- ItemActivity of Soil Fungi of Mangalvan, The Mangrove Ecosystem of Cochin Backwater(Society of Fisheries Technologists (India) Cochin, 1990) PRABHAKARAN, N; GUPTA, RANUResults of the qualitative screening of fungal isolates for the production of hydrolytic enzymes and phosphate solubilization are given in Table 1. Table 2 presents the percentage of the positive isolates for each enzyme production. It is found that most of the fungal isolates were capable of producing one or the other hydrolytic
- ItemBacteriology of Indian Oil Sardine (Sardinella longiceps Valenciennes) Stored in Chilled Sea Water(Society of Fisheries Technologists (India) Cochin, 1990) SHETTY, T. S; SHETTY, T M RThe changes in the bacteriology of Indian oil sardine (Sardinella longiceps valenciennes) and the medium surrounding the fish during storage in chilled sea water (2 i 1°C) were detennined by the identification of bacterial isolates upto their generic level. The flora of the freshly caught fish consisted mainly Micrococcus spp., Bacillus spp., Flavobacterium spp., Pseudomonas spp., Acinetobacter spp. and Vibrio spp., While that of the freshb' collected sea water consisted mainly Micrococcus spp., Vibrio spp., Pseudomonas spp., Arthrobacter spp., Bacillus spp. and Aeromonas spp. The flora of the fish and the medium surrounding the fish after 10 days storage consisted mainly of Pseudomonas spp., Vibrio spp., Flavobacterium spp., Acinetobacter spp. and Aeromonas spp
- ItemComparative Toxicity of Four Detergents on a Prawn Metapenaeus dobsoni (Miers)(Society of Fisheries Technologists (India) Cochin, 1990) SAKUNTHALA, B; SHANMUKHAPPA, H; NEELAKANTAN, BThe toxicity bioassay experiment was conducted using four detergents, namely, linear alkylbenzene sulfonate (LAS), branched alkylbenzene sulfonate (BAS), alfa olefin sulfonate (AOS) and sodium sulfonate (SS.) 0.1 Metapenaeus dobsoni juveniles. The results indicated that, LAS was most toxic and AOS the least and were in the order: LAS>SS. >BAS>AOS. The LCN, LC50 and LC84 concentrations for all the detergents were calculated for 24, 48, 72 and 96 hours. The 95 % confidence limits for LC50 and slopes were also calculated by probit analysis.
- ItemCopper, Chromium and Manganese in Some Fishes of Kali Estuary, Karwar(Society of Fisheries Technologists (India) Cochin, 1990) VEER, M. P; BHAT, U. G; SHANMUKHAPPA, HCopper, 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.
- ItemEstimation 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, LEELAVariation 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).
- ItemFilth and Decomposition in Prawns from Peeling Sheds Around Cochin(Society of Fisheries Technologists (India) Cochin, 1990) THOMAS, FRANCIS; MATHEW, KURUVILASamples 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.
- ItemPlankton 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, BThe 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.
- ItemUtilization 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. CA 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.
