Book Description
Creel census surveys were conducted by the Bureau of Commercial Fisheries on the Connecticut River shad sport fishery during 1957 and 1958. In 1957 it was estimated that 34,310 shad were caught and kept in 19,901 fisherman days, and in 1958 an estimated 38,570 shad were caught and kept in 20,242 fisherman days. In 1958 the catch increased 12.4 percent, and the effort increased 14.1 percent over that in 1957. The average catch per fisherman day (1.7 shad) was identical for both years. The estimated sport catch for each year, 1941 through 1956, was determined by ratio estimate between catch at a state-controlled area and total catch for years 1957 and 1958.

Book Description
Abstract: The micro method of hematocrit is rapidly replacing red cell counts in clinical hematology. Observations were made on the value of this method in routine hematological examination of trouts. Under the conditions of data collection, the normal hematocrit values for brook trout were 45 to 50, for brown trout 39 to 44, and for rainbow trout 45 to 53. There was a close correlation between the hematocrits, red cell counts and hemoglobin. The commercial heparinized capillaries, while excellent for human blood, tend to give somewhat higher readings (7 to 18 percent) with trout, due to incomplete prevention of blood coagulation. The procedure as applied to trout is described in detail.
