MARINE BIOLOGICAL STATIONS OF CANADA. 
The three Biological Stations at St. Andrews, N.B., at Go Home, 
Georgian Bay, Ont., and at Departure Bay, near Nanaimo, B.C., have 
continued their active operations under the Department of Marine and 
Fisheries during the past year. 
The fine and commodious permanent buildings in the estuary of 
the St. Croix River, Passamaquoddy Bay, N.B., about 2 miles out of 
St. Andrews, proved admirably adapted to the purpose of marine 
biological and fishery investigation, and, during the season of 1909, 
Professors and University Assistants from the various Canadian Colleges 
have pursued important investigations, all having more or less direct 
bearing upon the fisheries of the Dominion. Professor Penhallow of 
McGill University, Montreal, was again Director of the Station, and 
under authority from the Biological Board he supervised the researches 
carried on by the staff. The problems taken up included the following:— 
Experiments with traps made with wide slats, to decide if lobsters 
under 9 or 84 inches escape if captured in such traps.—Retaining lobsters 
in enclosure to decide growth in course of season.—Rearing experiments 
on Dr. Mead’s plan.—Retaining live squid or cuttle fish in floating cars 
for bait.—How long will they live when fed and thus confined?—Con- 
tinued Plankton work.—Breeding for Mollusks.—Do shad occur in 
herring weirs?—Breeding of smelts, eggs and young.—Continuation of 
studies on food of fishes.—Algal studies, Diatoms and lowly plant life.— 
Information as to St. Croix salmon, ascent, and descent of smelts, &c. 
—Land-locked salmon and other fish in Chamcook Lakes.—Food of 
herring off Grand Manan, large shrimp-like forms, &c.—Experiments in 
marking fish planned last year; fish to be taken by Station Staff and 
liberated after marking.—Faunistic work continued.—Food of Shad 
samples from up the Bay of Fundy.—Marine Algae of the Bay. 
Several members of the Statf pursued additional researches, and 
one of them, Professor E. W. MacBride, spent some time on Prince 
Edward Island, completing the oyster-culture experiments, which have 
for several seasons been conducted at Baltic River in the province 
named. The Provincial Government had kindly granted a reserved 
area on Baltic River for scientific oyster experiments by the Staff of the 
Station. Much of the work done during the last three or four years is 
now sufficiently advanced to enable printed reports to be issued, and 
the following list of valuable reports and memoirs, illustrated by over 
twenty plates, will appear shortly as Volume III of “Contributions to 
Canadian Biology.”
