Interactions between invasive crayfish and native river shrimp

Knowledge and Management of Aquatic Ecosystems, 2011
In the south of Portugal there are only two species of strictly freshwater decapods: the native freshwater shrimp Atyaephyra desmarestii and the exotic crayfish Procambarus clarkii. The aim of this study is to understand if the

Crayfish: A Culture Species for Freshwater Bodies

Bhartiya Krishi Anusandhan Patrika, 2020
Crayfish, commonly known as freshwater lobster, have been scientifically distributed in three genuses, which are as follows: - Cumberfish, Oronectes and Phalisaberus. Crayfish breeding and rearing techniques in China and some Adapted and practiced in South-East Asian countries. The proper ratio of broodstock female and male is 3: 1.

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, Volume 33, Issue 4, Page 694-705, August 2026.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, Volume 33, Issue 4, Page 633-645, August 2026.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

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 ...

Integrated histopathological, physiological, biochemical, and molecular analysis of gill responses to acute salinity stress in red tilapia (Oreochromis spp.)

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Growing freshwater scarcity in China is driving aquaculture interests toward saline‐tolerant fish species. Red tilapia (Oreochromis spp.) is a euryhaline species with strong osmoregulatory capacity, making it an ideal model for investigating stress‐induced physiological changes.

Newly discovered diversity within European branchiobdellids – a story of co-evolution and a need for conservation

Knowledge and Management of Aquatic Ecosystems
Branchiobdellids are small ectosymbiotic annelids living primarily on freshwater crayfish. Because humans frequently translocate crayfish, these symbionts can be co-translocated, with implications for biosecurity and conservation.

SPECIES OF BRANCHIOBDELLIDAE (ANNELIDA) ON FRESHWATER CRAYFISH IN SOUTH TYROL (NORTHERN ITALY)

Knowledge and Management of Aquatic Ecosystems, 2002
Twenty-eight freshwater crayfish were collected from 8 streams and one small lake in the province of South Tyrol (North Italy) from autumn 1999 to spring 2001, in order to investigate the presence of branchiobdellidans.
