Impact of Seal Predation on Cod

The 2001 Report of the Eminent Panel on Seal Management concluded
that seals consume large amounts of fish throughout Atlantic Canada,
but there is much less evidence that this predation is having a major
impact on the recovery of most commercial fish stocks.

The findings of the report were not conclusive and many uncertainties
were acknowledged in providing realistic predictions. The Panel
acknowledged that gaining an understanding of the real impact of seals
on the recovery of cod is extremely complex and requires an in-depth
understanding of the marine ecosystem as well as additional research.
Findings highlighted in the report include:

The consumption of cod, and some other commercial species, by seals
in Divisions 2J3KL and 4RS3Pn is so large that a reduction in seal
predation could reasonably be expected to have a substantial effect on
the size of these stocks. However, the extent of this reduction would
have to be large in order for an impact to be observed.

There is not a simple, straight-line relationship between seal predation
and the state of fish populations. The interaction between seals,
groundfish and other species is complex and variable. For instance,
seals eat cod, but seals also eat other fish that prey on cod. Moreover,
other factors such as environmental changes and fishing levels must be
considered in trying to determine why cod stocks have not yet recovered.

The harp seal population has grown to the highest level recorded.
Coupled with the fact that the annual TAC has rarely been taken in full,
the panel expects a gradual increase in seal numbers if the current
management approach is maintained.

The current scientific knowledge is insufficient to determine the impact
of a seal cull on cod fisheries in the short, medium or long term. Science
and resource managers question the value of a cull in a fishery driven by
economic market conditions. More importantly, there is no way of
knowing how other predators and prey might respond to a decrease in
the seal population.

Current estimates of cod consumption by seals vary greatly from less
than one per cent to more than 20 per cent of diet, depending on the
type of seal researched, the time of year and location of the studies.
The panel concluded that more comprehensive research needs to be
done to more accurately estimate the amount of cod that seals are
consuming.
