1. Yallowtail Study (FA: F-l-R). 



Studies are being made as to the best techniques to be used in tagging yellowtail and 

 in determining the age of specinnens taken. AH possible data on reproduction and 

 food habits are being gathered. Efforts are being made to determine the areas 

 in which young fish occur and their rate of growth. Data on oceanographic condi- 

 tions which appear tied in with the yellowtail distribution and nnovements will be 

 recorded. 



Along the Southern California coast and adjoining Mexican waters; The Scripps Insti- 

 tute of Oceanography cooperating; began July 1, 1952, planned for 3 years;

2. A Study of the Catfish Fishery of California (FA: F-2-R). 



The objectives of this study are to determine the reasons for the apparent decline in 

 catfish fishery. Information on population numbers, life history, and rate of re- 

 ciuitinent of the more important species are being studied. At least 9,000 fish 

 are to be tagged employing several methods. Efforts will be made to recover the 

 tags and analyze all available data.

3. Experimental Back-country Fish Management (FA: F-3-R). 



This study aims to evaluate the potentialities of a large number of streams and lakes 

 for public fishing in the higher country of northern California and the Sierra 

 Nevada. It provides a means of keeping a running account of fish populations, 

 harvest, and the steps which might be taken in improving the habitats for fish. 

 The State's trout stocking program will be modified along lines indicated by this 

 investigation and various types of developmental work will be carried out when 

 practicable. 



Headquarters at B shop; began July 1, 1952, planned for 3 years; $13,000; Scott M.

4. North-coastal Stream Restoration and Innprovcment (FA: F-4-D). 



California is continuing activities directed toward the improvement of conditions for 

 migrating and spawning fish in its coastal streams in the northern part of the State. 

 Removal of log jams and natural barriers and deepening of riffle areas will be 

 undertaken. 



The Smith and Klamath Rivers in Del Norte County and the Elk, Mad, Eel, and Garcia 

 Rivers in Humboldt County; began July 1, 1952. planned for 10 years; $37, 708. 47;
