Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

MANAGEMENT QUALITY

As calculated for 2011 data.

The score is ≥ 6.

Reference points unavailable. Stock assessed using surveys. Note MSC conditional criteria

As calculated for 2011 data.

The score is ≥ 6.

Mangers follow most scientific advice

As calculated for 2011 data.

The score is ≥ 6.

Harvesters follow regulations (Pottinger et. al, 2006). But see notes.

STOCK HEALTH:

As calculated for 2011 data.

The score is ≥ 6.

After 2005, landings are for stock; including areas with and without quotas (Pottinger et al., 2009) Therefore total landings not shown. But stock wide biomass stable

As calculated for 2011 data.

The score is ≥ 6.

Fishing morality not calculated. However yield (Catch per trip) stable (Pottinger et al., 2009)

DATA NOTES
  1. Quotas set using survey biomass, no formal analytical assessment of reference points. MSC Conditional criteria to develop reference points by Area. (Pottinger et al., 2006)
  2. Biomass is commercially exploitable and as whole weight (Pottinger et al., 2006)
  3. Biomass is for entire stock (Pottinger et al., 2006)
  4. After 2005, landings (as whole weight) are for entire stock; including areas with and without quotas (Pottinger et al., 2009) Therefore total landings not shown as they are not compatible to published quota.
