| Abstract | This communication discusses various changes that have taken place in the material used, design aspects and operational methods of gillnets in coastal Kerala for the past three decades. Natural fibres have been replaced totally by man-made fibres. With the advent of motorization, fleet length of nets and range of operation have also been increased to cover deep and distant waters. The need for exploiting desired species resulted in the evolution of nets of suitable mesh size and twine size of varying thickness. The conventional single walled gillnets for crustaceans are gradually being replaced by multi-walled. Encircling gillnets for mackerel and sardine have given way to drift nets. |
