‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing

Journal of Fish Biology, EarlyView.
Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...

Polyculture of European seabass and Nile tilapia in the recirculating aquaculture system with brackish water: Effects on the growth performance, feed utilization, and health status

Aquaculture and Fisheries
Non-traditional aquaculture practices are crucially needed to overcome the climate change consequences, especially in countries suffering from water shortages.

Methylation pattern polymorphism of cyp19a in Nile tilapia and hybrids

Open Life Sciences, 2018
AbstractSkewed sex development is prevalent in fish hybrids. However, the histological observation and molecular mechanisms remain elusive. In this study, we showed that the interspecific hybrids of the two fish species,Oreochromis niloticusandOreochromis aureus, had a male ratio of 98.02%.

Acute Hypoxia–Reperfusion Triggers Immunocompromise in Nile Tilapia [PDF]

Journal of Aquatic Animal Health, 2007
Abstract Inadequate dissolved oxygen in the aquatic environment is a well-established cause of fish morbidity and mortality. The specific effects of hypoxia on immune function in fish, however, are not well characterized. In this study, the effects of acute hypoxia followed by reoxygenation (rapid tissue reperfusion) as a source of ...

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

Journal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

Non-Additive and Asymmetric Allelic Expression of p38 mapk in Hybrid Tilapia (Oreochromis niloticus ♀ × O. aureus ♂)

Animals
Hybridization is a widely used breeding technique in fish species that enhances desirable traits in cultured species through heterosis. However, the mechanism by which hybrids alter gene expression to form heterosis remains unclear.

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.
