13.5 Threat: Invasive and other problematic species, genes and diseases
Texte intégral
13.5.1 Aquaculture
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
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.
13.5.3 Other
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)
9We 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.
