Anglers passionately hunt for this Tiger of water, a thrilling sport & cherish a photograph with it. True to its name the Golden Mahseer, is a pleasure to view because of its size and colours on back, sides and the fins. The species (endemic to Himalaya) has never been promoted for the sport quality, except in the northeast by Jia Bhoreli Assam Angling Association. The threats to this species due hydro-power needs of India, Nepal and adjoining countries, have rapidly increased over the last decade. The series of barrages and dams on a single river will severely fragment its habitat. Regulation and linking of rivers in the Himalaya will adversely endanger this species. The magnificent fish deserves a better world, and needs attention on the lines of Project Tiger to prevent its extinction in the Himalaya. Its cousins in the Peninsular India are in a little better condition. This document will be the basis for action by concerned institutions & is a hope to redeem its glory thru increased awareness. ····· 1036198488

It is an important disease of cattle and buffaloes. In Pakistan, during the year 2005-06, Cattle population was 25.5 millions, while buffalo s population was 28.4 million. Within the livestock sector, milk is the largest and the single most important commodity. Despite decades of neglect, Pakistan is the fifth largest milk producer in the world (Anonymous, 2006). Production of high-quality milk is a high-priority issue for dairy farmers and milk processors. The investigation of mastitis problems on dairy farms is an area of increasing demand and is an ideal way for veterinary practitioners to increase involvement in production medicine programs (Ruegg, 2003). The prevalence of mastitis was significantly higher in the early lactation stage than in the mid-lactation stage, in cows with lesions and/or tick infestation on skin of udder and/or teats than in cows without this factor, and in the wet season than in the dry season.

About 134 species of arthropods were found to be associated with the cotton crop in Punjab,of which bollworms cause serious damage. Among the bollworms, Helicoverpa armigera is a very serious polyphagous pest.Biological,cultural and chemical methods have been used to attempt its control.The extensive and indiscriminate use of conventional insecticides as well as synthetic pyrethroids against H. armigera has resulted in development of resistance to various insecticides.A novel method of controlling this pest is use of Bt cry toxin from a soil bacterium,Bacillus thuringiensis (Bt).Since its release has been able to reduce the use of chemical insecticide, thereby lowering the risks pertaining to environmental hazards, human health and production costs.The insertion of an additional Bt gene encoding for a different toxin (Cry2Ab) into current Bt cotton cultivars containing cry1Ac gene may provide additional activity on lepidopteran pests and would improve pest control value. ····· 1036198346

The forests are assumed to be treated in an exemplary manner and wood production is assumed to be efficient. In reality, forestry in Finland is in a state of chaos, both as a commercial business activity and as regards forest treatment. The present research undertaking looks into the causes behind the skewed development of forestry in Finland. It also explores the matter of why this skewedness has not been examined. The main causes found are the corporative system of administration in forestry and the Finnish foresters` professional culture. Finnish foresters have been given more or less unlimited powers in guiding forestry, and they have done so from a cultural base characterised by anti-farming attitudes, inadequate business economics expertise, and societal blindness. As a result, a globally unique system of totalitarian corporatism has come into being, a system resembling the socialist system of society. This research endeavours to arouse decision-makers in Finnish forest policy to take steps aimed at making the forestry a productive livelihood once again. ····· 1036192617
