The Plenary Report summarises biological, fishery, stock assessment and stock status information for 80 species or species groups, each of which is split into 1-10 stocks. The Plenary takes into account the most recent data and analyses available to Fisheries Assessment Working Groups (FAWGs) and the Fisheries Assessment Plenary and also incorporates relevant analyses undertaken in previous years.

Title: Plenary (EMA_FINAL 08)
EMA_FINAL 08.pdf (192.5 kb)

Little is known about the status of blue mackerel stocks and no estimates of current and reference

biomass, or yield, are available for any blue mackerel area. It is not known if recent catch levels are

sustainable or at levels that will allow the stocks to move towards a size that will support the MSY.

EMA 1

For EMA 1, the stability of the age composition data and the large number of age classes that comprise

the catches suggests that blue mackerel may be capable of sustaining current commercial fishing

mortality at least in the short term.

Little is known about the status of blue mackerel stocks and no estimates of current and reference biomass, or yield, are available for any blue mackerel area. It is not known if recent catch levels are sustainable or at levels that will allow the stocks to move towards a size that will support the MSY.

EMA 1
For EMA 1, the stability of the age composition data and the large number of age classes that comprise the catches suggests that blue mackerel may be capable of sustaining current commercial fishing mortality, at least in the short-term.

EMA 7
The broad spread of age classes seen in the catch from the trawl fishery is not consistent with the large decline in CPUE from 1999 to 2005. The Working Group agreed that it was is premature to make conclusions about trends in abundance based on the CPUE indices, due to the significant area/year interactions in the analysis.
