Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post‐mortem

Journal of the Science of Food and Agriculture, Volume 105, Issue 10, Page 5163-5172, 15 August 2025.
Abstract Evaluating protein and mitochondrial alterations post‐mortem can contribute to determining correlations between fish‐processing parameters and ultimate fish muscle quality. The myofibrillar protein alteration during rigor mortis directly affects the texture of fish muscle.

Escape rooms: behavioural response of two invasive crayfish species under water decline scenarios

Journal of Limnology
Climate change and invasive alien species pose a significant threat to biodiversity and the survival of native species. This study considered the impact of drought conditions on the escape behaviour through terrestrial dispersal ability of two invasive ...

A STUDY ON THE POSSIBLE EFFECT OF TWO CRAYFISH SPECIES ON EPILITHIC ALGAE IN A MOUNTAIN STREAM FROM CENTRAL SPAIN

Knowledge and Management of Aquatic Ecosystems, 2006
The effects on epilithic algae of increasing densities of two crayfish species, Austropotamobius italicus and Pacifastacus leniusculus, the latter recently introduced in Spain, have been monitored using riverine enclosures, within a large experimental ...

Predatory impacts of alien decapod Crustacea are predicted by functional responses and explained by differences in metabolic rate

, 2018
Alien predators can have large impacts on prey. It is important that we understand, and ideally predict, these impacts. Here, we compare predatory impacts of size-matched decapod crustaceans—invasive alien Eriocheir sinensis and Pacifastacus leniusculus,

Invasive crayfish impacts on native fish diet and growth vary with fish life stage [PDF]

, 2016
Assessing the impacts of invasive organisms is a major challenge in ecology. Some widespread invasive species such as crayfish are potential competitors and reciprocal predators of ecologically and recreationally important native fish species.

Synergies Between Anthropogenic Litter and Biopollution in SW Bay of Biscay Rivers Discovered Through Citizen Science: Implications for Conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.
ABSTRACT Anthropogenic litter and other pollutants are known to contribute to the introduction and settlement of invasive alien species (IAS) in marine settings; however, the relationship between biopollutant IAS and litter in rivers is much less studied.

EXTENSION D’UNE ESPÈCE ENVAHISSANTE : SUIVI DE LA POPULATION D’ÉCREVISSES SIGNAL (PACIFASTACUS LENIUSCULUS DANA) AU LÉMAN À L’OUEST DE THONON-LES-BAINS, ENTRE 2001 ET 2005 – IMPACT DE LA PÊCHE

Knowledge and Management of Aquatic Ecosystems, 2006
La population d’écrevisses signal arrivées en 1976 dans le Léman continue son expansion le long de la zone littorale à l’ouest de Thonon-les-Bains. En 2001, la population s’étendait jusqu’à Séchex avec une forte densité (82 indiv./nasse) de Thonon à ...

Technical challenges in the implementation of macroinvertebrate DNA metabarcoding in river biomonitoring: A case study from peninsular Spain—Advantages, limitations and roadmap

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
This study evaluates the opportunities and challenges of using DNA metabarcoding of river macroinvertebrates for routine ecological status assessment under the EU Water Framework Directive. By reanalysing data from rivers in north‐west Spain, it identifies key sources of false positives and negatives, compares bulk and eDNA sampling with traditional ...

DISTRIBUTION OF INDIGENOUS AND NON-INDIGENOUS CRAYFISH POPULATIONS IN THE POITOU-CHARENTES REGION (FRANCE): EVOLUTION OVER THE PAST 25 YEARS

Knowledge and Management of Aquatic Ecosystems, 2006
Subsequent surveys carried out from 1978 to 2003 demonstrated a high disappearance of Austropotamobius pallipes populations from the region and the alarming spread of non-indigenous species like Procambarus clarkii and Pacifastacus leniusculus ...
