Abstract: 
Estuaries are the transitional zones of terrestrial and aquatic ecosystems along the coastal region which harbour several diversified species as they function as nursery and breeding grounds for many commercially important species. Data on fishing systems and fisheries resources of Bhayander estuary, an important estuarine ecosystem located in the Thane district of Maharashtra was collected from September 2016 to May 2017. Dol nets and gill nets are the major fishing gears operated in this estuary that supports the livelihood of fishers. The fishing season for bottom set lobster gill nets extended from January to May 2017 with the catch rate gradually declining towards May. Polyamide (PA) monofilaments of diameter 0.24 to 0.28 mm was used for the construction of bottom set gill nets. The average mesh size of the main webbing was 80 mm and the depth of operation ranged from 6-8m. Lobsters comprised 30% and crabs 14% of the total catch. Among lobsters, Panulirus polyphagus (Mud spiny lobster) and Panulirus ornatus (Ornate spiny lobster) and among crabs, Portunus pelagicus (Blue crab) and Portunus sanguinolentus (Three spot swimming crab) comprised the major catch. The paper highlights the design and catch composition of bottom set gill nets of Bhayander estuary
