Amazonian drought of 2023: Environmental conditions relevant to fishes

Journal of Fish Biology, EarlyView.
Abstract This paper provides a platform for the following studies within this Special Issue. ‘Ecophysiology of fishes in the two great tributaries of the Amazon in the Anthropocene’. It documents the water quality conditions and accompanying zooplankton community structure and biomass relative to fish health in the Rio Negro and Rio Solimões during the

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Propagation method and species drive survival patterns across reef zones in coral seeding on the Great Barrier Reef

Restoration Ecology, EarlyView.
Abstract Introduction Coral reef restoration increasingly relies on scalable methods, yet outcomes vary across species, propagation techniques, and habitats. Coral seeding, where coral propagules are settled on deployment units before outplanting, provides a flexible approach that accommodates both asexual (e.g. microfragments) and sexual (e.g.

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Special issue in honour of Prof. Reto J. Strasser - Efficacy of botanical pesticide for rotifer extermination during the cultivation of Nannochloropsis oculata probed by chlorophyll a fluorescence transient

Photosynthetica, 2020
Nannochloropsis is widely used in aquaculture as a feed source. However, large-scale cultivation of Nannochloropsis usually fails due to rotifer contamination.

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Nutritional effect of three microalgae and one cyanobacteria on the culture of the rotifer Brachionus plicatilis Müller: 1786

Ciencias Marinas, 1996
Three microalgae and one dehydrated cyanobacteria were tested to determine the best concen­tration and the best food for the culture of a local strain of the rotifer Brachionus plicatilis type L. The observations were: density of rotifers, fecundity and

Husbandry of Newly Born Endangered White's Seahorse, Hippocampus whitei, for Conservation Stocking

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Conservation stocking programmes have been increasingly used to reverse wildlife population declines; however, the success of such programmes can often depend on the number and fitness of animals translocated or released. The White's seahorse Hippocampus whitei is an endangered seahorse species endemic to eastern Australia, where a ...
