    Adoption of quality management practices in seafood processing sector in cochin region
    (Society of Fisheries Technologists (India), Cochin, 2012) Balasubramaniam, S.; Jeeva, J.C.; Ashaletha, S.
    The study was conducted in 34 fish processing units in Ernakulam and Alleppey districts of Kerala, India. Data were collected on the general profile of the seafood processing units, availability of infrastructural facilities and managerial role performance of fish processors. The results revealed that 76.47% of the units were EU approved and 23.53% were Non-EU units. The average quantity handled per day was 11.12 t while the production capacity was 21.51 t day super(-1). For the availability of infrastructural facilities in the processing units, the adequacy index was more than 90. The overall role performance index of the fish processors was found to be 74.46. The adoption of quality management practices was determined in terms of good hygienic practices (Mean: 99.51%), good manufacturing practices (Mean: 97.65%), standard sanitation operation procedures (Mean: 99.08%) and good laboratory practices (Mean: 96.33%). The significant 'F' value in the multiple regression analysis revealed the overall significance of influence of 14 independent variables when taken together in explaining the extent of adoption of good hygienic practices by the fish processing units. Of the fourteen variables, only type of approval and adequacy of infrastructural availability in the processing units positively contributed towards the extent of adoption of quality management practices. The R super(2) value indicated that the 14 variables selected together explained 67.70% of variation in the adoption level. The major constraints expressed by the processors were also listed out.

    Analysis of socio-economic variables and impact of tsunami among the mechanized boat operators in tamilnadu
    (Society of Fisheries Technologists (India), Cochin, 2012) Jeeva, J.C.; Balasubramaniam, S.; Ashaletha, S.; Jeyanthi, P.
    The post-Tsunami fisheries scenario and socioeconomic conditions among the mechanized boat operators in Tamilnadu, India were studied. The data were collected from a randomly selected sample of 60 mechanized boat operators from Cuddalore and Nagapattinam districts (30 per district) in Tamilnadu, India. The average fishing days in a year was 217 and 213 for Cuddalore and Nagapattinam respectively. The average investment on fishing unit was Rs 15.50 and Rs 16.38 lakhs respectively in both the centres. Almost all the respondents in both the districts reported no change in various parameters viz., demand for fish, price of fish, change in the taste or quality of fish, urbanization/migration and changes in health, sanitation, nutritional status and outbreak of any disease after Tsunami. Increased fishing pressure, introduction of steel trawlers, ring seine operation, large mesh trawls, double-rig trawling, single-day to multi-day fishing, larger boats and usage of electronic instruments were found to be the major changes in the post-Tsunami period. Significant changes could be observed in the present value of craft and gear, investment and indebtedness in the pre and post-Tsunami periods. Majority of the respondents in both the study areas expressed satisfaction with the adequacy of mitigation measures such as supply/replacement/repair of fishing devices, technological assistance, credit facilities, health and hygiene.

    Assessment of certain Anthropogenic Interventions and their Impacts along the Indian Coastline
    (Society of Fisheries Technologists (India)Cochin, 2012) Kaladharan, P.; Vijayakumaran, K.; Singh, V. V.; . Asha, P. S; Sulochanan, Bindu; Asokan, P. K.; Valsala, K. K.; Veena, S.; Jayasankaran, L.; Bhint, H. M.
    Coastal anthropogenic activities such as sand mining, disposal of untreated or partially treated sewage and industrial effluents from selected centres along Indian coastline and their possible impacts impairing the coastal environment are discussed with the data collected for two year period from eight maritime states of India. Destruction of macro benthos due to large scale sand mining along the Malabar coast was estimated to show an average of 2760 m-2 day-1 equivalent to 10.42 g m-2 day-1 (wet weight) registering maximum during the post monsoon season. Non biodegradable objects such as polythene carry bags, ropes and sachets were recovered in considerable quantities from the beaches (0.145-9.8 g m-2) as well as from the fishing grounds (32-85 g haul-1). The domestic sewage disposed to Visakhapatnam inshore area registered appreciable density of toxic algal species such as Gonyalux fragilis, Peridnium depressum and Porocentrum gracile. Annual average of mercury in soft tissues of crab Portunus sanguinolentus was found in very high levels from Veraval (2.90 ppm) followed by Tuticorin (2.39 ppm), Visakhapatnam (1.83 ppm) and Cochin (1.77 ppm). However, arsenic levels were very high in all the tissue samples collected from Tuticorin, Mandapam, Chennai and Visakhapatnam

    Biochemical and microbiological evaluation of tuna Loin processing waste
    (Society of Fisheries Technologists (India), Cochin, 2012) Murthy, L.N.; Rao, B.M.; Prasad, M.M.
    The study conducted on the yellow fin tuna loin processing showed a sizeable portion as waste in the form of belly flap, off cut meat, off cut mince from the bone, meat mince, blood meat, head, gut, tail, skin and bone. Analysis of proximate composition of processing waste showed protein content ranging between 18.72 and 23.95%. The fat content was highest in belly flap (7.52%) and lowest in head meat (0.23%). The appreciable amounts of protein (18.73 to 23.95%) and low fat content (0.23 to 1.92%) of off-cut mince, bone meat, head meat and blood meat make them suitable for value addition if other quality parameters are within the acceptable level. Microbiological quality of the tuna processing waste was found acceptable whereas histamine content was on the higher side. Implementation of Good Management Practices (GMP) and Hazard Analysis Critical Control Point (HACCP) system right from capture to processing would facilitate effective utilization of tuna processing waste for value addition.

