Book Description
The fourteenth session of the European Inland Fisheries Advisory Commission (EIFAC)was held in Bordeaux from 27 May to 3 June 1986. The session reviewed EIFAC activities since 1984 in the fields of fishery biology and management, fish culture and diseases and water pollution control. EIFAC decided its future programme of work and in particular the activities which should be carried out until the session scheduled to take place in Sweden in 1988.

Book Description
Due to the recent rapid development of freshwater aquaculture in the Caucasus Region, many new and previously known fish diseases have appeared. One of the most prominent features of the region’s aquaculture is that it is mostly based on the rearing of cyprinids, mainly the common carp (Cyprinus carpio), as well as a few other predatory fish species. As a result, this book focuses on the diseases that affect these and other important warmwater fish species. Although this field guide covers the diseases of warmwater fish of Central and Eastern Europe, the Caucasus and Central Asia, it also draws upon the extensive knowledge base available for the countries of Central Europe and the former Soviet Union, as well as recent research findings from the Islamic Republic of Iran and from Turkey. The major warmwater fish species cultured in the region and their health status are discussed, and two major categories of disease are recognized: biotic and abiotic diseases. Although there are numerous biotic diseases, abiotic factors (e.g. lack of oxygen, temperature, feeding mistakes) remain the main cause of losses in aquaculture. The best practices for the field and laboratory examination of disease outbreaks are reviewed, and the importance of accurate and detailed data recording emphasized. Prevention as a key factor in avoiding the spread of disease is highlighted, and actions to prevent the spread of diseases between farms, regions, countries and continents are discussed. Possible methods for the treatment of each disease are reviewed; unfortunately, the chemicals available for use in aquaculture are now rather limited, as many of them are hazardous to both the environment and human health. Of the viral diseases discussed, spring viraemia of carp (SVC) and koi herpesvirus (KHV) pose the greatest threats to the world’s carp populations. Of the bacterial diseases, ulcer disease is still the main problem in carp culture, while among the parasites, Ichthyophthirius multifiliis, the cause of white spot disease, is among the most important. Exotic parasites such as various Thelohanellus species, as well as tapeworms belonging to the genera Bothriocephalus and Khawia, are responsible for a considerable amount of damage. Some diseases of unknown aetiology are also discussed.

Book Description
Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

Book Description
This document deals with the problems of fish culture, particularly carp, in eastern Europe. It reviews the types, methodology and role of fish culture and the economic analysis of this activity. It shows that there is no universal method for economic analysis of fish culture, especially if it has to be used for comparing economic efficiency of fish farming activities, and presents a general simplified outline of feasible economic analysis.

Book Description
The European Inland Fisheries Advisory Commission organized on 29-30 May 1980 a symposium on new developments in the utilization of heated effluents and of recirculation systems for intensive aquaculture, in Stavanger, Norway. There were six consecutive technical sessions during which the various topics were introduced and discussed. These topics referred to water quality, engineering/technology of equipment facilities, biology of cultured organisms, management/economics of rearing systems and socio-economics. A series of recommendations were made, six of them being later endorsed by the Commission at its Eleventh Session. These include (i) the establishment of a working party to analyze the problems related to fish farms effluents (ii) the activation of a correspondence group to propose terminology, format and units of measurement related to flow-through systems and to recirculation systems (iii) the preparation of a code of practice on the introduction of non-indigenous species.
