Fish and people

This fish is caught as part of a targeted fishery. However, official food and agriculture records indicate there are no separate commercial landings reported specifically for this species. Instead, any catches are grouped together with other members of the same genus in the official statistics. Despite this lack of separate tracking, conservation groups note that fishers actively target it.

Status and threats

The exact conservation status of this species is not provided in the available text. While it is noted as a targeted fishery, the lack of separate catch data makes it difficult to assess population trends.
