Development and Assessment of Fluorescent‐Dyed, Preserved Invasive Grass Carp (Ctenopharyngodon idella) Eggs as Surrogates for Live Eggs in Transport and Dispersal Control Experiments

River Research and Applications, Volume 42, Issue 5, Page 976-988, June 2026.
ABSTRACT Invasive species such as grass carp ( Ctenopharyngodon idella ) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

The Recovery of Predators Modulates Prey Community Organization Through Concomitant Changes in Aquatic Trophic Networks

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Restoring predator populations can generate cascading effects on their prey by reshaping ecosystem food webs, yet its consequences for prey community organization and multi‐trophic dynamics remain poorly understood. We aimed to evaluate how native predator recovery shapes prey biodiversity, assembly processes, and trophic dependencies, and

Environmental DNA Reveals Major Shifts in Fish and Amphibian Diversity and Distribution in Alpine Lentic Ecosystems of Southwest China, Supporting Improved Conservation and Management

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Alpine lentic ecosystems are naturally fish‐poor or fish‐free, yet they have received numerous non‐native fish introductions globally. Studies have demonstrated that alien fish have negative impacts on aquatic organisms, particularly amphibians, which are highly susceptible to habitat alterations.

Molecular characterization of CCKR in Ctenopharyngodon idella and its involvement in the intestinal immune response to bacterial challenges

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Cholecystokinin receptor (CCKR), an important recognition receptor for the gastrointestinal hormone cholecystokinin (CCK) in the endocrine system, plays a crucial role in regulating immune responses in mammals. In this study, a novel cholecystokinin receptor (CiCCKR) was identified from the grass carp Ctenopharyngodon idella.

Integrating curimba culture during the grow‐out phase of tambaqui affects overall productivity, water quality, and fish health

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract The efficiency of feed use in aquaculture may be improved by integrating the culture of extractive species into fed‐species systems. This study assessed the impact of including curimba (Prochilodus lineatus) in tambaqui (Colossoma macropomum) production during the grow‐out phase in earthen ponds.

Effects of farming practices on the performance of fish pond polyculture assessed by trophic modeling

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract This study aimed to identify species compositions that use resources more efficiently and recommend management practices for extensive and semi‐intensive pond polyculture by modeling food webs and calculating performance indicators. We monitored 8 polyculture fish ponds managed by fish farmers that had contrasting fish species compositions in ...
