Resource summary

Impacts of Fishing on Benthic Communities
  1. Fishing using gear that has contact with the bottom causes physical disturbance e.g. set nets, trawls, bottom long lines etc.
    1. Natural physical disturbances (seasonal storms, tidal cycles, activities of burrowers etc.) impact organisms less as they are used to recovering from them
      1. Impacts depends on the nature of disturbances, frequency, scale and intensity, habitat stability and frequency of natural disturbance
        1. Fishing effort not homogenous. Some areas more heavily impacted than others. Fishermen often use same lines
          1. Resuspension of sediments - filter feeders can get clogged in feeding apparatus &be smothered
            1. Turnover of boulders or cobbles. Anything living on them can get destroyed
              1. Destruction of biogenic and rock reef habitats. Not just reefs.
