Book Description
This handbook summarises the experience gained over recent years in fishery statistical development by the Fishery Information, Data and Statistics Unit of the FAO, and provides guidance for developing and implementing cost-effective and sustainable fishery surveys. The methodological and operational concepts discussed apply equally to marine and inland capture fisheries. The emphasis is placed on the understanding and interpretation of the statistics, rather than on the computations producing them.

Book Description
Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Book Description
This is a report on the guidance given to fisheries data-managers on improving their collecting, processing, storage and reporting capabilities of information on the status and trends of their marine capture fisheries, provided by the CARICOM Fisheries Unit and the FAO. There was also proposals and discussion on expanding the data collection on national fisheries to include social and economic information.

Book Description
This paper considers issues of sampling accuracy when sample-based data collection operations are performed under operational constraints, a concern of fishery administrations with limited budgets and human resources. It focuses on the determination of safe sample size using classical statistical methods in light of specific target populations. The concepts and methods discussed apply equally to both marine and inland capture fisheries, and can be adapted to commonly used data collection systems.

Book Description
This manual deals with the practical implementation of a routine data collection programme. The data collection programme is developed through a top-down approach, from the identification of the objectives down to the practical recording and management of data obtained from the fishery. The issues are dealth with both through detailed discussion and by using simple examples. The examples are mostly based on situations in tropical fisheries, and in particular, experience has been drawn from developing a data collection programme in Viet Nam. The main questions addressed i n the manual are which fisheries data to collect, where and when to collect them. Only data from commercial marine capture fisheries are considered. The methodologies used are mainly appropriate for a tropical, developing county, with many small (artisanal) vessels and a few large (industrial) vessels. The methodology is the "sample-based approach". The data collection methodology presented attempts to utilize whatever information can be obtained in practice in a developing country.

Book Description
This text brings together important ideas on the model-based approach to sample survey, which has been developed over the last twenty years. Suitable for graduate students and professional statisticians, it moves from basic ideas fundamental to sampling to more rigorous mathematical modelling and data analysis and includes exercises and solutions.

Book Description
For two decades the idea of governments and fishers working together to manage fisheries has been advocated, questioned, disparaged and, most importantly, attempted in fisheries from North and South America through Europe, Africa, Asia and Oceania. This book is the first time these experiences have been pulled together in a single volume, summarized and explained. The Fisheries Co-management Experience begins with a review of the intellectual foundations of the co-management idea from several professional perspectives. Next, fisheries researchers from six global regions describe what has been happening on the ground in their area. Finally, the volume offers a set of reflections by some of the best authors in the field. The end result describes both the state-of-the-art and emerging issues for one of the most important trends in natural resources management.

Book Description
The National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Administration (NOAA) is responsible for collecting information on marine recreational angling. It does so principally through the Marine Recreational Information Program (MRIP), a survey program that consists of an in-person survey at fishing access sites and a mail survey, in addition to other complementary or alternative surveys. Data collected from anglers through MRIP supply fisheries managers with essential information for assessing fish stocks. In 2006, the National Research Council provided an evaluation of MRIP's predecessor, the Marine Recreational Fisheries Statistics Survey (MRFSS). That review, Review of Recreational Fisheries Survey Methods, presented conclusions and recommendations in six categories: sampling issues; statistical estimation issues; human dimensions; program management and support; communication and outreach; and general recommendations. After spending nearly a decade addressing the recommendations, NMFS requested another evaluation of its modified survey program (MRIP). This report, the result of that evaluation, serves as a 10-year progress report. It recognizes the progress that NMFS has made, including major improvements in the statistical soundness of its survey designs, and also highlights some remaining challenges and provides recommendations for addressing them.

Book Description
This manual contains guidance on data collection methods for developing socio-economic indicators, and it can be used to facilitate and simplify reporting under international conventions and agreements on matters relating to the sustainable fisheries development. The methodologies can be applied to fisheries at many different levels, from individual fisheries and coastal management units to a global level, and it aims to encourage consistent use of statistical methods in data collection.
