Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Effect of mesh size on baited trap catch composition for noble crayfish (Astacus Astacus)

Knowledge and Management of Aquatic Ecosystems, 2014
Minimum size is a common management regulation in noble crayfish (Astacus astacus) fisheries. The most used catching method baited traps, catch crayfish down to 50 mm total length (TL).

Warming and latitude shape the non-consumptive effects of native and invasive alien crayfish predators on damselfly prey [PDF]

NeoBiota
There is increasing concern that the effects of biological invasions may be magnified by other human-induced global changes. Here, we compare the non-consumptive effects imposed by invasive vs.

Blue plaque review series: Thomas Graham Brown: Before his time

Experimental Physiology, EarlyView.
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

INTERACTION BETWEEN NATIVE AND ALIEN SPECIES OF CRAYFISH IN AUSTRIA: CASE STUDIES

Knowledge and Management of Aquatic Ecosystems, 2002
In Austria, three indigenous crayfish species occur: the noble crayfish (Astacus astacus), the stone crayfish (Austropotamobius torrentium), and the white-clawed crayfish (Austropotamobius pallipes).

Growth performance of Noble Crayfish Astacus astacus in recirculating aquaculture systems [PDF]

Aquaculture International, 2014
There is growing interest in using recirculating aquaculture systems (RAS) to raise noble crayfish Astacus astacus a valuable and once plentiful food species in Europe, now a highly endangered species. The growth and survival of A. astacus was compared in growth trials in RAS and open-pond systems (OPS) over a period of 2 months.

Methods for Improving Settlement and Metamorphosis of Shelled Marine Mollusks in Aquaculture: A Review

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

The Windy City Rookery: Movement and Activity Patterns of Black‐Crowned Night Herons (Nycticorax nycticorax) in a Human‐Dominated Landscape

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Black‐crowned night herons (BCNH) are a cryptic, widely distributed colonial wading bird. Despite showing regional declines in North America, this species has successfully adapted to colonize urban areas. In this study, our team used GPS/GSM transmitters to explore the space use, habitat use, and diel activity patterns of BCNH breeding at the largest ...

Assessing the importance of food for improving noble crayfish culture conditions [PDF]

Knowledge and Management of Aquatic Ecosystems, 2015
Captive breeding and crayfish culture are considered important measures in species protection activities. Thus, knowledge on optimal feeding of crayfish in captivity is needed in order to secure minimal mortality and prevent detrimental effects to health.
