Release Date: 2000
This manual defines methods for estimating selectivity of gillnet and longline gears, with particular reference to the use of these gears in abundance surveys. The manual illustrates how gear design, the basic concepts of size selection and fish morphometric data can be used to model selectivity. Statistical estimation methods are described in detail, and examples given of their application in spreadsheets.

This manual defines methods for estimating selectivity of gillnet and longline gears, with particular reference to the use of these gears in abundance surveys. The manual illustrates how gear design, the basic concepts of size selection and fish morphometric data can be used to model selectivity. Statistical estimation methods are described in detail, and examples given of their application in spreadsheets. The efficient use of these gears in abundance and research surveys is also discussed. Although the manual concentrates on gillnets and longlines, the methods given are general enough to be relevant to any research involving gear selectivity
The Montenegrin Adriatic Coast

Publisher: Springer Nature
Release Date: 2021-06-23
This is the first of two volumes that together provide an integrated picture of the Montenegrin Adriatic coast, presenting the natural components of the system as well as the chemical composition and chemical processes in the extended area. This book describes the biology and ecology of the high seas of the Montenegrin coast, with a special focus on their biodiversity, flora and fauna, fisheries, mariculture, marine reptiles and mammals. The data has been collected through national and international projects over the last few decades and provides the reader with models and recommendations for the protection of this vital region of the Adriatic coast, as well as scientific recommendations for the sustainable use of its biological resources. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
