- ItemIncidence of cadmium in processed products of cephalopods from gujarat, india(Society of Fisheries Technologists(India),Cochin, 2003) Zynudheen, A.A.; Ninan, G.; Sen, A.; Badonia, R.The presence of high levels of toxic heavy metals in marine products is a matter of concern for the consumers and authorities as they cause serious health hazards. The quality standards adopted by the importing countries, necessitates regular monitoring of these metals. Cephalopods and their products from India enjoy a high demand in the international market, especially Europe and America. The state of Gujarat, particularly Saurashtra coast contributes a major share of the cephalopod products exported from the country. About 20 different types of cephalopod products are exported from this region. The levels of Cadmium in fresh and frozen squid and cuttlefish in whole and in different product forms from the industries of Saurashtra region were determined. Among the different product" about 20% of whole cuttlefish samples and tentacles showed cadmium levels above the permissible limits of 2 ppm, which implies the necessity of proper cleaning procedures during the processing stage.
- ItemMonoclonal antibodies - prospects and applications(Fishery Survey of India, Mumbai (India), 2004) Sen, A.; Zynudheen, A.A.; Ravishankar, C.N.; Kumar, K.A.; Badonia, R.; Solanki, K.K.It is becoming increasingly important to screen for marine pathogens, using diagnostic tests which are both reliable, quick and inexpensive. Conventional procedures of isolating and characterizing micro-organisms are both time consuming and expensive. It is to be stressed that diagnostic tests for detection of fish pathogen and also for spoilage causing organisms, should be rapid, simple and reliable. Serology has to a great extent simplified monitoring and detection procedures of most pathogenic micro-organisms. Serological tests are now being used on a routine basis for disease diagnosis all over the world, both for human beings and for animals. Conventional serological tests however used polyclonal antisera, which has very little avidity pertaining to immunoglobulin binding. In other words the specific antibodies represent a diverse spectrum of molecules with different avidities (binding capacities), directed against different epitopes of the antigen. This could lead to several problems viz; cross reactivity, less specificity, batch to batch variation in results etc. The technique of monoclonal antibodies has revolutionized several areas of modern biological research. Monoclonal antibodies are finding increasing use in disease diagnosis and pathogen detection. They are produced by immortal clones of cells called 'Hybridomas'. They are identical with respect to several useful parameters viz; IgG subclass, allotype, variable regions, structure, idiotype, affinity and specificity for a given epitope. In using a polyclonal antiserum, the binding of non-specific IgG relative to antigen specific IgG may be uncomfortably high. This problem is greatly reduced with a monoclonal antibody leading to a much higher signal to noise ratio. A monoclonal antibody is capable of being applied in a variety of serological tests.
- ItemA perspective on the fish meal industry in Gujarat(Society of Fisheries Technologists(India),Cochin, 2003) Sen, A.; Parmar, H.; Badonia, R.; Nair, K.G.R.About 40,000- 50,000 t of fish meal is produced annually in Gujarat.fish meal is a nutritious and widely used feed supplement rich in protein and b vitamins.by catch derived from malti-day fishing trips.which is poor in quality,is presently being used as the raw material for producing fish meal.the availability of low cost fish or less utilized fish species is on the decline due to various reasons.the main constituents of by catch are juveniles of fishes like Ribbonfish,Sciaenids,perches and other tablefishes,shrimps,anchovies ,squilla,pufferfish,crabs,etc.in the winter months,puffrfish,crabs,and squilla contribute nearly 50%of the total bycatch .this leads to an increase in the salt content in the final product.the presence of puffer fish in the by catch could also leads to toxin related problems in the live stocks. apart from the bycatch,the wastes generated from the processing industry are also used for the purpose.however due to the poor quality of raw material and lack of organized activity in this sector,,the desirable quality of fish meal is not attained.A process has been developed for improving the quality of fish meal by controlled fermentation,accompanied by mineral and the pro biotic fortification.The main benefits of this types of fish meal are improved keeping quality due to the dominating pro biotic fer mentors that inhibit oxidative and autolytic changes in protein and lipid,improved palatabilty,presence of restorative pro biotic bacteria,availability of micro nutrients and lower risk of pathogens like salmonella.the technique is low cost and could be easily adapted by the fish meal manufactures.this paper deals with the present status of fish meal industry in Gujarat and its future prospects.
- ItemTrends in fish processing and quality assurance in Gujarat(Society of Fisheries Technologists (India), Cochin, 2003) Badonia, R.; Sen, A.; Devadasan, K.Gujarat is a leading state in marine fish production and export . Recent fish produclion of the state is over 0.65 million tonnes and export over Rs. 6000 million. The sLate is leading in export of fish such as squid. cuttlefish and surimi. Contrary to general perception. per capita fish consumption in the state is 7.77 kg.yr•1• double that of national average. Dried fish and lishmeal accounts for over 55% of the fish production. The freshwater aquaculture holds good prospects in the state. Processing practices, i mportant fish and fishery products, and major quality problems in the state. are discussed in this paper. Need for prawn culture, maketing of freshwater fishes, l ive fishes and shellfishes are highlighted. The paper stresses the need to realise the potential for internal marketing and export of d ried fish and byproducts.
- ItemUtilization of jawla (acetes spp)(Society of Fisheries Technologists(India),Cochin, 1998) Zynudheen, A.A.; Sen, A.; Ravishankar, C.N.; Kumar, K.A.; Badonia, R.; Solanki, K.K.Dried jawla (Acetes spp) was processed in the laboratory and its chemical and bacteriological qualities were compared with those of commercial samples. Both products were bacteriologically sound but the latter was contaminated with extraneous matter. Various products like wafer, soup powder, cutlet, spiral and squid stuffed with jawla were prepared and their sensory qualities were evaluated. The studies showed that all products were acceptable.
