Gill nets are one of the predominantly used fishing gears of Assam in the rivers and flood plain wet lands (beels). Results of a study on the gill nets of Assam undertaken during 2004-2006 are reported in this paper. Gill nets of different mesh sizes ranging from 20 to 320 mm targeted at different groups of fishes are prevalent in Assam. The technical specifications, salient features and operational aspects of different gill nets are discussed. The nets are classified into groups based on the mode of operation, species of fish caught and materials used for construction. Synthetic materials like polyamide has almost completely replaced the natural fibres in gill nets and polyamide monofilament yarn of 0.16 to 0.20 mm dia are being widely used in the state.
