Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post-mortem. [PDF]

J Sci Food Agric
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.

ON SELECTED MORPHOMECHANICAL CHARACTERISTICS OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS DANA) EGGS DURING INCUBATION

Knowledge and Management of Aquatic Ecosystems, 2004
Changes in resistance to mechanical pressure during embryogenesis were studied in the signal crayfish (Pacifastacus leniusculus Dana). A constant increase in egg size (volume and surface area) was observed to take place throughout the embryonic ...

Beyond Niche Overlap: Axis‐Specific Reorganisation of Environmental Space in Freshwater Crayfish Invasions

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Understanding whether invasive species retain or shift their ecological niches has relied on scalar overlap metrics that quantify the magnitude of niche change but not its structure. Here, we test whether biological invasions involve a reorganisation of the environmental axes along which native and invasive ranges are differentiated, and ...

Advancing Environmental DNA Methods for Monitoring the Reproduction of Quagga and Zebra Mussels in Lakes

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Invasive alien mussels threaten freshwater ecosystems worldwide by disrupting food webs and nutrient cycling. The effective monitoring of these populations is therefore essential to assess their spread and ecological impacts. This study demonstrates the applicability of environmental DNA (eDNA) methods to monitor the reproductive periods of ...

Lectins and cytokines in celomatic invertebrates: two tales with the same end [PDF]

Invertebrate Survival Journal, 2010
The paper presents the principle data regarding the presence and the roles of lectins and cytokines in invertebrates. The former have been described in the main invertebrate taxa, such molluscs, annelids, arthropods, echinoderms and tunicates, while ...

THE DISPERSION OF THE APHANOMYCES ASTACI-CARRIER PACIFASTACUS LENIUSCULUS BY HUMANS REPRESENTS THE MAIN CAUSE OF DISAPPEARANCE OF THE INDIGENOUS CRAYFISH AUSTROPOTAMOBIUS PALLIPES IN NAVARRA

Knowledge and Management of Aquatic Ecosystems, 2006
The tendency of population decline of the indigenous crayfish, Austropotamobius pallipes, in Navarra was reduced by the implementation of a plan of restoration in 1996. Recently, a new drop in population numbers has been noticed.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Host shift to non-native species or ecological dead end? Endangered branchiobdellidans (Annelida: Clitellata) found on introduced Signal Crayfish in Japan

Knowledge and Management of Aquatic Ecosystems
Symbionts, including parasites, are usually small and thus have been overlooked for their existence and scientific research. In the context of biological invasion, host shifts between native and non-native species occur. Since symbionts often affect host

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 ...
