Biological control of Biomphalaria tenagophila (Mollusca, Planorbidae), a schistosomiasis vector, using the fish Geophagus brasiliensis (Pisces, Cichlidae) in the laboratory or in a seminatural environment

open access: yesMemorias do Instituto Oswaldo Cruz, 1990
In order to investigate a possible method of biological control of schistosomiasis, we used the fish Geophagus brasiliensis (Quoy & Gaimard, 1824) which is widely distributed throughout Brazil, to interrupt the life cycle of the snail Biomphalaria ...

Eugenol and tricaine methanesulfonate as anhestesics for the pearl cichlid

open access: yesActa Scientiarum: Biological Sciences, 2021
Anesthesia reduces the handling process duration and prevent fish injuries. The anesthetic effect and ideal concentrations of eugenol and tricaine methanesulfonate (MS-222) were tested for pearl cichlid (Geophagus brasiliensis) juveniles with an average

Biliary and hepatic metallothionein, metals and trace elements in environmentally exposed neotropical cichlids Geophagus brasiliensis [PDF]

open access: yesJournal of Trace Elements in Medicine and Biology, 2018
One of the metal detoxifying mechanisms that occurs in fish is metallothionein (MT) induction and metal binding. Hepatic MT induction has been well described, but biliary MT metal detoxification has only recently been described in fish. In this scenario, metal-metal interactions have been increasingly evaluated to further understand the behavior of ...

Geophagus brasiliensis (Teleostei: Cichlidae) as an indicator of toxicity of ornamental stone processing wastes

open access: yesComparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2019
Massive exploitation of geological resources may lead to environmental issues due to the inadequate disposal of the processing wastes, which are potentially hazard to terrestrial and aquatic environments. To evaluate the toxic effects ornamental stones processing wastes (OSPW), Geophagus brasiliensis fish were contaminated with different concentrations

Metals in Fishes from Yongshu Island, Southern South China Sea: Human Health Risk Assessment

open access: yesJournal of Toxicology, Volume 2017, Issue 1, 2017., 2017
In order to assess the bioaccumulation of metals associated with gender, tissues, and their potential ecological risk, four species of fish were collected from the Yongshu Island in the Southern South China Sea. Metals and stable Pb isotopes in their tissues (muscle, gill, liver, intestine, and ovary) were determined.

Paralytic shellfish toxins and ocean warming: bioaccumulation and ecotoxicological responses in jujvenile Gilthead Seabream (Sparus aurata) [PDF]

open access: yes, 2019
Warmer seawater temperatures are expected to increase harmful algal blooms (HABs) occurrence, intensity, and distribution. Yet, the potential interactions between abiotic stressors and HABs are still poorly understood from ecological and seafood safety ...

Illuminating the Dark: Using eDNA Metabarcoding to Study the Unique Ichthyofauna of the Furnas Formation Sinkholes

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.
