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.

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

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

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

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

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.

Photoperiod modulates male sexual maturation in the Emperor tetra (Nematobrycon palmeri), a strictly tropical ornamental fish

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.

Biocontrol for Shrimp Disease: Comprehensive Review and a Bacterial Disease Biocontrol Practice

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Biocontrol is a key strategy for disease control, as it is environmentally friendly and widely applicable. This review elaborates on biocontrol in aquaculture, particularly in shrimp culture. Biocontrol in shrimp culture mainly relies on four strategies: (i) direct kill pathogen by Bdellovibrio or bacteriophages; (ii) suppression of intestinal
