1935c. Logically justified deductions con- 

 cerning the Great Lakes fisheries ex- 

 ploded by scientific research. Trans. 

 Amer. Fish. Soc. 65:71-75. 



Presentation of data to prove that 

 logically based assumptions and popu- 

 larly held beliefs are incorrect with 

 respect to the relation between mesh 

 size and the size and number of fish 

 taken, the relation between fishing time 

 and the catch of stationary gear, and 

 the role of pollution in the decline of 

 fish stocks in the Great Lakes.

1936b. Dr. Van Oosten reveals startling 

 data. Gold Medal Netting News 9 (May 

 1936):l-2. 



A discussion of mesh selectivity 

 stressing that the numbers and sizes 

 of fish taken in nets of a particular 

 nnesh size are not to be deduced on 

 mechanical grounds but must be deter- 

 mined from experimentation.

 5(11):1, 3. 



Discussion of unique and valuable 

 character of Great Lakes fisheries and 

 illustration from statistics for selected 

 species of downward trend in produc- 

 tion. Decline was attributed to over- 

 fishing made possible by the apathetic 



attitudes of State legislatures. (Article 

 based on talk given over NBC network.)

1936d. Net selectivity on the Great Lakes. 

 Gold Medal Netting News 10 (July 1936): 

 2-3. 



Continuation of article in May 1936 

 issue of same journal, introducing data 

 on relation of mesh size to: catches 

 of small trout and chubs in gill nets in 

 Lake Michigan; release of undersized 

 fish from shallow trap nets in Lake 

 Erie; and release of small whitefish 

 from deep trap nets in Lakes Huron 

 and Michigan.

1936e. The mortality of fish in Lake Erie. 

 Great Lakes Fisherman 1(3):2, 10; 

 l(4):2-3; also in Pa. Bd. Fish. Comm., 

 Combined Bien. Rep., 1938:92-100. 



Analysis of the species composition 

 of fish found dead on beaches of the 

 south shore of Lake Erie and a con- 

 sideration of the several factors that 

 may have contributed to the mortality. 

 Destruction of undersized fish in the 

 sorting of the catch of commercial 

 gears and the dumping of legal- sized 

 fish in poor condition are suggested as 

 the most important factors.

 fish of the Great Lakes. Trans. 2d N. 

 Amer. Wildl. Conf.: 605-612. [Reprinted 

 with slight changes of title and text in 

 the Progr. Fish-Cult., Memo. 1-131, 

 No. 28, 1937, p. 8-15.] 



General discussion of the subject, 

 with emphasis on the facts that corre- 

 lations have not been found between fry 

 plantings and the later take of fish and 

 that fish-culturists have underestimated 

 the effectiveness of natural reproduc- 

 tion and also have failed to consider the 

 true loss of eggs to the Lake (killing of 

 green fish, inefficient stripping . . .) at- 

 tendant on artificial propagation.

1937b. Doon-i of the Great Lakes fisheries. 

 Amer. Forests 43(3): 103- 105, 144-145. 



A plea for central control of the 

 Great Lakes fisheries, held essential to 

 bring about the restrictions on fishing 

 intensity necessary to put an end to the 

 progressive depletion of the stocks of 

 fish.
