  • A method of immersion of panels for ecological studies on marine fouling and boring organisms

    Srinivasan, V.V.; Mohan, K.C. (1973)
    Fishery Technology
    The importance of studies on the biology of marine foulers and borers needs no emphasis since they cause damage to submerged wooden structures resulting in considerable economic loss. In order to study their occurrence, settlement and to assess the rate of destruction to timber, several immersion techniques using iron racks, cages and rafts have been adopted. On the east and west coasts of India, at the Marine Centres of Forest Research Institute (Waltair, Madras, Cohin and Bombay) investigations have so far been carried out employing the first two methods.

  • Quality of cured fish on the west coast: comparative study with the IS specifications

    Muraleedharan, V.; Unnithan, G.R.; Joseph, K.G.; Unnikrishnan Nair, T.S. (1989)
    Fishery Technology
    Moisture and salt content in cured fish products from various centres on the west coast of India are compared. The moisture contents varied in samples from different centres, whereas the salt content remained more or less uniform. The deviations from the Indian standard specification were highly significant in both cases. The high mean moisture values and low salt values with respect to accepted standards are indicative of the improper drying and poor salting.

  • A scale to measure the attitude towards improved fish processing methods

    Thiagarajan, R.; Mohan, B.; Kandoran, M.K. (1989)
    Fishery Technology
    An attitude scale was constructed to measure the attitude of fisherwomen towards improved fish processing methods. To construct the attitude scale, 'scale' and ‘Q’ values (the interquartile ranges) were calculated for 31 statements selected, based on the opinion of 34 judges. Based on the 'scale' and ‘Q’ values 16 statements were selected with eight favorable statements and eight unfavorable statements. The weightages given were 3, 2 and 1 for favorable statements and 1, 2 and 3 for unfavorable statements.
  • Inactivation of Vibrio parahaemolyticus in drinking water

    Sanjeev, S.; Mahadeva Iyer, K. (1989)
    Fishery Technology
    A study was conducted in the Cochin area of India to determine the effect of drinking water on Vibrio parahaemolyticus, a bacterium that contaminates fish harvested from marine and estuarine environments. Times of fresh-water exposure required to inactivate these bacteria are given. Findings indicate that the washing of fish and equipment used to handle the fish in drinking water may decrease in the number of viable Vibrio cells and thus aid in prevention of food poisoning.
  • Influence of dietary proteins on cholesterol levels in albino rats

    Ammu, K.; Stephen, J.; Devadasan, K. (1989)
    Fishery Technology
    Six groups of albino rats were fed identical diets, differing in their protein sources for sixty days. The protein sources used were fat free casein, defatted groundnut cake, and defatted fish powders from three species of fishes, namely, the fresh water fish Labeo rohita, the marine fishes, Rastrelliger kanagurta and Otolithus argenteus and marine prawns, Parapenaeopsis stylifera. After sixty days, the levels of cholesterol in the serum, liver and heart of the rats were estimated. The casein group recorded the highest level of cholesterol. Compared to casein, the groundnut protein was distinctly hypocholesterolemic. The fish proteins had a still greater cholesterol lowering ability. Of the proteins used in this study, the proteins of prawns had the maximum hypocholesterolemic effect. An attempt is made to correlate the behaviour of the proteins in this respect, with their respective amino acid compositions.

  • Preparation of mussel marinade

    Unnikrishnan Nair, T.S.; Joseph, K.G.; Muraleedharan, V.; Kalaimani, N. (1989)
    Fishery Technology
    A simple and cheap process for the preservation of mussel meat by marinading is described. The method involves blanching the mussel meat shucked from depurated live mussels in 3% boiling sodium chloride solution for 5 min followed by preserving it in a solution containing 3% acetic acid and 3% sodium chloride. The product stored in closed glass jars has a storage life of approximately 16 weeks at room temperature (23-30°C), after which the quality began to deteriorate. Texture of the meat is least affected and closely resembles that of the fresh meat.
  • Fish sauce from two species of unexploited deep sea fish Peristedion adeni and Peristedion weberi

    Lekshmy Nair, A.; Prabhu, P.V.; Shenoy, A.V. (1989)
    Fishery Technology
    Two species of unexploited deep sea fish Peristedion adeni and Peristedion weberi caught from the Exclusive Economic Zone of India were subjected to fermentation at ambient temperature (30 ± 2°C) in the presence of salt in 4:1 ratio. Periodical analysis of the fermented product was carried out up to one year. The sauces had brownish yellow colour and conformed to special grade of the standards prescribed by the Food and Drug Administration. Further solubilization of protein after 9 month's maturation was not appreciable.

    Basu, S.; Khasim, D.I.; Gupta, S.S.; Panduranga Rao, C.C. (1989)
    Fishery Technology
    Dry fish samples were procured from different fish markets and subjected to biochemical and bacteriological evaluation for assessing quality. The quality of market samples was compared with the samples dried in laboratory and in the mechanical drier [sic]. Most of the market samples had high moisture and sand contents. TVN values of market samples were high showing poor quality of the finished product.
  • Studies on canning Psenopsis cyanea

    Balachandran, K.K.; Vijayan, P.K. (1989)
    Fishery Technology
    Suitability of Psenopsis cyanea, a deep sea fish caught on board FORV Sagar Sampada from a depth of 350m off Cochin for processing into canned product was studied. The fish having high fat content around 52% (DWB) and white attractive meat renders itself well for canning yielding a product good in organoleptic characteristics. However to have a presentable appearance to the product the fish has to be skinned prior to canning. Gentle agitation of P. cyanea in 0.25% aqueous solution of lactic acid at ambient temperature for 15 min followed by thorough washing yields skinless fish. Fish suffers around 8% (DWB) fat loss during skinning. Fish canned in natural style and in brine have better organoleptic characteristics initially. On storage they develop slight rancidity. Fish canned in oil maintains the characteristics over a longer period.

The optimum girth/mesh perimeter ratio was found to be 1.31. A linear regression of G+0.445L=12.8 was fitted for conversion of length to girth.
  • Performance of 25m large mesh demersal trawl off Veraval, north west coast of India

    Kunjipalu, K.K.; Subramania Pillai, N.; Boopendranath, M.R. (1989)
    Fishery Technology
    Performance of a 25m large mesh demersal trawl, with 150mm mesh size in the fore parts of the trawl was evaluated in comparison with one boat high opening trawl of the Bay of Bengal Programme (BOBP) with 360 meshes of 160mm mesh size and 25.6m head rope length. An 8.2% increase in catch was obtained by 25m large mesh demersal trawl. The gear is comparatively cheaper, lighter in construction and offered better horizontal spread with significantly lower towing resistance. Commercial suitability of the gear for efficient harvesting of demersal fish resources of the region is discussed.
