  1. The AGB is a function of salinity and hence we can jointly work to establish a data bank estuary wise – with salinity

  2. The mangrove ecosystem of Indian Sundarbans acts as the breeding ground and nursery of several categories of fishes in the lower Gangetic delta. This paper is an attempt to capture the threats operating on fishery resources in the western sector of Indian Sundarbans (around the Hooghly estuary) through computation of Combined Threat Scale (CTS) based on the product of Threat Ranking (TR) and percentage of voting of the respondents to achieve the total threat score.

  3. The ecosystem services of estuaries are wide and intricately related to the livelihood of the surrounding population. These services include production of fishes, molluscs, crabs for commercial/economic gain of the local people, navigational channel for transportation of local people, fishing vessels and trawlers, passenger vessels, cargo ship etc., regulatory services like flood control, bioremediation, tidal action etc.
    The flow of water along the estuaries is hindered by thousands of nets that are laid along the stretch for trapping seeds of tiger prawn (Penaeus monodon). This profession is extremely detrimental to the ecosystem services (Roy Chowdhury and Mitra, 2017). The Government of West Bengal has already banned the wild fry collection. Lack of alternative livelihoods for prawn seed collectors is one of the principle constraints on implementing any policies, laws and/or regulations geared towards the development of a sustainable resources use strategy as well as conservation effort for the wise use of the marine, coastal and estuarine resources (Ahmed et al., 2012). For this, the Government placed the enforcement of the fry collection ban into abeyance (in many developing countries) pending further review of how the resource and biodiversity could be conserved at the same time as protecting the livelihoods of 300,000 fry collectors (Williams, 2002).

  4. Tiger prawn seed collection is a common profession, which is detrimental to the socio-economic and biodiversity profiles of Indian Sundarbans. Apart from destruction of finfish and shell fish juveniles (Roy Chowdhury and Mitra, 2017), the practice of dragging the nets along the shore uproots the mangrove seedlings. These seedlings not only control soil erosion, but also act as a major sink of carbon dioxide (Agarwal et al., 2016, Mitra et al., 2016a; Mitra et al., 2016b; Pal et al., 2016; Zaman et al., 2016; Mitra et al., 2017). This practice is therefore a serious threat to ecosystem services of Sundarban estuaries (Mitra and Zaman, 2014; Mitra and Zaman, 2015; Mitra and Zaman, 2016). Because of recession in traditional livelihood like agriculture (due to expansion of shrimp culture activities) and lack of alternative livelihood schemes at commercial scale, people of Sundarbans are accelerating their dependency on prawn seed collection. Considering the negative impact of this profession it is of utmost importance to procure prawn seeds from hatcheries (available in plenty from the adjacent states like Odisha and Andhra Pradesh), develop seed bank and provide alternative livelihoods through ICZM (Integrated Coastal Zone Management) programme as a separate section for this mangrove dominated World Heritage Site.
