Effects of Long-Term Exposures to Copper on Survival, Growth, and Reproduction of Brook Trout (Salvelinus fontinalis)Canadian Science Publishing - Tập 28 Số 5 - Trang 655-662 - 1971
James M. McKim, Duane A. Benoit
During a 22-month period, all developmental stages of the brook trout (Salvelinus fontinalis) were exposed to copper (Cu(II)) concentrations ranging from 32.5 to 1.9 μg/liter. The highest concentration decreased survival and growth in adult fish and reduced both number of viable eggs produced and hatchability. Survival, growth, and reproductive success of adults in copper concentrations f...... hiện toàn bộ
Effects of Mercury and Copper on the Olfactory Response in Rainbow Trout, Salmo gairdneriCanadian Science Publishing - Tập 33 Số 7 - Trang 1568-1573 - 1976
Toshiaki HARA, Y. M. C. Law, S. Macdonald
The effects of mercury and copper on the olfactory response of rainbow trout (Salmo gairdneri) were studied by perfusing HgCl2 and CuSO4 solutions through the olfactory organs while recording the olfactory bulbar electrical responses to the standard stimulant, L-serine.The olfactory response was depressed during exposure to mercury and copper.

Homing of Rainbow Trout to Inlet and Outlet Spawning Streams at Loon Lake, British ColumbiaCanadian Science Publishing - Tập 16 Số 5 - Trang 695-719 - 1959
C. C. Lindsey, T. G. Northcote, G. F. Hartman
A four year field study was conducted on rainbow trout (Salmo gairdneri) spawning in the inlet and outlet of Loon Lake. Young and adult trout were trapped and marked in both streams. About 5000 fish spawn in the outlet between mid-March and June; about 22,000 spawn in the inlet between late April and July. Outlet young either enter the lake by late summer or overwinter in the stream and e...... hiện toàn bộ
Theory of the Exploitation of Tidal Energy and Its Application to the Bay of FundyCanadian Science Publishing - Tập 26 Số 11 - Trang 2887-2957 - 1969
Gabriel Godin
Considerable progress has been made in the understanding of the concepts underlying the exploitation of tidal energy during the last 20 years; this progress has culminated in the actual construction of a tidal plant at the mouth of the Rance River near St. Malo, France. Since the Bay of Fundy is one of the largest reservoirs of tidal energy in the world, the theory of exploitation of tida...... hiện toàn bộ
Effect of Tidal Barriers Upon the M2 Tide in the Bay of FundyCanadian Science Publishing - Tập 26 Số 9 - Trang 2477-2492 - 1969
Kenneth B. Yuen
A model was constructed for the M2 tide in the Bay of Fundy, in which the two-dimensional hydrodynamical equations with quadratic friction were integrated in time. After calibration tests, in which the normal tide was reproduced, calculations were carried out to determine any changes from the normal configuration caused by the presence of tidal barriers in the vicinit...... hiện toàn bộ
So sánh hành vi cạnh tranh và ăn uống của cá hồi nuôi trong trại và cá hồi hoang dã trong bể nuôi Dịch bởi AI Canadian Science Publishing - Tập 25 Số 1 - Trang 1-14 - 1968
Owen C. Fenderson, W. Harry Everhart, Kenneth M. Muth
Khi cá hồi đại dương (Salmo salar) nuôi trong trại và cá hồi hoang dã cùng tuổi và kích cỡ được cho phép cạnh tranh cho vị trí xã hội và thức ăn trong bể nuôi, số lượng cá hồi nuôi đạt được vị trí thống trị gấp đôi so với cá hồi hoang dã. Các con cá hồi nuôi đạt vị trí thống trị cũng thể hiện sự hung hãn cao hơn so với các con cá hồi hoang dã thống trị, với tỷ lệ mổ cao hơn và biến thiên ...... hiện toàn bộ
