Ovarian Staging in Eyestalk Ablated Females of Farfantepenaeus Paulensis: A Histologic, Morphometric, and Biochemical Analysis [PDF]

Journal of Crustacean Biology, 2007
Abstract This study focuses on the ovarian maturation stages in Farfantepenaeus paulensis, which are reported for each stage with histologic, stereological, and morphometric analyses, as well as the specific female protein profile. Unilateral eyestalk-ablated females were dissected and the middle lobes of each ovary were rinsed in cold 100 mM phosphate

Carotenoids Functionality, Sources, and Processing by Supercritical Technology: A Review

Journal of Chemistry, Volume 2016, Issue 1, 2016., 2016
Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development.

Development of a Promising Fish Model (Oryzias melastigma) for Assessing Multiple Responses to Stresses in the Marine Environment

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
With the increasing number of contaminants in the marine environment, various experimental organisms have been “taken into labs” by investigators to find the most suitable environmentally relevant models for toxicity testing. The marine medaka, Oryzias melastigma, has a number of advantages that make it a prime candidate for these tests. Recently, many

Production Response and Digestive Enzymatic Activity of the Pacific White Shrimp Litopenaeus vannamei (Boone, 1931) Intensively Pregrown in Microbial Heterotrophic and Autotrophic‐Based Systems

The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
Shrimp postlarvae were reared into different microcosm systems without water exchange; a traditional system based on simple fertilization to improve microalgae concentration (control), an autotrophic system (AS) based on the promotion of biofloc and biofilm by the addition of fertilizer and artificial substrates and a heterotrophic system (HS) based on

The use of oxygen consumption and ammonium excretion to evaluate the toxicity of cadmium on Farfantepenaeus paulensis with respect to salinity

Chemosphere, 2011
The main purpose of the present study was to detect the acute toxicity of cadmium (Cd) in F. paulensis and to investigate its effect on oxygen consumption and ammonium excretion different salinities. First, we examined the acute toxicity of Cd in F. paulensis at 24, 48, 72, and 96-h lethal concentration (LC50).
