Overview of the discus fish (Symphysodon spp.): narrative review combined with potential for ornamental aquaculture

Brazilian Journal of Biology
The discus fish (Symphysodon spp.) is an Amazonian cichlid species with great appeal in the ornamental fish market due to its characteristic shape, coloration, and behavior. This study aims to conduct a narrative review of the discus fish.

Morphological Evidence for Functional Crosstalk Between Multiple GnRH Systems in the Male Tilapia, Oreochromis niloticus

Frontiers in Endocrinology, 2020
Gonadotropin-releasing hormone (GnRH) is a reproductive neuropeptide, which controls vertebrate reproduction. In most vertebrates, there are more than two GnRH orthologs in the brain.

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

East African cichlid lineages (Teleostei: Cichlidae) might be older than their ancient host lakes: new divergence estimates for the east African cichlid radiation

BMC Evolutionary Biology, 2019
Background Cichlids are a prime model system in evolutionary research and several of the most prominent examples of adaptive radiations are found in the East African Lakes Tanganyika, Malawi and Victoria, all part of the East African cichlid radiation ...

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Individual variation in male mating preferences for female coloration in a polymorphic cichlid fish [PDF]

, 2008
Female color polymorphisms are common in the cichlid species radiations of Lake Victoria and Lake Malawi. According to theory, when a population harbors variation in sex-determining factors, polymorphism in female-linked coloration might generate ...

Larval Development of Rusty Cichlid Fish (Iodotropheus sprengerae Oliver & Loiselle, 1972): Morphological Observations

Acta Natura et Scientia, 2022
This study aimed to describe the larval development stage of rusty cichlid, Iodotropheus sprengerae morphologically. The rusty cichlid is a mouth-brooding haplochromine cichlid from Lake Malawi.

A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled
