Journal of Fish Biology, Volume 109, Issue 3, Page 1360-1378, September 2026.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 ...

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends
Reviews in Aquaculture, Volume 18, Issue 4, September 2026.Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Trace metal distribution in tissues of cichlids (Oreochromis niloticus and O. mossambicus) collected from wastewater-fed fishponds in East Calcutta Wetlands, a Ramsar site [PDF]
Acta Ichthyologica et Piscatoria, 2006 Background. Metals discharged in wastes from different industries into wetland ecosystems pose a serious threat to the receiving environment. Biotic components grown in the area amass such metals within their body through nutritional uptake and ...

Potential mechanism of sound production in Oreochromis niloticus(Cichlidae) [PDF]
Journal of Experimental Biology, 2009 SUMMARY Although acoustic communication is an integral part of cichlid behaviour,its mechanism has never been identified before. In the present study, a combination of approaches was used to investigate the sound-producing mechanism of Oreochromis niloticus. Synchronisation of high-speed video data (500 frames s–1) and cineradiographies (

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Clinostomum complanatum infection is a trematode parasite infecting diverse freshwater fish hosts, causing pathological damage and economic losses. Despite its veterinary and public health importance, its global burden remains insufficiently quantified. This study aimed to assess the global burden of C.

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 ...
