Exploitation rateNone-Low Fishing MortalityNo or low fishing mortalityGray
Abundance levelUnknown Stock SizeUncertain/Not assessed

Acoustic surveys series terminated in 1994 indicated a stock at a low level. Although biomass indices have increased in recent years, bottom trawl surveys are not considered a satisfactory basis for a stock assessment of a pelagic species.

Exploitation
 

Capelin was caught in a directed trawl fishery. There is low bycatch in other trawl fisheries. The fishery is regulated by quota and has been under moratorium since 1995, and there were no reported catches between 1994 and 2013. Recent catch estimates and TACs (t) are as follows:

Not defined.
Projection

Quantitative assessment of risk at various catch options is not possible for this stock at this time.
Assessment Model
Analytical assessment
Results

Assessment was based on evaluation of trends in acoustic survey data (1975 – 1994) and bottom trawl surveys (1995 – 2014). Bottom-trawling is not a satisfactory basis for a stock assessment of a pelagic species. At best the assessment is only indicative of major changes in abundance.

Next full assessment is scheduled for 2018. Unless an acoustic survey is available, Scientific Council will be unable to produce more specific advice.

Biomass



Human impact

Low fishery related mortality due to moratorium and low bycatch in other fisheries. Other sources (e.g. pollution, shipping, oil-industry) are considered minor.

Biological and environmental interactions

Changes in growth, maturity and recruitment are linked to temperature on the Grand Banks. Recent increases in temperature (STACFEN 2015) may provide more favorable conditions for capelin. Cod in Div. 3NO has increased slightly in recent years, and may cause increased natural mortality through predation.
Scientific Advice

Special comments

Bottom-trawling is not a satisfactory basis for a stock assessment of a pelagic species and survey results are indicative only. Investigations to evaluate the status of capelin stock should utilize trawl acoustic surveys to allow comparison with historical time series.
Management
Management unit: Yes

Management Advice

Recommendation for 2016-2018

No directed fishery.
Management Objectives

No explicit management plan or management objectives defined by Fisheries Commission. General convention objectives (GC Doc. 08-03) are applied. Advice is based on qualitative evaluation of biomass indices in relation to historic levels.

Stock definition for management purposes

The capelin stock is distributed in Div. 3NO, mainly on the Grand Bank.
