“…However, previous tagging studies of juvenile sea bass (c.a. 36 cm length, larger than those sampled in this study) around the UK coastline suggest that they do have a larger dispersal range than observed in this study, with 55% of recaptures after 100 days within 16 km of their coastal release site (Pickett et al 2004;Pawson et al 2008). This would suggest ontogenetic changes in site fidelity as the fish mature.…”

“…Previous studies using tagging and ultrasound to successfully track populations of mature commercial fish species (e.g. sea bass Dicentrarchus labrax, thin-lipped grey mullet Liza ramada) around European estuaries have shown that mature adults disperse widely (Almeida 1996;Pickett et al 2004;Pawson et al 2008). However, the dispersal patterns of sub-populations of juvenile or larval fish that utilise salt marshes as nursery sites (Cattrijsse and Hampel 2006), and salt marsh specialists, such as the highly abundant common goby Pomatoschistus microps, are not known.…”

High site fidelity and low site connectivity in temperate salt marsh fish populations: a stable isotope approach

et al. 2011

Adult and juvenile fish utilise salt marshes for food and shelter at high tide, moving into adjacent sublittoral regions during low tide. Understanding whether there are high levels of site fidelity for different species of coastal fish has important implications for habitat conservation and the design of marine protected areas. We hypothesised that common salt marsh fish species would demonstrate a high site fidelity, resulting in minimal inter-marsh connectivity. Carbon ((13)C) and nitrogen ((15)N) stable isotope ratios of larvae and juveniles of five common salt marsh fish (Atherina presbyter, Chelon labrosus, Clupea harengus, Dicentrarchus labrax, Pomatoschistus microps), seven types of primary producer and seven secondary consumer food sources were sampled in five salt marshes within two estuary complexes along the coast of south-east England. Significant differences in (13)C and (15)N signatures between salt marshes indicated distinct sub-populations utilising the area of estuary around each salt marsh, and limited connectivity, even within the same estuary complex. (15)N ratios were responsible for the majority of inter-marsh differences for each species and showed similar site-specific patterns in ratios in primary producers, secondary consumers and fish. Fish diets (derived from isotope mixing models) varied between species but were mostly consistent between marsh sites, indicating that dietary shifts were not the source of variability of the inter-marsh isotopic signatures within species. These results demonstrate that for some common coastal fish species, high levels of site fidelity result in individual salt marshes operating as discrete habitats for fish assemblages.

“…For sea bass such behaviour was previously documented at a spatial scale of ~16 km with some individual fish being recaptured at the same tagging/release site many years later. For example, Pawson et al 9. described 17 fish being recaptured at their original tagging locations in south Wales and southwest England during the period 2000–2006.…”

“…In the Northeast Atlantic, European sea bass ( Dicentrarchus labrax ) inhabit the coastal waters of Ireland, England, Wales, France and the Netherlands during the summer months91011. They are a long-lived fish (>20 years)12 and are known to feed on a variety of prey items including shore crabs ( Carcinus ), shrimp ( Crangon ), juvenile plaice and flounder12.…”

“…During autumn and winter, sea bass migrate out of their coastal habitats to spawn and overwinter before returning to coastal foraging locations in spring or early summer. Evidence from previous mark-recapture studies found that many sea bass return to the same areas in successive years, with one study showing that 55% of all recaptured fish were within 16 km of their original tagging location9. Despite this knowledge, we still have little information on the composition of local populations at coastal foraging grounds, including whether they are transient or resident at specific sites for extended periods, the scale of local movements and level of intra and inter-annual site fidelity, and whether the timing of migration is driven by intrinsic or extrinsic factors.…”

Localised residency and inter-annual fidelity to coastal foraging areas may place sea bass at risk to local depletion

For many marine migratory fish, comparatively little is known about the movement of individuals rather than the population. Yet, such individual-based movement data is vitally important to understand variability in migratory strategies and fidelity to foraging locations. A case in point is the economically important European sea bass (Dicentrarchus labrax L.) that inhabits coastal waters during the summer months before migrating offshore to spawn and overwinter. Beyond this broad generalisation we have very limited information on the movements of individuals at coastal foraging grounds. We used acoustic telemetry to track the summer movements and seasonal migrations of individual sea bass in a large tidally and estuarine influenced coastal environment. We found that the vast majority of tagged sea bass displayed long-term residency (mean, 167 days) and inter-annual fidelity (93% return rate) to specific areas. We describe individual fish home ranges of 3 km or less, and while fish clearly had core resident areas, there was movement of fish between closely located receivers. The combination of inter-annual fidelity to localised foraging areas makes sea bass very susceptible to local depletion; however, the designation of protected areas for sea bass may go a long way to ensuring the sustainability of this species.

Stock composition studies using otolith fingerprints have scarcely been developed in freshwater systems. In this context, the La Plata Basin is the second largest fluvialmarine system of South America, where Prochilodus lineatus is the most important fishery resource. Despite the basin importance, estimation of mixed stock composition has not been explored yet. In this paper, the contribution of the two main nursery areas to two fishing stocks (Uruguay and Paraná rivers) of P. lineatus was evaluated using otolith's core microchemistry, considering two groups: subadult (2 years) and adult (4 years). Estimates were made using two maximum likelihood methods. Chemical composition of young-of-year fish caught in nursery areas in 2010 was used as baseline of the models, whereas chemical composition of the core of subadult and adult otoliths was used as sample of unknown origin. Results suggest that the subadult stock from Paraná was not mixed (contribution~100%), whereas the stock from Uruguay had a contribution from the Paraná nursery (1.5 ± 1.2-17.9 ± 3.96%). For the adults, the degree of mixing increased and the contribution from both nursery areas to the Paraná and Uruguay stocks varied between 14.8 ± 4.18% and 85.2 ± 4.18%, respectively. The potential application of otolith fingerprints and maximum likelihood mixture models is here highlighted for determining the relative importance of recruitment sources of fish in the La Plata Basin. Because the contributions of the different nursery areas shared among several nations in turn affect the composition of internationally shared stocks, comprehensive management agreements at the basin level are necessary.
