Abstract: The present study deals with the comparison of immunological and biochemical parameters in the haemolymph of Indian white shrimp
Fenneropenaeus indicus collected from mud bank forming area of (chavakkad) and natural habitat (Kozhikkode). Higher Total hemocyte count (THC) of 63.7 X10
6 cells /mm
3 was obtained with Chavakkad sample in contrast to Kozhikode 61.9 X10
5cells millions/mm
3. Higher phenoloxidase
(PO) activity was found in Chavakkad samples (0.029 units/min) but less in kozhikkode sample (0.011units/min). The PO activity of
F. indicus showed highest titre value (0.180) in plasma, with increased concentration of laminarin. Haemagglutination activity against bacterial cells was found to be strong in the plasma of Chavakkad samples (0.0625) in comparison with Chavakkad samples (0.0123).
F. indicus plasma of Chavakkad samples showed the strongest agglutination titre against human erythrocytes A, B, O and AB (48, 32, 25, 28) than supernatant and pellet. Antimicrobial production assay of Chavakkad sample showed maximum zone of clearance of 10mm with
Bacillus and 12 mm with
Pseudomonas whereas Kozhikode samples showed only 5 mm clearance with
Bacillus and 1mm clearance with
Psedomonas. The protein concentration of Chavakkad and Kozhikode samples were 1129.75µg/ml and 471.5µg/ml respectively. Samples collected from Chavakkad showed maximum glucose concentration of 2757.5µg/ml and less glucose in Kozhikode sample (680 µg/ml). Results evidently reveal that the samples of shrimp haemolymph from non-stressful habitats viz. mud bank formation areas show enhancement in immunological response and biochemical parameters both quantitatively and qualitatively. Studies on the haemolymph provide clear indications about the physiological state and general health of the shrimp which is the most important factor in any aquaculture practice.
