Book Description
This book collects the available knowledge about the ecology of Atlantic salmon and contemporary stock assessment methods supporting the specific task of establishing reference points. Bayesian approaches for incorporating uncertainty are front and centre in the book. Stock and recruitment analysis methods, transport of reference points, risk analysis and use of index measures of abundance are presented in a format which can be readily understood and applied by scientists, educators, professionals and undergraduate students.

Book Description
This workshop stressed that the concept of reference points (RPs) needs to be closely connected to the management objective of concerned fisheries, taking into account various parameters such as maximum sustainable yield, economic and social benchmark and environment concern. Participants stressed the need to define different RPs for each dimension of management or to identify a single RP aimed at ensuring the sustainability of the system, thereby no longer limited to biological aspects. A review of possible approaches to setting RPs and indicators for Black Sea fisheries emphasized the dynamic nature of recent ecosystem changes. The traffic light approach was illustrated as a means of following dynamic changes and gaining a broad perspective on events at the ecosystem level. The workshop outlined the main RPs obtained by applying the bio-economic optimization models of effort and effort-catch as derived from the theory of population dynamics.

Book Description
"These guidelines aim to help those who design routine data collection programmes, focusing on the relationship between typical questions asked by policy-makers and managers, and the data required for providing reliable answers. Fisheries policy and management objectives, particularly under the precautionary approach, need to be based upon analyses of reliable data. Data are needed to make rational decisions, evaluate the fisheries performance in relation to management activities and fulfil regional requirements. These objectives are achieved using fishery performance indicators. Indicators are used to measure the state of the resource, the performance of fishing controls, economic efficiency, socio-economic performance and social continuity. The primary factor in choosing what data to collect is the link between the necessary operational, biological, economic and socio-cultural indicators and their associated variables. The way in which different data variables are collected needs tobe tailored to the structure of the fishery. The strategy will be strongly influenced by the budget and personnel available, and the degree to which fishers and others co-operate. The programme must identify which variables should be collected through complete enumeration and which can be sampled. Collection methods are influenced by the variable itself, the strategy, collection point and the skill of the enumerator. Once collected, fishery data must be stored securely, but made easily available for analysis, which is achieved through a computer-based data management system, following the basic data processing principles. The implementation of a data collection programme should follow a normal project cycle, developing a new legal and institutional framework as appropriate"--Abstract.

Book Description
Advances in Cephalopod Science: Biology, Ecology, Cultivation and Fisheries—volume 67 in the Advances in Marine Biology series—addresses major themes of growing research interest in the field of cephalopod research. The book is composed of four chapters incorporating the latest advances in biology, ecology, life cycles, cultivation, and fisheries of cephalopods. Each chapter is written by a team of internationally recognized authorities to reflect recent findings and understanding. The book represents a breakthrough contribution to the field of cephalopod science. Advances in Marine Biology was first published in 1963 under the founding editorship of Sir Frederick S. Russell, FRS. Now edited by Michael P. Lesser, with an internationally renowned editorial board, the serial publishes in-depth and up-to-date reviews on a wide range of topics that appeal to postgraduates and researchers in marine biology, fisheries science, ecology, zoology, and biological oceanography. Eclectic volumes in the series are supplemented by thematic volumes on such topics as the biology of calanoid copepods. Covers cephalopod culture Covers environmental effects on cephalopod population dynamics Covers biology, ecology and biodiversity of deep-sea cephalopods Covers life stage transitions in successful cephalopod life strategies
