Journal of Fish Biology, EarlyView.Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands
Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, Volume 309, Issue 9, Page 2286-2297, September 2026.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT In Namibia, the aquaculture sector faces significant challenges, mainly due to the high cost of imported commercial feed, which limits small‐scale farmers' productivity and food security. To address this, locally formulated feeds must be evaluated as sustainable alternatives.

Convict cichlids benefit from close proximity to another species of cichlid fish [PDF]
Biology Letters, 2008 The coexistence of species with overlapping resource use is often thought to involve only negative fitness effects as a consequence of interspecific competition. Furthermore, the scarce empirical research on positive species interactions has predominantly focused on sessile organisms.

Metabolic adjustments in Satanoperca aff. jurupari (Perciformes: Cichlidae)
Genetics and Molecular Biology, 2003 In this paper, we describe the enzyme levels and isozyme distribution in skeletal and heart muscle of Satanoperca aff. jurupari, (Cichlidae, subgroup Geophaginae). LDH and CS were measured in skeletal and heart muscle. Starch gel electrophoresis was used

Assessment of Small‐Meshed Gillnets for Sustainable Fisheries in the Chobe River, Namibia
Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Small‐meshed gillnets are restricted by the regulatory framework of the Namibian Inland Fisheries Act of 2003. This is mainly because smaller meshed nets are presumably selective towards juveniles of the large‐growing cichlid species. Thus, the aim of this study was to assess the impacts of smaller meshed gillnets (<73 mm) on the fish stocks ...

Cichlids: A Host of Opportunities for Evolutionary Parasitology
Trends in Parasitology, 2016 Thanks to high species diversity and a broad range of speciation mechanisms, cichlid fishes represent a textbook model in evolutionary biology. They are also of substantial economic value. Despite this importance, cichlid parasites remain understudied, although some are more diverse than their hosts.
