From Chromosomes to Genome: Insights into the Evolutionary Relationships and Biogeography of Old World Knifefishes (Notopteridae; Osteoglossiformes). [PDF]
In addition to its wide geographical distribution, osteoglossiform fishes represent one of the most ancient freshwater teleost lineages; making it an important group for systematic and evolutionary studies. These fishes had a Gondwanan origin and their past distribution may have contributed to the diversity present in this group.

Abstract Aim Substantial progress has been made to map biodiversity and its drivers across the planet at multiple scales, yet studies that quantify the evolutionary processes that underpin this biodiversity, and test their drivers at multiple scales, are comparatively rare.

Review of Magnetic Shark Deterrents: Hypothetical Mechanisms and Evidence for Selectivity
Several papers published since 2006 describe effects of magnetic fields on elasmobranchs and assess their utility in reducing negative interactions between sharks and humans, including bycatch reduction.

Abstract A healthy skeletal system is fundamental to fish welfare and performance and a key physiological feature of a robust fish. The presence of skeletal deformities in farmed salmonids is a persistent welfare problem in aquaculture, and one which threatens to impede industry growth.

Fish diversity and assemblages according to distance from source along a coastal river gradient (Ehania River south-east of Ivory Coast) [PDF]
Fish assemblage was investigated during the study of longitudinal profile of the Ehania River Basin in south-eastern Côte d’Ivoire. This area is subjected to intense human activities with many plantations (palm tree, banana, pineapple, coffee, rubber and

The Asian arowana (Scleropages formosus) genome provides new insights into the evolution of an early lineage of teleosts [PDF]
The Asian arowana (Scleropages formosus), one of the world’s most expensive cultivated ornamental fishes, is an endangered species. It represents an ancient lineage of teleosts: the Osteoglossomorpha.

The fish species are identified primarily based on their morphological and meristic characters and of late, the molecular markers too have been used for differentiating between different genera and species. Scale morphology and structure has been established as a tool in fish taxonomy.

A review of the reproductive biology of mormyroid fishes: An emerging model for biomedical research
Mormyroid electric fish have great potential as biomedical models, but the inability to reliably breed mormyroids in the laboratory has hindered widespread use in this capacity. To facilitate solving this problem, we extensively review mormyroid reproductive biology.
