A multidisciplinary approach using genetic markers and biological tags in horse mackerel (Trachurus trachurus) stock structure analysis
The aim of this project is to assess the stock structure of the horse mackerel (Trachurus trachurus), which is an important target species in many north-east Atlantic and Mediterranean fisheries. The project will provide information currently lacking for an effective definition of horse mackerel stock boundaries, and will evaluate the status of the horse mackerel populations. The overall objective will be achieved integrating the results from several techniques such as genetic markers, other biological tags like morphometric studies and the use of parasites, physical tagging and life history traits (growth, reproduction and distribution). The genetic stock assessment will be performed by means of five different genetic approaches comprising the analysis of allozymes, mitochondrial DNA and microsatellite DNA. The proposed research will therefore set-up and improve multi-disciplinary tools for fish stock identification. It will also provide an exhaustive knowledge of horse mackerel stock structures, in order to allow an enhanced management of the horse mackerel resource in European Union waters in the short, medium and long term.
General information on Horse Mackerel
(Species determination, migration, reproduction, food, physiology, ecology...)
(Catches, catch distribution, fleets...)
(Stock definitions, assessments, biomass, fishing mortality, management reference points and considerations...)
This project is funded by the EU Commission within the 5th framework program, Quality of Life and management of Living Resources (Key Action 5: Sustainable agriculture, fisheries and forestry, ...)
Purpose of this website
This website was set up mainly to ease the communication between project partners. It is, however, also expected to give more general information about our research to the public. We will add research results and facts on the biology, assessment and distribution of the horse mackerel occasionally.
Objectives of the Project
The overall objective of this project is the biological stock identification of the horse mackerel (Trachurus trachurus) throughout its whole range, from North-eastern Atlantic to Mediterranean Sea. This goal will be achieved integrating both established and innovative approaches such as genetic markers, other biological tags (morphometry, parasites), tagging experiments and life history traits (growth, reproduction and distribution). The proposed research will therefore set-up an improved multi-disciplinary tool for fish stock identification, and an exhaustive knowledge of horse mackerel stock structure, in order to allow an enhanced management of this resource in EU waters in short, medium and long term.
