Book Synopsis Manual on Sample-based Data Collection for Fisheries Assessment by : Per Sparre
Download or read book Manual on Sample-based Data Collection for Fisheries Assessment written by Per Sparre and published by Food & Agriculture Org.. This book was released on 2000 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Sampling Methods Applied to Fisheries Science by : Emygdio L. Cadima
Download or read book Sampling Methods Applied to Fisheries Science written by Emygdio L. Cadima and published by Food & Agriculture Org.. This book was released on 2005 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this manual is to present the basic and standard concepts of sampling methods applied to fisheries science. In order to ensure sound fisheries research, it is essential to have reliable data from landing ports, fishery stocks and research surveys. A rational management of fishing resources can then be established to ensure a sustainable exploitation rate and responsible fisheries management, providing long-term benefits for all. This document provides an introduction to sampling theory and introduces the theory of the three worlds (population, sample and sampling), as well as a short revision of probability concepts. It also provides an overview of the simple random, random stratified, cluster and two-stage sampling methods. The expressions for estimating the mean and total of the populations, their sampling distributions, the expected values, the sampling variances and their estimates are included and justified for each of the sampling designs. The document also contains a case study of biological sampling from landing ports and exercises that should be used to further understanding of the objectives of sampling and its advantages for fishery resource studies.

Book Synopsis Sampling Statistics in the Atlantic Menhaden Fishery by : Alexander J. Chester
Download or read book Sampling Statistics in the Atlantic Menhaden Fishery written by Alexander J. Chester and published by . This book was released on 1984 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic menhaden, Brevootia tyrannus, the object of a major purse-seine fishery along the U.S. east coast, are landed at plants from northern Florida to central Maine. The National Marine Fisheries Service has sampled these landings since 1955 for length, weight, and age. Together with records of landings at each plant, the samples are used to estimate numbers of fish landed at each age. This report analyzes the sampling design in terms of probability sampling theory. The design is classified as two-stage cluster sampling, the first stage consisting of purse-seine sets randomly selected from the population of all sets landed, and the second state consisting of fish randomly selected from each sample set. Implicit assumptions of this design are discussed with special attention to current sampling procedures. Methods are developed for estimating mean fish weight, numbers of fish landed, and age composition of the catch, with approximate 95% confidence intervals. Based on specific results from three ports (Port Monmouth, N.J., Reedville, Va., and Beaufort, N.C.) for the 1979 fishing season, recommendations are made for improving sampling procedures to comply more exactly with assumptions of the sampling design. These recommendations include adopting more formal methods for randomizing set and fish selection, increasing the number of sets sampled, considering the bias introduced by unequal set sizes, and developing methods to optimize the use of funds and personnel.

Book Synopsis Handbook for data collection on recreational fisheries in the Mediterranean and the Black Sea by : Grati, F., Carlson, A., Carpentieri, P. & Cerri, J.
Download or read book Handbook for data collection on recreational fisheries in the Mediterranean and the Black Sea written by Grati, F., Carlson, A., Carpentieri, P. & Cerri, J. and published by Food & Agriculture Org.. This book was released on 2021-07-06 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine recreational fisheries are an integral part of Mediterranean and Black Sea coastal life and are commonly practiced throughout the region. Recreational fisheries also represent an important driver of coastal tourism, which constitutes one of the region’s most important maritime sectors in terms of gross value added and employment. However, despite their ubiquity and potential socio-economic contribution, recreational fisheries are a data-poor sector and can vary widely from one country to another, thus impairing proper consideration of the recreational fisheries sector in policy-making and undermining efforts towards sustainable fisheries management at the regional level. The main goal of this handbook is therefore to provide a clear methodological framework to allow Mediterranean and Black Sea countries to implement suitably harmonized sampling and survey monitoring schemes for recreational fisheries. This handbook establishes a minimum set of necessary information for monitoring recreational fisheries, while, at the same time, allowing for flexibility to accommodate national specificities and data collection needs. It also provide guidance on the data analysis process as well as advice to successfully engage stakeholders in the data collection process.
