“…Increased daily detections observed in the study area indicated higher fish mobility, likely related to feeding activity. Such a daily pattern was also recorded for other sparids (Santos et al 2002, Abecasis et al 2013) and labroids (Villegas-Ríos et al 2013). Only the receiver deployed at the release site showed no daily pattern, rather it showed a continuous use of habitat over the 24 h period, due likely to the positive correlation between the number of detections and fish swimming depth.…”

A small escape incident of gilthead seabream Sparus aurata tagged with acoustic transmitters (N = 25) from a commercial farm located in a coastal bay of the eastern Adriatic Sea was simulated to enable evaluation of recapture strategies and escapee management. Over a 3 mo monitoring period, tagged individuals showed spatial distribution closely related to fish farms, where 76 and 68% of tagged fish were present at the farm during the second and third weeks post-release respectively. Upon initial release, escaped seabream had a small total home range (0.142 km 2 ) that encompassed the farm site. Short-term residence differed among tagged fish. Few fish (28%) remained in the proximity of the fish farm for longer than 1 mo; most were likely angled or moved outside the acoustic array. Fish that moved elsewhere have the potential to cause substantial ecological and genetic impact, as they likely are able to quickly adapt to natural conditions. Considering the capture impact of the limited recreational fishery on this small-scale escape event, fish recapture by this type of fishery within 2 wk of escape could be feasible and is highly recommended.

“…It has attracted considerable attention due to three main reasons: (i) it is a target for commercial [22] and recreational fisheries [24], (ii) it is currently used as a cleaner species in northern Europe salmonid fish farms as an alternative to chemical treatments [25,26], and (iii) its phenotypic plasticity and life-history variation have raised questions about its taxonomic status and the possibility that one or more cryptic species could exist.…”

Historical gene flow constraints in a northeastern Atlantic fish: phylogeography of the ballan wrasseLabrus bergyltaacross its distribution range

The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biological and ecological factors intrinsic to each species, namely their dispersion ability. The ballan wrasse (Labrus bergylta), the largest labrid fish along Europe's continental margins, is a target for fisheries and aquaculture industry. The phylogeographic pattern, population structure, potential glacial refugia and recolonization routes for this species were assessed across its full distribution range, using mitochondrial and nuclear markers. The existence of a marked population structure can reflect both recolonization from three distinct glacial refugia and current and past oceanographic circulation patterns. Although isolated in present times, shared haplotypes between continental and Azores populations and historical exchange of migrants in both directions point to a common origin of L. bergylta. This situation is likely to be maintained and/or accentuated by current circulation patterns in the north Atlantic, and may lead to incipient speciation in the already distinct Azorean population. Future monitoring of this species is crucial to evaluate how this species is coping with current environmental changes.

“…The small home range of L. bergylta together with its sedentary behavior highlights the potential use of small marine protected areas as a management tool to ensure a sustainable fishery (Villegas-Ríos et al 2013c). In addition, the use of ballan wrasse as a biological cleaner fish for the control of sea lice on farmed salmonids can reduce the environmental impact of aquaculture (e.g.…”

The ballan wrasse (Labrus bergylta) is a marine fish belonging to the family Labridae characterized by 2 main morphotypes that occur in sympatry: spotty and plain. Previous studies have revealed differences in their life-history traits, such as growth and maturation; however, the genetic relationship between forms is presently unknown. Using 20 recently developed microsatellite markers, we conducted a genetic analysis of 41 and 48 spotty and plain ballan wrasse collected in Galicia (northwest Spain). The 2 morphotypes displayed highly significant genetic differences to each other (F ST = 0.018, P < 0.0001). A similar degree of genetic differentiation (F ST = 0.025, P < 0.0001) was shown using the STRUCTURE clustering approach with no priors at K = 2. In this case, the frequency of spotty and plain morphotypes was significantly different ( 2 = 9.46, P = 0.002). It is concluded that there is significant genetic heterogeneity within this species, which appears to be highly associated with the spotty and plain forms, but not completely explained by them. Given the previously demonstrated biological differences between morphotypes, and the present genetic analyses, we speculate about the convenience of a taxonomic re-evaluation of this species.
