Management AdviceManagement considerations
The advice for 2009 is biennial and valid for 2009 and 2010 and is cited in the text table below (see: ICES. 2008. Report of the ICES Advisory Committee, 2008. ICES Advice, 2008. Book 9. 345 pp.)
|Porbeagle (Lamna nasus). ||All areas || |
Given the state of the stock, no targeted fishing for porbeagle should be permitted and bycatch should be limited and landings of porbeagle should not be allowed.
Porbeagles are particularly vulnerable to fishing mortality, because the population productivity is low (long-lived, slow-growing, high age-at-maturity, low fecundity, and a protracted gestation period) and they have an aggregating behaviour. Therefore, risk of depletion of reproductive potential is high. It is recommended that exploitation of this species should only be allowed when indicators and reference points for stock status and future harvest have been identified and a management strategy, including appropriate monitoring requirements has been decided upon and is implemented.
