SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Trachurus murphyi

SPECIES NAME(s)

Chilean jack mackerel

COMMON NAMES

Jurel (Spanish)

Chilean jack mackerel is widespread throughout the South Pacific and the stock structure is not clear. Research based on genetic and otolith analysis supports the existence of a single population (SPRFMO, 2013a,b), as well as a recent analysis using a biophysical model, that indicates high dispersion range and spatial overlap of modeled recruitments, which supports the existence of a single panmictic population in the SE Pacific (SPRFMO 2016). A single assessment unit is here considered given the uncertainties.

Of the existing five management units, the Ecuadorian (GdE 2014), the Peruvian (El Peruano 2017) and the high seas fisheries (the SPRFMO Convention area; all pelagic trawlers) are exclusively for direct human consumption; Chilean fisheries operating (the northern, XV-II regions and the central-southern Chilean, III-X regions) are mainly used for fishmeal (Quiroz 2017).


ANALYSIS

Strengths
  • Since 2010, the South Pacific Regional Fisheries Management Organization conducts a joint jack mackerel assessment and since 2013, catch limits are agreed for the assessment unit area and for the Convention area, in accordance with scientific recommendations.
  • A recovery plan (harvest control rule) has been adopted in 2014.
  • The assessment model continues to be revised and improved. Data, information, and decisions from all fishing countries are integrated into the assessment process.
  • Fishing mortality has been decreasing and is well below the target level.
  • The spawning stock increased comparing to last years and is now above the MSY level. 
  • Joint efforts are in place to control illegal, unreported and unregulated fishing – list of IUU vessels, a Commission Vessel Monitoring System is being implemented and work is in progress to set up an SPRFMO observer program.
  • Bycatch rates of commercial species appear to be low in most fleets, but comprehensive lists of bycatch species are not known to be produced.
  • No interactions of the fishery with protected species are reported but it is unclear if reporting is adequate.
  • A Chilean management plan was recently published for the fishery but does not include a harvest control, which is pointed out by the SPRFMO.
Weaknesses
  • Although efforts have continued to elucidate the stock structure, conclusive evidence is not available and further research is required, e.g. tagging experiments. There are also uncertainties in the assessment related to natural mortality, input data quality, and growth.
  • The Ecuadorian scientific recommendation or defined TAC for the national fishery has not been available in the last years. 
  • Reference points are provisional and uncertainties were raised by the SPRFMO Scientific Committee about the discontinuities in the fishing mortality to be applied under the harvest control rule and the constraints in the interannual TAC variability.
  • Important environmental events, such as the strong 2015-2016 El Niño, influence the spatial distribution of jack mackerel, but effects on the overall population productivity are unclear.

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.

1.STOCK STATUS

STOCK ASSESSMENT

Last updated on 2 July 2019

Since 2010, a joint jack mackerel stock assessment has been conducted, including fisheries independent and dependent data from each fishing country in a statistical catch-at-age model performed by the South Pacific Regional Fisheries Management Organization (SPRFMO)’s Scientific Committee (SC). The models run consider the two working hypotheses on stock structure: 1) two separate stocks, Peruvian/northern stock and Chilean/southern stock that straddle the high seas; 2) a single shared stock that straddles the high seas. Hypothesis 2 has been used as the basis for the advice, as it provides a more precautionary biomass estimate (SPRFMO 2017)(SPRFMO 2018). Benchmarks are conducted every two years, with a "full" assessment having been performed in 2018. Uncertainties raised in the 2018 report relate to the stock structure, natural mortality, input data quality, and growth (SPRFMO 2018)

SCIENTIFIC ADVICE

Last updated on 2 July 2019

The Scientific Committee (SC) of the SPRFMO meets yearly. Scientific recommendations combine data and decisions of experts of each fishing country, based on the joint assessment results. From 2011-2017, two advised Total Allowable Catch (TAC) have been proposed: one for the whole assessment unit (relative to stock structure not yet defined) and another for the SPRFMO Convention area (where members and non-contracting parties operate; localized in the high seas) (SPRFMO 2017).

