Understanding the threats posed by non-native species: public vs. conservation managers. [PDF]

, 2013
Public perception is a key factor influencing current conservation policy. Therefore, it is important to determine the influence of the public, end-users and scientists on the prioritisation of conservation issues and the direct implications for policy ...

Introduced alien signal crayfish (Pacifastacus leniusculus) in Finland − uncontrollable expansion despite numerous crayfisheries strategies [PDF]

Knowledge & Management of Aquatic Ecosystems, 2018
In Finland, massive signal crayfish introductions started towards the end of 1980s, with an estimated total of 2.2 million signal crayfish been stocked before year 2016. During that period, Finnish fisheries authorities have implemented three national management strategies setting guidelines for the crayfish introductions.

Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post‐mortem

Journal of the Science of Food and Agriculture, Volume 105, Issue 10, Page 5163-5172, 15 August 2025.
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.

RELATIONSHIPS BETWEEN CHANGES IN HABITAT CONDITIONS AND POPULATION DENSITY OF AN INTRODUCED POPULATION OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS IN A FLUVIAL SYSTEM.

Knowledge and Management of Aquatic Ecosystems, 2001
After the disappearance of the native crayfish in many rivers in Biscay, Basque Country, Spain, the signal crayfish Pacifastacus leniusculus was introduced in the main fluvial stretches and several breeding populations have established.

Prolonged phenanthrene exposure reduces cardiac function but fails to mount a significant oxidative stress response in the signal crayfish (Pacifastacus leniusculus).

Chemosphere, 2020
Crustaceans are important ecosystem bio-indicators but their response to pollutants such as polyaromatic hydrocarbons (PAHs) remains understudied, particularly in freshwater habitats.
