Partial characterization of digestive proteases in adults of bigclaw river shrimp Macrobrachium carcinus

Latin American Journal of Aquatic Research, 2018
The present research was focused to characterize the digestive proteases in Macrobrachium carcinus adults using biochemical and electrophoretic techniques. Our results showed that the alkaline proteolytic activity from males and females did not show significant differences ( P > 0.05) between them, the optimum pH for digestive proteases is 8, and is

Comparative Neuroanatomy of Hydrothermal Vent Shrimps: Ecological Differentiation Among Four Alvinocaridid Species. [PDF]

J Comp Neurol
Hydrothermal vent shrimps share a conserved brain architecture with enlarged mushroom bodies and terminal medullae, shaped by similar environmental pressures. Despite this similarity, some anatomical features near the brain vary between species, suggesting that some ecological factors, such as microhabitat and trophic strategies, also influence nervous

Effect of stocking densities on zootechnical performance and water quality in the rearing of postlarvae of the river prawn Macrobrachium carcinus (Linnaeus, 1758) in oligohaline waters

Brazilian Journal of Animal and Environmental Research
This study evaluated the zootechnical performance of M. carcinus post-larvae reared at different stocking densities in an aquaculture recirculation system in oligohaline waters, as well as monitoring the physico-chemical variables of the water. Twelve circular polyethylene tanks (1000 L) were used, including three treatments (10, 20 and 40 prawn m-2 ...

Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives. [PDF]

Aquac Nutr
Reproductive maturation remains a central bottleneck in crustacean aquaculture, as ovarian development dictates broodstock quality, fecundity, and larval viability. This review synthesizes current knowledge on the physiological regulation of ovarian maturation in decapod crustaceans, emphasizing the interplay of hormones, nutrients, and environmental ...

Lethal salinity and survival for Macrobrachium carcinus larvae subjected to osmotic stress

Estuarine, Coastal and Shelf Science, 2021
Abstract The present study aimed to establish an adequate salinity range for the larviculture of the Macrobrachium carcinus by determining the lethal salinity (LS50) and survival of the larvae subjected to osmotic stress tests. Newly hatched larvae were acclimated at the salinities of 16 and 20 and reared for 20–22 days until reaching Zoea stage VI ...