For 2019, only the advice for the whole assessment unit was provided. The SC preferred the "one-stock model", as in previous years. Considering the overestimation trend in the stock size and underestimation of the species' growth and that the assessment is on the "second tier" of the rebuilding plan in place (at >80% of BMSY), 591,000 tonnes are the advised catches for the entire assessment unit (SPRFMO 2018).

In 2016, the SC recommended that age validation work continue to be pursued, as analysis and validation of juvenile growth is a key information gap; for this a tagging experiment was suggested. The SC also recommended supporting the Fishery dependent acoustic initiative and suggested the design of a joint synoptic survey using data collected along the normal tracks of properly equipped and calibrated fishing vessels (SPRFMO 2016). Exchange of samples among countries are also recommended by the SC to determine differences in growth curves and ageing techniques. Sampling of data was agreed to be improved to help to determine the stock structure (SPRFMO 2017). In 2018, the SC provided recommendations regarding the design of the harvest control rule and raised the need to review the management plan, which is already foreseen in the SC multiannual workplan. On the other hand, based on the information brought by the EU, members are encouraged to implement self-sampling programmes, which can be a valuable complement to the observer programme, as well explore the use of electronic monitoring as verification tools (SPRFMO 2018)(SPRFMO 2018)

The Scientific Committee for the Pelagic jack mackerel fishery (Comité Científico de Pesquería Pelágica de Jurel, CCT-J), as in the previous year, did not agree with the results presented by the SPRFMO Scientific Committee (SC) given the uncertainties. Only two members supported the model chosen by SPRFMO (1.5), with the majority (5) of members preferring model 1.4. According to the Chilean Fisheries Law that requires a range, the precautionary TAC with an F<FMSY, is therefore advised to be between 476,800 and 596,000 tonnes (CCT-J 2018), above last year's recommendation. 

The Undersecretariat of Fisheries and Aquaculture (Subsecretaría de Pesca y Acuicultura, SUBPESCA), on the other hand, according to the SPRFMO decision and quota share for Chile (65% of the TAC for the assessment unit during 2018-2021), states that the Chilean TAC is recommended at 381,572 tonnes (65% of 591,000 tonnes)(SUBPESCA 2018), below CCT-J's recommendation.

CURRENT STATUS

Last updated on 2 July 2019

Reference points remain as in the last year: BMSY is provisionally fixed at 5,500,000 tonnes; FMSY and SSBMSY are dynamic and estimated annually, at 0.13 and 4,514,000 tonnes respectively. The estimated increase in biomass to 90% of the interim BMSY, resulted from the fishing mortality rates decreasing in the past three years to 0.09 in 2018 and well below FMSY, along with the slight recruitment improvement. Catches are preliminarily reported at 472,966 tonnes in 2018 for the whole assessment unit, rising in the last four years (SPRFMO 2018).

Environmental conditions (e.g., strong El Niño 2015-2016) likely affect jack mackerel's distribution and thus age-specific vulnerability to surveys and fisheries. This may have affected the Chilean northern acoustic survey and those conducted in Peruvian waters. The effect of such environmental changes in the overall population productivity is unclear (SPRFMO 2016; SPRFMO 2016)(Quiroz 2017). Currently "several members (of the SC) noted concerns about the suitability of the El Niño index used in the analysis" (SPRFMO 2018). A Habitat Monitoring working group was created, to assess the influence of the environmental conditions and habitat on the assessment unit (SPRFMO 2018).

According to the voting results of the Chilean technical-scientific committee (that chose model 1.4 contrarily to the SPRFMO decision), the assessment unit is considered as overexploited (SSB2018/SSBMSY=0.712), and overfishing is not occurring (F2018/FMSY=0.441). Reference points are defined differently to the SPRFMO: SSBMSY = 7,074,000 tonnes, Blim = 1,768,500 (25% of SSBMSY) and FMSY = 0.195 (CCT-J 2018)(SUBPESCA 2018)

2.MANAGEMENT QUALITY

MANAGEMENT

Last updated on 2 July 2019

Management of jack mackerel in the high seas is officially organized through the South Pacific Regional Fisheries Management Organization (SPRFMO) since 2013 (SPRFMO, 2015d). Currently, an overall TAC is agreed by the SPRFMO for the whole assessment unit, with part of that bound under a Conservation and Management Measure (CMM) applying to the international waters under SPRFMO’s jurisdiction and also to Chilean national waters due to its express consent since 2014 (SPRFMO, 2015a)(MFA 2019). Catch limits can be transferred among countries and catch allocations transferred in 2018 are available here.

