Variations of digestive enzymatic activity of the longarm river prawn, Macrobrachium tenellum (Smith 1871) adapted from the wild to culture with prepared meals

Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 681-692, June 2022., 2022
Abstract Macrobrachium tenellum is an omnivorous freshwater prawn living in rivers near the coast and in coastal lagoons with potential to be cultured. It is distributed in rivers, estuaries, and coastal lagoons, and in each of those habitats, it has access to food items with different features and nutritional content.

Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans

Biological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022
ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.

Form‐Specific and Probabilistic Environmental Risk Assessment of 3 Engineered Nanomaterials (Nano‐Ag, Nano‐TiO2, and Nano‐ZnO) in European Freshwaters

Environmental Toxicology and Chemistry, Volume 40, Issue 9, Page 2629-2639, September 2021., 2021
Abstract The release of engineered nanomaterials (ENMs) to the environment necessitates an assessment of their environmental risks. The currently available environmental risk assessments (ERA) for ENMs are based on an analysis of the total flows of a specific ENM to the environment and on ecotoxicity studies performed with pristine ENMs.

Masters of communication: The brain of the banded cleaner shrimp Stenopus hispidus (Olivier, 1811) with an emphasis on sensory processing areas

Journal of Comparative Neurology, Volume 528, Issue 9, Page 1561-1587, June 15, 2020., 2020
Cleaner shrimps feature a broad communicative repertoire which is considered to depend on superb motor skills and the underlying mechanosensory circuits in combination with sensory organs such as the two pairs of antennules and antennae, which are used both for attracting client fish and for intraspecific communication.

PROTOCOL FOR EXTRACTION OF BACTERIAL METAGENOME DNA TO PRAWN Macrobrachium carcinus L

Tropical and Subtropical Agroecosystems, 2011
<p>In this work we adapted a protocol for the extraction of metagenomic DNA (ADNmg) bacteria in the digestive system (intestines, stomach and hepatopancreas) of <em>Macrobrachium carcinus</em> L., with reference to the method of extracting bacterial DNA from soils and sediments (Rojas-Herrera <em>et al</em>., 2008).

Identification and Characterization of the Lipid Transport System in the Tarantula Grammostola rosea [PDF]

, 2015
Lipids due to its hydrophobic nature are transported in the hemolymph mainly by lipoproteic fractions. In the present work we studied the lipoproteic fractions present in the hemolymph of the spider Grammostola rosea.

FOOD ACCEPTANCE IN DIFFERENT LARVAL STAGES OF <i>Macrobrachium carcinus</i>

Boletim do Instituto de Pesca, 2021
Food acceptance in different larval stages of Macrobrachium carcinus was evaluated by investigating the stage at which the ingestion of inert moist diet food begins and by the incidence of Artemia nauplii and inert moist diet in the digestive tract throughout development. Two experiments were carried out: in the first study, the acceptance of the inert

Digestive enzymes profile of the midgut gland of juvenile painted river prawn (Macrobrachium carcinus)

Aquaculture Reports, 2020
This study assessed the activity of the main digestive enzymes in juveniles of the painted river prawn Macrobrachium carcinus. Prawns reared in 24 m2 tanks at a density of 10 individuals. m−2 for 45 days were fed a commercial diet with 40 % crude protein.
