Effect of soil moisture and temperature on the severity of Macrophomina charcoal rot of sorghum

India is surrounded by seas and ocean on its three sides there is enough commercial potentiality for trading in fish and other aquatic animals. Fish statistics is subject to certain peculiar situations that stand in the way of accuracy of statistics of fish production. The fishing crafts are varied and changing. Statistical investigations of available marine fish production statistics for some economically important fish species has been undertaken using appropriate statistical methodology. There is no satisfactory system of obtaining information on fish production and its related observations. It required committed managerial effectiveness. Collection and investigation of statistics of fish production is as important as that for cereals and animal products. For cereals and animal products collection, investigation, experimentation and reporting using statistical methodology are well-organized throughout the country and the methodology is more or less standardized as relatively more importance is being given to these sectors since long. Though statistics of fish catch is being collected in different parts of the country for a number of years. Coverage area and reporting procedures in this sector need much more improvements. Statistics of marine fish production is generally collected species-wise, landing centre wise and season-wise from landing sites. Such data are then cumulated to district level data for reporting fish- production species-wise and season-wise. Information on variation of species-wise catches in different years, districts, seasons and their interactions are necessary for proper organization and improvement in fish trading. Such information has to be extracted through appropriate statistical investigation of available catch data. Due to high variation in prices and catch-magnitudes over the species of fish, it is necessary to make such studies specie's-wise (Annon, 1995, 1994-2002; Bal and Rao, 1990; Bsnnji, 1969 and Bapat andAlwani, 1973.).
