The accurate identification of fish 'ear-bones', known as otoliths, is essential to determine the fish prey of marine and terrestrial predators. Fish otoliths are species-specific when combining size, shape and surface features, and can remain undigested for long periods. As a result, they can indicate which fish make up the diet of various predators, including cephalopod, seabird, marine mammal and fish species. Such studies are crucial for understanding marine ecosystems, and trophodynamics in particular. Increasingly, these methods are being used to understand the diet of some terrestrial predators, also extending to that of humans in archaelogical studies.
The present technical manual is divided into nine chapters, encompassing a wide range of managerial aspects commonly encountered in a fish farm. It is not directly subjective; rather the main strategy is to provide knowledge through problem-solution oriented approach and practical field experiences. The methodologies adopted and discussed in this technical manual are strictly field oriented and region specific. This manual will prove to be quite handy as a quick reference guide for fishery professionals, progressive aqua-famers, fish culture enthusiasts and amateur researchers who are working at the field level.
John Fisher was central to the issues and dilemmas of the renaissance and the reformation in Tudor England. Active as a humanist, preacher, bishop, educationalist and controversial theologian, Fisher demonstrated the rich life of the pre-reformation church as well as its problems in confronting the 'blind and disordered desire' of Henry VIII. For Fisher, as for Thomas More, this resulted in execution on Tower Hill. This study focuses on Fisher's wide-ranging pastoral, scholarly, literary and political activity, which makes him a key figure in European religious and cultural history. The title of this book is based on Fisher's personal motto - Christ's words to the apostles, 'I will make you to be fishers of men' (Matthew, 4:19).
