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.

Heart structure in the Amazonian teleost Arapaima gigas (Osteoglossiformes, Arapaimidae) [PDF]

Journal of Anatomy, 2018
AbstractThe fish heart ventricle has varied morphology and may have a specific morpho‐functional design in species adapted to extreme environmental conditions. In general, the Amazonian ichthyofauna undergoes constant variations in water temperature, pH and oxygen saturation, which makes these species useful for investigations of cardiac morphology ...

Plant‐Derived Treatments for Monogenean Parasites in Farmed Fish: A Systematic Review and Meta‐Analysis

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 ...

Productive performance of Arapaima gigas in temperate climate ponds

Revista de Investigaciones Veterinarias del Perú, 2023
The study monitored the productive performance of the paiche (Arapaima gigas) for 30 months under temperate climate conditions on the Central Coast of Peru. After 40 days of acclimatization and with 80% survival, the fish (n: 32, weight: 44 ± 34 g, length: 17.6 ± 4.9 cm) were transferred to a greenhouse pool (8 fish/m3) and fed at 5 % of their body ...

The catch of the day: The shortcomings of promoting sustainable seafood consumption in Peru

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
This study investigates the meaning and application of “catch of the day” in Peru by analyzing 233 news articles and genetically testing 43 fish samples from restaurants. Results show that media frequently use the term as a vague marketing phrase, while genetic testing reveals a 60% mislabeling rate. These findings suggest that “catch of the day” lacks

Endoscopy application in broodstock management of Arapaima gigas (Schinz, 1822) [PDF]

Journal of Applied Ichthyology, 2016
First paragraph: The air-breather fish Arapaima gigas (Schinz, 1822) is an emblematic species of the Amazon with adults reaching up to 2.5 m total length. A. gigas is long-considered a promising new candidate species for aquaculture, with reported growth rates of 10 kg over 1 year, no intramuscular spines, and suitability to different production systems.
