lndia has a coastline of 8.129 km with a continental shelf of 4,14,868 sq. km. Its marine resources are spread in the lndian Ocean, Arabian Sea and in the Bay of Bengal. It has an Exclusive EconomicZone of 2.02 million square km comprising 0.86 million sq. km on the West coast, 0.56 million sq. km of the East coast and 0.60 million sq. km around Andaman and Nicobar Islands, with a harvestable fishery fishery potential of 3.9 million tonnes

Assessment of mutagenic, hematological and oxidative stress biomarkers in liver of Nile tilapia,Oreochromis niloticus(Linnaeus, 1758) in response to sublethal verapamil exposure

Drug and Chemical Toxicology (2016)

Malachy N.O. Ajima Pramod Kumar Pandey Kundan Kumar Nalini Poojary

The influx of pharmaceutical drugs and their metabolites have been reported to cause negative impact on aquatic biota. In this study, effects of long-term exposure of verapamil on mutagenic, hematological parameters and activities of the oxidative enzymes of Nile tilapia, Oreochromis niloticus were investigated for 60 days exposure at the concentrations of 0.29, 0.58 and 1.15 mg L−1 in the fish liver. The exposure resulted in significantly high (p < 0.05) micronuclei induction of peripheral blood cells at the peak on day 30 at 1.15 mg L−1. Compared with the control, there was significant increase (p < 0.05) in white blood cell counts and red blood cell distribution width (RDW), with a reduction in hemoglobin (Hb), red blood cell counts (RBCs), mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) level as the concentration of the drug increased. The indices of oxidative stress biomarkers (lipid peroxidation and carbonyl protein) showed elevated level, depicting a positive correlation with both time and concentration. More so, the activity of energy-related parameter (Na+ -K+- ATPase) in the tissue was significantly inhibited (p < 0.05) at the end of 60 days exposure period. Further, the activity of catalase (CAT) was inhibited while reduced glutathione (GSH) level was decreased in the liver tissue. There was increase in the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione–S-transferase (GST) after 30 days at 0.29 mg L−1. The study demonstrated that prolonged exposure to verapamil at sublethal concentration can result in mutagenic effects and oxidative dysfunctions in O. niloticus.

Does Tobacco (Nicotiana tabacum) Leaf Dust Save the Life of Rohu (Labeo rohita) Fingerlings During Transport?

Journal of Aquaculture Research & Development (2017)

R. Dinesh Chandra Prakash Chadha NK Nalini Poojary Sherry Abraham

Fishes undergo a multi-phase of stress due to multiple stressors involved during transportation which is an inexorable and indispensable operation in aquaculture.The aim of this study is to promote a novel, inexpensive, active and eco-friendly sedative to replace expensive and toxic sedatives used in aquaculture.With this intention, we investigated the efficacy of tobacco leaf dust as a sedative for the transport of rohu (Labeo rohita) fingerlings.The experiment of sedative efficacy and simulated transportation was conducted for 12 h in glass tanks (30 L capacity) and plastic bags (75 cm length × 45 cm wide), respectively with different concentrations of tobacco leaf dust such as 0 ppm, 25 ppm, 50 ppm, 75 ppm, 100 ppm and 125 ppm among which 0 ppm was used as control.The fingerlings (6.45 ± 0.68 cm and 3.29 ± 0.52 g) were stocked at a stocking density of 10 fishes/ tank and 30 fishes/ plastic bag in triplicates.The induction and recovery times observed in the anesthetic bath significantly (p<0.05)decreased and increased with increase in the concentrations of tobacco leaf dust.The lowest effective dose found to produce induction (≤ 15 min) and recovery (≤ 5 min) was 25 ppm and the same was effective in inducing light sedation in rohu during the behavioral response observation.Mortality rate (15% to 40%) of fingerlings during transportation was significantly higher in control (without sedative) than the sedative doses of tobacco.Also, poor water quality was noticed in control group with the serious changes in hemogram and leukogram of fingerlings.The experimental results revealed the efficacy of tobacco in minimizing the metabolic activity of the fishes and thereby reducing the water quality deterioration and stress during transportation.Therefore, the present study reveals that tobacco leaf dust (25 ppm) could be a futuristic sedative for safe and successful transportation of L. rohita fingerlings.
