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

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]
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.

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