Impact and fracture analysis of fish scales from Arapaima gigas

Materials Science and Engineering: C, 2015
Fish scales from the Amazonian fish Arapaima gigas have been characterised to study their impact and fracture behaviour at three different environmental conditions. Scales were cut in two different directions to analyse the influence of the orientation of collagen layers.

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Evidence of polygamy in the socially monogamous Amazonian fish Arapaima gigas (Schinz, 1822) (Osteoglossiformes, Arapaimidae)

Neotropical Ichthyology
Arapaima gigas is one of the largest freshwater fishes of the world. It is socially monogamous, forming pairs, constructing a nest and providing parental care.

Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

Superworm‐Derived Protein Hydrolysate: Functional Properties and Activity Following Enzymatic Processing

Journal of Food Process Engineering, Volume 49, Issue 6, June 2026.
Protein hydrolysate was successfully developed from defatted Zophobas morio flour. The pepsin hydrolysate exhibited superior properties compared to Brauzyn. The hydrolysis process with pepsin achieved a notable hydrolysis degree and yield. Pepsin hydrolysate from Z. morio showed high protein content and solubility.
