Stock status

1 of 5
Very low risk

Swordfish in the Indian Ocean has been scored a very low risk.  The ratio of the current (2013) biomass to that needed to produce the maximum sustainable yield (MSY) was 3.10, indicating the population is not overfished. Fishing mortality rates (2013) were below FMSY levels (0.34) and therefore the population is not undergoing overfishing. Current fishing mortality is not expected to reduce the population over the next decade {IOTC 2016}.

Management

3 of 5
Moderate risk

The management of swordfish in the Indian Ocean has been scored a moderate risk. Current management measures for the swordfish in the Indian Ocean is considered sufficient. However, there are concerns with regional depletion in the southwestern Indian Ocean and calls for specific management measures in that region have not been addressed.

Bycatch

3 of 5
Moderate risk

The bycatch in the swordfish Indian Ocean gillnet fishery has been scored a high risk. This is because gillnets capture a number of bycatch species, including sea turtles, sharks and other fish but there are some mitigation measures in place.

Habitat

1 of 5
Very low risk

The seabed effects of the fishery are scored a very low risk. This is because gillnets fish at the surface and do not come in contact with bottom habitats.
