The giant river prawn, Macrobrachium rosenbergii (de Man, 1879), is a species of great commercial importance. It farmed under different conditions that translate to range light environments, which impact their behavior and productivity. We present the first study employing both visual modeling beha vioral data evaluate ontogenetic changes in color preferences juveniles adults M. rosenbergii. of...

The State of West Bengal supports a wide variety wetlands covering freshwater, brackish water, and coastal wetlands, both natural manmade wetlands. Directorate Fisheries, Government estimated at 3,111,92.52 ha which include river, canal, beel/ baor, reservoir. A list total 61 cultivated culturable species occurring in freshwater water is provided. Another 21 crustacean fishery added this commun...

This study evaluated feeding patterns and ontogenetic variations in a non-native fish species (Plagioscion squamosissimus) in an isolated lake in the Upper Paraná River floodplain. Quarterly samplings were performed from April 2005 to February 2006 using plankton nets to capture larvae, seining nets for juveniles, and gill nets and trammel for adults. Stomach contents (n = 378) were examined ac...

The effect of acute and chronic cold exposure on heart rate (HR) and neuronal function in crayfish Procambarus clarkii and prawns Macrobrachium rosenbergii was addressed. This is particularly important since prawn farms of this species are used for aquaculture in varied climates world wide. The success of P. clarkii as an invasive species throughout the world may in part be due to their ability...

This paper describes seasonal changes of microcystin-LR (MC-LR) and its glutathione (MC-LR-GSH) and cysteine conjugates (MC-LR-Cys) in three aquatic animals--snail (Bellamya aeruginosa), shrimp (Macrobrachium nipponensis) and silver carp (Hypophthalmichthys molitrix) collected from Lake Taihu, China. MC-LR, MC-LR-GSH, and MC-LR-Cys were determined by liquid chromatography electrospray ionizatio...

Although fish, crustacean, and shellfish are significant sources of protein, they are currently affected by rapid industrialization, resulting in increased concentrations of heavy metals. Accumulation of heavy metals (V, Cr, Mn, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sb, Ba, and Pb) and associated human health risk were investigated in three fish species, namely Ailia coila, Gagata youssoufi, and Mast...