A preliminary proposal of a Harvest Control Rule (HCR) was submitted by (Canales 2014) and in the same year (Hintzen et al. 2014) presented evaluations of the HCR proposed. A rebuilding plan was adopted and is being currently used to establish the TAC (Scarcella et al. 2019) but uncertainties were raised in the last Scientific Committee report about the discontinuities in the F to be applied and the constraints in the interannual TAC variability. The discussion presented by (Hintzen et al. 2014) should be revisited to further improve the HCR in place (SPRFMO 2018).

In line with the Scientific Committee’s recommendation (SPRFMO 2018), overall catches for the entire assessment unit were agreed to not exceed 591,000 tonnes in 2019; the TAC for the Convention area is defined at 531,061 tonnes (SPRFMO 2019). Catch percentages are established for each member/CNCP and apply during 2018-2021. Countries submit their reports according to specific guidelines. Until an Observer program is officially implemented, countries have to "ensure a minimum of 10% scientific observer coverage of trips for trawlers and purse seiners flying their flag and ensure that such observers collect and report data as described in CMM 02-2018 (Data Standards)" (SPRFMO 2019).

Chile has been managing its fishery with quotas since 1999, and collaborating with SPRFMO since before its official date of establishment in 2012 (SPRFMO n.d.)

In line with the SUBPESCA report (SUBPESCA 2018) and the quota share defined by the SPRFMO but contrarily to the advised by the CCT-J (more details in the Scientific Advice section), the overall Chilean TAC for 2019 was officially set at 381,572 tonnes and the partial quota for the industrial fishery operating in the northern area (XV-II regions) has been increasing and was defined at 53,236 tonnes (MEFT 2018). As since 2014, the Chilean Ministry of Foreign Affairs – Division of Environment and Maritime Affairs consents that the Conservation and Management Measure (CMM) established by the SPRFMO (SPRFMO 2019) extends to Chilean waters (MFA 2019)​. Chile summed up around 76,000 of quota transfers in 2018, from different countries.

A management plan was officially approved in December 2017, aiming to "recover and maintain the biological Jack mackerel fishery, economically, socially and ecologically at sustainable levels", in line with the Chilean General Fisheries and Aquaculture law. Based on the precautionary approach, goals, and milestones in each dimension are strategically defined, as well as indicators and correspondent management measures and actions (SUBPESCA 2017). The discarding reduction plan specific for the fishery was officially published in 2019 (MEFT 2019)(SUBPESCA 2019). The fishery is deeply described. Catch composition, interactions with the ecosystem and trophic relationships are identified as priorities to be studied (SUBPESCA 2017).

COMPLIANCE

Last updated on 2 July 2019

Catches have decreased significantly in recent years and have generally been under the set TAC. The preliminary value for 2018 global catches (used for assessment purposes) is at 472,966 tonnes (SPRFMO 2018), below the TAC set for the year at 576,000 tonnes (SPRFMO 2018).

Proposals of the European Commission (EC) were used by the SPRFMO to diminish IUU fishing (EC, 2013). The Commission Vessel Monitoring Systems (VMS) is being implemented (SPRFMO 2017) and work is in progress to set up an SPRFMO observer program (SPRFMO 2016)(SPRFMO 2017)(SPRFMO 2018). There are some instances of non-compliance with SPRFMO’s Conservation and Management Measures, particularly as to timely reporting. Ecuador and the Russian Federation are mentioned due to distinct reasons, explained in detail in the report (SPRFMO 2019).

A list of vessels conducting Illegal, unreported and unregulated (IUU) activities was adopted at the 3rd SPRFMO Commission meeting in 2015 and has been published since then. Inclusion in the list refers in all cases to fishing in the SPRFMO Convention Area without authorization (SPRFMO, 2016a; SPRFMO 2017)(SPRFMO 2019)

The jack mackerel fishery management plan established two specific compliance goals to be monitored in 2017: quotas and access to the fishery (SUBPESCA 2017)

Within the Northern management unit (MU), Chilean catches (10,896 t) are below the partial quota assigned (51,884 t). The country allocated quotas from the SPRFMO members in the amount of ~76,000 t (SPRFMO 2018), which summed to the overall TAC (at 371,887 t for 2018 (from (MEFT 2018)) results in 447,887 t. Therefore, total Chilean catches at 402,528 t (391,632 t for the Central-southern MU and 10,896 t for the Northern MU) did not overpass what was allowed.

