Abstract Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 resources—ranging from data‐poor to data‐rich stocks—in the North East Atlantic most likely affected under intermediate emission scenario RCP4.5 towards 2050. This region is one productive waters in subjected pronounced change, especially northernmost part. In this impact assessment, we applied a hybrid solution combining expert...
Abstract The distribution of cod along the Norwegian coast and in fjords from 62°N north to Russian border was examined using data annual trawl surveys carried out between 1995 2001. Based on differences growth zones otoliths, are traditionally classified into two types: Northeast Arctic coastal cod. Both types were found throughout area investigated. catch rate both increased northwards offshore inshore. In a statistical model length at age, abiotic factors such as year capture explained...
The distinction between north-east Arctic cod and Norwegian coastal cod, two major groups of Atlantic (Gadus morhua L.), has for many years been based on different distance shape similarities the first translucent growth zones in otoliths, subjectively decided by visual inspection a binocular. To analyse certainty this technique, four independent readers have classified 263 otoliths total from five geographical areas. For three readers, 82% 89% classification results coincided with genetic...
The Arctic is experiencing increasing water temperatures, leading to a northward shift of Atlantic species into waters. marine ecosystems are therefore subject substantial changes in distributions and occurrence due anthropogenic climate change. cod one the most important commercial fish northern seas. largest known stock migrating Northeast (NEAC) that distributed along Norwegian coast, Barents Sea off Svalbard. Svalbard waters generally reported literature as belonging NEAC ecotype. more...
Abstract Rapid warming at high latitudes triggers poleward shifts of species' distributions that impact marine biodiversity. In the open sea, documented redistributions fish lead to a borealization Arctic fauna. A climate‐driven and increased species diversity are also expected in coastal communities, but they have not been previously on large, biogeographic scale. Here, we investigate temperature change over last 25 years communities along coast Norway. The study area, spanning different...
In autumn 2015, several sources reported observations of large amounts gelatinous material in a north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible organism was identified as physonect siphonophore, Nanomia cara, while ctenophore, Beroe cucumis, and hydromedusa, Modeeria rotunda, were also registered high abundances on couple occasions. To document the phenomena, we have compiled variety data from concurrent fisheries surveys...
Abstract The movement patterns of released hatchery-reared fish determine the geographical scale at which a population may be enhanced, while wild affect management strategies populations. This article investigates (1) if differ between hatchery reared and cod, (2) coastal cod regions. results from large mark-recapture experiment in northern Norway showed that displacement distances (DD) for both were highly skewed. frequency distribution DD was well described by log-normal distribution....
Pinnipeds (seals and sea lions) on breeding beaches hauling areas can be exposed to sonic booms from existing planned civilian supersonic aircraft. Although carpet do not produce detectable threshold shifts in humans, the available anatomical information is adequate extrapolate models for humans pinnipeds. Therefore, rehabilitated stranded California lions (Zalophus californianus), harbor seals (Phoca vitulina), elephant (Mirounga angustirostris) were simulated N-waves with levels up 6 psf...
White leghorn chicken poults (3 weeks and 8 of age) laying pullets (48 were exposed to a series simulated jet aircraft overflights. Poultry in small groups (∼35 birds/pen) barns equipped with U. S. Air Force-designed simulation system. For poult experiments, 72 pens four six times per day for 4 days. experiments hens, 60 two 5-day blocks over 2-week period. Level exposure ranged from 105 dB ASEL down the ambient noise floor barns. Ambient was dominated by poultry vocalizations fan (70–85...
Sonic booms at levels typical for supersonic airlines (<3 psf) are considered harmless to hearing based on laboratory studies. However, data animals difficult generalize other species. Wildlife present a particular problem because experimental efforts induce permanent threshold shift (PTS) cannot be conducted ethical or management reasons. Instead, ‘‘significant’’ temporary (TTS) has been proposed as conservative damage risk criterion (DRC). With this in mind, two series of...
