Book Description
The thirteen papers presented in this publication review fish stocks and fisheries of mountainous areas of Asia: Himalayas (Bhutan, Nepal, northern states of India within the Himalayas), Western Ghats (India), Karakoram-Hindu Kush (Pakistan, Afghanistan), Pamir (Tajikistan), Tien Shan (Kyrgyzstan, Kazakhstan), Altai (Kazakhstan, Mongolia, China), high altitude lakes of Mongolia and those of western China (provinces of Qinghai and Xinjiang [Uighur Autonomous Region] and Xizang [Tibet Autonomous Region]) and Caucasus (Armenia, Georgia, Azerbaijan). From south to north, fish fauna complexes change from Oriental to Palaearctic. Cool and coldwater streams and rivers support subsistence and/or recreational/sport fisheries, with commercial fisheries practised only in some lakes and reservoirs. While fishing of streams and rivers is largely unmanaged, considerable management effort has gone into some lakes and reservoirs, especially in Kazakhstan, Kyrgyzstan and India in order to maintain reasonably high fish catches. The management measures have included translocation and stocking of exotic fish species and regulation of fisheries. For recreational fishery, brown trout has been stocked in rivers and streams of the southern slopes of Himalayas, rainbow trout in some streams of Western Ghats ... etc.

Book Description
“Traveling with Steller as he botanizes his way across Siberia is part wilderness adventure, part open air museum visit, and a valuable historical window.” —Erika Monahan, author of The Merchants of Siberia In the winter of 1739, Georg Steller received word from Empress Anna of Russia that he was to embark on a secret expedition to the far reaches of Siberia as a member of the Great Northern Expedition. While searching for economic possibilities and strategic advantages, Steller was to send back descriptions of everything he saw. The Empress’s instructions were detailed, from requests for a preserved whale brain to observing the child-rearing customs of local peoples, and Steller met the task with dedication, bravery, and a good measure of humor. In the name of science, Steller and his comrades confronted horse-swallowing bogs, leaped across ice floes, and survived countless close calls in their exploration of an unforgiving environment. Not stopping at lists of fishes, birds, and mammals, Steller also details the villages and the lives of those living there, from vice-governors to prostitutes. His writings rail against government corruption and the misuse of power while describing with empathy the lives of the poor and forgotten, with special attention toward Native peoples. “Not only showcases Steller the botanist but also reveals him as an admirable human being with a great sense of humor who managed to keep an upbeat attitude in the most trying circumstances.” —Eckehart J. Jäger “What emerges is a remarkable window into life—both human and animal—in 18th century Siberia.” —The Birdbooker Report “Adds fascinating details to the life of Steller and his travels and discoveries just before joining Bering in Kamchatka to set sail.” —Anchorage Daily News

Book Description
Chemometrics is the chemical discipline that uses mathematical, statistical and other methods employing formal logic: to design or select optimal measurement procedures and experiments, and -- to provide maximum relevant chemical information by analysing chemical data. Being conceived as a branch of analytical chemistry, chemometrics now is a general approach. It extracts relevant information out of measured data, regardless of their origin: chemical, physical, biological, etc. Chemometrics has been applied in different areas, and most successfully in multivariate calibration, pattern recognition, classification and discriminant analysis, multivariate modelling, and monitoring of processes. The main chemometric principle is a concept of hidden data structures that can be found using methods of multivariate data analysis. These are the well-known statistic tools such as partial least squares (PLS), soft independent modelling of class analogy (SIMCA), principal-component regression (PCR), wavelet analysis, and many others. Current activities of chemometricians fall into two main categories: (1) development of new methods for manipulating multivariate data and (2) new applications of the known chemometric techniques in different areas such as environment control, food industry, agriculture, medicine, and engineering.

Book Description
The Russian Federation is the largest country in the world occupying one-third of Eurasia and it has enormous water resources. [Author] Fish from inland waters has always been a central part of the Russian diet and a major contributor to national food security. [Author] Inland fisheries are highly diversified and provide employment to 40 500 fishers in industrial fisheries. [Author] In addition an estimated 2. [Author]4 million amateur and recreational fishers and around 150 000 Indigenous Peoples fish for subsistence and small-scale trade. [Author] Historic production figures surpassed 500 000 tonnes of fish from Russian inland fisheries, but have declined over the last 40 years, and current official catches are around 270 000 tonnes. [Author] However, unrecorded catches by recreational/amateur fishers add up to an estimated 100 000 tonnes annually, and subsistence catches by Indigenous Peoples probably add another 67 000 tonnes; and finally, illegal catches may add another 50 000 tonnes, suggesting that total landings are not far from what was caught in the past. [Author] The Russian Federation has invested significant resources and efforts into developing and managing inland fisheries and aquaculture. [Author] The review presents the current management structure and summarizes the comprehensive legislation governing inland fisheries, including the agreements with neighbouring countries sharing some of the major waterbodies or rivers.
