Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Length‐Weight Relationships of Sixteen Fish Species From the Upper Tietê Basin, Southeaster Brazil

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
This study investigated the length‐weight relationship (LWR) of 16 fish species from the Upper Tietê Basin under the influence of the Atlantic Forest biome, aiming to provide updated morphometric data and contribute to the knowledge of Neotropical ichthyofauna. 2811 specimens were collected and distributed across five orders and 10 families.

The problems with pin bones: Intermuscular bone development and function in salmonids and their implications for aquaculture

Reviews in Aquaculture, Volume 16, Issue 4, Page 1981-1995, September 2024.
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.

Continuous tooth replacement: what can teleost fish teach us?

Biological Reviews, Volume 99, Issue 3, Page 797-819, June 2024.
ABSTRACT Most tooth‐bearing non‐mammalian vertebrates have the capacity to replace their teeth throughout life. This capacity was lost in mammals, which replace their teeth only once at most. Not surprisingly, continuous tooth replacement has attracted much attention. Classical morphological studies (e.g.

A new characid species with remarkable sexual dimorphism (Characiformes: Characidae: Stevardiinae) from the upper Guayabero River, Orinoco basin, Colombia

Journal of Fish Biology, Volume 104, Issue 6, Page 1947-1959, June 2024.
Abstract A new species of characid with remarkable sexual characteristics is described from the upper Guayabero River drainage from the Orinoco basin in Colombia. The new species is included in the genus Monotocheirodon by sharing most of the previously proposed diagnostic features of this genus.
