Inland open water fisheries provide an important source of food and livelihood for coastal people. As a result, they adopt several techniques to catch fishes. Zag fishing is one of the native techniques to use for capture indigenous species and mostly responsible for declination of inland open water fishes. Zag fishing is an aggregating device for attracting fish, usually made with branches of bushy trees like hizole (Barringtonia acutangula), gamboling (Diospyros peregrina), babla (Acacia sp.), shewra (Sterbulus sp.), black berry (Syzygium cumini), jarul (Lagerstroemia speciosa), gab (Diospyros peregrine) and tamarind (Tamarindus indica) and are usually constructed when water begins to recede. The whole zag is supported by bamboo poles fixed around it to prevent downstream drifting of tree branches by water current. Water hyacinth (Eichhornia crassipes) and sometimes Helencha (Enhydra fluctuans) are used to cover the surface. Bamboo pole with 20 - 25 hand long and branches of bushy trees with 8 - 10 hand long are the essential materials for zag construction. Two types of zag are available in Chandpur of Meghna river estuary, which are small and large, comprises of 2 - 2.5 and 4 - 6 decimal of waterbed in the river respectively. 40 pcs bamboo pole with 200 pcs boughs and 80 - 90 pcs bamboo pole with 500 pcs bough and entire cost of 30,000 Tk. and 1,00,000 Tk. is required for construction of small and large zag respectively. In Chandpur, a number of fisher groups (8 - 10 fishers in a group) are available for setting up the zag after selecting the site up to fish harvesting finally. Zag fishing normally done by the rich and powerful (generally non-fishers), since zag construction is costly. General fishers mostly worked there as daily laborers. Initially the zag investor offers these groups for setting zag, all investment and operating cost bear by the investor while the outcomes from fishing divided in equal interval without deducting all cost. Usually, zag set up in the river from October to November and remain up until May. In these interim periods fishers can harvest fish 5 - 6 times from zag. First harvest done after two months followed by 1 month and 20 days interval for subsequent harvesting. For complete harvesting need 1 - 2 days and 4 - 5 days for small and large Zag respectively. The following fish species available in first 4 month are boal (Wallago attu), air (Sperata aor), rui (Labeo rohita), calta (Catla catla), chitol (Notopterus chitala), different types of chingri (fresh water prawn), gojar (Channa marulius), baim (Mastacembelus armatus), koral (Lates calcarifer) etc.
