Ontogenetic development of tetra Astyanax lacustris (Characiformes: Characidae)

open access: yesNeotropical Ichthyology, 2018
Ontogenetic development of the tetra Astyanax lacustris was studied under laboratory conditions. Larvae obtained by induced reproduction were maintained individually in tissue-culture plates, at 25°C. Daily observations and morphometric measurements were

Coping styles in farmed fish: consequences for aquaculture [PDF]

open access: yes, 2017
Individual differences in physiological and behavioural responses to stressors are increasingly recognised as adaptive variation and thus raw material for evolution and fish farming improvements including selective breeding. Such individual variation has

Grape (Vitis Vinifera) Pomace Flour as Pigment Agent of Quail Eggs

open access: yesBrazilian Journal of Poultry Science
The aim of the study was to evaluate the effect of dietary grape pomace flour (GPF) inclusion on the performance and egg quality of European quails (Coturnix coturnix coturnix) in lay. One hundred ninety-two (192), 42-day-old quails were distributed in a

Influence of the temperature on the early larval development of the Pacific red snapper, Lutjanus peru (Nichols & Murphy, 1922)

open access: yesLatin American Journal of Aquatic Research, 2015
The Pacific red snapper, Lutjanus peru, is a commercially important species throughout its distribution range, making it a good alternative for aquaculture; however, there is few information regarding environmental conditions and their influence on early

Silky Fowl (Gallus gallus domesticus) Dietary Supplementation with Dried Red Pepper (Capsicum annuum): Effects on Egg Quality, Blood Biochemical Parameters, and Egg Storage Stability

open access: yesPoultry
Egg yolk coloration influences consumer perceptions of table eggs. Red pepper (Capsicum annuum) is a known dietary source of carotenoids, which enhances yolk pigmentation, but its effects in silky fowl (SF) remain unexplored.

The effect of adding green concentrate based on Azolla pinnata and Spirulina platensis on the quality of quail eggs (Coturnix japonica) [PDF]

open access: yesBIO Web of Conferences
The study evaluated the effect of Azolla pinnata and Spirulina platensis-based green concentrates on quail (Coturnix japonica) egg quality. A completely randomized design was employed with three treatments: P0 (control), P1 (10% Azolla), and P2 (10 ...

A Case History of Abnormal Yolk Pigmentation

open access: yesPoultry Science, 1963
Abstract DECREASED yolk pigmentation resulting in so-called “platinum yolks” has been noted in eggs of chickens in several areas of the United States and Canada during the past few years, according to personal communications of the authors with poultry investigators.

Effect of grass–clover forage and whole-wheat feeding on the sensory quality of eggs [PDF]

open access: yes, 2010
BACKGROUND: A sensory panel evaluated the sensory profile of eggs from hens from three experimental systems: (1) an indoor system × normal layer diet (InL), (2) a grass–clover forage system × normal layer diet (GrL), and (3) a grass–clover forage system

Early ontogeny and swimming behavior of larvae of the neotropical fish Prochilodus costatus Valenciennes 1850 and Prochilodus argenteus Spix & Agassiz 1829 (Characiformes: Prochilodontidae) [PDF]

open access: yes, 2016
Early development of fish larvae is a highly dynamic process and its study may provide important information about ontogenetic development, bioenergetic growth, behaviour, taxonomic characteristics for identification in natural environments ...

Evaluation of Carotenoid Pigments for Coloring Egg Yolks

open access: yesPoultry Science, 1960
Abstract MUCH has been written about the role of ingested xanthophylls for pigmenting broilers and also for coloring egg yolks. The great majority of this past research, however, involved the feeding of natural ingredients as yellow corn, corn gluten meal, and alfalfa meal, etc., rich in xanthophylls or crude concentrates made from these natural ...
