Design and Validation of a Single‐Species Environmental DNA qPCR Assay for the Detection of the Invasive Chinese Mitten Crab Eriocheir sinensis

Environmental DNA, Volume 7, Issue 5, September–October 2025.
The Chinese mitten crab (Eriocheir sinensis) is considered amongst the most damaging invasive species globally; however, the UK distribution of the species is not well known, with current management protocols reliant on reports of individual sightings. In this study, the first probe‐based, species‐specific qPCR assay was developed for the detection of ...

Non‐Invasive Monitoring of Tetracapsuloides bryosalmonae by eDNA: Influencing Environmental Parameters

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated influencing environmental factors on a previously developed eDNA‐based detection protocol for T. bryosalmonae. Specifically, water and air temperature, precipitation as well as bryozon presence and infection status were evaluated. Recommendations for a future eDNA‐based monitoring of T. bryosalmonae are provided.

The Future of Pathogen Detection in Aquaculture: Miniature Labs, Field‐Compatible Assays, environmental DNA and RNA, CRISPR and Metatranscriptomics

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Inland recirculating aquaculture is a thriving food industry providing sustainable and locally sourced high‐quality protein. However, its expansion is accompanied by emerging challenges regarding the spread of pathogens and diseases. Detection and management of pathogens in aquaculture remain underdeveloped compared to other animal farming ...

Practical disinfection chemicals for fishing and crayfishing gear against crayfish plague transfer

Knowledge and Management of Aquatic Ecosystems, 2014
We tested four commercial disinfectants against crayfish plague (Aphanomyces astaci) spores in both aquatic solutions and with material mimicking fishing and crayfishing gear, e.g. traps, ropes, mesh, etc.

Non‐Native Species in Aquaculture: Burgeoning Production and Environmental Sustainability Risks

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Rising global food demands and technological advancements have led to unprecedented growth in the aquaculture industry. This rapid expansion has facilitated the translocation of species beyond their native ranges. While farming non‐native species boosts global food supply, it also poses environmental and socio‐economic risks when escapees ...

DISTRIBUTION AND REPRODUCTIVE BIOLOGY OF AUSTROPOTAMOBIUS TORRENTIUM IN BAVARIA AND DOCUMENTATION OF A CONTACT ZONE WITH THE ALIEN CRAYFISH PACIFASTACUS LENIUSCULUS

Knowledge and Management of Aquatic Ecosystems, 2005
In Bavarian freshwater systems, the stone crayfish Austropotamobius torrentium is still present in many headwaters of Danubian tributaries. Since the 1960s an alien species, the signal crayfish Pacifastacus leniusculus, was introduced several times ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.
