Experimental rearing of steelhead trout at Hayden Creek ponds . Idaho - To determine maximum 

 stocking density for ponds under varied conditions, smolts from eggs of the spring mid-Snake 

 River steelhead trout runs are stocked at rate of 132,000 and 2.40,000 per acre and reared 

 over a 1-year period at the Hayden Creek ponds. Additional research is underway on production 

 of Chinook salmon at the same facility. 



Striped bass : 



Alabama AFC-1 E. Wayne Shell $30,000 



Research on striped bass in Alabama Rivers - Methods of cultiaring fingerling striped bass for 

 mass stocking at minimLun costs are investigated at Auburn University. Fingerlings are reared 

 on pelleted trout food and forage minnows in earthen ponds and metal troughs. About 575 of 

 the hatchery-produced fingerlings were marked with spaghetti tags and by fin clips and re- 

 leased in Mobile Bay and Alabama River to study survival, growth, and migration. 



Louisiana AFCS' 



-li/ James T. Davis $50,900 



Ecological factors affecting anadromous fishes of Lake Pontchartrain and its tributaries - 

 About .8,000 fingerling striped bass were released at four sites in the Tchefunote River to 

 evaluate the feasibility of establishing runs by planting hatchery-produced fish. 

 Alabama shad and Atlantic sturgeon were collected with traul and trammel nets in Lakes 

 Pontchartrain, Borgne, and Maurepas, and with hoop net and electrofishing in tributary 

 streams. 



Maryland 3-27-R Ted S. Y. Koo Completed 1968 



Tagging of .iuvenile striped bass. Roccus saxatilis (Walbaum) in Chesapeake Bay estuaries - 

 Aquarium tests were made on the suitability of Carlin, dart, and straight wire tags for 

 marking young-of-the-year striped bass. Several thousand juvenile striped bass were marked 

 and released in upper Chesapeake Bay, C&D Canal, and Patuxent River to study migratory 

 behavior and homing tendency. 



Mississippi AFCS-1-^ Gordon Gunter $55,000 



A study of striped bass, Roccus saxatilis. in Mississippi waters - Experimental stocking of 

 hatchery-produced fingerling striped bass is undertaken in the Pascagoula, Biloxi Bay, 

 St. Louis, and Pearl River systems to determine whether runs can be established in these 

 waters. Some of the released fish are marked with spaghetti tags to obtain life history 

 information. 



North Carolina AFC-1 , William W. Hassler $20,000 



The status, abundance, and exploitation of striped bass in the Roanoke River and Albemarle 

 So-und. and the spawning of striped bass in the Tar River. North Carolina - About 600 striped 

 bass are tagged and released in lower Roanoke River during the spawning season to estimate 

 popiolation size from catch returns. In addition, egg sampling stations are studied on the 

 Roanoke and Tar Rivers to obtain information on the time, duration, and extent of striped 

 bass spawning in each stream. 



North Carolina AFC-^ R. E. Stevens $20,606 



Factors affecting survival of immature striped bass - Fry and fingerling striped bass reared 

 in hatchery ponds fed primarily on Gyclcps ; therefore, the effects of certain chemicals 

 and environmental factors on zooplankton abundance are investigated. The limits of 

 water temperature, pH, and total dissolved solids at which immature striped bass 

 survive are studied.
