New Fish meal plant at Karwar to process oil sardine

Karnataka recorded an appreciable catch of 1,00,179 t of oil sardine in 2007. The boom in oil sardine landings has lead to the establishment of a new fish meal plant at Baithkol landing centre of Karwar which became functional in March, 2008 (Fig. 1). The Karnataka Fisheries Development Board has leased out the fish meal plant to a private company, Sai Annapoorna Bio-Protein Private Ltd. The products manufactured by the fish meal plant are fish oil and fish meal powder. They supply fish oil to CP Aquamarine which exports the fish oil to south-east Asian countries such as Vietnam and Thailand. The fish meal powder is used as prawn feed and it is procured and marketed by CP Aquamarine. The company procures fish from Mangalore to Goa from boat owners and agents. The average supply of fish is 200 t/day. The company processes only oil sardine (Sardinella longiceps) for the manufacture of fish meal and fish oil

Techno-economic performance of mechanised fishing in Karwar, Karnataka

The techno-economic and financial performance of mechanised purse seiners and trawlers operating in Karwar Fishing Harbour was compared using various indicators. The average diesel consumption per trip was 179 l for purse seiners and 79 l for trawlers. The average operating cost and gross revenue per trip were `21,818 and `44,383 respectively for purse seiners and `4,803 and `6,571 respectively for trawlers. Oilsardines and mackerels contributed more than 85% of the catch of purse seiners whereas shrimps and flatfishes contributed nearly 50% of the catch of trawlers. Capital productivity was higher (operating ratio - 0.49) for purse seiners than trawlers (operating ratio - 0.73). The economic and financial performance indicators like net benefit-earnings ratio (0.43), benefit-cost (BC) ratio (1.75) and internal rate of return, IRR (117%) were higher for purse seiners which suggested that the investment on purse seiners is a more viable undertaking when compared to trawlers in the location

Heavy landing of Charybdis smithii and need for proper utilization

Heavy landings of Charybdis smithii during the January to March, 2020 was documented in Mangalore fisheries harbour. These crabs were the part of trawl discards as geo-coded in situ data collection on trawl discards showed that C. smithii was available along Karnataka coast during August to December and in May as pelagic or semi-pelagic shoals from a depth range of more than 100 m. Landing of this species in Fisheries Harbours was generally rare since there was very limited market demand for these crab

Adoption of ingenious fishing method to augment fish catch in coastal karnataka

Gillnets are one of the important gears contributing to the marine fish landings of Karnataka. A variety of gillnets (drift, bottom set, encircling and entangling), are deployed in the fishery. The smaller monofilament gears are operated by small non-motorized and motorized crafts. The larger polyamide high-density polyethylene nets are operated from large mechanized crafts. The use of large meshed knotted monofilament gillnets deployed from mechanized trawlers is a novel introduction and has enabled fishers to operate over submerged banks, rocky patches and reefs

Batoid fishes (Elasmobranchii: Rhinidae, Rhynchobatidae, Rhinobatidae, Glaucostegidae and Dasyatidae) from the southeastern Arabian Sea

Batoid fishes representing families Rhinidae, Rhinobatidae, Glaucostegidae (Order: Rhinopristiformes) and Dasyatidae (Myliobatiformes), with limited information available from southeastern Arabian Sea off Karnataka coast are described. The distribution of five Rhino rays viz., Rhynchobatus australiae, Rhynchobatus laevis, Rhinobatos punctifer, Glaucostegus granulatus, Rhinobatos lionotus and twelve sting rays such as Himantura leoparda, Himantura undulata, Himantura tutul, Maculabatis arabica, Neotrygon indica, Pastinachus ater, Pastinachus gracilicaudus, Pteroplatytrygon violacea, Pateobatis fai, Pateobatis bleekeri, Taeniurops meyeni and Urogymnus asperrimus is reported. Further, based on spotting patterns recorded on dorsal surface and contour of ocellae, five morphotypes of Himantura leoparda, and two of Himantura tutul are illustrated. Observations on six species (Rhinobatos punctifer, Rhinobatos lionotus, Himantura undulata, Himantura tutul, Neotrygon indica and Pastinachus gracilicaudus) is given
