Introduction
Describe the history and current status of the fishery, including fleets, sectors, vessel types and practices/gear by vessel type, landing ports, economics/markets, whether targeted/bycatch, other stocks caught in the fishery. Historically, capelin was captured domestically on spawning beaches for food, bait and fertilizer. A directed offshore fishery began in the 1970’s, but was closed between 1979 and 1992 (depending on the area). Also during the 1970s, and inshore roe fishery developed. “The inshore fishery has been prosecuted by capelin traps, purse seines and, to a lesser extent, beach seines. Since 1998, modified beach seines called “tuck seines” have been deployed because capelin stayed in deeper waters and were unavailable to capelin traps and conventional beach seines. The use of tuck seines or capelin traps has varied from location to location…The inshore fishery has been prosecuted by capelin traps, purse seines and, to a lesser extent, beach seines.

Describe the stock’s ecosystem functions, dependencies, and habitat types. Juveniles can be in bays and offshore areas. In spawning season (June and July), spawning schools migrate to beaches and demersal spawning sites. Historically, spawners were age 3 and 4; since 1990s spawners are now age 2 and 3. Larvae eat small invertebrates and are preyed upon by larger invertebrates; older fish eat copepods (O’Driscoll et al. 2001). Capelin are an important food source among larger predators; they are preyed upon by whales, seals, cod and seabirds (Montevecchi et al. 2007; Capelin stock assessment 4RST.pdf; Capelin stock assessment SA2 + 3KL.pdf).

|
Moderately long-lived (20 < maximum age < 40)
|
Long-lived (40 < maximum age < 80)
|
Very long-lived (80 < maximum age < 160)

Stock depletion
Answered
|
Crashed (D < 0.05)
|
Very depleted (0.05 < D < 0.1)
|
Depleted (0.1 < D < 0.15)
|
Moderately depleted (0.15 < D < 0.3)
|
Healthy (0.3 < D < 0.5)
|
Underexploited (0.5 < D)
|
Justification
|
Capelin abundance has fluctuated wildly over the last 50 years and is largely environmentally driven. No carrying capacity has been estimated, so no depletion level is known.
|

Resilence
Answered
|
Not resilient (steepness < 0.3)
|
Low resilience (0.3 < steepness < 0.5)
|
Moderate resilence (0.5 < steepness < 0.7)
|
Resilient (0.7 < steepness < 0.9)
|
Very Resilient (0.9 < steepness)
|
Justification
|
No estimates of steepness are available.
|

Historical effort pattern
Answered
|
Stable
|
Two-phase
|
Boom-bust
|
Gradual increases
|
Stable, recent increases
|
Stable, recent declines
|
Justification
|
No index of fishing effort is available. The fishery was confined to inshore areas until the 1970s when an offshore fishery was developed. This fishery was closed by 1992. Meanwhile, an inshore roe fishery started in the 1980s and has continued, although effort has declined through the 2000s due to market constraints and low prices (Capelin stock assessment SA2 + 3KL.pdf).
|

Inter-annual variability in historical effort
Answered
|
Not variable (less than 20% inter-annual change (IAC))
|
Variable (maximum IAC between 20% to 50%)
|
Highly variable (maximum IAC between 50% and 100%)
|
Justification
|
No direct information; but no indication that effort is particularly variable from year-to-year
|

Historical fishing efficiency changes
Answered
|
Declining by 2-3% pa (halves every 25-35 years)
|
Declining by 1-2% pa (halves every 35-70 years)
|
Stable -1% to 1% pa (may halve/double every 70 years)
|
Increasing by 1-2% pa (doubles every 35-70 years)
|
Increasing by 2-3% pa (doubles every 25-35 years)
|
Justification
|
The fishery has changed dramatically over the last 50 years. Each change is associated with methods for catching the new target of the fishery, and the fishery slowly adapts to improve efficiency. For example, since 1998, the fishery has shifted from beach seines to ‘tuck seines’, which can more effectively target deeper spawning capelin.

Future fishing efficiency changes
Answered
|
Declining by 2-3% pa (halves every 25-35 years)
|
Declining by 1-2% pa (halves every 35-70 years)
|
Stable -1% to 1% pa (may halve/double every 70 years)
|
Increasing by 1-2% pa (doubles every 35-70 years)
|
Increasing by 2-3% pa (doubles every 25-35 years)
|
Justification
|
I presume moderate improvements in catch efficiency as the fishery improves targeting.

