have modified the biota; more valuable 

 fish species have become scarce, and 

 less desirable ones are nnore plentiful.

 ductivity nneasurements. Limnol. 

 Oceanogr. 7(3):330-334. 



The usual methods of converting 

 conductance measurements to a given 

 temperature have not yielded uniformly 

 accurate results because the coefficient 

 varies according to concentration and 

 kind of electrolytes, temperature at 

 nneasurement, and temperature to which 

 adjustment is made. Precision requires 

 determination of temperature coeffi- 

 cients for each water studied. Principles 

 involved are illustrated by data from 

 seven natural waters.

1964a. Status of the deepwater cisco popu- 

 lation of Lake Michigan. Trans. Amer. 

 Fish. Soc. 93(2):155-163. 



Long-term trends in the population 

 of ciscoes or chubs ( Leucichthys 

 [ Coregonus ] spp.) are reviewed, and 

 detailed attention is given to the syste- 

 matic sampling of 1930-32, 1954-55, 

 and 1960-61. The trend toward increas- 

 ing dominance by the bloater (hoyi), 

 which started with the destruction of 

 lake trout by the sea lamprey in the 

 1940's, carried the percentage of that 

 species in gill net samples from 31.0 

 in the 1930's to 76.1 in the 1950's, 

 to 93.6 percent in 1960-61. Abundance 

 of other chubs has been sharply re- 

 duced, and two species ( johannae and 

 nigripinnis) may be extinct.

1964b. The taxonomic status of Leucichthys 

 macropterus , a cisco of Lake Erie. 

 Copeia 1964(1):230. 



A reexamination of the type speci- 

 men proved that L. macropterus was 

 in fact a shallow-water cisco (L, artedii) 

 with abnormally long fins. The count of 

 30 gill rakers on the first arch, given 

 in the original description, was based 

 on a poorly excised arch. The same 

 arch on the other (left) side had 47 

 rakers. The long fins did not offer a 

 sound diagnostic character as fish with 

 excessively long fins, though rare, are 

 by no means unknown among 

 coregonids.

 Trans. Amer. Fish. Soc. 89(2):193- 197. 



Pontoporeia affinis was dominant in 

 63 bottom samples from both deep and 

 shallow water. Next most abundant in 

 deep water were oligochaetes, finger- 

 nail clams, and midge larvae; the midge 

 larvae outnumbered the oligochaetes 

 and clams in shallow water.

1959. Food of yellow perch, Perca flaves- 

 cens (Mitchill) in Saginaw Bay, Lake 

 Huron. Trans. Amer. Fish. Soc. 88(4): 

 330-331. 



Of 241 yellow perch, 2.5 to 8.5 inches 

 long, 170 had stomachs containing food. 

 Immature insects (tendipedid larvae 

 and pupae; mayfly nymphs) were im- 

 portant for fish of all sizes and made up 

 26 percent of the volume. Cladocerans 

 ranked second (22 percent of the vol- 

 ume). Other foods of consequence were 

 Gammarus , snails, fingernail clams, 

 and copepods (the last especially infish 

 2.5-2.9 inches long). Fish (alewives) 

 were eaten by only II perch, but perch 

 longer than those in sample are known 

 to feed heavily on fish.
