Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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 ...

HAEMATOLOGICAL VALUES OF PAICHE ARAPAIMA GIGAS IN THE PERUVIAN AMAZONIA

Revista de Investigaciones Veterinarias del Perú, 2013
Haematological values of paiche, Arapaima gigas, were determined in 120 blood samples collected from May 2009 to January 2011. The fishes were cultivated in two fish farms located in the province of Maynas, Loreto, Peru. Blood samples were classified according to four age groups: 10-30, 31-180, 181-365 and >365 days.

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.
