2. HIGH RISK GHOST
FISHING GEAR
2.1 HOOKS AND LINES

include different types and scales of
fishing gear, that span from a single
hook to lengthy longlines with
thousands of hooks. Hand lines
are relatively low risk in terms of
impact, but long lines in particular
can have significant impact if lost.
They also vary according to the
depth they operate, and whether
they are anchored, left to drift or
even towed. In most cases, these
are passive fishing gear that may
be baited to attract animals to be
caught. Be it an individual handline
or baited longline it is possible
for them to get lost or discarded.
As they can be quite cheap, they
often are discarded if they get
entangled or damaged. Also, in the
case of longlines, they are deployed
in extensive ocean areas, can be
many kilometers in length, and are
susceptible to being cut apart by

cruising ships or even competing
fishers. Even though longlines can
span lengthy distances the impact
they can generate when lost is less
than other fishing gear, especially
if they are deployed away from
the surface. But if baited, hooks
are more likely to keep catching
fish and other species, and this
can generate a feedback loop in
which a bigger fish can prey upon
the already baited fish. Hooks are
attached to the longline through a
mainline rope that is made from
plastic-derived materials, which - if
it is close to the surface - can harm
birds or other animals that might
get entangled. Sea turtles can also
be trapped on baited hooks, but
the invention of a curled turtle-safe
hook mitigates this impact. See
figures 8 and 9.