Length at maturity
Answered
|
Very small (0.4 < LM < 0.5)
|
Small (0.5 < LM < 0.6)
|
Moderate (0.6 < LM < 0.7)
|
Moderate to large (0.7 < LM < 0.8)
|
Large (0.8 < LM < 0.9)
|
Justification
|
Capelin mature at age-2 to age-3 (230-300mm); maximum length is 360mm (Wheeler et al. 2009).
|

Selectivity of small fish
Answered
|
Very small (0.1 < S < 0.2)
|
Small (0.2 < S < 0.4)
|
Half asymptotic length (0.4 < S < 0.6)
|
Large (0.6 < S < 0.8)
|
Very large (0.8 < S < 0.9)
|
Justification
|
Fish are caught primarily by seine and trawl targeting mature fish. Gear is relatively selective but catches fish as they mature.
|

Selectivity of large fish
Answered
|
Asymptotic selectivity (SL = 1)
|
Declining selectivity with length (0.75 < SL < 1)
|
Dome-shaped selectivity (0.25 < SL < 0.75)
|
Strong dome-shaped selectivity (SL < 0.25)
|
Justification
|
There does not appear to be any decline in selectivity with age because all fish spawn in the same areas and all mature fish are vulnerable to the gear.
|

Discard rate
Answered
|
Low (DR < 1%)
|
Low - moderate (1% < DR < 10%)
|
Moderate (10% < DR < 30%)
|
Moderate - high (30% < DR < 50%)
|
High (50% < DR < 70%)
|
Justification
|
Discarding of males was historically high because the fishery was targeting roe. More recently, changes to regulations has prohibited at-sea discards and markets have opened for capelin as food for zoo animals (Capelin stock assessment 4RST.pdf and Capelin stock assessment SA3 + 3KL.pdf).
|

Post-release mortality rate
Answered
|
Low (PRM < 5%)
|
Low - moderate (5% < PRM < 25%)
|
Moderate (25% < PRM < 50%)
|
Moderate - high (50% < PRM < 75%)
|
High (75% < PRM < 95%)
|
Almost all die (95% < PRM < 100%)
|
Justification
|
Time to mortality (due to air exposure) is extremely low (Benoit et al. 2013); post release mortality assumed to be near 100%.
|

Recruitment variability
Answered
|
Very low (less than 20% inter-annual changes (IAC))
|
Low (max IAC of between 20% and 60%)
|
Moderate (max IAC of between 60% and 120%)
|
High (max IAC of between 120% and 180%)
|
Very high (max IAC greater than 180%)
|
Justification
|
IAC is very high for this species (see Figure 7.pdf (from Capelin stock assessment SA3 + 3KL.pdf), which does not include the highly anomalous year class from early 1990s.

Management Characteristics
Types of fishery management that are possible
Answered
|
TAC (Total Allowable Catch): a catch limit
|
TAE (Total Allowable Effort): an effort limit
|
Size limit
|
Time-area closures (a marine reserve)
|
Justification
|
1. Describe what, if any, current management measures are used to constrain catch/effort. The fishery has a TAC. Catches are monitored using logbooks, dockside monitoring and VMS in purse seine vessels; the fishery is closed when TAC is exceeded or when fishing ceases due because price exceeds revenue. The fishery opens for a brief period each spring/summer (depending on area). Openings are specific to different areas of the coast.
2. Describe historical management measures, if any.
3. Describe main strengths and weaknesses of current monitoring and enforcement capacity. Strengths There may be on-board observers Fish may only be offloaded in the presence of a certified dockside observer Compliance occurs through a combination of routine patrols; dockside inspections; at-sea inspection; aerial surveillance; VMS; at-sea observer coverage.
Weaknesses The recreational sector is not monitored There is recognition that there will be complex non-compliance, such as trans-shipment vessels, unmonitored landings, etc. These are prioritized by compliance officers, but remain an issue.
4. Describe and reference any legal/policy requirements for management, monitoring and enforcement.

TAC offset: consistent overages/underages
Answered
|
Large underages (40% - 70% of recommended)
|
Underages (70% - 90% of recommended)
|
Slight underages (90% - 100% of recommended)
|
Taken exactly (95% - 105% of recommended)
|
Slight overages (100% - 110% of recommended)
|
Overages (110% - 150% of recommended)
|
Large overages (150% - 200% of recommended)
|
Justification
|
The fishery typically underachieves its TAC, though there have been occasional periods where the TAC is slightly overachieved. See Figure 3.png (from Capelin stock assessment SA2 + 3KL.pdf) and Figure 4.png (from Capelin stock assessment 4RST.pdf).
