Reproductive plasticity of a Procambarus clarkii population living 10\ub0C below its thermal optimum [PDF]

, 2015
In this study the annual reproductive biology of a Procambarus clarkii (Girard, 1852) population living in an atypical habitat with cold spring waters is investigated by monitoring Gonado-Somatic and Hepato-Somatic Indexes (GSI and HSI) and by performing

Arsenic Uptake and Depuration by Red Swamp Crayfish, Procambarus clarkii

Journal of Anatolian Environmental and Animal Sciences, 2019
Paddy rice soils, which can contain elevated levels of arsenic, also have importance in crayfish production in Louisiana (USA). In this study, arsenic accumulation and depuration in the tissues of crayfish (Procamborus clarkii) exposed to different As concentrations were determined.

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Redclaw Crayfish: Challenge or Resource? Voices of Fishers in Zambia

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Invasive species severely threaten biodiversity, ecosystem stability and local livelihoods, especially in vulnerable areas. Therefore, understanding community perceptions is vital for creating effective and inclusive management strategies. This study investigated perceived environmental and economic impacts of the invasive, Redclaw crayfish ...

Movement and interaction of two exotic crayfish (Pacifastacus leniusculus and Procambarus clarkii) using PIT telemetry in experimental conditions [PDF]

, 2009
The coexistence of two exotic crayfish species (Procambarus clarkii and Pacifastacus leniusculus) was observed in a stretch of Rio Maçãs (Douro basin, Northeast of Portugal). The red swamp crayfish, P.

Assessing the context‐dependence of invasiveness in the Italian wall lizard (Podarcis siculus)

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Although the Italian wall lizard (Podarcis siculus) is widely considered fully invasive, our study on Gorgona Island shows its spread is largely confined to human‐altered habitats. Native common wall lizards (P. muralis) persist in natural areas, indicating that Italian wall lizard invasiveness is context‐dependent and mediated by human‐altered ...

The Combined Effects of Multiple Invasive Species on Persistence of Imperiled Pahrump Poolfish

Fishes
Many ecosystems have been invaded by more than one non-native species, but research evaluating the combined effects of multiple invasive species has been limited.

Mechanical excavation of wetland habitat failed to eradicate invasive American red swamp crayfish (Procambarus clarkii) in Malta

Ecological Solutions and Evidence
Invasive crayfish are an important ecological concern in many freshwater ecosystems. Many efforts have been made to eradicate them, but there is very little documentation of the effectiveness of these efforts.

BIOECONOMIC MANAGEMENT OF RED SWAMP CRAYFISH (PROCAMBARUS CLARKII) IN THE PRESENCE OF ENVIRONMENTAL EXTERNALITIES [PDF]

Red swamp crayfish (Procambarus clarkii) is a valuable renewable resource which creates significant negative externalities to its environment. Crayfish can cause severe crop damage by burrowing in fields and using irrigation systems to spread.
