SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Scomber colias

SPECIES NAME(s)

Atlantic chub mackerel, Chub mackerel

A unique stock in the NE Atlantic is here assumed, in accordance to Zardoya et al. (2004), that recognizes a panmictic population with gene flow between the Mediterranean Sea and the Atlantic Ocean; however (Costa et al. 2011), basing their findings in parasites' analysis, ponder the existence of different stock units along the Eastern Atlantic.
Based on the complete and partial mitochondrial and nuclear DNA sequences (Infante et al, 2007; Catanese et al, 2010), the Atlantic chub mackerel Scomber colias is considered a distinct species of chub mackerel Scomber japonicus which is in turn distributed along the Pacific Ocean.

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.

OVERVIEW

  • This species is considered abundant in its distribution area.
Weaknesses
  • There is no scientific assessment and consequently, no reference points are defined.

  • An analytical assessment should be developed in short-term.

1.STOCK STATUS

STOCK ASSESSMENT

Despite the abundance and economic importance of Atlantic chub mackerel (Scombrus colias) throughout its habitat, knowledge about its biology and population dynamics is still scarce. There is no formal assessment. However several studies on age and growth have been developed in Portuguese coast (Martins 2007, Carvalho et al. 2002, Vasconcelos et al., 2011).

SCIENTIFIC ADVICE

There is no scientific advice for this fishery.

Reference Points

There are no reference points defined.

CURRENT STATUS

The Atlantic chub mackerel was the most abundant species fished in PELAGOS13 survey that took place in Portuguese and Gulf of Cádiz waters (ICES, 2013). Since 2005, landings have been variable between 15,000 and 33,000 tons, well above the long-time series average (around 11,000 tons) (FAO, 2013).

2.MANAGEMENT QUALITY

MANAGEMENT

In Portugal the purse-seine fishery can be directed to sardine, Atlantic chub mackerel, bogue, anchovy and horse mackerel. Currently, purse-seiners in Portuguese waters have a length of about 20 m; an engine horsepower between 100 and 500 HP and use a minimum mesh size of 16 mm (ICES, 2013). In the Azores, artisanal fleet includes this species as one of its main target but is considered as bycatch in the longline demersal fishery operating offshore areas and is also used as bait for the tuna longline and handline fisheries (Carvalho et al. 2002).

COMPLIANCE

Spanish mackerel is only fished by Spain and Portugal (ICES, 2011). Until some years ago, this species was in many occasions “slipping” or discarded because there was no demand for this species (Wise et al., 2005).

Recently has been developing a public campaign to promote the Atlantic chub mackerel consumption (DOCAPESCA, 2013). In 2005, chub mackerel represented 13% of the total species landed in weight by the Portuguese purse seine fleet (IBERMIX, 2007).

Last updated on 15 October 2013

In Portugal the purse-seine fishery can be directed to sardine, Atlantic chub mackerel, bogue, anchovy and horse mackerel. It is allowed a by-catch of other species up to a maximum of 20% in weight per trip (IBERMIX, 2007).
