Approach |
| Eno et al. 2001 |
Badentarpet Bay, west
coast of Scotland |
Not given |
Soft mud |
Bending
and smothering of sea pens underneath pots; uprooting of some sea pens when
pots are dragged over bottom. |
Sea
pens recover from effects of pot dragging within 24-72 hr, re-assume upright
posture within 72-144 hr of pot removal, and re-root as long as “foot”
remains in contact with bottom. |
Diver
observations and experiments to assess effects on, and recovery of, sea pens
following dragging, uprooting, and smothering by lobster pots left on bottom
for 24 or 48 hr. |
| Eno et al. 2001 |
Greenale Pt., Wales,
and Lyme Bay,
southwest England |
14-20 m |
Varied – from bedrock to boulders to coarse sediment
– and interspersed. |
Soft
corals bent by pots, but spring back; pots leave tracks in bottom when
hauled; increased abundance of 4 species of sponges, an ascidian, and a
bryozoan in experimental plots after 4 wk, no changes in abundance of other
epibenthic species. |
|
Diver
observations and experiments to assess effects of 4 wk of simulated
commercial pot fishing on attached epifauna at two study sites. |
