    Some Fungal Infestations of Dried Fishes in Cochin
    (Society of Fisheries Technologists (India) Cochin, 1985) GUPTA, RANU; SAMUEL, C. T
    Dried fish constitutes a regular item of trade in India, particularly in the interior parts far away from the sea and rivers. The poor section of the society is the main consumer. The quality of dried fish never receives much attention at any stage of processing (drying) and storage. A good amount of these fish is discarded during drying due to fungal growth to avoid the danger of mycotoxin production. A survey of the dried fish from the Cochin markets had revealed that they do carry fungal infestations and their chances of mycotoxin production cannot be ruled out as the strains of Aspergillus fiavus, Aspergillus ochraceus and Fusarium spp. have been isolated.

    PRESERVATION OF SARDINELLA LONGICEPS IN ICED AND CHILLED SEA WATER PART I- CHANGES DURING STORAGE WITH PARTICULAR REFERENCE TO BACTERIAL LOAD AND NITROGENOUS COMPOUND
    (Society of Fisheries Technologists (India) Cochin, 1985) KRISHNAKUMAR, S; HIREMATH, G. G; MENON, N. R; SHETTY, H. P. C
    Oil sardines in prime condition were subjected to onboard chHling; Two lots were chilled in CSW (samples C and Cl), a third lot was chilled in crushed ice (sample I) and a fourth lot left uniced on deck (Sample AI). Upon landing sample AI was iced and sample CI was removed from the CSW and iced. All the four samples were kept in a chilled room for storage studies. The fish chilled and stored in CSW rec?rd~d the least, and the fish subjected to delayed icing, the highest values for all the m~1ces of spoilage namely, free amino nitrogen, trimethylamine (TMA) and total volat1l~ b?-se nitrogen (TVBN). The total psychrophilic bacterial number also showed a s1mtlar trend. The organoleptic assessment of the cooked samples revealed C I,CI, AI to be the order of preference throughout the storage. This assessment was found tc hold good for the rest of the parameters as well. The CSW held fishes were found to be distinctly superior to the iced ones for the first five days of storage. Su?h a ~arked prevalence in quality for five days would suffice for the fish to fetch a premmm m t~e_ market over other landings of the same fish whether chilled or unchilled .. _Chilhngonboard in CSW and icing the same after landings, did not show encouragmg results

    ANTIBIOTIC SENSITIVITY OF VIBRIO PARAHAEMOLYTICUS STRAINS
    (Society of Fisheries Technologists (India) Cochin, 1985) PRADEEP, R; LAKSHMANAPERUMALSAMY, P
    The strains of Vibrio parahaemolyticus isolated from water, sediment, plankton, fish and prawn of Cochin backwater were tested for sensitivity to ten antibiotics namely, ampicillin, chloramphenicol, gentamycin, kanamycin, neomycin, oxytetracycline, penicillin, polymyxin-B, streptomycin and sulphadiazine. Of the 120 isolates tested, 96.7 and 93.3% were sensitive to gentamycin and chloramphenicol respectively. No strain was sensitive to penicillin and only 5% were sensitive to kanamycin. Isolates from fish and prawn showed higher resistance to ampicillin and none of them was sensitive to kanamycin. Multiple resistant V. parahaemolyticus strains were more in prawn than in other sampels.
