Chemical and histological studies of wild and hatchery salmon in fresh water
E. M. Wood, W. T. Yasutake, J.E. Halver, A.N. Woodall
1960, Transactions of the American Fisheries Society (89) 301-307
In a study of coho salmon (Oncorhynchus kisutch), the gross chemical and histological changes occurring over a 14-month period spent in fresh water were determined. The determinations were made at 3-month intervals on: 1) hatchery-reared fish, 2) fish hatchery-reared for 3, 6, 9, and 12 months and then planted in...
Ovarian fluid: Its role in fertilization
R.R. Rucker, J.F. Conrad, C.W. Dick
1960, Progressive Fish-Culturist (22) 77-78
FISH-CULTURISTs, in general, do not agree as to the time of actual fertilization of artificially spawned salmonid eggs. Some fish-culturists believe that the eggs are fertilized in the milt before water is added, while others are equally certain that fertilization is not achieved until after water is added. This difference...
A Virus-like disease of chinook salmon
A. J. Ross, J. Pelnar, R.R. Rucker
1960, Transactions of the American Fisheries Society (89) 160-163
Consideration is given to a recurring disease of early feeding chinook salmon fingerlings at the Coleman, California, Federal Fish Cultural Station. The infection becomes manifest in the early spring months at low water temperatures and abates as the water temperature rises. Bacteriological studies have failed to yield the presence...
National water resources and problems
Roy E. Oltman, Kenneth A. MacKichan, Glennon N. Mesnier, Frank H. Rainwater, Horace G. Thomasson
1960, Report
Water problems exist in all parts of the United States. Furthermore, the problems are becoming more acute and widespread as population and industry grow. The need is pressing for wider appreciation of the nature of water problems. This requires a background of basic facts about the occurrence of water, its...
Clutch size of the clapper rail
R. E. Stewart, B. Meanley
1960, The Auk (77) 221-222
Incidental information concerning the clutch size of the Clapper Rail (Rallus longirostris) was obtained during other studies of this species in the extensive salt marshes near Chincoteague, Virginia. Clutches were considered complete when repeated visits to the nest showed no additional eggs or when embryonic development could be clearly detected....
