98. A Fisherman informing me that the Fish were apt to die in the
Well-boats, it occurred to me that it might, in a good measure, be
remedied, by fixing upright a Board of a proper Breadth at the Outside
of the Boat, as long as the Well is deep, on that side of the Well
which is next to the Stern, and opening at an Angle of about 45 Degrees
towards the Head; which, by checking the Course of the Stream of
the River near the Boat, will raise the Water a little, and thereby
cause it to run into the Well on that Side, and out on the other Side
of the Boat; and the Run of the Water thro’ the Well, will be more
accelerated, if a like Board is fixed in the same manner on the other
side of the Boat at the Side of the Well next to the Head of the Boat,
but opening towards the Stern at an Angle of 45 Degrees, by which means
the Water will be lowered on this, as much as it is raised on the
other Side of the Boat.----Another Means to have a brisker Current of
Water thro’ the Well, would be to moor the Boat in a fixed Position
across the Stream when it can conveniently be done. I am informed that
there are Passages from Head to Stern, for the Water to pass freely
thro’ the Fish-Well of some Vessels. We see, from the Event of the
above Experiments, the Importance of frequently changing the Water in
the Fish-Well of Ships, especially when there are many Fishes in it.
Hence also we see how salutary it is to Fish, to have the Surface of
the Water agitated into Waves by Winds, whereby Plenty of fresh Air
enters, and is blended with the Water.
