FISHING GEAR AND METHODS IN SOUTHEAST ASIA: IV. VIET NAM
Vietnamese Fisheries has many favorable conditions for development due to the coastline of 3,260 km and abundant marine resources. The number of fishing boats increases ceaselessly and the types of fishing gears are diversified. The sizes and designs of fishing gears depend on fishing methods, boat sizes, conditions, fishing ground and the habits of fishermen in each region, so there are lots of different types. Therefore, it is necessary to design the Monograph of Fishing Gears and Methods to make know widely the structure of fishing gears with high fishing efficiency for common application. Also, the design of the Monograph produces management measures and limits the practices of destructive fishing gears and methods. The Ministry of Fisheries of Vietnam entrusted Nha Trang University of Fisheries and the Research Institute of Marine Products to carry out the subject "Designing Monograph of Fishing Gears in Vietnam" in 1997. However, this work has not fully reflected the types of fishing gears as well as fishing techniques. In order to contribute to the design of the overall picture of fishing gears and fishing techniques of the Southeast Asia, some experienced research staff form the Research Institute of Marine Fisheries implemented the surveys of fishing gears in coastal provinces, then processed data, designed monographs and finished the work on fishing gears and methods of Vietnam. The publication have used some designs of fishing gear in monograph of 1997 and it consists of 10 parts, each part shows fishing operation, characteristics and drawing of typical fishing gear samples of each group, such as trawl net, surrounding net, gill net, hook and line and others. In this volume, we are only able to present the samples of fishing gears which are most commonly used and have high fishing catch and economic efficiency of some key fisheries areas in Vietnam. With a view to reading easily, symbols written in the drawing are in accordance with the regional common regulations. Hopefully, the information in the publication will be scientific base and useful reference material for designers and uses of fishing gears in Vietnam and other countries in the region. During the preparation, because of the restriction in some aspects, there are some shortcomings in this book. We are very pleased to receive your suggestions.
