    Monitoring of cadmium accumulation in cephalopods processed in gujarat coast
    (Asian Fisheries Society, 2009) Murthy, L.N.; Panda, S.K.; Khasim, D.I.; Badonia, R.
    Heavy metal accumulation in cephalopods has been one of the intricate issues in seafood export scenario in India. In recent years, many export consignments of cephalopods processed in Gujarat region were rejected on account of high levels of cadmium. To elucidate this problem, cephalopods landed at different landing centres and processed by various processing units were monitored during the period 2006-07. Among commercial samples of cephalopods, cuttlefish tentacles (0.52±0.08 ppm), squid tentacles (0.28±0.02 ppm) and frozen octopus (0.59±0.1 ppm) recorded highest accumulation of Cadmium. Organ-specific analysis revealed highest accumulation of Cd in the gut of Sepiella inermis (3.34±0.43 ppm) and Squid Uroteuthis (Photololigo) duvauceli (5.31±0.43 ppm). Similarly, in the Purpleback flying squid Sthenoteuthis oualaniensis, which is now a days landed by multiday fishing trawlers, highest residue level of Cd was observed in the liver (568.5 ±15 ppm), followed by gills, eyes and tentacles. Among different species of Octopus, highest accumulation was recorded in Octopus macropus (2.28± 1.11 ppm), followed by O. membranaceus (1.86 ±0.35 ppm) and O. defilippi (1.72 ±0.82 ppm). In order to find out the source of Cd, simulation studies were carried out by soaking squid muscle in ink, signifying the fact that poor post harvest handing and consequent rupture of ink sac, followed by soaking in ink-mixed water could be a reason behind high levels of Cd accumulation in cephalopods landed in Gujarat coast.

    Palm impression technique: a simple tool to popularize good hygiene and sanitation practices among fish handlers
    (Society of Fisheries Technologists (India), 2005) Rao, B.M.; Jeeva, J.C.; Khasim, D.I.
    In order to ensure the safety of the fish consumer, it is utmost importance to popularize good sanitation and hygiene practices among fish handlers, viz., crew of the mechanized trawlers, traditional boat operators, loading and unloading workers at the fishing harbour and fish vendors. Since most of the fish handlers are educationally backward, the conventional bacteriological techniques to demonstrate bacterial load are beyond their level of comprehension. A simple, participatory technique, the Palm Impression Technique (PIT), was found to be an effective tool for popularizing good hygiene and sanitation practices, among these fish handlers. PIT was demonstrated on fishing boat and fish handlers. PIT is recommended for use in extension programmes for on-site demonstrations in fish markets, landing centres, fishing vessels, fishing villages, peeling sheds and processing plants.

    Simple interventions to preserve quality of iced fish and minimize post-harvest losses
    (Society of Fisheries Technologists (India), 2010) Khasim, D.I.; Rao, B.M.; Chattopadhyay, A.K.
    Fish is highly perishable material and it undergoes bacterial, enzymatic and biochemical decomposition after death. The quality of fish or prawn reaching the consumer or the processing factories will greatly depend on how the fish is handled after the catch; how it is preserved and transported before it reaches the user. Since 50-70% of the total landing of fish is consumed as fresh, it is absolutely important that efficient and hygienic practices are employed, so as to ensure that fish reaches the consumer in very fresh condition. In ambient conditions, the fish becomes unfit for human consumption in about 8 to 12 h after they are taken out of water. Hence, it is imperative to cool them down with crushed ice as early as possible after they are caught, in order to retain their freshness for the maximum length of time.
