Together with life-history and underlying physiology, the behavioural variability among fish is one of three main trait axes that determines vulnerability to fishing. However, there are only a few studies have systematically investigated strength direction selection acting on traits. Using in situ behaviour revealed by telemetry techniques as input, we developed an individual-based model (IBM) simulated Lagrangian trajectory prey (fish) moving within confined home range (HR). Fishers...
Abstract The dynamics of fish length distribution is a key input for understanding the population and taking informed management decisions on exploited stocks. Nevertheless, in most fisheries, landed still made by hand. As result, estimation precise at level, but due to inherent high costs manual sampling, sample size tends be small. Accordingly, precision population-level estimates often suboptimal prone bias when properly stratified sampling programmes are not affordable. Recent...
The abundance, nature and possible sources of litter on 32 beaches the Balearic Islands (Mediterranean Sea) were investigated in 2005.Mean summer abundances Balearics reached approximately 36 items m -1 , with a corresponding weight 32±25 g which is comparable to results other studies Mediterranean.Multivariate analyses (principal component analysis redundancy analysis) confirmed strong similarities between islands statistically significant seasonal evolution composition abundance.In (the...

Abstract Harvesting of wild-living animals is often intensive and may selectively target heritable behavioral traits. We studied the exploitation dynamics vulnerability consequences individual heterogeneity in movement-related behaviors free-ranging pearly razorfish ( Xyrichthys novacula ). Using underwater-video recording, we firstly document a fast high rate about 60% adult population removed just few days after opening season. Subsequently, tagged sample individuals with acoustic...
Significance Fish are harvested nonrandomly, potentially inducing selection pressures and adaptations of phenotypes that could impede sustainable natural resource management. To assess the potential for fishing-induced selection, must also be considered, which represents a challenge in broadcast spawning fish wild. We compared harvest on size behavioral traits wild northern pike ( Esox lucius ) population. Harvest body operated opposition. but not acted directly behavior, favoring timid...
Many of the world's oceanic and oceanic‐like islands possessed endemic mammal faunas before they were colonized by humans. These faunas, unbalanced impoverished compared to continental usually lacked large mammalian carnivores. In virtually all cases, arrival humans their domesticants commensals on these is related extirpation numbers insular mammals. extinction events affected at least 27% autochthonous species islands. This percentage rises 35% when volant mammals are excluded. reduction...
Abstract Alós, J., Palmer, M., Grau, A. and Deudero, S. 2008. Effects of hook size barbless hooks on hooking injury, catch per unit effort, fish in a mixed-species recreational fishery the western Mediterranean Sea. – ICES Journal Marine Science, 65: 899–905. The effects (small vs. large) type (conventional barbless) effort (cpue), Balearic Islands (western Mediterranean) are evaluated. Hook was most important predictor deep-hooking, which is reduced by use large hooks. captured another...
Increased timidity is a behavioral response to exploitation caused by combination of learning and fisheries-induced selection favoring shy fish. In our study, the potential for angling-induced change in fish behavior was examined two marine coastal fishes exploited boat recreational fishing Mediterranean (Mallorca, Spain). It expected that mean vulnerability capture surviving individuals would differ across gradient previous exposure angling this effect be present multiple species. The...

Abstract Consistent between‐individual differences in movement are widely recognised across taxa. In addition, foraging plasticity at the within‐individual level suggests a behavioural dependency on internal energy demand. Because behaviour co‐varies with fast‐slow life history ( LH ) strategies an adaptive context, as theoretically predicted by pace‐of‐life syndrome hypothesis, mass/energy fluxes should link and its physiology both between‐ levels. However, mechanistic framework driving...
Abstract The measurement of animal density may take advantage recent technological achievements in wildlife video recording. Fostering the theoretical links between patterns depicted by cameras and absolute is required to exploit this potential. We explore applicability Hutchinson–Waser's postulate (i.e. when stationary at a given temporal spatial scale, average number animals counted per frame), which counter‐intuitive statement for most ecologists managers who are concerned with counting...
Acoustic telemetry techniques are very useful tools to monitor in detail the swimming behaviour and spatial use of fish artificial rearing environments at individual group levels. We evaluated feasibility using passive acoustic welfare sea-cage aquaculture an industrial scale, characterizing for first time diel distribution patterns gilthead seabream (Sparus aurata) fine-scale. Ten were implanted with tags equipped pressure acceleration sensors, monitored a commercial-size period one month....
Informed fishery management decisions require primary input data such as the fluctuations in number of fish landed and length. Obtaining these can be costly if conducted by hand, which is case for length most fisheries. This cost often implies reduced sample sizes, may introduce biases lead to information loss at, example, boat level. The recent boost artificial intelligence applied fisheries provides a promising way improve assessment stocks. We present an operational system using deep...

Two ichthyoplankton surveys were carried out in two areas off Mallorca island (Balearic archipelago, western Mediterranean) June 1996 and August 1996, respectively. The aim of both was to assess the influence physical environmental factors on horizontal distribution larval fish assemblages, focusing larvae large migratory pelagic species. Canonical correspondence analysis (CCA) indicated that survey, patterns mainly conditioned by depth surface water masses: Modified Atlantic Waters (MAW),...
Abstract For decades, disruption of the bilateral symmetry body structures has been related to underperformance and, hence, fitness. In fish, this concept coupled with claimed evidence for increased fluctuating asymmetry (FA) pairs hard structures, such as otoliths under conditions stress, led use otolith FA (OFA) a proxy individual fitness and population success. Interpreting those significant differences in OFA relation stress-inducing environments using them identify suboptimal survival...
Despite the recognised effectiveness of networks Marine Protected Areas (MPAs) as a biodiversity conservation instrument, nowadays MPA network design frequently disregards importance connectivity patterns. In case sedentary marine populations, stems not only from stochastic nature physical environment that affects early-life stages dispersal, but also spawning stock attributes affect reproductive output (e.g., passive eggs and larvae) its survivorship. Early-life are virtually impossible to...
Abstract Increasing sea temperature is a driver of change for many fish traits, particularly fast-growing epipelagic species with short life spans. With warming, altered spawning phenology and faster growth may produce substantially larger body sizes the new cohort, affecting fishery productivity. We present an individual-based model (IBM) that predicts distribution length at catch under observed projected thermal scenarios, accounting mortality, temperature-dependent phenology, temperature-...
