Reproductive Biology of the Freshwater Shrimp Macrobrachium Carcinus (L.) (Decapoda: Palaemonidae) from Costa Rica, Central America [PDF]

open access: yesJournal of Crustacean Biology, 2009
Abstract Macrobrachium carcinus, one of the largest freshwater shrimp of the east coast of the Americas, is commercially fished in certain parts of the region. We present data concerning the reproductive biology of the species, and compare findings with those published for other species of Macrobrachium. Ovigerous females were collected monthly between

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

open access: yesLatin 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

Maturation and growth curves of Macrobrachium Carcinus (Linnaeus) (Crustacea, Decapoda, Palaemonidae) from Ribeira de Iguape River, southern Brazil [PDF]

open access: yesRevista Brasileira de Zoologia, 1994
In this paper, female Macrobrachium carcinus (Linnaeus, 1758) maturation curve, weight/length relationship, length and weight growth curves were studied. Prawns were captured, by traps, in Ribeira de Iguape river (24oS and 47oW), southern Brazil. There were used 207 females. It was observed that M.

Potentialités et intérêts de l'élevage larvaire de la crevette d'eau douce indigène Macrobrachium carcinus (L.) (Palaemonidae) aux Antilles françaises [PDF]

open access: yesBulletin Français de la Pêche et de la Pisciculture, 1999
De précédents travaux, réalisés en laboratoire, ont montré que le développement larvaire de Macrobrachium carcinus nécessitait un environnement salin. Le nombre de larves mises en élevage lors de ces essais était cependant trop faible pour envisager une production de masse de l'espèce.

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

open access: yesAquac 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 ...

Proteomic analysis of digestive tract peptidases and lipases from the invasive gastropod Pomacea canaliculata

open access: yesPest Management Science, Volume 79, Issue 4, Page 1420-1430, April 2023., 2023
We discovered diverse peptidases and lipases in the intestine of the gastropod Pomacea canalicutala, which could be a useful platform to evaluate natural inhibitors to control this invasive species. Abstract Background The invasive gastropod Pomacea canaliculata has received great attention in the last decades as a result of its negative impact on ...

Diseases of the giant river prawn Macrobrachium rosenbergii: A review for a growing industry

open access: yesReviews in Aquaculture, Volume 15, Issue 2, Page 738-758, March 2023., 2023
Abstract The giant river prawn, Macrobrachium rosenbergii, is a major focus of aquaculture in tropical and sub‐tropical regions around the globe. Over the last 30 years, culture of M. rosenbergii has increased exponentially as demand has risen both for domestic consumption and for international export trade.

Welfare of Decapod Crustaceans with Special Emphasis on Stress Physiology

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
Despite the growing concern on animal welfare in crustacean farming, both from legislative bodies as well as the common public, studies on welfare are limited and transfer to routine farming is missing. While biocertification schemes such as the Aquaculture Stewardship Council (ASC) involve a welfare dimension, these dimensions cannot be communicated ...

White spot syndrome virus host range and impact on transmission

open access: yesReviews in Aquaculture, Volume 14, Issue 4, Page 1843-1860, September 2022., 2022
Abstract White spot syndrome virus (WSSV), the etiological agent of white spot disease (WSD), is a significant pathogen affecting shrimp farming industry worldwide. White spot syndrome virus is a generalist virus mainly infecting decapod crustaceans. The aims of this review were to: (1) Re‐evaluate and update the status of reported WSSV host and vector

Local olfactory interneurons provide the basis for neurochemical regionalization of olfactory glomeruli in crustaceans

open access: yesJournal of Comparative Neurology, Volume 530, Issue 9, Page 1399-1422, June 2022., 2022
Central olfactory pathway in the brain of the hermit crabs Pagurus bernhardus and Coenobita clypeatus: summary of glomerular structure and neurochemistry. Abstract The primary olfactory centers of metazoans as diverse as arthropods and mammals consist of an array of fields of dense synaptic neuropil, the olfactory glomeruli.
