- ItemPatenting Activities in Cage Culture – A Posteriori Approach(Society of Fisheries Technologists (India)Cochin, 2013)Cage aquaculture is growing fast, and various technologies have been developed in different countries of which many have been protected with some form of Intellectual Property Rights like patents. Objective of this study was to examine patenting activities in cage culture. For this, patent search was performed using commercial (Micropat) and free online (www.freepatentsonline.com) database. International Patent Classification code A01K61/ 00 and word search using Boolean operators were the focus of the search strategy. Information was also collected from Indian Patent Office (IPO) for the period 1910 to 2000. A total of 129 patents related to cage culture were found from 1970 to 2009. Out of these, 46 patents were granted in USA, 41 in Japan, 32 under World Intellectual Property Organization, nine in Europe and one in UK. Number of patents granted from 1970-1994 viz., pre Trade Related Intellectual Property Rights (TRIPS) era were 47 whereas from 1995 to 2009 (post TRIPS era), the number was 82 showing an increase of 74.5%. However, patenting activity has shown a decrease in 2000-2004 (25 patents) and in 2005-2009 (24 patents) compared to 1995-1999 during which maximum patents (33) were recorded. No conclusive reason could be reported for this. The patenting activities have to be documented and brought to broader notice, as cage culture is being given priority by nations across the world.
- ItemEconomic Losses due to Disease Incidences in Shrimp Farms of India(Society of Fisheries Technologists (India)Cochin, 2013)Huge economic losses occur due to incidence of viral and other diseases in shrimp farms of India. To make a quantified assessment of these losses, a field survey of 1142 shrimp farms following a statistical random sampling from nine coastal states during the period 2006-08 was conducted. The gross national losses in the country due to shrimp diseases was estimated as 48717 metric t of shrimp valued at Rs. 1022.1 crores, and employment of 2.15 million man days. Epidemic seriousness among the diseases was for White Spot Syndrome Virus (WSSV), Loose Shell Syndrome (LSS) and combination of WSSV and LSS, white gut and slow growth syndrome in that order at national level. Additional price loss was also recorded on account of poor quality of final output like deformed organs, loose shell and muddy smell. In some cases, farmers resorted to premature harvest and hence the production biomass also reduced coupled with price drop according to the count per kg of shrimps.
- ItemA High Performance Liquid Chromatographic Method for Quantitative Determination of Tetracyclines and its Epimers in Shrimp Muscle(Society of Fisheries Technologists (India)Cochin, 2013)A method for determination of tetracycline, oxytetracycline, chlortetracycline, 4-epitetracycline, 4- epioxytetracycline and 4-epichlortetracycline in shrimp muscle tissue by high performance liquid chromatographic method (HPLC) with a UV detector is described. The method involves extraction of the analytes by McIlvaine buffer, clean up by C18 SPE cartridge and analysis by HPLC and UV detection. A good separation of all the six analytes was achieved and good recovery (58 to 89%), repeatability and within laboratory reproducibility were possible with this method.
- ItemEvaluation of Fish Curry from Farmed and Wild Caught Indian Major Carps of Tarai Region, Uttarakhand(Society of Fisheries Technologists (India)Cochin, 2013)The differences between pond cultured and naturally occurring (wild) Indian major carps (Catla catla, Labeo rohita, Cirrhinus mrigala) from the reservoirs in terms of proximate composition of the fishes and sensory evaluation of fish curry made out of them are presented in this communication. Comparatively higher protein and ash but lower fat and carbohydrate were observed in wild fish species. The cultured fishes possessed high moisture and fat content. The panelist choice went in favour of fish curry prepared from Labeo rohita. There was superior preference for curry prepared from the wild fish over the cultured fish owing to stronger texture, required elasticity of chewing, pleasant taste and more delicious flavor. The results clearly indicate that wild fish is preferable to cultured fish due to firm texture, excellent affable taste and flavour.
- ItemCryoprotective Effect of Shrimp Waste Protein Hydrolysate on Croaker Surimi Protein and Gel Characteristics during Frozen Storage(Society of Fisheries Technologists (India)Cochin, 2013)Effect of shrimp waste protein hydrolysate (SWPH, 7.5% dried matter, T2) on quality of Croaker fish surimi protein was examined in terms of nitrogeneous parameters, myosin and actin degradation, Ca2+-ATPase activity and unfrozen water content in comparison to surimi with sucrosesorbitol blend (T1) and control (C, no additive) during frozen storage for 120 days at -25oC. Significant variation (p<0.05) of these parameters between storage days and difference of T1 and T2 sample from control suggested muscle protein as succeptible to freeze denaturation and application of SWPH as an alternative cryoprotectant to sucrosesorbitol (SuSo). Textural properties including gel strength, hardness, cohesiveness, springiness, chewiness and gumminess of kamaboko gel prepared from surimi samples decreased with storage days though SWPH was efficient enough to reduce effect of freeze denaturation on gel characteristics during initial three months of storage.