    Biotyping and antibiotic resistance profile of yersinia enterocolitica associated with seafoods from south-west coast of India
    (Society of Fisheries Technologists(India),Cochin, 2012) Kishore, P.; Lalitha, K.V.; Joseph, T.C.; Thampuran, N.
    This study reports occurrence of Yersinia enterocolitica biotype 1A strains resistant to ampicillin, cephalothin and sulphamethizole in fish and shellfish species landed in southwest coast of India. Thirty finfish and shellfish samples collected from various sources such as farms, retail outlets and landing centres in south-west coast of India were examined for the presence of Y. enterocolitica. Sixty three Yersinia strains were isolated and characterized. Y. intermedia was the most commonly isolated species. Y. enterocolitica biotype 1A was recovered from squid, but did not belong to the pathogenic serogroups O:3, O:5, O:8 or O:9. The antibiotic susceptibility tests of the isolated Y. enterocolitica strains revealed that these strains were resistant (100%) to ampicillin, cephalothin and sulphamethizole. As determined through PCR analysis the Y. enterocolitica isolates from squid carried inv genes, but were negative for ail and yst genes.

    (Society of Fisheries Technologists (India)Cochin, 2013) Kazi, T. G.; Mohite, A. S.; Jadhav, R. R.
    Gillnet is commonly used by the fishermen of Ratnagiri for the capture of seer fish. The present study deals with design, technical specifications and operation of seer fish gillnets (towerchi rapan) operated off Ratnagiri, Maharashtra. The nets were made of webbings of polyamide multifilament of 210d×2×3 to 210d×12×3 having mesh sizes ranging from 70 to 150 mm. Each fleet of net comprised of webbings of different mesh sizes in combination to capture different size groups of fishes, which is not a good practice. The nets were without foot ropes and were operated as surface drift during September to December and column drift during October to May. The seer fish gillnet fishing sector of Ratnagiri comes under the category of ‘small scale drift net fisheries’ as fleet length of majority of the units was below 2500 m.

    (Society of Fisheries Technologists (India) Cochin, 2012) Pandit, D. N.; Ghosh, T. K.
    The study reports the optimized conditions for the live transportation of two air breathing fishes viz., Anabas testudineus and Channa punctatus. The requirement of bimodal oxygen, water and commercial oxygen for packing the fishes was determined. The use and suitable dose of MS-222, a standard fish anaesthetic containing ethyl-m-aminobenzoate as an active ingredient during live transportation was also studied. Five specimens of A. testudineus (total weight 72.50 g) required 385.880 and 497.977 mg oxygen from water and air respectively for packing and transportation for 72 h. For five specimens of C. punctatus (total weight: 57.50 g), 377.182 mg aquatic oxygen and 253.669 mg aerial oxygen was required. The optimum dose of MS-222 for A. testudineus (body weight: 14.00 ± 0.5 g) and for C. punctatus (body weight: 11.55 ± 0.65 g) was determined to be 70.0 mg l–1 and 32.50 mg l–1 respectively. The fishes transported in the optimized conditions reached the destination after 72 h without mortality

    Trawl codend selectivity in respect of silver pomfret pampus argenteus (Euphrasen, 1788)
    (Society of Fisheries Technologists (India), Cochin, 2012) Boopendranath, M.R.; Pravin, P.; Remesan, M.P.; Thomas, S.N.; Edwin, L.
    The silver pomfret Pampus argenteus (Euphrasen, 1788) belonging to the family Stromateidae is an important resource exploited by trawlers in India and is one of the most sought after marine food fish worldwide. Information on trawl selectivity is required in biological investigations, fish stock assessment, fisheries management and fishing gear design and development. The size selectivity for this species in 100 mm diamond mesh codend was estimated using covered codend method and the selectivity parameters were estimated using the software CC 2000 (ConStat, Denmark). The L50, selection range and selection factor were determined as 144.8 mm, 27.3 mm and 1.45 respectively. The optimum mesh size estimated based on the highest reported value of length at first maturity for silver pomfret in Indian waters and the selection factor determined through trawl selectivity experiments was 150 mm, for conventional diamond mesh codends.
