his volume of Monograph Fishing Gear and Medthod in Southeast Asia : Cambodia was conducted in August 2003 with the aim to collect as many tyoes of fishing gear and medthod as possible. Most data were collected by interview fishermen with the help of questionnaire prepared inadvance
Though the surveyed area spanned along the coast line of Cambodia water, some of the gears were not found in the surveyes peroid (seemap. 1). Therefore, this volume of fishing gears in Cambodia would only be illustrated some parts of gears that were made and used at the time (see Tavle 18). Inorder to fulfill the completion, we best hope this volume will serve as the background knowledge for the future revistion
In the classification of fishing gera, drawing and explanations in this volume, we hope on the whole followed the system used in the "FAO Catalogue of Small-Scale Fishing Gear". The mode of presentation is summarized below.
1) Drawing of the horizontal length of surrounding nets, purse seine and gill nets is drawn according to the length of the float line, and the vertical depth according to the fully stretched. In the case of gill nets with sidelines, the depth is drawn according t theire length. The width of netting panels or sections of trawl gear is drawn according to half the streched netting, and the depth or lecgth according tofully stretched netting. Some gears are shown by schematic or partly perspective overall sketches, with dimensions indicated where applicable.
2) The general outline of drawings such as the rig of the complete gear and detailed drawings of components are mostly not to scale, but the main dimensions are given.
3) Dimensions are give only in meters (m) and millimeters (mm). Th units are not indicated but can easily be recognized, as followa:
Meters: legth of footropes, headlines, floatlines, etc. used with decimal of hundredths
4) Mass and weight are indicated in the units of kilogra (kg) and gram (g)
5) Materials are indicated by abbreviations list in Appendix1.
) The size of net yams is show in Denier unit.
7) The mesh size (in millimeters, mm) is understood to be the distance between the centers of the two opposite knots in the same mesh when fully streched.
8) The number of meshes in the staight row along the edges indicates the width and length or depth of net panels or sections.
9) The shape of netting section indicated by the cutting rate at its edge. A tabulation of common cutting rate for a practical range of taper ratios is shown Appendix2.
10) The rerm hanging ratio (E) designates the ratio between the length of a given portion of the mounting rope and the length of thestrtch netting hung on this portion on the rope.
11) When there are two or more variants in the construction of gear or manner of use, there are indicated in the title and opposite the drawing by Roman numerals (I,II,......). Where these variants refer to only one component part of gear, other possible ways of making this part are show with the abbreviation ALT.
12) Sequence in the fishing operation is shown by sketches with circled Arabic numerals (1, 2,...) which indicate the sequence of operation stages.
13) Part of gear drawn in detail are circled capital letters (A, B,...)
