L-carnitine can promote the growth performance of rotifers (Brachionus rotundiformis) by improving their feeding behavior and nutrient composition

open access: yesAquaculture Reports
Rotifer are important food resources in aquaculture hatcheries, and several studies have shown that L-carnitine (LC) can promote the growth performance of rotifers.

The Impact of Two Different Cold-Extruded Feeds and Feeding Regimens on Zebrafish Survival, Growth and Reproductive Performance

open access: yesJournal of Developmental Biology, 2018
Zebrafish (Danio rerio) is one of the top model organisms used in biomedical research. Therefore, it is fundamental that zebrafish facilities continuously improve husbandry methods to provide fish with the best physiological and welfare conditions that ...

La controverse Doyère-Pouchet sur la reviviscence animale et ses échos dans L’Homme à l’oreille casséed’Edmond About

open access: yesStudia Romanica Posnaniensia, 2020
Rotifers and tardigrades, microscopic animals discovered in the 18th century, have exceptional abilities to survive in hostile conditions. Exposing them to desiccation, extreme temperatures, and vacuum, scientists wanted to determine whether ...

An ecological study of Rotifera of the Southern Shatt Al-Arab River, Basrah, Iraq

open access: yesالمجلة العراقية للاستزراع المائي, 2022
At three stations of the Shatt Al-Arab River, the ecology of Rotifera was studied: the first Al-Ashar second Abul Khasib and the third Al-Fao. Seasonal horizontal hauls were taken by a plankton net of a mesh-size of 53-µm during 2013. Density of Rotifera

Growth and toxicity of Halomicronema metazoicum (Cyanoprokaryota, Cyanophyta) at different conditions of light, salinity and temperature

open access: yesBiology Open, 2019
Cyanobacteria may live in the water column and in the benthos of aquatic environments, or be symbionts of other organisms, as in the case of Phormidium-like cyanobacteria, known to influence the ecology of freshwater and marine ecosystems.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Pikeperch larviculture (Sander lucioperca [L., 1758]) with Brachionus plicatilis (Mueller, 1786) (Rotifera) and Apocyclops panamensis (Marsh, 1913) (Copepoda)

open access: yesJournal of the World Aquaculture Society, 2023
The effect of live feed diets containing Brachionus plicatilis (B) and Apocyclops panamensis (A) was investigated on pikeperch larval survival, growth, and fatty acid composition in two experiments (E1 and E2).

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Content in nine minerals and seven vitamins of rotifers (Brachionus plicatilis) fed commercial diets and two forms of Nannochloropsis oculata

open access: yesJournal of the World Aquaculture Society
The objective of the present study was to determine the effects of spray‐dried and fresh forms of the microalgae Nannochloropsis oculata and other commonly used commercial diets on vitamin and mineral compositions of rotifer produced under commercial ...
