Hemolymph osmolality, ion concentration, acid–base balance, and immune parameters in Macrobrachium rosenbergii (15–20 g) were measured after 8 days of exposure to 0–0.3 mg l 1 trichlorfon. A significant depression in hemolymph osmolality and Cl 1 contents were observed with exposure to 0.3 mg l 1 trichlorfon. Similarly, hemolymph pH, HCO3 , and TCO2 decreased significantly when prawns were expo...

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...

Giant freshwater prawn (Macrobrachium rosenbergii), a commercially important crustacean species, is widely distributed across the Indo-Pacific region. Genetic diversity of this species from five different rivers (Krishna, Mahanadi, Hooghly, Narmada and Kalu) of India was investigated using 5 polymorphic microsatellite loci. The number of alleles across loci varied from 4 to 9. The mean expected...

Sexual dimorphism and differential growth rate is evident in Macrobrachium rosenbergii and one of the major hurdles in the uptake of commercial farming. Two of the main difficulties for communal culture of many crustaceans are cannibalism and the social suppression of the growth. But crustaceans are blessed with ‘Autotomy; regeneration of organs’. There was a statistically significant differenc...

An experiment was conducted at Dumurpota of Satkhira district for six months to compare the production performance prawn (Macrobrachium rosenbergii) under all-male and mixed sex culture systems with carps (Labeo rohita Catla catla). A total experimental ghers were used two treatments in triplicates: (T1) (T2). In both treatments, prawns stocked a rate 10,000 PL/ha while C. catla L. each 650 fin...

Current study explored the acute toxicity and oxidative stress of ammonia-N on Macrobrachium rosenbergii. Prawns were exposed to at 3.01, 3.55, 4.18, 4.92, 5.80, 6.82, 8.04 mg·L−1 for a 96 h test. In subsequent sublethal text, they 0.5 or 1.88 (1/2 LC50) 3, 8, 12, 24, 48, 72 h. The total superoxide dismutase (T-SOD) activity, catalase (CAT) activity malondialdehyde (MDA) content detected in mus...
