Comparative study of algal community in African sharptooth catfish (Clarias gariepinus, Burchell 1822) and Nile tilapia (Oreochromis niloticus, Linnaeus 1758) farming ponds

open access: yesAquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 149-164, April 2023., 2023
In the fish farming station, algae specific richness varies according to the water collection point (rearing pond, evacuation canal and decantation pond). Algae contribute differentially to fish diets: biomass is mostly used by Nile Tilapia (herbivorous) than African catfish (omnivorous).

18S rDNA sequence–structure phylogeny of the Euglenophyceae (Euglenozoa, Euglenida)

open access: yesJournal of Eukaryotic Microbiology, Volume 70, Issue 2, March/April 2023., 2023
Abstract The phylogeny of Euglenophyceae (Euglenozoa, Euglenida) has been discussed for decades with new genera being described in the last few years. In this study, we reconstruct a phylogeny using 18S rDNA sequence and structural data simultaneously. Using homology modeling, individual secondary structures were predicted.

A global review of problematic and pathogenic parasites of farmed tilapia

open access: yesReviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Nuclear cytology of Phacus Dujardin.

open access: yesCYTOLOGIA, 1989
Karyological investigations accomplished on sixteen local isolates of Phacus revealed the structure and pattern of mitotic division of nuclei to be atypical. The chromosome numbers ranged from n=10 in P. cylindrus to n=226±8 in P. longicauda, representing the widest range of chromosome numbers reported so far for euglenoid flagellates.

Natural Biota’s Contribution to Cultured Aquatic Animals’ Growth in Aquaculture Cannot Be Ignored

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets.

Evaluation of the Water Quality Status and Pollution Load Carrying Capacity of Way Umpu River, Way Kanan District, Lampung Province, Indonesia, Based on Land Use

open access: yesInternational Journal of Ecology, Volume 2023, Issue 1, 2023., 2023
This research aims to evaluate the water quality status and pollution load‐carrying capacity of the Way Umpu River based on land use. This was carried out using the survey method by directly measuring the river water debit, pH, temperature, and dissolved oxygen (DO) on‐site, taking the water sample to analyze the parameters of water quality such as ...

Food niches of planktonic rotifers: Diversification and implications

open access: yesLimnology and Oceanography, Volume 67, Issue 10, Page 2218-2251, October 2022., 2022
Abstract The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations and experiments. Also considered are methodological approaches, rotifer feeding mechanisms, and the availability in natural waters of less well‐known food items (detritus, picoplankton, protozoans).

Some new and rare Euglenophyce from the State of São Paulo, southern Brazil Algumas novas e raras Euglenophyceae no Estado de São Paulo, Sul do Brasil

open access: yesActa Botânica Brasílica, 1987
Occurrence is reported from the region of the city of São Paulo, southern Brazil, of two euglenoid flagellates (Euglenophyceae). These are very rare, and thus very poorly known members of the class: Scytomonas major (Berliner) Lemmermann and Scytomonas ...
