This volume is a result of the survey on inland fishing gear and methods, conducted in Myanmar from September 2003 to December 2004. The survey locations are selected from Division and Districtwhere fisheries developed as shown in Figure     
     1. The abbreviations and symbols used in illustrations and the survey are in accordance with the use as the first, second, third and forth volumes ( Thailand, Malaysia, Philippines and Vietnam). The number of surveyed fishing gear types is shown in Table
     2 . The data, which are introduced in this monograph, were based on the practical surveys conducted by SEAFDEC and the Department of Fisheries, Inland Fishing Gear survey project team.

     1. Drawing of the horizontal length of seine net and gill net depends on the length of the float line, and vertical depth depends on the vertical hanging ratio of netting. In the case of gill net with side line, thedepth of the side line is drawn according to their length. Some types of fishing gear are shown by schemataor overall sketches with the dimensions indicated applicably.
     2. General outline drawings, such as the rig of a complete gear, and detailed drawings of components, are not to scale but the main dimension are given.
     3. Dimensions are given only in meter (m) and millimeters (mm). The units are not indicated but can easily be recognized, as follows:
     Meter         Length of float line and total length of gears etc., used with two decimals (e.g., 4.25, 25.30).
     Millimeter   Mesh size (stretched), diameters of rope, float, etc, used without a point or with one decimals only (e.g., 16, 135 or 12.5 ; 1.2).
     4. Mass and weight are indicated in the units of kilogram (kg) and gram (g). Buoyancies of floats and breaking load of netting yarns or ropes are shown by kilogram force (kgf) or gram-force(gf).
     5. Materials are indicated by abbreviations listed in appendix 1.
     6. The size of netting yarns is shown in the denier system.
     7. The mesh size, given in millimeters (mm) is understood to be the distance between the centers of the two opposite knots in the same mesh when fully stretched.
     8. The number of meshes in a straight row along the edges indicates the width and length or depth of net panels or sections.
     9. The term hanging ratio (E) designates the ratio between the length of a given portion of the mounting rope and the length of the stretched netting hung on this portion of the rope.
     10. Sequence in fishing operation is shown by sketches with circled Arabic number (1, 2 …), which indicate the sequence of operation stages.
     11. Parts of gear drawn in detail are indicated by circled capital letters ( A, B …).
