What is disrupting fish habitat?

The federal Fisheries Act prohibits
"harmful alteration, disruption or
destruction of fish habitat". Where
there has been disruption of fish
habitat which results in prosecution,
to secure conviction must the Crown
prove actual harm to fish or is it
sufficient that there have been
negative even if temporary impact on
fish habitat?
The British Columbia Supreme
Court recently considered a
conviction appeal by the operators of
two gasoline -powered dredges which,
during the course of dredging a creek
bed, had disturbed the bottom of the
stream and displaced rocks. The trial
judge had convicted the dredge
operators on the basis that the Crown
need prove only a disruption of fish
habitat without the necessity of
proving that the disruption caused
actual harm to fish or the fish habitat.
While the appellate court
disagreed with the trial judge and
held that, for conviction, the
disruption must impair the value or
usefulness of the habitat, the court
upheld the conviction because the
evidence established that even a
temporary disruption will result in
such impairment. In coming to this
conclusion, the court referred to an
earlier case in which the court held:
"I do not think that harm to fish is
an element of the offence. What is
prohibited ... is the harmful
alteration, disruption, or
destruction of fish habitat, not the
alteration, disruption, or
destruction of fish habitat that
results in harm to fish. In my view
... the offence is established if the
Crown proves beyond a
reasonable doubt that the accused
interfered with the fish habitat in a
way that has impaired the value or
the usefulness of the habitat ...
thus, neither proof of actual harm
to fish nor the assumption of such
harm is necessary, as that fact is

not material".
However, in upholding the
conviction, the court accepted the
conclusion of the trial judge that for
conviction, there need be evidence
only of some impact on fish habitat
while the activity is ongoing and that
the impact need not be long term or
be shown to have a negative effect on
fish or fish production. The appellate
court considered the following expert
evidence sufficient for conviction:
"I take this testimony to be
definitive statement of opinion by
(the Crown expert) that if one
moves boulders around in a stream
bed that will have a negative
impact on the fish habitat because
it will negatively impact the fish's
opportunity to lie -up in areas of
reduced water velocity. (The
expert) clearly says that these
cover areas are vital to the fish's
survival and condition. Depriving
the fish of these cover areas by
disturbing larger objects in the
stream bed will clearly negatively
impact the fish's habitat".
The appellants' admission of
turning rocks over in the streambed in
preparation for the dredging
operation and entering into the stream
to organize the dredging operation
was sufficient basis for their
conviction on the offence of
disrupting fish habitat. Contravention
of this statutory prohibition occurs
even where the impact is only
temporary and no actual harm to fish
is established.0
