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 ...

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.

Implications for Osmorespiratory Compromise by Anatomical Remodeling in the Gills of Arapaima gigas [PDF]
The Anatomical Record, 2013 ABSTRACTThe gill structure of the Amazonian fish Arapaima gigas, an obligatory air breather, was investigated during its transition from water breathing to the obligatory air breathing modes of respiration. The gill structure of A. gigas larvae is similar to that of most teleost fish; however, the morphology of the gills changes as the fish grow.

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.

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.ABSTRACT Monogeneans are among the most problematic ectoparasites in finfish aquaculture. Plant‐derived compounds have been widely explored as therapeutic agents, yet their efficacy and safety have not been quantitatively synthesized across studies. This study provides a meta‐analysis of plant‐based treatments against monogeneans, integrating 453 in ...
