Report of the project on “Mapping of coastal resources and identifying suitable areas for expanding integrated multi trophic aquaculture (IMTA) in Maharashtra”
Background
Sustainable aquaculture is to develop ecologically efficient, environmentally friendly and socially acceptable farming practices to satisfy and maintain the quality land and water resources for the future generation. The State of Maharashtra ha vast stretches of estuaries, creeks and mangrove swamps which offers great potential for aquaculture, particularly for mud crab farming.In view of the natural resources and market potential for aquatic animals, the Department of forests, Government of Maharashtra aimed to promote aquaculture farming in the state of Maharashtra, through a novel approach which aims at providing livelihood support to the local communities utilizing the mangrove wetlands; thereby the local communities also shoulder the responsibility of conservation of mangroves. A preliminary surve was conducted to identify the suitable creeks using water quality characteristics and also GIS environment. Further evaluation will be done based on various physical and environmental criteria including topography, soil types, land-use system, vegetation, water quality, water availability, salinity, risk of flooding, infrastructure, seed resources and availability, market and support services.
Added to this, carrying capacity of many source waters has been exceeded or likely to exceed due to over development of shrimp farming and low tidal amplitude in certain areas. While identifying the land suitability, carrying capacity of water bodies has to be estimated based on the maximum nutrients loading which can be assimilated by the water body without exceeding the permissible levels of water quality and flushing /dilution rates, and supportive capacity of ecosystem. The unplanned and uncontrolled expansion of shrimp aquaculture had led to exceeding the carrying capacity of the source water bodies, which resulted in negative impacts of poor productivity and occurrence of diseases in some regions. Water quality and soil characteristics were never associated with site selection process, led to environmental issues and poor productivity. Considering the present land use, extent of utilization of resources, carrying capacity of the source water bodies and site specific water quality parameters, there is a need to identify the suitable sites or zones for aquaculture adhering to environmental regulations and unfertile and low lying areas for the alternative livelihood development. In addition, Indian aquaculture is dominated by monoculture with few species and may not be sustainable in long run. We need to diversify and there should be a paradigmatic shift from monoculture to polyculture system. IMTA can be an alternative to monoculture with three or more species at different trophic levels with compensating feed practices, i.e waste from one species act as feed for others. To carry out the IMTA, suitable waterbodies and areas needs to be identified before planning. Specific objectives of the proposed study ● To conduct the preliminary survey and identify the suitable areas for IMTA in Palghar, Raigad, Ratnagiri, Sindhudurg and Thane districts of Maharashtra ● To assess land use pattern from satellite data and GIS, carrying capacity, water availability and water quality characteristics in the major source water bodies to select the suitable areas for IMTA through GIS based MCDSS Work component Phase I. ● Phase I component. Preliminary survey and Identification of suitable areas for IMTA in Palghar, Raigad, Ratnagiri in Sindhudurg and Thane districts of Maharashtra and coastal resources assessment Work done: Preliminary survey was carried out in the coastal districts of Maharashtra to assess their suitability for aquaculture. The physicochemical and biological parameters were analyzed from five district (Palghar, Thane, Raigad, Ratnagiri and Sindhudurg) creeks and river waters of Maharashtra state.

Present study reveals that Ammonia and chlorophyll-a were exhibiting high concentration and depth was (1.5 m) during low tide in Pantambi river of Palghar district it could be due to the highly innfluence of Industrial effluents and domestic waste, it may lead to microbial oxidation of organic matter, which indicates the deteriorating water quality for cage aquaculture. In Ghivali creek depth (1.5m) was observed very less and not sufficient for developing cage culture. Chandigone -Dahanu River showed high turbidity, during low tide and water depth was less during low tide. The Dahanu river mainnly polluted by the domestic effluent, released from Dahanu Municipal Corporation and Thermal Power Plant. The Vaitarna River lowest level of water, high turbidity and water high flow were observed during low tide respectively.

In Amba River, low DO (2.69 mg/l) level was observed and high turbidity (90 NTU) was observed during the low tide period. The preliminary survey indicated the effect of industrial and dredging activities nearby selected station of Shirkichal village. In Kundalika 2 m creek depth and high turbidity (58 NTU) was observed during the low tide period. The river has a water only in high tide period. The high water turbidity (81 NTU) was observed and low water availability during low tide period in Rajpuri Creek. The same conditions prevailed in Savitri River water also.

The results given were based on the findings of the one time preliminary survey. The survey and assessment will be carried out for all other seasons along with the mapping of activities associated with the creek . Further evaluation will be done based on various physical and environmental criteria including topography, soil types, land-use system, vegetation, water quality, water availability, salinity, risk of flooding, infrastructure, seed resources and availability, market and support services.
II. Survey of coastal resources – second season February
Assessment of coastal resources and survey was carried out in the coastal districts of Maharashtra to assess seasonal variation of water quality in the month of February 2018. Water quality and depth were measured for the coastal waterbodies associated with the villages. The satellite data interpretation ground truth verification also initiated.
