Capelin. Catches, acoustic index for immatures from autumn surveys, and SSB at spawning time (with 90% confidence). Estimate of stock size for 2025 (dot) is based on projections.

Basis of the advice and reference points*

Prognosis

Capelin. Assumptions made for the interim year and in the forecast.

Capelin. Projection of SSB (tonnes) based on adopted harvest control rule.

Quality of the Assessment

The acoustic survey is considered to have covered the distribution area of the stock. The survey estimate had low coefficient of variation (CV=0.25) as the capelin was relatively evenly distributed.

There is uncertainty related to the calibration of one of the vessels participating in the survey that may affect the assessment results.

Other information

The autumn measurement on mature capelin is lower than the immature capelin estimate from the autumn measurements in 2023 indicated.

This advice will be revised based on results of acoustic measurements of the fishable stock in early next year.

Advice, TAC and Catch

Capelin. Recommended TAC, national TAC, and catches.
