“…This study corroborates the usefulness of the tagging technique in black anglerfish as Landa Pereda and Landa (1997) and Laurenson et al (2005). Moreover, the daily activity pattern and vertical migration behaviour of the northwest Atlantic anglerfish, L. americanus, have been reported, based on data storage tags (Rountree et al, 2006).…”

“…The overall recapture rates obtained in the present study were lower than those estimated for white anglerfish tagged in northern European waters (4.5%) (Laurenson et al, 2005), and for L. litulon tagged in Japanese waters (5.6%) (Kitazawa and Yamamoto, 2002). However, the recapture rates of those studies are within the range of values estimated for different gear types and areas (Table 3).…”

“…Their study showed that white anglerfish is able to cover large distances and that interaction is likely to occur among stocks. The longest distance, 876 km, travelled by a white anglerfish was recorded by Laurenson et al (2005). They also showed new examples of movements among stocks, i.e.…”

Movements of black and white anglerfish (Lophius budegassa and L. piscatorius) in the northeast Atlantic

a b s t r a c tWithin the frame of an international tagging program which has been carried out since 1995, movements of black and white anglerfish (Lophius budegassa and L. piscatorius) in Southern European waters were studied. This is the first large-scale study on movements of tagged black anglerfish. A total of 877 black anglerfish (6-88 cm total length) and 1326 white anglerfish (15-137 cm total length) were tagged. Times at liberty ranged from 1 to 665 days, with recapture rates of 21 (2.4%) and 50 (3.8%), respectively. A description of our tagging procedures is presented, together with the influences of the gear used, fish length and area of tagging on recapture rates. The type of fishing gear was the main factor affecting recapture rates. Fish length was neither related to the displacement distance nor to the time at liberty while the displacement distance was related to the time at liberty. Recapture locations suggested that movements occurred both in-and offshore. The largest displacement recorded was 408 km of a black anglerfish from southern to northern Bay of Biscay. The movements of the anglerfish indicate a mixing between northern and southern populations which may have strong implications for the current geographical boundaries of the stocks from a management perspective. Here, movement of white anglerfish between the Le Danois Bank and the Cantabrian continental shelf is reported for the first time.

“…Incorporating habitat partly addresses the concern that observed differences in Laurenson et al (2005) mean length may be primarily driven by the proximity of sampling sites to settlement or nursery areas where abundance of small individuals would be expected to reduce mean length. However, this potential effect on our results is not excluded by our current study and merits further research.…”

“…monkfish (Laurenson et al 2005) and whiting (Tobin et al 2010), demonstrate 'partial migration' (see review in Chapman et al 2012), whereby the majority of fish move little, but a minority of individuals pursue long-range excursions. Our results suggest that this 1 3 strategy is rare enough that it does not dilute spatial correlations between fishing pressure and fish population length structure.…”

Footprints in the sand: a persistent spatial impression of fishing in a mobile groundfish assemblage

are rarely considered to be localized for management purposes, and associated spatial management is far less developed than for terrestrial habitats (Foley et al. 2010) where most widely distributed species are abundant in only a few 'hotspots ' (Brown et al. 1995). In the NE Atlantic, demersal fisheries are typically managed under the implicit assumption that the target population (stock) can be treated as spatially homogeneous within its range. The justification of this assumption depends on movement rates of fish and the degree of spatial heterogeneity in relevant fishing activity. Many pelagic fishes may indeed experience fishing mortality at the regional scale of management, because these species can move freely across large areas and are targeted by highly mobile fishing fleets. In contrast, the vulnerability of sessile (especially hard bodied and shelled) organisms can vary strongly at the scale of a few metres (depending on the footprint of trawl ground gear, e.g. Kaiser et al. 2006) or even less (for hand-gathered stocks such as scallops, e.g. Morsan 2007). It seems likely that fishing impacts on bottom-dwelling species ('groundfish') operate at an intermediate spatial scale: groundfish communities show strong patchiness, in association with benthic habitat and community composition (Reiss et al. 2010). The spatial distribution of demersal fishing (predominately bottom trawling) is also typically heterogeneous, showing strong patterns of local intensity that can remain stable over the years (Hinz et al. 2003;Shephard et al. 2011Shephard et al. , 2012b.In a marine landscape of patchy fishing activity, the impact of fishing on a given stock may depend strongly on distribution and movement of individuals across activity gradients. Movement patterns and rates of mobile organisms reflect many factors including niche space, habitat selection, optimal foraging and inter-specific interactions. Habitat seems to be a strong driver of groundfish distribution; many species form sub-populations in space (Metcalfe Abstract Fishing is well known to curtail the size distribution of fish populations. This paper reports the discovery of small-scale spatial patterns in length appearing in several exploited species of Celtic Sea demersal 'groundfish'. These patterns match well with spatial distributions of fishing activity, estimated from vessel monitoring records taken over a period of 6 years, suggesting that this 'mobile' fish community retains a persistent impression of local-scale fishing pressure. An individual random-walk model of fish movement best matched these exploitation 'footprints' with individual movement rates set to <35 km per year. We propose that Celtic Sea groundfish may have surprisingly low movement rates for much of the year, such that fishing impact is spatially heterogeneous and related to local fishing intensity.

ABSTRACT1. Recent and projected future changes in the temperature and chemistry of marine waters around the UK and Ireland are having, and will in the future have, effects on the phenology, productivity and distribution of marine fish and shellfish. However, the overall consequences are still hard to predict because behaviour, genetic adaptation, habitat dependency and the impacts of fishing on species, result in complex species' responses that may be only partially explained by simple climate envelope predictions.2. There is a broad body of evidence that climatic fluctuations are playing an important role in changing fish distributions and abundances, which is discernible against the background of trends in abundance due to fishing. During warm periods, southern species have tended to become more prominent and northern species less abundant. However, the changes in distribution are often more complicated than might be expected from a simple climate envelope approach, partly due to ocean circulation patterns which create invasion routes for southern water species into the North Sea from the south and from the north via the continental shelf west of Britain and Ireland.3. The eventual population-scale impacts of ocean acidification on fish and shellfish are currently very difficult to predict. However, the scant evidence suggests that indirect food web effects arising from the enhanced sensitivity of calcifying planktonic organisms may be important, and the direct effect on fish sensory systems leading to subtle influences on behaviour with possible population-level implications are possible.4. In British waters, the lesser sandeel (Ammodytes marinus) is identified as being at particular risk from climate change. Owing to its strict association with coarse sandy sediments it is unable to adapt its distribution to compensate for warming sea temperatures. Sandeels are a key link in the food web, linking primary and zooplankton production to top predators.
