Trainee “Assessment of Mediterranean fish stocks productivity and susceptibility and analysis of historical time series”

Short description of activity:
The FISHREG action of the JRC Maritime Affairs Unit (http://fishreg.jrc.ec.europa.eu) supports fisheries data collection and provides scientific advice to fisheries
management under the Common Fisheries Policy (CFP) remit. To this end it ensures the coordination of the Commission’s Scientific, Technical and Economic Committee for Fisheries (STECF) and collects and maintains fisheries data reported by EU Member States in the framework of the Data Collection Framework (DCF; Commission Regulation (EC) No. 665/2008).
As part of its activities FISHREG assesses Mediterranean fisheries. Currently in the Mediterranean 85% of the assessed stocks are overfished. Overall not more than 20
species of commercial interest are assessed, many only sporadically. There persists a high uncertainty on what is the status of at least 30-40 other important species.
Additionally there is a need to define which species should be assessed in the coming years.
The implementation of a Productivity Susceptibility analysis, a semi-qualitative method, will highlight the most vulnerable stocks, even if falling under the category
of data poor stocks, and help prioritize stock status evaluation.
One important premise to scientific advice feeding into fisheries management is the availability of fisheries data reflecting the history of exploitation. In current
Mediterranean assessments the oldest available data start from 1994, while commercial exploitation has been enduring for at least 100 years. The availability of trawl survey data and landings (1920-1990), although complicated to model can help identify trends in biomass and more solid reference points for fisheries management.
The trainee would be involved in the collection and validation of life history parameters of Mediterranean fish stocks and support an analysis of stocks
productivity and susceptibility. In addition the trainee will be involved in extraction and preparation of historical experimental trawl survey and landings data and support the data analysis.
Qualifications:
A Bs/Ms in marine biology/fisheries.
Good quantitative background, a plus would be R programming skills and knowledge of regression models
Expertise on Mediterranean fisheries is preferred
The trainee will probably have the opportunity to participate in R and/or FLR training courses provided by the JRC.
Mandatory language skills:
- For EU nationals: knowledge of at least 2 Community official languages, of which one should be English, French or German. Required 2nd language level is B2
according to the Common European Framework of Reference for Languages.
- For non-EU nationals: very good knowledge of English, French or German. Required level of the language is C2 according to the Common European Framework of
Reference for Languages.
Other requirements are according to the Rules Governing the Traineeship Scheme of the Joint Research Centre.