In January 2019, a new law that strengthens the inspection body (SERNAPESCA) was published (MEFT 2019)​.

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
Other Species

Last updated on 28 June 2018

The fishery for jack mackerel is generally a monospecific fishery. In the offshore fishery the catch consists for 90 – 98% of jack mackerel, with minor by-catches of chub mackerel (Scomber japonicus) and Southern rays bream (Brama australis) (SPRFMO, 2015c).

An Assessment of the Impact of Fishing on Non-target, Associated or Dependent Species is being undertaken for all fishing fleets operating in the Convention area, including an observers’ program and ecological risk assessments (ERAs) to determine the impact of the fishery on bycatch species (SPRFMO, 2013a). No progress on this project was found in SPRFMO website.

Most countries list bycatch of other commercial species caught in their fisheries but complete bycatch lists are not known to exist (SPRFMO, 2016c). Peruvian fleets report minor bycatches of chub mackerel in the high seas.

Northern Chile EEZ

Last updated on 28 June 2018

In order to reduce and/or mitigate interference among fisheries and/or discards, an annual decree regarding the TAC establishes the bycatch allowance for this resource throughout the fishery unit, generally at 5% per trip (SUBPESCA, 2015a; 2015b).

The northern Chilean fleets mainly caught jack mackerel as bycatch in the fishery targeting anchoveta (Engraulis ringens) in 2014. The anchoveta artisanal fishery has a limit of 5% in catch of jack mackerel bycatch (MEFT, 2016b). 

HABITAT

Last updated on 8 March 2015

Marine Protected Areas are implemented at the country level. No closures of VMEs or EBSAs have yet been implemented in the SPRFMO convention area (SPRFMO, 2014b), but studies focused on bottom trawl fisheries are in progress (SPRFMO, 2015d; 2016f).

As of December 2009, there are two marine reserves in Peru: Paracas Marine Reserve – extension of 335,000 ha of which 65% correspond to sea waters, created to protect wildlife, especially seabirds such as the Humboldt penguin; the National Reserve of Islands, Islets and Guano Headlands System – contains 22 islands and islets and 11 headlands (140,833 ha) and was created to preserve the continuity of the biological cycle of species that inhabit it and to help preserve fish stocks which straddle its vicinity (Cedepesca, 2010; CPPS, 2010).

Northern Chile EEZ

Last updated on 28 June 2018

In 1991, a reserve zone for artisanal fishing was established by law in Chile, consisting of a 5-nautical-mile zone measured from the coast and spanning from the I Region in the North to the X Region in the South and around the oceanic islands and inland waters. However, since 2006 the industrial fleet has been granted permission to fish jack mackerel and small pelagics for fishmeal production with purse seine gear within the artisanal reserve zone of the III and IV Regions.

There are five marine reserves established in Chile: La Rinconada in the II Region, Isla Chañaral in the III Region, Isla Choros-Damas in the IV Region, Putemún and Puliinque in the X Region. The main objective of these reserves is to conserve natural banks of northern scallop (Argopecten purpuratus), Chilean oyster (Tiostrea chilensis) and giant mussel (Choromytilus chorus) among others and also to protect aquatic vertebrates such as dolphins and penguins.

FishSource Scores

Last updated on 16 July 2019

MANAGEMENT QUALITY

As calculated for 2019 data.

The score is ≥ 6.

The precautionary approach is assumed by the South Pacific Regional Fisheries Management Organization (SPRFMO), which conducts joint assessments, pooling data and expertise from all countries fishing the resource in the assessment unit area. The fishery is regulated by a global agreed catch limit for the high seas and the Chilean EEZ, and by a Peruvian unilateral quota within its EEZ; a quota for the Ecuadorian EEZ could not be located. A rebuilding plan was adopted in 2014 but reference points are still provisional and the proposed harvest control rule (Canales, 2014) and its evaluation (Hintzen et al., 2014) is not yet concluded. Uncertainties were raised in the last Scientific Committee report about the discontinuities in the F to be applied and the constraints in the interannual TAC variability (SPRFMO, 2018a).

