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.

Preliminary multispecies test of a model for non-lethal estimation of metabolic activity in freshwater crayfish

Acta Biologica Slovenica, 2012
We tested the applicability of electron transport system (ETS) derived from a single leg as a tool for non-lethal assessment of metabolicactivity in freshwater crayfish.

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 ...

Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.

Reproductive Interference Alters Species Coexistence in Nematodes due to Asymmetric Sperm‐Induced Harm

Ecology Letters, Volume 28, Issue 1, January 2025.
We test how reproductive interference from inter‐species mating between sympatric Caenorhabditis nematodes can influence species coexistence and exclusion. We demonstrate that females from the species with higher intrinsic population growth experience reduced lifespan and fecundity due to incomplete interspecies mate discrimination that leads to ...

COMPARISON AMONG PRE-GELATINIZED STARCHES OF DIFFERENT BOTANICAL ORIGINS USED IN NOBLE CRAYFISH ASTACUS ASTACUS DIETS

Knowledge and Management of Aquatic Ecosystems, 2006
The objective of the present experiment was to compare the biological value and the binding functionality of four pre-gelatinized starches (wheat, diet 1; waxy maize, diet 2; maize, diet 3 and potato, diet 4) used in crayfish diets.
