13.5 Threat: Invasive and other problematic species, genes and diseases

p. 677-680


Texte intégral

13.5.1 Aquaculture

Image

No evidence found (no assessment)

1We have captured no evidence for the following interventions:

  • Implement quarantine to avoid accidental introduction of disease, non-native or problem species
  • Implement regular inspections to avoid accidental introduction of disease or non-native or problem species
  • Import spat and/or eggs to aquaculture facilities rather than juveniles and adults to reduce the risk of introducing hitchhiking species
  • Prevent the attachment of biofouling organisms/species in aquaculture
  • Reduce and/or eradicate aquaculture escapees in the wild
  • Remove biofouling organisms/species in aquaculture
  • Source spat and juveniles from areas or hatcheries not infested with diseases or non-native or problematic species
  • Use native species instead of non-native species in aquaculture systems
  • Use sterile individuals in aquaculture systems using non-native species.

13.5.2 Shipping, transportation and anthropogenic structures

Image

No evidence found (no assessment)

2We have captured no evidence for the following interventions:

  • Clean anthropogenic platforms, structures or equipment
  • Clean the hull, anchor and chain of commercial and recreational vessels
  • Limit, cease or prohibit ballast water exchange in specific areas
  • Treat ballast water before exchange
  • Use antifouling coatings on the surfaces of vessels and anthropogenic structures.

Unknown effectiveness

●Remove or capture non-native, invasive or other problematic species

3One study examined the effects of removing or capturing non-native, invasive or other problematic species on subtidal benthic invertebrates. The study was in the South Atlantic Ocean (Brazil).

4COMMUNITY RESPONSE (0 STUDIES)

5POPULATION RESPONSE (1 STUDY)

6Cnidarian abundance (1 study): One replicated, controlled, before-and-after study in the southwest Atlantic found that, regardless of the method used, removing invasive corals reduced the cover of native zoanthids.

7Sponge abundance (1 study): One replicated, controlled, before-and-after study in the southwest Atlantic found that the effect of removing invasive corals on the cover of native sponges varied with the removal method used. Assessment: unknown effectiveness (effectiveness 40 %; certainty 23 %; harms 22 %).

No evidence found (no assessment)

8We have captured no evidence for the following interventions:

  • Limit, cease or prohibit the sale and/or transportation of commercial non-native species
  • Use biocides or other chemicals to control non-native, invasive or other problematic species
  • Use biological control to manage non-native, invasive or other problematic species populations
  • Use of non-native, invasive or other problematic species from populations established in the wild for recreational or commercial purposes.
