9. Atlantic Salmon Restoration 



Restoration of the Atlantic salmon requires habitat restoration to provide 

 free migration for the adults and young. Migrations are influenced by obstruc- 

 tions, pollution, and nninimum flows. River drainages are inventoried in entirety 

 and this background information provides the basis for recommendations for im- 

 proving the runs. Electro-fishing on standardized test areas is conducted each 

 field seasbn to measure population trends in the young fish. Several weirs are 

 maintained and several traps are operated in fishways. Research is confined 

 to a year around operated counting weir on the Edmunds Unit of the Moosehorn 

 Wildlife Refuge, and a unit productivity study on a tributary to the Penobscot 

 River. The hatchery stock necessary for introductions to restored areas is 

 obtained and reared by the Fish and Wildlife Service at their East Orland Fish 

 Cultural Station. Hatchery fish are marked prior to stocking.

 of Maine; began July 1948; $22,000; W. Harry Everhart, Leader; reports

10. Chemical Reclamation of Small Ponds for Trout 



Natural ponds open to public fishing will be chemically reclaimed with 

 rotenone compounds and subsequently managed for trout to improve the quality 

 of fishing. 



U. S. Fish and Wildlife Service cooperating; statewide; began 1955, con- 

 tinuing; $17,000; Robert E. Foye, Leader; reports available.

1. Atlantic Salmon Investigations 



This is a cooperative study of the estuary of the Sheepscot River to deter- 

 mine its importance in relation to Atlantic salmon. Studies include currents, 

 salinity, river discharge, temperature, bottom fauna, alewives, smelt, 

 herring, clams, marine worms, as well as salmon. River studies include 

 estimation of spawning population and determining time and extent of seaward 

 migration of smolts by means of an upstream-downstream weir which was 

 installed in 1956.

 Leader; reports available.

1. Study of Fish Movements 



The objectives are: (1) To develop a technique for following moving fish, 

 and (2) to use this technique to learn movement patterns of fish in impound- 

 ments, especially Deep Creek Lake, to permit more intensive harvest of these 

 fish.
