The present study is carried out to understand (i) the incidence and occurrence of species of Vibrio in different culture systems in and around Cochin, (ii) characteristics of vibrios isolates, their ecology including growth response to various hydrological parameters, sensitivity to about 40 antibiotics, and (iii) role of physico-chemical parameters in pathogenicity of vibrios, etc. and the results emerged from the investigations are important and encouraging for better understanding of the 'vibriosis' in the culture systems to develop remedial measures to control diseases. The Thesis begins with an “Introduction” followed by “A review of literature” on diseases of penaeid shrimps with particular reference to 'vibriosis' and “Material and methods” which details with the methods and procedures followed in the experiments and analyses of data. This Thesis consists of three chapters. Chapter Ideals with the incidence and ecology of Vibrio spp. in water, sediment and in juveniles of the Indian white prawn Penaeus indicus in the culture systems. In Chapter 2, characteristics of vibrio isolates including growth response to various levels oftemperature, salinity and pl 1, sensitivity to 40 antibiotics and minimal inhibitory concentration tests are detailed.e out-breaks. The Chapter 3 discusses the role of physico-chemical parameters in the incidence, seasonal abundance of Vibrio spp. and in 'vibriosis'. A summary of the whole work and list of references are also included at the end. This study gives a detailed information regarding the incidence and ecology of vibrios in the culture systems. their characteristics and pathogenicity

Recent studies with prawns indicate that their growth, metamorphosis, maturation and moulting are affected by the typo and level of lipids supplied in the diets. Despite the recognition of the importance of lipids in the diets of prawns there is no information on the essentiality and quantitative lipid requirements of Indian penaeid prawns. Therefore during the present study about 24 laboratory experiments were conducted to determine the essentiality and dietary requirements of total lipids, phoapholipida, fatty acids cholestrol, and to ascertain the nutritional value of natural lipid sources for the larvae, post-larvae tad juveniles of one of the most suitable cultivable species of panaeid prans. All the experiments were conducted in the laboratory following standard procedures, using isonitrogen and approaximately isocaloric purified diets. Changes were made in tha ingridients as required for specific requirements. For the larvae diets of particle size < 37) were fed, For the postlarvae and juveniles pellet feed was given. while data on survival and growth of larvae and pout-larvae 1-10 were recorded, data were collected on the survival, growth, food conversion ratio, protein efficiency ratio and biochemical composition at the body for post-larva 11-25 and juveniles. The influence ot fatty acid pattern of dietary lipid sources on the fatty acids profile of prawns were also studied in the case of juvenile prawns. Analysis of variance andleast significant differences test were employed to determine the significant differences between treatments in the observed parameters with the help of a newlett Packard master computer.

Seit einigen Jahren erfährt Lateinamerika einen epochalen Umbruch. Das neoliberale Modell ist in einer Krise. Die Politik des „Washington Consensus“ und das Diktum einer politisch nicht kontrollierbaren Globalisierung werden zunehmend hinterfagt. Aus der Linkswende haben sich neue alternative Politikkonzepten entwickelt. In dem vorliegenden Working Paper wird auf die Beziehung von sozialen Bewegungen, Ideologien und Regierungen eingegangen. In ihrer Diagnose arbeitet Maristella Svampa die ambivalenten Charakteristiken des aktuellen Wandels in Lateinamerika heraus. Daran schließt eine analytische Annäherung an die verschiedenen ideologischen Traditionen an, die den Widerstandssektor prägen. Abschließend werden bei der Analyse der vier wichtigsten Tendenzen einige der wichtigsten Daten über die Region präsentiert. Zu diesen Tendenzen gehören der Fortschritt der indigenen Kämpfe, die Konsolidierung neuer Formen des Kampfes, die Reaktivierung der national-populären Tradition, sowie die Rückkehr des „Desarrollismo“. Letztere wird sowohl von progressiven als auch eher konservativ-neoliberalen Regierungen unterstützt.
