The Aggregation of Fish in the Metalimnion Constrains Zooplankton Diel Vertical Migration

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The role of fish predation in zooplankton diel vertical migration (DVM) is well established, where zooplankton move to deep waters during the day—to hide from visual predators in surface layers—and return to the epilimnion at night (i.e., ‘normal’ DVM), to feed on phytoplankton.

Variation of cladocerans from Maoping to Guizhou in the Three Gorges Reservoir before and after impoundment

open access: yes, 2006
The Three Gorges Reservoir was filled at 1 june., 2003. The water level of the reservoir rose up to 135m. The lotic river ecosystem evolved into relative lentic reservoir ecosystem before the dam.

Widespread Aquatic Insect Responses to Recent Warming in Swiss Mountain Lakes

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Chironomids in surface sediment from 24 Swiss mountain lakes were studied and compared with surveys conducted on the same lakes in 1993/2002 to assess biological responses to recent climate warming. Most lakes show significant shifts in this important group of aquatic insects towards assemblages typical of warmer conditions, while a subset exhibits ...

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

open access: yesJournal 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

open access: yesJournal 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 ...
