LONG ROUGH DAB
Hippoglossoides platessoides
Publication of Advice: 7 June 2024. Published by Marine and Freshwater Research Institute.
Advice
Long rough dab is only caught as bycatch, and landings are very low. Therefore, MFRI does not advise a TAC for the 2024/2025 fishing year and will not provide catch advice until substantial changes occur in biomass index and/or exploitation.
Stock development
MFRI cannot assess the stock and exploitation status relative to maximum sustainable yield (MSY) and precautionary approach (PA) reference points because the reference points are undefined.
Long rough dab. Catch by gear type, recruitment (juvenile <10 cm) and biomass (>30 cm). Shaded areas and error bars show 95% confidence intervals.
Other information
IS-SMB covers the distributional area of long rough dab in Icelandic waters. The survey indices indicate that the stock declined rapidly in 2003–2008, over a period where landed catch was well below the set TAC. It is therefore unlikely that the decline in the stock was solely due to fishing. Stock size is close to an all-time low, but recruitment has been high in recent years, which might lead to an increase in stock size over the next few years. It is likely that landed catch does not reflect the total catch.
