1. Pulp Paper Waste Pollution Abatement. 



Objective of the project is to develop a satisfactory chemical recovery 

 method for the spent liquor from the cold soda semichemical pulping process 

 and the neutral sulfite semichemical pulping process. The development of 

 an efficient and economical recovery process would measurably reduce the 

 poUutional characteristics of the mill effluent. 



Began July 1950, continuing; $5,000; P. K. Baird, Leader; reports available.

1. Fluctuations, Interrelationships and Movements of Fish Populations. 



The objective of this project is to follow the fluctuations in the age, growth, 

 size, and abundance of the different species, commercial and non-commercial; 

 and to ascertain through nnarking experiments and morphological studies whether 

 local races and stocks exist, and the extent of movements and intermingling of 

 different segments of the populations. 



Lakes Huron, Superior, and Michigan; hdqrs. Sturgeon Bay; began 1947, 

 continuing; Leonard S. Joeris, Leader.

 Investigations, 1220 East Washington Street, Ann Arbor, Mich. 



2. Limnology of Green Bay. 



The objective of this project is to make a limnological reconnaissance with 

 special reference to physical conditions- -seiches , temperatures, currents--in 

 the hydrographically complex control region in relation to the distribution and 

 movements of fish.

Lake and Stream Surveys and Inventories. 



A card file is kept on all lakes and streams in the State with reference to 

 their physical and chemical conditions, their planting records, their census 

 records and other pertinent information. Surveys at regular intervals thus 

 furnish a means of making comparisons upon which management plans can be 

 based. Such surveys and inventories also include newly developed waters and 

 waters on which there has previously been insufficient information. 



Statewide; began January 1, 1951, continuing.

Lake Rehabilitation, Reclamation and Rough Fish Control. 



Objectives of the project are to eradicate all fish species in certain lakes 

 where a complete new start is indicated as the best management procedure; to re- 

 duce by seining or rotenoning rough fish populations in lakes and reservoirs from 

 which they cannot be completely removed; and to carry on a seining program 

 through connmercial seiners for further rough fish control. Complete eradication
