Above Water Deterrents Reduce Auk Bycatch in Gillnet Fisheries off the United Kingdom

Conservation Letters, Volume 19, Issue 5, September/October 2026.
ABSTRACT Seabird bycatch in gillnet fisheries is a globally pervasive conservation issue, yet evidence for effective, scalable mitigation remains limited. In a gillnet fishery off the United Kingdom (1057 sets), we evaluated two above water deterrents (AWDs); “scarybird” kites (“kites” hereafter) and looming‐eyes buoys (LEBs) for reducing seabird ...

Produced water from North Sea offshore oil platforms causes a suite of biological effects on developing lumpfish (Cyclopterus lumpus) eggs. [PDF]

, 2020
This study investigated the impacts of several produced waters (PWs) from the North Sea on developing Cyclopterus lumpus larvae. Larvae were exposed for 96 hours early in development to 3 concentrations of 5 different PW solutions. They were then allowed

Phagocytosis and respiratory burst activity in lumpsucker (Cyclopterus lumpus L.) leucocytes analysed by flow cytometry. [PDF]

PLoS ONE, 2012
In the present study, we have isolated leucocytes from peripheral blood, head kidney and spleen from lumpsucker (Cyclopterus lumpus L.), and performed functional studies like phagocytosis and respiratory burst, as well as morphological and cytochemical ...

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, Volume 109, Issue 3, Page 1760-1770, September 2026.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Effects of dietary lipid level on growth, digestive physiology and disease resistance in lumpfish (Cyclopterus lumpus) [PDF]

, 2023
Lumpfish (Cyclopterus lumpus) aquaculture has expanded greatly in recent years due to demands for sea lice cleanerfish from the salmon industry. There are knowledge gaps in lumpfish digestive physiology, nutrient requirement and implications of nutrition

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

Journal of Fish Diseases, Volume 49, Issue 9, September 2026.
ABSTRACT Piscirickettsia salmonis is a well‐established intracellular pathogen of farmed Atlantic salmon around the world. The bacterium has also been detected from a number of other hosts including lumpfish (Cyclopterus lumpus), seabass (Dicentrarchus labrax) and rainbow trout (Oncorhynchus mykiss).

Monitoring ocean water quality by deployment of lumpfish (Cyclopterus lumpus) eggs: In situ bioaccumulation and toxicity in embryos

Ecotoxicology and Environmental Safety, 2022
Fish embryos can bioaccumulate and are particularly sensitive to a wide range of contaminants, which makes them suitable sentinels for environmental biomonitoring.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, Volume 109, Issue 2, Page 650-692, August 2026.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, Volume 2026, Issue 7, July 2026.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.
