Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry

Fish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.
ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.

Research on the Application of Green Ecological Additive Combinations During the Breeding Period of Redclaw Crayfish

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The three key processes in the breeding of redclaw crayfish are nutrient enhancement by parents, catching and hatching of egg‐holding crayfish and maintaining a feed supply for juveniles. An appropriate combination of green ecological additives is beneficial for improving the production efficiencies of the three key processes.

Genetic diversity of noble crayfish in Finland based on ITS1 microsatellite-like repeat variation: implications to the conservation and management

Knowledge and Management of Aquatic Ecosystems
During the last two centuries, native noble crayfish (Astacus astacus) has been introduced and re-introduced into many waters in Finland, to widen the area of distribution, and to re-establish the collapsed populations.

CRAYFISH OCCURRENCE IN RELATION TO LAND-USE PROPERTIES: IMPLEMENTATION OF A GEOGRAPHIC INFORMATION SYSTEM (GIS)

Knowledge and Management of Aquatic Ecosystems, 2002
On the basis of inventory data collected since 1994, the recent stocking situation for freshwater crayfish in three 10 by 10 km study sites in northeastern Germany (Uckermark) and northwestern Poland (Szczecin area, Koszalin area) is described.

CRAYFISH MANAGEMENT FOR SWISS WATERS

Knowledge and Management of Aquatic Ecosystems, 2006
Seven species of crayfish are present in Swiss waters: three native ones (Astacus astacus, Austropotamobius pallipes, Austropotamobius torrentium) and four exotic ones (Astacus leptodactylus, Orconectes limosus, Pacifastacus leniusculus, Procambarus ...

Chemical changes in the adductor muscle of the cheliped of the crayfish in relation to the double motor innervation [PDF]

, 1938
Work from this laboratory has shown that a number of the striated muscles of the legs of the crayfish show a typical motor innervation (1). Such muscles are innervated by two motor fibers only, each causing a different type of contraction.

Prioritising Non‐Native Crayfish Species for Management in the Rhine‐Main Observatory Using the Dispersal‐Origin‐Status‐Impact (DOSI) Scheme

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Managing non‐native species remains a critical challenge in biodiversity conservation, highlighting the need for effective prioritisation frameworks that integrate ecological, economic and policy considerations. Given that biological invasions are a population‐level rather than a species‐level phenomenon, more nuanced assessment schemes are ...
