Trade, Commerce, and the State in the Roman World


Book Description

This volume presents eighteen papers by leading Roman historians and archaeologists discussing trade in the Roman Empire during the period c.100 BC to AD 350. It focuses especially on the role of the Roman state in shaping the institutional framework for trade within and outside the empire, in taxing that trade, and in intervening in the markets to ensure the supply of particular commodities, especially for the city of Rome and for the army. As part of a novel interdisciplinary approach to the subject, the chapters address its myriad facets on the basis of broadly different sources of evidence: historical, papyrological, and archaeological. They are grouped into three sections, covering institutional factors (taxation, legal structures, market regulation, financial institutions); evidence for long-distance trade within the empire in wood, stone, glass, and pottery; and trade beyond the frontiers, with the east (as far as China), India, Arabia, the Red Sea, and the Sahara. Rome's external trade with realms to the east emerges as being of particular significance, but it is in the eastern part of the empire itself where the state appears to have adapted the mechanisms of taxation in collaboration with the elite holders of wealth to support its need for revenue. On the other hand, the price of that collaboration, which was in effect a fiscal partnership, ultimately led in the longer term in slightly different forms in the east and the west to a fundamental change in the political character of the empire.

Crustacean Farming


Book Description

Crustacean Farming: Ranching and Culture, Second edition. John F. Wickins and Daniel O'C Lee. The second edition of an extremely well-received book, Crustacean Farming, deals with all cultivated crustaceans of commercial significance, shrimp, prawns, crayfish, lobsters, crabs, and spiny lobsters, and examines the criteria by which both the feasibility and desirability of farming proposals are assessed. The characteristics and production methods of farmed and candidate crustacean species are described in sufficient detail to enable areas of profitable involvement to be distinguished form other opportunities presenting only very high risks and possibilities for serious loss. Coverage extends right from broodstock acquisition and management through to the operation of hatcheries, nurseries and on-growing units to key aspects of processing and marketing. New to this second edition are ranching and re-stocking operations together with the culture of ornamental shrimp and small crustaceans used as live food in fish and shellfish hatcheries. The sections on crustacean diseases, genetics and nutrition have been extended in the light of recent research advances. Examples of investment and operating costs of the different culture options are compared and an analysis of current trends in world crustacean markets is presented to assist in economic and financial appraisal. Special consideration is given to the place of crustacean farming within the economics of developing nations in relation to social and environmental impact in order to promote awareness of the wider implications of global developments. The consequences of recent research and technical developments are considered, together with concerns over genetic and animal welfare issues. Specific areas where further advances in technology are needed to improve the reliability or productivity of farming systems are highlighted. This important book is a vital tool and reference work for all those involved with crustacean farming worldwide.
