The catostylid jellyfish Crambionella orsini is the only species that contributes to a fishery in this region. In the October to January months, a seasonal fishery exists along the Kanyakumari, Thiruvananthapuram and Neendakara coast, with catches being made variously by gillnetters, single day trawlers, multi-day trawlers and shore seines. An unprecedented 44 day fishery on the Neendakara coast from December 2020 to January 2021 was investigated in depth, with estimated landings of 453.16 metric tonnes landed at Sakthikulangara and Neendakara Fisheries Harbours in Kollam District, Kerala. Economic efficiency of the fishery from Sakthikulangara Fisheries Harbour was estimated as 44.76 gross value added as percentage of gross revenue and net operating income of `1313 per fishing trip with average earning to a crew member being `510 per trip. The oral arms of C. orsini is the only part of the jellyfish that are traded and exported, mainly to China and South east Asian countries after salt curing. Emergence of this augmentative fishery has come as a boon to fishers combating the regressive environment of the Covid-19 period. Promotion of this fishery with increased processing and export facilities and investigations into value added products from the resource is recommended.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

We report here the capture of dissolved CO2 by the ocean-turf grass, Halophila beccarii and its storage as carbon stock in the sediments extending an area of two hectares in the mudflats of Kadalundi Estuary. The organic carbon content in the seagrass sediment showed gradual increase from 0.473% during January to 0.824% during March. Organic carbon content in the sediment within the Halophila bed was 110134% higher than that of outside the seagrass bed. The three months observation, though a short term study revealed that the mean values of blue carbon stock of Halophila beds of Kadalundi Estaury were at 2.655±0.34 Mg C/ha. The capture potential of dissolved CO2 by the seagrass, unravelled through an experiment involving intact plants showed that the Halophila plants could utilize 21.4%– 25.7% of dissolved CO2 in light within 2 hours.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

Even though industrialization and urbanization are considered as the steppingstone to a country’s development, the effluents released into the water bodies may lead to unrepairable damage to the aquatic environment thereby affecting livelihood of coastal people. The present investigation was done in Cochin inshore waters (9° 59’ 12. 56” N and 76° 16’ 20. 74” E) polluted due to effluent discharge into the canal water connecting to the sea through the lake. The chemical parameters showed wide variation in ammonia content in effluent water which was found to be very high with a value of 4.05 mg/l compared to the normal estuarine water (0.14 mg/l) and was 96% higher in effluent water. Similarly, the phosphate and silicate content of the effluent water was about 84.3 and 87.6% higher than the normal estuarine water. The presence of heavy metals like zinc as well as copper was also observed in the effluent. Experiment conducted in the laboratory using aquatic plants like Eichhornia crassipes, Pistia stratiotes and mangrove such as Rhizophoramucronata and Bruguiera gymnorrhiza for 5 days showed increase in DO and BOD level with decreasing TSS and nutrients. The absorption of ammonium ion was quite low, ranging from 4.0 -10.5%, but toxicity of ammonia was observed to affect the aquatic plant and mangrove used for treatment. The biosorption study was carried out for the removal of heavy metals from the effluent by passing through a column packed with seaweed powder of Sargassum wightti and Kappaphycus alvarezii. Sargassum could accumulate zinc 17.6 (mg/kg) and copper (1.96 mg/kg) whereas Kappaphycus could accumulate 76.1 (mg/kg) of zinc and 16.64 (mg/kg) of copper in different effluent collected from outfall area leaving the elute below the detection level. The main aim of this study is to bring forth a new concept of eco-friendly processes to counter contamination of water bodies by phytoremediation using various aquatic plants and suggest the industries to implement this cost effective technology of effluent treatment. This will ensure reuse of freshwater and protect the fragile aquatic system from pollution besides mining the heavy metals from the seaweed through phytomining.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

The species studied were Parambassis dayi (Bleeker, 1874), P. thomassi (Day, 1870), Ambassis ambassis (Lacepe’de, 1802) and A. gymnocephalus (Lacepe’de, 1802). The fish specimens were collected from the catches of gill nets and seine nets operated in the lake during the period 2015-2016. The b values in the LWRs varied from 2.75 to 3.27. No previous information is available on LWRs for these fish species from Vembanad Lake.
