Book Description
Metamorphosis and the transition from larvae or embryos to juveniles in fishes are important in order to answer, for example, questions about: (1) life-history styles and their modifications in evolutionary perspective and within current environmental demands; (2) the development and application of fisheries recruitment models, (3) the use of ontogenetic scales for interspecific comparisons, (4) the identification of ontogenetic shifts in resource use, and (5) the discovery of evolutionary interrelationships of species or genera. This volume is dedicated to recent studies and reviews of existing knowledge on this insufficiently-addressed area of ichthyology. Most of the papers in this volume were presented in Bratislava, Slovakia, at the 1st International Workshop of the Fish Ontogeny Network of Europe (FONE) in September 1997, a meeting sponsored in part by the European Commission. This volume emphasizes an integrated approach to the study of fish ontogeny, which is a process during which one event is related to another and everything is related to everything else, encompassing physiology, morphology, behaviour and niche. Within this comprehensive perspective, the papers in this volume are grouped along four major themes: reflections on early ontogeny and metamorphosis, organism-environment relationships, ontogeny of predator-prey interactions, and behaviour and ontogeny. Among other issues, the papers consider topics such as whether one can identify when fish metamorphosis ends, whether the larva period begins with hatching or with the onset of exogenous feeding, whether fish ontogeny is `saltatory' or `gradual', and whether larvae are eliminated in some fishes with direct development. The keynote paper of this volume reviews the main topics within contemporary paradigms and the final paper concludes that the onset of the juvenile period can be identified in some species, but precision remains problematic, emphasizing the need for further research in this dynamic area of fish biology.

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
In autumn 2005 a second campaign of archaelogical research on the site of Stari Bar has been carried out. In agreement with the Montenegrin authorities (Museum of Bar - Town of Bar) the archaeological project involved the collaboration of the University of Ca' Foscari in Venice and Primorska University in Koper (Slovenia). While the team directed by prof. Mitja Gustin studied Ottoman pottery from the Museum and the storage area of the site of Bar, the team under my direction worked together with Mladen Zagarčanin of the Museum of Bar on the implementation of the archaeological research at the site. In this volume, a part of the results of that campaign are published. This book, like the first one on Stari Bar, remains a collection of papers. A group of articles focus on topics connected with the areas excavated in 2005 (UTS 45, UTS 112 and UTS 8b), a paper presents the archaeozoological analysis of context from the trench of 2004 (UTS 161) and another one gives a wide overview of stoneworking in Bar through the centuries. An article then aims to give a preliminary interpretation of the settlement sequence of the area, through the collation of new data and pre-existing archaeological knowledge. The team of 2005, under my direction, was constituted by Corinna Bagato, Fulvio Baudo, Diego Calaon, Erica D'Amico, Cristina Falla, Speranza Fresia, Alessandro Gasparin and Elena Grandi of the University of Ca' Foscari in Venice; by Mladen Zagarcanin of the Museum of Bar; by Aleksander Pluskowski and Krish Seetah of the University of Cambridge; by Milos Petrivecic of the University of Beograd. The project was funded by the European Union (Culture 2000. The Heritage of Serenissima), the Ministero degli Esteri Italiano (MAE) and by Region Veneto. In this occasion we want to express our gratitude to those that have helped and supported this mission also in 2005. For the Montenegrin side the Minister of Culture Mrs Vesna Kilibarda, the Chief of Cultural Heritage Mr Slobodan Mitrovic, the Mayor of the Municipality of Bar in 2005 Mrs Anka Vojvodic, the director of the Center for Culture of Bar Mr Milun Lutovac, the curator of the Museum of Bar Mr Vladislav Kasalika and the conservator of the archaeological area of Bar Mr Omer Perocevic. For the Italian side the Consul for Montenegro in 2005, Mrs Valentina Setta, the dean of the University Ca' Foscari Mr Pierfrancesco Ghetti, the functionaries of Regione Veneto, our colleague Gilberto Calderoni of the Laboratory of Earth Science of University 'La Sapienza' of Rome for the C14 analysis and our colleague Paolo Biagi of University of Ca' Foscari in Venice for his help with the micro-lithics of the site. This project enjoys the support of the Archaeological Society of Montenegro and was officially presented to the 4th Meeting on Montenegrin Archaeology (IV Skup. Dructvo Arheologja Crne Gore) held in Danilovgrad from the 18th to the 20th of October 2005. During the excavation we were visited by our friend Mr Mile Bakovic (Centra za arheologka istracivanja Crne Gore and now President of the Archaeological Society of Montenegro) and by Mr Djurge Jancovic (Faculty of Philosophy, Beograd). While finishing the preparation of this book we received the sad news of the sudden passing of our friend Milan Pravilovic, former President of the Archaeological Society of Montenegro and eminent scholar of Montenegrin archaeology. Milan repeatedly visited us on the excavation in Bar in 2004 and 2005, giving us many valuable suggestions and opinions. We are sure he would have supported us in the same way in the future. With affection and fondness we dedicate this volume to his memory. Sauro Gelichi Venice, August 2006

Book Description
Tilapia are sometimes known as "aquatic chicken" due to their high growth rates, adaptability to a wide range of environmental conditions, and ability to grow and reproduce in captivity and feed on low trophic levels. As a result, these fishes ahave become excellent candidates for aquaculture, especially in tropical and subtropical regions. Indeed, tilapia culture has been expanding rapidly, and is now practiced in more than one hundred countries worldwide. There is a large and growing literature on tilapia in specialist journals, but there have been few attempts to synthesize this by a single author. This book aims to fill this gap in the literature, by despcribing in detail the principles and practice of tilapia culture.
