SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Loligo pealeii

SPECIES NAME(s)

Longfin squid, Longfin Inshore Squid

Several genetic studies have indicated a single stock between Cape Cod, MA and Cape Hatteras NC, but others have indicated multiple stocks (SEDAR 2010).


ANALYSIS

Strengths

The fishery is well managed through Total Annual Catch limits, Moratorium on new fishery permits, A minimum codend mesh size of 1 7/8 inches to reduce by-catch of other species, Onboard observers, and Possession limits. Discards data is far better quantified in recent years through onboard observer program. Stocks managed by seasonal quotas and other restrictions. Fishery complies with quotas for most years.

Weaknesses

Landings data prior to 1987 is beset with substantial uncertainty (Cadrin and Hatfield 1999). Discards averaged 3.4% of the total landings for the 1989-2009 period but due to lack of quantitative estimates of discards for the period prior to 1989, discards of 3.4% was assumed backwards although foreign fishery might have had a higher percentage of discards.

Options

Consider developing an analytical model to base quota on. Suggest increased data collection to gather information to make an analytical assessments possible in the near future.

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

United States
Small mesh bottom trawls

Last updated on 30 March 2011

The L. pealeii stock has been assessed using length-based virtual population analysis, and Surplus production model in 2002, and 2010, but due to absence of reliable biological reference points the stock is mostly managed through Annual Biological Catch (ABC) Limits in U.S. waters (NFSC 2002; Hendrickson and Jacobson 2006; Moustahfid et al., 2009).

SCIENTIFIC ADVICE

Reference Points

Last updated on 17 Dec 2012

Biological reference points have not been estimated for this stock. The most recent stock assessment in 2010 revealed that current “F” reference point is not appropriate for lightly exploited longfin squid stock (NFSC 2011).

There is a need to define biological reference points before any realistic stock assessment can be undertaken for this stock.

CURRENT STATUS

Last updated on 17 December 2012

The most recent stock assessment was conducted in 2010, which shows that overfishing was not occurring for the longfin inshore squid stock in NW Atlantic waters of USA (NFSC 2011).

Trends

Last updated on 17 Dec 2012

Squid fishery began as early as 1800 in U.S. waters, with longfin squid largely used as bait until 1928. For the period 1928 to 1967, catches ranged from 500-2000 tonnes each year (Lange and Sissenwine 1980). During the 1967-1984 period catches from foreign fishing vessels (averaging 20,130 tonnes) operating in offshore waters dominated the fishery. Since 1987, after the elimination of foreign fishery, domestic fishery was developed, with landings averaging 16,610 mt during the 1987-2009 time period.Landings gradually decreased after the introduction of in-season quotas for the domestic fleet in 2000 (NFSC 2011).

2.MANAGEMENT QUALITY

MANAGEMENT

United States
Small mesh bottom trawls

Last updated on 30 March 2011

Since 2000, the inshore longfin squid has been managed under the guidelines of the Atlantic Mackerel, Squid, and Butterfish Fishery Management Plan (FMP) several management measures apply for vessels operating in this fishery:

Total Annual Catch limits;
Moratorium on fishery permit;
A minimum codend mesh size of 1 7/8 inches to reduce by-catch of other species;
Onboard observers;
Possession limit of 2500 lbs.

Recovery Plans

Last updated on 30 Mar 2011

None are contemplated under the current management plan.

COMPLIANCE

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species
US Atlantic
United States
Small mesh bottom trawls

Last updated on 18 December 2012

The small-mesh bottom trawlers can interact with marine mammals (including pilot whales, common dolphins) species and several large pelagic (swordfish, and a variety of shark, ray, and tuna) species (NOAA 2012).

NOAA is trying to minimise interactions with marine mammals by educating fishermen on actions to undertake in the eventuality of interaction of trawl gear with marine mammals, and by communicating real-time observations on hotspots of marine mammal interactions to the fishermen (NOAA 2012).

Other Species

Some of the by-catch species caught in this fishery include butterfish, hakes, Illex squid, fluke, herring, spiny dogfish, and Atlantic mackerel, swordfish, tuna, sharks and rays (NOAA 2012).

HABITAT

Last updated on 18 December 2012

The habitat characteristics of Longfin Inshore Squid, Loligo pealeii are described in detail in NOAA (2005).

“Squid are found over sandy or muddy habitats, which are less sensitive to impacts from trawling than other habitat types, such as coral” (NOAA 2012).
