Technical Report

This workshop is the third in a series of workshops on guidelines for developing Management Strategy Evaluations (MSEs) within ICES, and was intended to explore some of the issues that arose out of workshops that actually developed MSEs for a range of ICES stocks since the second MSE guidelines workshop was held in early 2019. It is intended that r...
Technical Report
The purpose of the meeting was to bring up to date the methodologies and technical specifica-tions that should be incorporated in Management Strategy Evaluation (MSE) work in ICES. The workshop was tasked with reviewing recent methodological and practical MSE work conducted in ICES and around the world, as well as the guidelines provided by the 201...

A Benchmark on pelagic stocks (WKPELA2018), chaired by External Chair Katja Enberg*, Norway, and ICES Chair Pieter-Jan Schon*, UK, and attended by three invited ex- ternal experts, Verena Trenkel, France, Ashleen Benson, US, and Bjarki Elvarsson, Iceland, will be established and meet for a three-day data evaluation meeting at ICES Headquarters 4–6,...
Article
There are currently no dedicated recruitment survey data available in support of the assessment of the abundance and distribution of Northeast Atlantic (NEA) mackerel (Scomber scombrus), one of the most widespread and commercially important fish stocks in the North Atlantic. This is despite the fact that an estimate of recruitment is an important r...
Article
Full-text available
A comparison of growth data (fish length) with latitude shows that southern juvenile mackerel attain a greater length than those originating from further north before growth ceases during their first winter. A similar significant relationship was found between the growth in the first year (derived from the otolith inner winter ring) and latitude fo...
Data
Mean body length of mackerel at the end of the first growth season (January-March) by latitude (including 54–61°N). (TIF)
Data
L1 (otolith growth from hatch to first winter) from spawning mackerel by latitude (including 54–61°N). (TIF)
Data
Start model and parameter estimate for final models based on the entire area. (DOCX)
Data
Sagittal otolith showing L1 (otolith growth from hatch to first winter). (TIFF)
Article
Full-text available
It has been suggested that observed spatial variation in mackerel fisheries, extending over several hundreds of kilometers, is reflective of climate-driven changes in mackerel migration patterns. Previous studies have been unable to clearly demonstrate this link. In this paper we demonstrate correlation between temperature and mackerel migration/di...
Data
Temperature time series from November–January 1977–2010 northern North Sea used in the analysis of mackerel distributions (solid line as 3 year running mean). Temperature time series from February–March 1985–2010 west of Scotland (dashed line as 3 year running mean). Both series modeled as described in material and methods. (TIF)
Data
3 year running means of temperature time series 1948–2010. Red: Primary temperature series in November–January northern North Sea. Modeled as described in material and methods for the shorter time series. Black: Hadley sea surface temperature anomaly in November–January 55–65 N 10 W–5 E (black). Data from Hadley Centre SST data set (HadSST2) [17]....
Data
Table with temperature model parameter estimates. (DOC)
Data
Mackerel landings from commercial fisheries and mackerel catches from fisheries independent bottom trawl surveys. Data from January–March are shifted back one year to match data in the same season from October–December. (TIF)

Simmonds, E. J., Campbell, A., Skagen, D., Roel, B. A., and Kelly, C. 2011. Development of a stock–recruit model for simulating stock dynamics for uncertain situations: the example of Northeast Atlantic mackerel (Scomber scombrus). – ICES Journal of Marine Science, 68: 848–859. The assumption of a relationship between recruitment and a spawning sto...

An intensive series of observations off the Holderness coast was followed by a related set of modelling applications. Observations included: aircraft and satellite remote sensing, H.F. and X-band radar, ship surveys and in situ instruments on the sea bed and at the sea surface. These observations aimed to monitor, over three successive winter perio...

Observations of sea surface slope and along-channel current from two experiments are used to explore the dynamical balance in the tidally energetic Menai Strait. A regression analysis is used to deduce a new value for the sea-bed frictional drag coefficient which achieves a close balance of the forces involved. The regression results are consistent...

The free-fall FLY profiler has been used to determine the variation in energy dissipation ϵ in the water column over a tidal cycle at mixed and stratified sites in the Irish Sea. It was found that ϵ exhibits a strong M4 variation with a pronounced phase lag that increases with height above the bed. In mixed conditions this M4 signal, which extends...
