Survival ofMacrobrachium amazonicumembryos submitted to cooling

Zygote, 2017
SummaryCooling techniques have several applications for reproduction in aquaculture. However, few studies have sought to create protocols for cooling and cryopreservation ofMacrobrachium amazonicumembryos. Thus, the objective of this work was to verify the survival ofM.

Energy allocation trade-off in Macrobrachium amazonicum, with no resting stage

Zoologischer Anzeiger, 2021
Abstract In this study, we investigated which strategy Macrobrachium amazonicum populations use to survive in river and estuary environments. In each environment, abiotic factors were analyzed in situ, and ovigerous females and males of M. amazonicum specimens were captured.

Toxicity of cryoprotectants agents in freshwater prawn embryos of Macrobrachium amazonicum

Zygote, 2014
SummaryThe process of cooling and cryopreservation of prawn embryos is a viable alternative for a continuous supply of larvae for freshwater prawn farming ponds. However, studies involving the application of those techniques as well as on toxicity of cryoprotectants in freshwater prawn embryos are scarce.

Macrobrachium amazonicum (Crustacea, Decapoda) Used to Biomonitor Mercury Contamination in Rivers

Archives of Environmental Contamination and Toxicology, 2019
Open-air landfill's may be are considered as a potential source of human environmental exposure to chemical substances such as, polycyclic aromatic hydrocarbons and toxic metals. Due to possible availability of mercury in the environment caused by open landfill emissions, this study evaluates the spatiality and seasonality of macroinvertebrates, in ...

Histological alterations in gills of Macrobrachium amazonicum juveniles exposed to ammonia and nitrite

Aquatic Toxicology, 2017
Aquaculture has shown great growth in the last decades. Due to the restrictions on water use, production systems are becoming increasingly more intensive, raising concerns about the production water quality. Macrobrachium amazonicum is among the freshwater prawn species with favorable characteristics for production and possibility of intensification ...

Effect of nitrate on the performance and welfare of Macrobrachium amazonicum (Heller, 1862) juveniles

Aquaculture, 2022
Abstract The objective of this study was to evaluate the chronic effect of different nitrate concentrations on the zootechnical performance and welfare of Macrobrachium amazonicum juvenile. A randomized bioassay was conducted over 28 days, with four treatments (0, 8, 16, and 32 mgL−1 N-NO3−) and four replicates.

Feeding habit of the Amazon river prawn Macrobrachium amazonicum larvae

Aquaculture, 2007
Abstract To investigate the feeding habit of Macrobrachium amazonicum , three experiments were carried out assessing the stage at which larvae start exogenous feeding, the acceptance of inert food by different larval stages and the ratio between live and inert diet ingested by larvae at each larval stage.

INFLUENCE OF FASTING TIME ON SHRIMP TRANSPORT OF Macrobrachium amazonicum

2020
El objetivo de este estudio fue verificar la influencia del tiempo de ayuno de la comida de camarones Macrobrachium amazonicum en una simulación del transporte durante el período de 10 horas. Se utilizaron 600 camarones (0,22 ± 0,08 g) en una densidad de almacenamiento de 50 camarones L-1 y dos tratamientos: ayuno previo de 12 h (T12) y 24 h (T24), con