As calculated for 2019 data.

The score is 10.0.

This measures the Set TAC as a percentage of the Advised TAC.

The Set TAC is 591 ('000 t). The Advised TAC is 591 ('000 t) .

The underlying Set TAC/Advised TAC for this index is 100%.

As calculated for 2019 data.

The score is ≥ 8.

Within the Central-southern management unit, Chilean catches (391,632 t) are above what is the partial quota assigned (278,536 t) but the country transferred quotas from the SPRFMO members in the amount of 76,000 t, which summed up to the overall TAC (at 371,887 t for 2018 (from MEFT, 2017) results in 447,887 t. Therefore, total Chilean catches at 402,528 t (391,632 t for the Central-southern MU and 10,896 t for the Northern MU) did not overpass what was allowed.

STOCK HEALTH:

As calculated for 2018 data.

DATA NOTES
  1. Score about the Management strategy has been determined qualitatively based on the available information, as a harvest control rule (rebuilding plan) has been proposed (Canales 2014) and is officially adopted even if uncertainties were recently raised by the Scientific Committee (SPRFMO 2018).
  2. The assessment model considers the whole assessment unit, as well as catches from all fishing countries operating on this resource. Under the SPRFMO, a TAC is recommended for 2019 for the whole assessment unit (591,000 tonnes) (SPRFMO 2018). As agreed by the members and the Cooperating Non-Contracting Parties (CNCPs) the overall TAC for 2019 was set at 591,000 tonnes for the entire assessment unit and catches should not overpass 531,061 tonnes within the SPRFMO convention area (SPRFMO 2019). Partial scores are made available for both Chilean management units, and Ecuadorian and Peruvian national waters (MU). 
  3. Catch time-series is from the South Pacific Regional Fisheries Management Organization (SPRFMO) report and combine data of the four fleets operating for the resource and considered in the assessment. Fleet 1: coastal purse seine fishery in northern Chile (XV-II regions); fleet 2: purse seine fishery in central-south Chile that extends into the high seas (III-X regions); fleet 3: the far-north coastal purse seine fisheries occurring in the EEZ’s and Territorial waters of Ecuador and Peru (Cook Islands, Cuba, Ecuador, Peru, Russian Federation); fleet 4: the offshore trawl fleet operating solely in the SPRFMO convention area (Belize, China, Cuba, European Union with Netherlands, Faroe Islands, Japan, Korea, Peru, Russian Federation, Ukraine and Vanuatu). The value for 2018 catch is preliminary (SPRFMO 2018) but was used for the stock assessment thus was included in the datasheet, meaning the score for Fishers' compliance relates to 2018.
  4. Fishing mortality (F), spawning stock biomass (SSB) and FMSY time-series are from the 2018 SC-SPRFMO report. SSBMSY is the temporary target reference point fixed at 5,500,000 tonnes (identified as BMSY in the SPRFMO report). A dynamic SSBMSY is determined yearly but was not considered in the datasheet because only the fixed reference point is used to determine the stock status. 80% of SSBMSY triggers Flow according to the harvest control rule (rebuilding plan) in place (Canales 2014)(SPRFMO 2018). The reference points considered by the Chilean entities were not included in the datasheet; only the information made available by SPRFMO is assumed (SPRFMO 2018)
Northern Chile EEZ

Last updated on 2 July 2019

  1. The Chilean advised TAC is given for the whole Chilean management area and not for each partial management unit (Central-southern or Northern Chile) therefore it is not shown in the data file. The IFOP report with the 2018 status was not available at the time of this update. The advised TAC is issued by the Chilean Scientific Committee for the Jack mackerel fishery (CCT-J) which is assumed as an advisory body. For 2019, the Chilean advised TAC between 476,800 and 596,000 t (average at 536,400 t) (CCT-J 2018), it is not coincident with what was agreed by the SPRFMO Scientific Committee (SPRFMO 2018)
