Influence of offshore oil and gas structures on seascape ecological connectivity
Global Change Biology, Volume 28, Issue 11, Page 3515-3536, June 2022., 2022 Offshore platforms and related fixed structures supporting the oil and gas (O&G) industry are prevalent in all oceans. We review current knowledge on the role of O&G infrastructure in maintaining, altering or enhancing ecological seascape connectivity. There is a paucity of studies assessing connectivity and O&G structures.

Marine and Coastal Fisheries, Volume 14, Issue 2, April 2022., 2022 Abstract Forage fish are schooling species commonly occurring in both offshore pelagic and nearshore coastal habitats. Beyond use by some species for spawning, the dynamics of nearshore habitat use are not well understood. The objective of our study was to evaluate the spring–summer dynamics of forage fish occurrence in nearshore habitats of the Strait

Invasive red king crab affects lumpsucker recruitment by egg consumption [PDF]
, 2012 The invasive red king crab Paralithodes camtschaticus preys on lumpsucker Cyclopterus lumpus eggs. We tested the hypothesis this egg consumption may hamper the recruitment of lumpsucker.

Diet and trophic structure of fishes in the Barents Sea: between empty and full stomachs - large individual variability follows a common pattern. [PDF]
J Fish BiolAbstract More than 27,000 stomachs from 70 species of fish were collected from the Barents Sea in 2015. Quantitative stomach content expressed relative to the body weight of the predator fish (g g−1 as %) varied by four to five orders of magnitude for six species with the largest sample size (Atlantic cod Gadus morhua, haddock Melanogrammus aeglefinus,

Journal of Fish Diseases, Volume 45, Issue 1, Page 153-163, January 2022., 2022 Abstract Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there are challenges with bacterial infections. The frequency of prescription of antibiotic agents to lumpfish is increasing, despite the lack of knowledge about appropriate doses, duration of treatment and ...

Aquaculture Nutrition, Volume 2022, Issue 1, 2022., 2022 The aim of this study was to investigate how the dietary balance between protein, lipid, and carbohydrate affects growth, welfare, and health with focus on immune responses, in lumpfish of body weight ranges 1.7‐10 g and 15‐50 g. A three‐component mixture design, with simultaneous variation of the three macronutrients was applied.

Ecological Monographs, Volume 91, Issue 4, November 2021., 2021 Abstract Sea otter (Enhydra lutris) populations in southwest Alaska declined substantially between about 1990 and the most recent set of surveys in 2015. Here we report changes in the distribution and abundance of sea otters, and covarying patterns in reproduction, mortality, body size and condition, diet and foraging behavior, food availability ...
