“…Because of the complexity of the processes involved at different spatial and temporal scales, identifying dispersal pathways and connectivity remains a major challenge in marine ecology (Levin, 2006;Cowen and Sponaugle, 2009;Lowe and Allendorf, 2010). During the last two decades, significant methodological development has been done to assess marine connectivity including population genetics and the development of next-generation sequencing (Benestan et al, 2015;Gagnaire et al, 2015), elemental fingerprinting of calcified structures using natural or artificial tags (Carson et al, 2010;Cuif et al, 2014), and individual-based biophysical modeling taking into account complex coastal hydrodynamics as well as larval biological traits (Robins et al, 2013;Thomas et al, 2014). Although most biophysical models do not integrate settlement and postsettlement processes involved in the recruitment and demographic connectivity of benthic invertebrates (Pineda et al, 2009), they have the advantage to simulate larval pathways and quantify connectivity for multiple larval releases related to the complex spatial and temporal variability of local hydrodynamics.…”

The great scallop Pecten maximus supports one of the most important and valuable commercial fisheries around the British Isles and in the northwest of France, but the resource is mainly managed at the scale of each local fishing ground through a combination of European, national and local measures. To analyse the larval dispersal pathways and connectivity patterns among fishing grounds of the great scallop in the Celtic Sea and the English Channel, a particle tracking model was developed. The model combined a 3D physical circulation model that simulated currents and temperature fields and a scallop larval submodel that took into account a temperature-dependent planktonic larval duration and an active vertical swimming behaviour. Due to the lack of stock assessment at the regional scale, the location of the main fishing grounds was established by combining different sources (e.g. grey literature, unpublished scientific surveys, vessel monitoring data, fishermen) while the spawning biomass of each stock was estimated from landings data. Results indicated that each local stock could not be considered as a single independent management unit and that all stocks except that of the Bay of Brest were connected to neighbouring stocks, suggesting that the management should be defined in a metapopulation context. Three major groups of strongly interconnected stocks including two or three stocks exhibiting high retention and self-recruitment rates and some peripheral stocks with a low self-recruitment rate were defined: the North Brittany and Channel Islands, the eastern English Channel, and the SW of England. Our results were discussed in terms of the definition of management units in comparison with genetic and phenotypic data, and in terms of resource management in a transnational context.

The use of farmed and restocked fish to supplement the worldwide human consumption of fish, recreational fishing stocks, and conservation efforts, is growing at a rapid rate. Yet, monitoring the benefits of using hatchery-raised fish for supplementation is lacking, often due to hatcheries not marking or tagging all fish prior to release, despite a range of easy to apply, cost effective and accurate mass-marking methods being available to mark farmed and restocked fish en masse. Here we review otolith marking techniques that have the capability of mass marking millions of hatcheryreared fish that are, or could be, used for monitoring and compliance purposes. The otolith mass marking methods consist of otolith thermal marking and a range of otolith chemical marking methods (tetracyclines, alizarin compounds, calcein, strontium chloride, stable isotopes of Ba and Sr, and rare earth elements). We assessed and compared marking technique in terms of 1) ease of application, 2) cost of application, 3) mark retention and detectability, and 4) fish welfare. In addition, we determine the suitability of different otolith marking techniques for mass marking entire hatchery populations whether it be for restocking purposes, or for identifying and tracing escapees from aquaculture facilities. We conclude that although some techniques have restricted use due to regulations, the majority of otolith mass marking techniques are simple, easy to apply, cost effective and highly suitable for long term monitoring of hatchery produced fish.
