Predation on pirarucu larvae by opportunistic fish species
Acta Amazonica, 2022 One of the constraints in pirarucu, Arapaima gigas farming is the reproduction in captivity, due to inconsistent number of spawning events per reproductive cycle, thus, unreliable availability of juvenile fish. This is a first-hand report on predation of

Enhanced flow sensing with interfacial microstructures
Biosurface and Biotribology, Volume 6, Issue 1, Page 12-19, March 2020., 2020 Biological flow receptors show astonishing performance and are used as models for the design of novel flow sensors. However, the functional importance of interfacial microstructures is seldom discussed in previous review papers. Herein, this review summarises the underlying biomechanical principles in the biological flow receptors and describes the ...

Effect of photoperiod stress assessment and locomotor activity of female lambari (Astyanax bimaculatu) [PDF]
Ciência e Agrotecnologia, 2014 Some studies and scientific investments have been done in aquaculture aiming to minimize the stress of the fish due to different factors, as management, nutritional status, water quality, temperature, photoperiod, and salinity. This study aimed to verify the effect of photoperiod on locomotor activity and plasma levels of cortisol and glucose in female

Insect meals in fish nutrition
Reviews in Aquaculture, Volume 11, Issue 4, Page 1080-1103, November 2019., 2019 Abstract Different studies have shown that insect meals can partially or completely replace the fish and soya bean meals that are commonly used in aquaculture. However, information is lacking on the amino acid and fatty acid contents and digestibility of different insect meals. Moreover, we evaluated different proportions of insect diets and determined

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil
Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017 The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at

The Scientific World Journal, Volume 2016, Issue 1, 2016., 2016 Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in ...

Environmental DNA, Volume 6, Issue 6, November–December 2024.We introduce the metabarcoding gap visualization and demonstrated how it can make comparisons of PCR primers rapidly comprehensible for researchers in the molecular ecology community. We use gap visualization to simultaneously interrogate multiple primer pairs and enhance reference data quality. This has significant impact for study design as selecting

Wild Animals Used as Food Medicine in Brazil
Evidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013 The connection between eating and healing is common in traditional folk medical systems, and the multiple possibilities resulting from the combination of biodiversity and culture confer a wealth and complexity in terms of knowledge of the flora and fauna as to their potential as food medicine.
