harbor. Large temperature fluctuations were linked in
informants’ minds to increased unpredictability, which
in turn impacts at-sea operations. Small-scale fishers
noted a decrease in the number of fishing trips in one
fishing year due to bad weather and storm events that
force the boats to stay in the harbor. As an example, one
longline fisher mentioned that they used to be normal to
go on fifteen fishing trips in thirty days in the months of
December and January; however, due to increasing stor-
miness the number of fishing trips has decreased to ten
per month.
Though having to avoid storms by either staying in
‘he harbor or sheltering in the fjord can lead to tempor-
ary loss of income for both large- and small-scale fish-
eries, there are other risks associated with storminess. In
moderately stormy weather a captain may make the
decision to go out to sea, even in waves 4 to 5 m high.
It was noted that the catch decreases during bad weather
because fish can be lost off the lines. Damage to fishing
ınfrastructure can also occur in harbor during a storm.
There have been incidents where the harbor areas were
ooded due to a combination of a low-pressure system
and especially high spring tides, causing damage to port
electricity and other infrastructure that, in turn, affected
provisions for necessary facilities and services for boats.
In sea pen aquaculture, damage due to icing during
storms creates a financial risk for the aquaculture com-
panies. In one recent case, a heavy storm caused icy
buildup around the pens that damaged the nets. In
another incident, a storm caused an electricity outage
on a land-based aquaculture site, which led to a high fish
mortality rate due to impeded nutrient circulation.
Furthermore, as one informant emphasized, a failure
of the equipment during an extreme weather event or
storm can also have adverse effects on the company’s
public image if the failure causes an economic or envir-
onmental risk. An aquaculture stakeholder noted that
the equipment used for aquaculture pens can
surprisingly withstand quite bad weather conditions.
At the same time, another noted that decreased quality
of fish was observed in pens located farther outside the
Hord in a site more exposed to extreme weather condi-
ions. Furthermore, if storms become more intense and
Irequent, staff might be sent out to repair the damage to
ens during unfavorable weather conditions, which
increases the risk of personal injuries at sea,
Indeed, for all operations at sea, a major concern is
he safety of the crew. All informants agreed that storm-
zelated accidents at sea have decreased over time due to
he availability of improved equipment and a well-
developed weather forecasting system. Furthermore,
he requirement of all those working at sea to attend
safety school greatly minimizes the risk to maritime
workers. Good forecasting and safety training, together
with the increased willingness of Icelandic fishers to
contact the Coast Guard in risk situations, has led to
a decreasing number of rescue missions. However, the
Coast Guard noted that assistance missions have
.ncreased over time, which is partially due to storm-
celated problems but is also due to other issues such as
ired sailors who run aground or failed equipment. It
was also mentioned in the interviews that decisions to go
aut in stormy weather are often made because of (in the
wording of informants) greed and competition among
Aishing crews.
External threats and problems
Related to the general areas of impacts listed above,
informants identified several threats and problems in
äsheries and aquaculture that have connections to
storm events. Informants agreed that the fact that storms
are becoming more intense and frequent is only one part
of climate change that should not be considered by itself
but as part of a combination of climate-related threats.
Many informants were concerned about the compound
effects of rising sea temperature and fish stock
