Lake trout fin-clipping rates at two national fish hatcheries
Merryll M. Bailey
1965, Progressive Fish-Culturist (27) 169-170
The successful stocking of the hatchery-reared lake trout (Salvelinus namaycush) in Lake Superior has imporved the outlook for rehabilitating stocks reduced to an extremely low level by predation from the sea lamprey (Petromyzon marinus). Marking the fish by fin-clipping to determine growth and survival benefits from holding young-of-the-year lake trout...
The water story in Central Iowa
F. R. Twenter, R. W. Coble
1965, Iowa Geological Survey Water Atlas 1
"The general welfare of the people of the state of Iowa requires that the water resources of the state be put to beneficial use to the fullest extent of which they are capable."  This can be achieved only by a knowledge and understanding of the water resources - their use,...
Surface water records of Texas, 1964
U.S. Geological Survey
1965, Report
The surface-water records for the 1964 water year for gaging stations, partial-record stations, miscellaneous sites, and base-flow studies within the State of Texas are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed...
Characteristics and pathogenicity of a capsulated Pseudomonas isolated from goldfish
G. L. Bullock
1965, Applied Microbiology (13) 90-92
Characteristics of a capsulated bacterium isolated from an epizootic among goldfish (Carassius auratus) were determined as well as the ability of the bacterium to produce experimental infections. The bacterium was found to be a gram-negative rod which oxidized carbohydrates, produced green fluorescent pigment, and otherwise seemed to fit into the...
The black-spot (Uvulifer ambloplitis: Trematoda: Strigeoidea) of centrarchid fishes
G. L. Hoffman, R.E. Putz
1965, Transactions of the American Fisheries Society (94) 143-151
Adult Uvulifer ambloplitis were recovered from a kingfisher and the worm eggs were incubated. Helisoma snails were infected with the resultant miracidia. Cercariae, very similar, but not identical to Cercaria bessiae, were recovered and used to infect fish. It was possible to infect Lepomis macrochirus, but not Catostomus commersoni, Cottus...
A new Rosalina (foraminifera) parasitic on a bivalve
R. Todd
1965, Deep-Sea Research and Oceanographic Abstracts (12)
In a collection of pelecypods from deep water off the west coast of Africa, several specimens of a new species of the foraminifer, Rosalina, are attached to the umbonal area of the bivalve. In addition, numerous attachment scars are observed on the exterior...
Vacuum-jacketed hydrofluoric acid solution calorimeter
R. A. Robie
1965, Review of Scientific Instruments (36) 484-486
A vacuum‐jacketed metal calorimeter for determining heats of solution in aqueous HF was constructed. The reaction vessel was made of copper and was heavily gold plated. The calorimeter has a cooling constant of 0.6 cal‐deg−1‐min−1, approximately ¼ that of the air‐jacketed calorimeters most commonly used with HF. It reaches equilibrium within 10 min after turning off the heater current. Measurements...
Fluorometric study of the beryllium-morin system
M. H. Fletcher
1965, Analytical Chemistry (37) 550-557
Three principal beryllium-morin complexes, a (1 + 1) monomer, a (1 + 1) dimer, and a (1 + 2) complex are found and conditional equilibrium constants for their formation are evaluated. Approximate ionization constants, absorption spectra, and the relative fluorescence intensities for five ionic species of morin are also determined...

Two new species of Plistophoroa (Microsporidea) from North American fish with a synopsis of Microsporidea of freshwater and euryhaline fishes
R.E. Putz, G. L. Hoffman, C. E. Dunbar
1965, Journal of Protozoology (12) 228-236
Two new species of Microsporidea, Plistophora salmonae from steelhead and rainbow trout (Salmo gairdntri) and Plistophora crpedianar from gizzard shad (Dorosoma cepedianum) are described. Schizonts to spores of P. cepedianae were found at one time within the same cyst, while only sporonts and spores of P. salmonae were found within the cyst.An illustrated synopsis of the known Microsporidea of freshwater and...
