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.

The astacin metalloprotease moulting enzyme NAS-36 is required for normal cuticle ecdysis in free-living and parasitic nematodes [PDF]

, 2011
Nematodes represent one of the most abundant and species-rich groups of animals on the planet, with parasitic species causing chronic, debilitating infections in both livestock and humans worldwide. The prevalence and success of the nematodes is a direct

DEVELOPMENT OF A HABITAT SUITABILITY INDEX FOR THE NOBLE CRAYFISH ASTACUS ASTACUS USING FUZZY MODELLING

Knowledge and Management of Aquatic Ecosystems, 2005
A Geographic Information System (GIS) and fuzzy modelling were used to develop a habitat suitability index for the noble crayfish, Astacus astacus. The model is based on crayfish distribution data for the federal state Hesse, Germany, which had been ...

Farming of the Juvenile Narrow-clawed Crayfish (Astacus leptodactylus) in Cages and Ponds in Polyculture With Fish in the Heated Waste Water of the Thermal Power Plantf [PDF]

, 2010
Experimental research has been carried out on fanning of the narrow-clawed crayfish larvae in ponds and cages in the TPP waste water. It was shown that farming in such conditions during the first vegetation period was more effective, than in water bodies

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 ...
