82 FISH AND GAME. 



(1) The food of the economic lamellibranchiate mollusks, in- 

 cluding a brief study of the value of certain Massachusetts waters 

 for the production of shellfish. 



(2) A shellfish compend, which gives briefly the practical 

 problems of quahaug, clam, scallop and oyster culture. 



(3) A general treatise on the diseases of game birds, including 

 observations upon various types of infection on game farms. 



(4) The fresh-water ponds of Massachusetts, their natural 

 conditions for the sustenance of fish life, their possibilities of 

 development, and their adaptability for stocking with food and 

 game fish. 



(5) The trout brooks of Massachusetts, including a brief 

 description of the more important water systems of the Com- 

 monwealth, with a plan for the systematic stocking and de- 

 velopment of their latent possibilities for food production. 



(6) The Massachusetts alew r ife fisheries, their decline, present 

 condition and a proposed plan for the re-establishment of the 

 same, such as is outlined in the following pages. 



Bird Diseases. - - The study of certain bird diseases which have 

 proved a menace at the State game farms has been continued 

 and the preliminary investigations have been further extended 

 particularly in respect to avian tuberculosis. There is urgent 

 need for this type of work, since the future success of State and 

 private game farms depends upon the elimination and prevention 

 of destructive bird diseases. 



Inland Waters. Additions have been continually made to the 

 systematic survey of the inland waters, both ponds and streams, 

 which was begun in 1911. During 1911 and 1912 the majority 

 of the State ponds were examined by members of the biological 

 staff in respect to their natural conditions and qualifications for 

 fish production. In 1914 the work was further extended to the 

 streams, which were classified as suitable or unsuitable for stock- 

 ing with trout or other fish. During the past year our records 

 have been enlarged by the addition of new streams and ponds 

 and by further facts concerning those already examined. In 

 Massachusetts there are a large number of excellent fishing ponds 

 of artificial construction, which do not come within the legal 

 definition of State ponds, but on which the public is allowed to 

 fish by the owners. Plans are under way for the investigation 

 of this class of ponds, since they afford a good field for stocking, 

 provided that the written consent of the owner of the pond to 

 permit the public to fish thereon is given.
