Assessed
Data

Time series of fishing effort, i.e. number of hauls and catch (kg) from 2000 to 2020 from logbook records, annually aggregated length frequency data from 2011 to 2020, acoustic biomass indices from 2004 to 2018, and age composition data from the catch of 2017.

Type:  Others
CASAL

Integrated stock assessment.
Results

There is a high probability (76%) that the stock was not overfished and no overfishing was taking place in 2020.
Sci Advice

The exploitation on Walter’s Shoal Ridge and the larger Long Walter’s Shoal Ridge was well within sustainability limits while the exploitation in the Southwest Indian Ridge is too close to limit harvest rates (MSY).
