Recovery of algal turfs following removal
(Peer reviewed; Journal article, 2023)As a consequence of the increasing human footprint on the environment, marine ecosystems are rapidly transforming into new configurations dominated by early-successional and weedy life forms. Algal turfs, in particular, ... -
Recreational sea fishing in Europe in a global context—Participation rates, fishing effort, expenditure, and implications for monitoring and assessment
(Journal article; Peer reviewed, 2017)Marine recreational fishing (MRF) is a high-participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative ... -
Recruitment decline in North Sea herring is accompanied by reduced larval growth rates
(Journal article; Peer reviewed, 2013-08-28)The stock of North Sea autumn spawning herring Clupea harengus (L.) has shown an unprecedented 10 yr sequence of sharply reduced recruitment, in spite of a high spawning biomass. Recent work has identified this below-expected ... -
Recruitment of Atlantic cod stocks in relation to temperature and advection of copepod populations
(Journal article; Peer reviewed, 2000-11)The recruitment of Atlantic cod stocks shows different responses to temperature changes. Cod stocks inhabiting the lower temperature range show generally an increase in recruitment with increasing temperature, while cod ... -
Recruitment of shrimp (Pandalus borealis) in the Barents Sea related to spawning stock and environment
(Journal article; Peer reviewed, 2008-10)The shrimp spawn in autumn, and the females carry their eggs as out roe until spring when the larvae hatch. Within a period of 2 months the shrimp larvae settle to the bottom. It has been claimed that the year-class strength ... -
Recruitment regime shifts and nonstationarity are widespread phenomena in harvestable stocks experiencing pronounced climate fluctuations
(Peer reviewed; Journal article, 2023)Methods to reliably identify jump discontinuities in biological time series and to assess the specific contribution of various covariates are rapidly progressing. Here, we took advantage of these statistical improvements ... -
Recruitment Variability in North Atlantic Cod and Match-Mismatch Dynamics
(Journal article; Peer reviewed, 2011-03-07)Background Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in ... -
Recruitment variability of fish stocks in the Barents Sea: Spatial and temporal variation in 0-group fish length of six commercial species during recent decades of warming (1980–2017)
(Peer reviewed; Journal article, 2022)Young-of-the-year (0-group) fish in the Barents Sea have been investigated in an annual joint Norwegian-Russian pelagic trawl survey in autumn, using a standardized procedure since 1980. We use a conceptual framework of ... -
Recurrent convergent evolution at amino acid residue 261 in fish rhodopsin
(Journal article; Peer reviewed, 2019)The evolutionary process that occurs when a species colonizes a new environment provides an opportunity to explore the mechanisms underlying genetic adaptation, which is essential knowledge for understanding evolution and ... -
Recycling pathways in cold-water coral reefs: Use of dissolved organic matter and bacteria by key suspension feeding taxa
(Peer reviewed; Journal article, 2020)Cold-water coral (CWC) reefs are one of the most diverse and productive ecosystems in the deep sea. Especially in periods of seasonally-reduced phytodetritus food supply, their high productivity may depend on the recycling ... -
Red and melanized focal changes in white skeletal muscle in Atlantic salmon (Salmo salar): Comparative analysis of farmed, wild and hybrid fish reared under identical conditions
(Peer reviewed; Journal article, 2023)Selective breeding plays a vital role in the production of farmed Atlantic salmon and has shown success in many aspects. Still, challenges related to fish health and welfare continue to result in significant economic losses. ... -
Red and white chinook salmon (Oncorhynchus tshawytscha): Differences in the transcriptome profile of muscle, liver, and pylorus
(Peer reviewed; Journal article, 2020)Astaxanthin (Ax), the main carotenoid responsible for the distinct red flesh color in salmonids (Oncorhynchus, Salvelinus, Salmo, and Parahucho), is added to the diet of farmed fish at a substantial cost. Despite the great ... -
Redescription and new records of Jansen’s goatfish, P. jansenii (Mullidae), from the Western Pacific and Eastern Indian Ocean.
(Journal article; Peer reviewed, 2017)For Jansen’s goatfish, Parupeneus jansenii (Mullidae), taxonomic knowledge has been rather poor and occurrence information restricted to a few localities only, with verified records from northern Sulawesi and Sunda Street ... -
Redescription of Microsporidium takedai (Awakura, 1974) as Kabatana takedai (Awakura, 1974) comb. n.
(Journal article; Peer reviewed, 2001-04-10)Ultrastructural study of the microsporidian Microsporidium takedai from the muscles of masu salmon Oncorhynchus masou proved that this species can be assigned to the genus Kabatana Lom, Dykova and Tonguthai, 2000. The ... -
Reduced environmental impact of antibacterial agents applied in fish farms using the LiftUp feed system or a hydroacoustic feed detector
(Journal article; Peer reviewed, 1994-07-28)High-performance liquid chromatography was used to quantify residues of oxolinic acid and flumequine in muscle of wild fish caught in the vicinity of fish farms using the LiftUp feed collector system or a hydroacoustic ... -
Reduced migratory performance of farmed Atlantic salmon post-smolts from a simulated escape during autumn
(Journal article; Peer reviewed, 2010-11-10)Escape of migratory finfish species from fish farms, such as Atlantic salmon Salmo salar L., offer a challenge when considering the environmental risks of cage culture. The migratory behaviour of groups of cultured salmon ... -
Reduced physiological performance in a free-living coralline alga induced by salmon faeces deposition
(Peer reviewed; Journal article, 2021)Maerl beds are formed by the accumulation of free-living coralline algae and have considerable ecological significance due to the high diversity of associated fauna and flora. The rapid expansion of the Atlantic salmon Salmo ... -
Reference point based management of Norwegian Atlantic salmon populations
(Peer reviewed; Journal article, 2013)While management according to biological reference points is well established for many commercial marine fisheries, similar systems for more leisure based fisheries for freshwater fishes are less common. This paper describes ... -
