(2015-01-01)
The goal of this paper was to determine the effects of seven diets with differents fatty acids sources in hematology of Nile tilapia before and after cold stimulus. Seven diets, with 3% of fatty acid source, were formulated: ...
Zebrafish as a model organism for nutrition and growth: Towards comparative studies of nutritional genomics applied to aquacultured fishes
(2011)
Zebrafish (Danio rerio) is a common research model in fish studies of toxicology, developmental biology, neurobiology and molecular genetics; it has been proposed as a possible model organism for nutrition and growth studies ...
FAAS determination of metal nutrients in fish feed after ultrasound extraction
(Elsevier B.V., 2009-03-15)
This paper proposes a method to determine calcium, magnesium, manganese and zinc in fish feed samples using ultrasound in the analyte extraction process, and subsequent quantification by flame atomic absorption spectrometry ...
Vitamin C supplementation improves growth performance and caudal fin regeneration in zebrafish (Danio rerio)
(2021-01-01)
This study aimed to evaluate the growth performance and fin regeneration rates of zebrafish fed with diets containing levels of vitamin C (Vit C). A basal practical diet was formulated to test six levels of Vit C supplementation ...
The influence of sardine consumption on the omega-3 fatty acid content of mature human milk
(2006-01-01)
Objectives: The purpose of this study was to investigate what effect the ingestion of sardines, rich in omega-3 series polyunsaturated fatty acids, has on the composition of breastmilk. Methods: This was a prospective study ...
