10.  Photic Zone  How far light is visible through the water column.  Photosynthesis  Temperature  Dissolved Oxygen  Organisms

11.  Transparency has no effect on catch rates.  Transparency has no effect on number of species collected.  Temperature has no effect on catch rates.  Temperature has no effect on number of species collected.

12.  Temperature directly effects termination of spawning  Abiotic factors such as temperature are an important influence in habitat  Ongoing studies (A.L. Sheils 2005) (Whiteside and McNatt 1972).

13.  Trawl Net 8 ft Missouri type trawl Net 3.8 inch mesh 25 m rope  Hydro Lab  Secchi Disc  River Surveyor

14.  Recorded Temperature  Individual probes  Single Reading http://www.fws.gov/midwest/ashland/mtan/mtan51/images/Mar05- (2).jpg

15.  Measures Transparency of Water  Recorded at lowest point visible  Subjective www.uwosh.edu

26. Compare Summer River Run Trawl Data with ORSANCO Trawling Data. Trawl Lower Susquehanna River Using Same Protocols and Sampling Equipment Study Other Factors Effecting Trawl Outcome ( Velocity, Dissolved Oxygen, Boat Speed Etc.)

27.  Bathymetric and substrate maps using copper pole technique

28.  Dr. Tom Jones and lab  ORSANCO  Faculty and Students of BSC 662

29. Questions??

30. Questions???

31.  temperature and or secci depth show a pattern with number of specimens and darters per trawl  lower transparency shows a tendency for better trawl efficiency in benthic habitats

35.  ORSANCO trawling contract – 4 Specific pools - Montgomery - Willow Island - Greenup - Cannelton

36.  River Run 2007 – entire Ohio River  ORSANCO trawling contract – 3 Specific pools - Pike Island - Meldahl - Newburgh
