Fish gut content from biological collections as a tool for long-term environmental impact studies
(2018-06-01)
Most of the world’s fish fauna is suffering from different types of human impacts and new conservation tools are required. The fish diet analysis is a tool that has been used to evaluate degradation processes of aquatic ...
Reproductive strategies and chromosomal aberrations affect survival in the Rivuliid fish Hypsolebias sertanejo
(Cambridge Univ Press, 2021-02-01)
Rivulidae comprises a family of fish largely distributed in Brazil that includes 201 species, of which 125 are considered endangered. This fact emphasizes the need for development of conservation strategies including studies ...
Phenolic compounds from wines as natural preservative of fish meat
(Faculty Food Technology Biotechnology, 2013-06)
The aims of this work were to investigate the antibacterial effect of phenolic compound combinations and total polyphenols of Argentinean red wines varieties against Escherichia coli ATCC 35218 and Listeria monocytogenes ...
Exceptionally preserved ‘skin’ in an Early Cretaceous fish from Colombia
Studies of soft tissue, cells and original biomolecular constituents preserved in fossil vertebrates have increased greatly in recent years. Here we report preservation of ‘skin’ with chemical and molecular characterization ...
Efeito do álcool e formol sobre a composição isotópica de δ 13C e de δ 15N em Plagioscion squamosissimus e Hypophthalmus edentatus (Pisces, Osteichthyes)
(2011-09-14)
The present study investigates the δ 13C and δ 15N isotopic composition in frozen samples (control), samples in alcohol and in formaldehyde of Plagioscion squamosissimus and Hypophthalmus edentatus. From each individual ...
Deodorization of fish oil by high vacuum distillation: preservation of the chemical characteristics of the oil
(CSIC Consejo Superior de Investigaciones Cientificas, 1993)
The construction and the operation conditions of a high vacuum glass-equipment for deodorizing sardine oil at laboratory scale is described. The equipment working at 120-degrees-C and at a pressure of 0.05-0.1 mmHg maintains ...
