This is a prototype of an automatic report that documents how the user specified the operating model and their various justifications.

2 Introduction

  1. 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. (from assessment report: file:///C:/Users/abenh/Desktop/Faroe%20Islands%20haddock%20-%20SA%20report%2014.12.2016%20Final.pdf) “The fishery is a mixed cod-haddock and saithe fishery where cod is the most important species. The fishery takes place both in the Norwegian, the Svalbard as well as in the Russian fishing zones of the Barents Sea. The dominating gears are bottom trawl (68%) and long line (12 %) the remaining 20% is taken by a mixture of gears including gill nets, jiggings a.o., ICES (2016) . Recent catches are slightly below 200 kt, Figure 2. Management is based on a management plan agreed between Norway and Russia in the Joint Norwegian-Russian Fisheries Commission (JNRFC) and implemented in Norwegian and Russian legislation. The haddock stock as is the cod stocks are at very high level. Haddock is subject to annual analytical age-based assessments with appropriate biological reference points being set, and are subject to an internationally agreed management plan and harvest control rule. Reference points have been defined and tested by ICES; ICES considers both the plans and the control rules to be consistent with both the precautionary and MSY-framework approaches. The spawning stock biomass of haddock is currently above biological reference levels and ICES considers the haddock stock to retain full reproductive capacity (ICES, 2016).”

  2. Describe the stock’s ecosystem functions, dependencies, and habitat types. (from “The relatively broad shelf surrounding the Faeroe Islands in the northeast Atlantic Ocean comprises the Faeroe Plateau LME. The islands and their shelf are affected by a branch of the North Atlantic Drift current, which flows north through this area. Commercial stocks inhabiting this LME include cod, herring, and capelin; the area also serves as important feeding grounds for pilot whales and other marine mammals.”

  3. Provide all relevant reference materials, such as assessments, research, and other analysis. Assessment report: file:///C:/Users/abenh/Desktop/Faroe%20Islands%20haddock%20-%20SA%20report%2014.12.2016%20Final.pdf FishBase: Assessment report: Paper: Report: Assessment report:

3 Fishery Characteristics

3.1 Longevity

Very short-lived (5 < maximum age < 7)
Short-lived (7 < maximum age < 10)
Moderate life span (10 < maximum age < 20)
Moderately long-lived (20 < maximum age < 40)
Long-lived (40 < maximum age < 80)
Very long-lived (80 < maximum age < 160)
According to the catch at age tables 5.4-5.6 provided in the assessment report:

3.2 Stock depletion

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)
Although no informaiton on stock depletion, the assessment study reports that the current biomass is above the “precautionary biomass below which spawning stock biomass should not beallowed to fall to safeguard it against falling to Blim.” (from file:///C:/Users/abenh/Desktop/Faroe%20Islands%20haddock%20-%20SA%20report%2014.12.2016%20Final.pdf)

3.3 Resilence

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)
No information about steepness was provided in the assessment reports.
