Duration of protection against Aeromonas salmonicida brook trout immunostimulated with glucan or chitosan by injection or immersion Duration of protection against Aeromonas salmonicida brook trout immunostimulated with glucan or chitosan by injection or immersion
Brook trout (Salvelinus fontinalis) were given the immunostimulants glucan or chitosan by single injections or by a 30‐min immersion to induce protection against the fish disease furunculosis. At 1, 2, 3, 7, 14, 21, and 28 d after immunostimulation, sublots from these groups were challenged by a 1‐min bath exposure to a 48‐h culture of Aeromonas salmonicida. All four groups showed high...

Effect of subatmospheric pressure on the performance of an automated packed-column nitrogen desorption system Effect of subatmospheric pressure on the performance of an automated packed-column nitrogen desorption system
A portable vacuum degasser was developed to satisfy seasonal hatchery pretreatment needs. Dissolved-gas pressures in water exiting a packed column were regulated automatically with a unique feedback control loop incorporating a gasometer, pressure transducer, electronic (PID) controller and an electrically actuated pump discharge valve. The flow capacity of the system was 160 l/min with...

History of early diet development in fish culture, 1000 B.C. to A.D. 1955 History of early diet development in fish culture, 1000 B.C. to A.D. 1955
This paper traces the observations and speculations of early fish culturists as they sought to define the feeds necessary to keep hatchery fish alive. Although prescientific ideas about feeding fish existed in Egypt and China over three millennia ago, it was not until the 1700s that scientific studies of feeding and digestion by fish were documented. Aside from several books that...

Environmental contaminants in redheads wintering in coastal Louisiana and Texas Environmental contaminants in redheads wintering in coastal Louisiana and Texas
Whole body and liver analyses indicated that wintering redheads (Aythya americana; n = 70) in coastal Louisiana (one site) and Texas (two sites) were relatively free of contamination with common trace elements, organochlorines, and hydrocarbons. Most trace elements, including As, Cr, Hg, Mg, Mn, Ni, Pb, Se, Sr, and Zn, were within background concentrations in livers; levels of B, Cd, Cu...

Trace elements in canvasbacks (Aythya valisineria) wintering in Louisiana, USA, 1987-1988 Trace elements in canvasbacks (Aythya valisineria) wintering in Louisiana, USA, 1987-1988
We determined trace element concentrations in livers of canvasbacks (Aythya valisineria) collected at Catahoula Lake and the Mississippi River Delta, Louisiana during, the winter of 1987–1988. Forty percent of canvasbacks wintering at Lake Catahoula had elevated concentrations of lead (>6·7 μg g−1 dry weight) in the liver; 33% had concentrations consistent with lead intoxication (>26·7...
