    Utilization of Low Value Fish - 1. Preparation of Fish Fingers from Croaker and Perches
    (Society of Fisheries Technologists (India) Cochin, 1990) REDDY, LAKSHMINATHA; SHETTY, T. M. R; DORA, K. C
    A method for the preparation of fish fingers from croaker and pink perch meat has been developed. The recipe, ingredients for the paste, batter and the breading mix have been standardised through taste panel studies. An extrusion technique has been used to make fish fingers to the required size and shape rather than sawing of the frozen meatblocks generally followed.

    Plankton of Karwar Waters with Remarks on the Hydrographic Conditions and Fishery
    (Society of Fisheries Technologists (India) Cochin, 1990) NAIK, U. G; REDDY, C. R; SHETTY, D. C; NEELAKANTAN, B
    The results obtained from the investigations on the abundance and seasonal Huctuations of plar k‘on and hydrographic condiiions of fishing areas cf Karwar waters are pres :nted and discussed. The displacement volume of plankton (9.2~29.6 ml/m’) showed two peaks one in November-December and other in February-March. Among the phytoplankton, the diatoms constitute the major part of the total phytoplankton with dominant species like Fragillaria, Coscinodiscus, Thalassiothrix, Chaetoceros, Nirzschina, Rhizosolenia and Biddulphia whereas among the zoopl;nktons, the dominant groups mainly comprised of` copepods, decapod larvae, chaetognaths and medusae. The observed valuis ofhydrographic parameter showed a birnodil peak. A correlation between plankton abundance and fishery has been attempted in this paper.

    Filth and Decomposition in Prawns from Peeling Sheds Around Cochin
    (Society of Fisheries Technologists (India) Cochin, 1990) THOMAS, FRANCIS; MATHEW, KURUVILA
    Samples of prawn meat collected from peeling sheds around Cochin were examined for filth and decomposition. These samples were found to be contaminated by house flies/house fly fragments in 7% samples, flies of the genus Drosophila in 12% samples, red ants/red ant fragments in 19% samples and head louse in 1% samples. 5-6% of the samples were found to be decomposed. It was observed that the smaller the size of the prawn, the higher the contamination by flies and ants and also decomposition.

    Estimation of D10 Value for Salmonella Serotypes Isolated from Processed Frozen Frog Legs
    (Society of Fisheries Technologists (India) Cochin, 1990) RAJAGOPALAN, D; DESHPANDE, C.K; JOSHI, LEELA
    Variation of sensitivity among different serotypes of salmonella was carried out for comparative purpose in the present study. D value of salmonella in Hartsell’s broth was reported to be between 0.025 and 0.55 M rad. S.pvIlorum, S.enteritidis and S_paratypht A showed 0.025 Miad while Scholeaesuns and S.paratyphi B.0.055 M rad (Dorethy et al., 1970).

    Copper, Chromium and Manganese in Some Fishes of Kali Estuary, Karwar
    (Society of Fisheries Technologists (India) Cochin, 1990) VEER, M. P; BHAT, U. G; SHANMUKHAPPA, H
    Copper, chromium and manganese concentrations in the gill, muscle body and whole samples of four estuarine fishes, namely, Mugil cephalus, Sillago sihama, Leiogna- thus brevirostris and Gerromorpha sety"er were determined during the period July- November, 1989. Concentrations of these metals in different body parts varied from species to species. The three trace metals in M. cephalus, S. sihama and L. brevirostris in whole body were in the order Mn > Cr >Cu whereas in G.setQ‘er the abundance was in the order Cr >Cu >Mn. Significant correlation was observed between concentration of metals in gills and whole body in all species except M. cephalus. Considering the trace metals concentration in relation to wet weight, all the metals are within safety limits in edible part.
