Swim bladder as a primary site of mycobacterial infection in Nothobranchius ‘belly sliders’ I. Dyková, J. Žák, M. Reichard , K. Součková, O. Slabý, R. Blažek ABSTRACT: The swim bladder inflates early after fish hatching via its interconnection with the digestive tract (ductus pneumaticus). This interconnection may serve as a portal to foreign particles, including bacteria, causing deficiencies in primary swim bladder inflation. We histologicallyexamined 134 African annual killifish (genus Nothobranchius) with secondary loss of swim bladder function (‘belly sliders’)….

Santos, Luciano Medeiros de Araujo, Angélica da Silva Vasconcellos, Ronald Kennedy LuzFirst published: 04 June 2021 https://doi.org/10.1111/are.15365 Abstract This work aimed to evaluate two types of substrate for egg production by annual killifish (Hypsolebias flagellatus) and to describe the reproductive behaviour of males and females. Experiment I, with two phases, tested two types of substrates: coconut shell powder (CP) and brown 100% acrylic wool (AW), with five male–female…

AbstractAphanius fasciatus is a small fish occurring in Mediterranean brackish environments. In Cyprus it is known from three localities separated by long stretches of coast. The genetic diversity of these populations was evaluated using fragments of two mitochondrial genes. A comparison with the other available data showed that Cyprus populations represent a distinct lineage. The other lineages are concentrated in a relatively small area between the Strait of Sicily and the Western…

Discovered over 20 years ago but only recently described by science. Nothobranchius attenboroughi could become a flagshipspecies for the epic landscape of the Serengeti.
“A heroic undertaking in its scope. The icthyological community has eagerly awaited the publication of the second volume of this most important work, which provides continent-wide coverage of North America’s freshwater fish fauna. This book will make our jobs easier.”– Tim M. Berra, Ohio State University
