OYSTER PROPAGATION IN P.E.I. 65 
SESSIONAL PAPER No. 38a 
At the head of Upper Bideford, August 6, low water was 1019-5 at 74° F. Four 
samplings, each of 20 quarts, along its course to Trout river, yielded seven fry of 160 
microns, and a few at 100. 
Between Trout river and the Narrows, August 6, in water of 1019.5 at 72° F., large 
fry were present at the rate of one per 30 quarts. August 17, fry were fourid of sizes 
120, 180 to 260, 360 to 380 microns, at the rate of one per 60 feet vertical, which means 
that in water 30 feet deep, ten hauls from bottom to top would yield five large fry. 
In the section off south end of Lennox island, August 6, water was 1020 at 70° F., 
and only one large fry and a few small ones appeared. On August 17, 1019 at 70° F., 
three samples gave twelve fry from 160 to 400 microns, most being 240 microns. 
In the section along Bird island, August 6, only few fry present, and less than 
120 microns in size. On August 17, water sample 1020 at 70° F., gave one fry of 200 
microns. 
Central bay, adjacent to Bideford river, August 6, 1021 at 70° F., fry less than 
110 microns. August 17, near low point, one fry 180 microns, one 240 microns. 
GRAND RIVER. 
From the bridge to the ferry is a distance of 4 miles, and from the ferry to 
Charles point is 3 miles. The latter section, 2 miles wide, is more a cove than a river. 
From the bridge to Southwest creek is nearly a mile, thence to Cross creek nearly two, 
and thence to the ferry is a mile and a half. About half a mile below the ferry at 
Black point the river empties into its cove. 
Section below the bridge, August 6, flow, 1018 at 72 F.; August 14, ebb, 1018-5 
at 74° F. Vertical samples gave one fry per 20 feet, sizes 120, 160, 320, 360 microns 
nearly equally abundant. August 20, flow, successively 1018 at 66 F. and 68 4°, 1017 
at 67 F., and farthest from bridge 1019 at 68 F.; very little hut sand in four samples. 
Samples on higher water gave one per 40 feet vertical, one per 10 quarts, four per 
minute towing, 80 to 200 microns. August 25, strong ebb, one fry per 6 feet of 
towing, from 120 to 320 microns, majority 240 microns. Towing one minute with 
large No. 12 net, gave seventy fry, 160 to 340 microns, with maxima at 240 and 320 
microns; small fry escape through this net. 
Section below Southwest creek, August 14, 1019-5 at 71° F., fry one per 2 feet 
vertical; farther down, one per 6 feet, ranging from 200 microns to smaller, most are 
below 160 mu.! Half of oysters dredged are still filled with spawn. August 20, 1018.5 
at 68 F., early flood, few fry; but when near high, 1019-5 at 68 F., fry are abundant, 
one per 6 feet vertical, one per 5 quarts, thirty per minute towing, ranging from 70 
mu to 280 mu, mostly below 100 mu. Farther down, 1019-5 at 68 F., one fry per 6 
feet vertical, one per ten quarts, twelve per minute, 90 to 860 mu. August 21, twelve 
samples, 1018-5 at 70 F., near high, gave one to 40 quarts, up to nearly one per quart, 
from 9 to 166 per minute, from one in 4 feet vertical, up to one per foot. Sizes run 
from 80 to 320 mu with four-fifths of them below 110 mu, and some at 200, 240, and 
320 mu. August 25, half ebb, 1020 at 70 F., twenty quarts dipped, give from 9 to 33 
_ fry, also at low 1019 at 74 F., got one fry per 2 feet vertical, and 34 per 160 feet of 
towing; sizes, 80 to 320 mu, majority below 120 mu, several at 180, 240, and 280 mu. 
August 28, 1019-5 at 68 F. flow; one fry in 8 to 15 feet vertical, eleven in 1 minute’s 
tow; sizes, 90 to 380 mu, with groups at 100, 150, 280, 320, 360 mu. 
Section above Cross creek, August 14, 1018-5 at 72 F. Oysters dredged here have 
all spawned, fry abundant, one per 2 feet vertical, ranging from 100 to 200 mu, and 
a few at 360 mu. Majority are 160 mu, perhaps ten days old. August 20, water low 
flow, 1018 at 68° F., few fry until near high, 1019 at 70° F. when fry are one per 40 
feet vertical, one per 5 quarts and fifteen per minute towing, and of sizes 80 to 280 
1 The name of the Greek symbol for ‘‘ microns,” is “ mu.”
