
