Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya

American Anthropologist, Volume 128, Issue 1, Page 183-194, March 2026.
ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

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‐

River Connectivity in Dammed Areas Studied Through Environmental DNA Metabarcoding at Community and Species Levels

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The field of environmental DNA (eDNA) is rapidly expanding with established applications in biodiversity monitoring, rare species detection and ecological assessment. However, its potential to evaluate species connectivity in fragmented aquatic systems remains underexplored.

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 ...

Land use, associated eel production, and abundance of fish and crayfish in streams in Waikato, New Zealand [PDF]

, 1997
The density and biomass of fish and crayfish, and the production of eels, was compared among streams in native forest, exotic forest, and pasture. Populations were estimated by multiple-pass electroshocking at 11 sites in hill-country streams in the ...
