Pennsylvania AFCS-li' David Daniels Extended 



Feasibility study of the restoration of shad runs in the tributaries of the Delaware River 

 estuary - Fertilized shad eggs were placed in hatching boxes throughout the Pennsylvania 

 section of Brandywine Creek, tributary to Delaware River, to determine the suitability of 

 the stream for restoration of American shad. 



Pennsylvania AFC-^i David Daniels $15,000 



Restoration of shad runs in the Brandywine Creek and its tributaries - This is a joint study 

 with the State of Delaware to restore shad runs in Brandywine Creek by building ladders at 

 dams and transplanting fertilized eggs in upper reaches of the stream. 



Groundfish : 



Maryland 3-21-R Ted S. Y. Koo Completed 1967 



Determination of the distribution and abundance of the winter flounder, Pseudopleui-onectes 

 americanus - Adult winter flounder were caught from November through May in deep or channel 

 hauls with trawl throughout Chesapeake Bay and river mouths, except in lower Patuxent River. 



Massachusetts 3-38-R Allen Petersen Completed 1969 



Identification of winter flounder subpopulations - Tagging information is evaluated and ex- 

 perimental otter trawl data are analyzed to define the limits of the winter flounder 

 populations along Massachusetts coast. 



Massachusetts 3-87-R Phillip G. Coats $23,i00 



Winter flounder investigations - Knowledge of the contribution of estuarine winter flounder to 

 the offshore fishery is needed to effectively msinage and regulate this important fishery. 

 Populations of juvenile and subadult flounders will be estimated by mark-and-recapture 

 methods. Stratified random sampling with an otter trawl and plankton samples will be 

 made in a selected area in Nantucket. Several types of tags for juvenile winter flounder 

 will be evaluated under controlled conditions. 



Oregon l-/i-R Robert L. Demory $27, 977 



Investigation of the abundance and recruitment of Dottcmfish off ('regon, with emphasis on 

 D over sole - Data on fluctuations in abundance and year-class strength of Dover, English, 

 and petrale soles and Pacific ocean perch are evaluated. Techniques for determination of 

 spawning success and abundance are investigated also. 



Washington 1-22-R Gene DiDonato $72,000 



Monitor condition of certain groundfish stocks. Washington trawl grounds - To obtain infor- 

 mation on stock identity and migratory behavior of English sole, Pacific cod, and petrale 

 sole, 5,000 to 10,000 fish of each species are tagged and released and biological data 

 collected. The information obtained will be useful in international fishery negotiations. 



Pacific salmon : 



Alaska 5-^-R Daniel P. Hennick $76,500 



Pink salmon forecast research - Each season the abundance of preemergent fry of pink salmon 

 is sampled in about 25 streams in Kodiak area, 12 in Cook Inlet area, and 100 in southeastern 

 Alaska. Based on an abundance index, annual forecasts are made of size of returning adult 

 runs. The optimum escapement for selected streams is alco .studied. 



Alaska 5-5-R Robert Panlus . 



Kvichak River smolt study - Smolt counts are made as indexes for predicting the size of the 

 returning sockeye salmon run and for estimating the optimimi escapement for the Kvichak River 

 of Bristol Ray area.
