Introduction : 
Aquaculture contributes almost 50% of the world’s food fish. Indian seafood export cross US$ 7 billion during 2017-18, which include frozen shrimp and fish with 11,34,948 MT and 5.77 billion dollar. The vannamei shrimp exported during 2017-18 was around 4,02,374 MT along with a farm-gate value of over US$ 4,848.19 million. Considering the projected population growth over the next two decades, at least an additional 43 million tonnes of aquatic food will be required by 2030 to maintain the current per capita consumption. Asia produces over 90% of the total aquaculture production of the world and it is projected that most of the aquaculture growth will be in developing countries. India is amongst the top three producers of rice, wheat, liquid milk, poultry products, fruits, vegetables, coconut, tea, spices, marine and fresh water products including fish and shrimp. Gujarat is in thefore front of marine fish production in the country.
Gujarat is endowed with a splendid array of marine and inland aquatic resources. The state has a long coastline extending to 1600 km, a continental shelf are of 0.16x106 km2, Exclusive Economic zone of 0.12x106 km2, rivers and tributaries extending to 3865 km, reservoirs with 0.28x106 ha., ponds and tanks of 0.07x106 ha and brackishwater area of 0.37x106 ha. Gujarat occupies 32% of the continental shelf area and 10% of the total EEZ of India. Fishing industry which has grown substantially in the last four decades with the continuous intensification of a fishing effort, contributes significantly to, economic, social and nutritional wellbeing of the people of Gujarat.
The marine fish production in Gujarat is more than 7 lakhs M. tones, but fresh water fish production is very low & it remained between 9-11 % of total fish production of the state. Its poor growth is mainly due to the fact that most of the existing natural water resources are not utilized properly for fish cultivation. Pond based freshwater aquaculture technology has been perfected in the country, but it has not been reached to the grass root level due to poor extension system.
The new era of shrimp farming begin in 2010 with introduction of Pacific white shrimp Litopenaeus vannamei, the SPF and High health status was the lead attraction with high production capacity. Shrimp farming industry hugely benefited after the introduction of vannamei species and within few years the national production went up manifold increase, from 80000ton to 380000ton in 2016. Presently Gujarat is producing 45000tons of high quality shrimp from 6500hectare @ 7000kg/hectare.
Transfer of technology to the level of farmer is greatly felt in Gujarat. Salinity ingress in coastal fellow land is increasing at alarming rates in the country especially in semi-arid and arid climates of the northern and western states including Gujarat. Due to this agricultural production in salt affected soils is drastically reduced. In India research on aquaculture aspects in Inland Saline water regions was started with a survey of saline water resources by the Central Institute of Capture Fisheries Research Institute of ICAR. As a result it could be possible to successfully culture several brackish water fish species in Inland saline water. However much more efforts are needed to have its contribution in the socio-economic development of affected regions. In Gujarat majority of people are not aware of fish farming and its prospects, hence it is necessary to create awareness among the people of Gujarat to adopt fish farming as a profession. In order to address the issue of utilization of saline ground water in salt affected soil by aqua-based production system modules in coastal area of Saurashtra for development of suitable technology and to transfer the technologies by imparting training to the end users, this project is envisaged.   In order to impart training to the farmers for adopting fish farming and to utilize available resources in a scientific manner and for generating employment opportunities in rural youths of coastal districts, a systematic full-fledged advanced training centre can play a vital role in enhancement of inland fish production.

IMPACT OF NICOL and MALAN BANDHARA/RESERVOIR ON FARM
Government of Gujarat, Salinity Control Board, Gandhinagar  in the year 2001-2002 constructed Nicol Bandhara  (Reservoir constructed by restricting water flow of river to sea) and the reservoir water can be utilized for freshwater aqua farming. In the same way in year 2009-10, Government of Gujarat, Salinity Control Board, Gandhinagar constructed Malan Bandhara (Reservoir constructed by restricting water flow of river to sea).
This reservoir is providing livelihood to numbers of fisherfolk, both husband and wife with the help of small canoes/ boat, fishing activities is taken up, this capture fish stock is locally consumed as well as marketed to local market, even transported to Surat and Ahmedabad area.
 For research point of view, this freshwater source can be helpful for standardizing the local finfishes culture technique as well as freshwater pearl culture can be taken up. This water is rich in nutrient and hence big mass of harvesting is taken up every year.  Freshwater research on IMC seed production is one of the best opportunity, for supplying IMC seeds all along Saurashtra belt.
Achievements:
Fisheries Research and Training Centre – (B.H.-12016):
Recommendation to fish farmers:
1. Fish Farmers are recommended to incorporate three Probiotics Lactobacillus subtilis (15x107 cfu/g) +Bacillus subtilis (10x107 cfu/g) +Sacromycescerevisiae (10x107 cfu/g) in the ratio of 4:3:4@ 3% in fish feed to obtain higher growth, nutritive value and survival rate of Labeorohita in rearing pond.
2.  Shrimp farmers who is willing to culture Fenneropenaeus merguiensis(Banana shrimp) shrimp in their pond are recommended to adopt pond bottom, having combination of sea sand + mud (50:50) with approx. 6 inch sediment thickness, to obtain better growth and survival rate.
3.  The brackish water shrimp growing farmers are recommended to stockLittopenaeus vannamei shrimp seeds @ 25 pc/m2 to obtain better survival, growthand economical return.
Scientific recommendation:
Shrimp species availability:
The Fisheries scientists are suggested that at Mahuva area cultivable shrimp seeds are available in scanty catch composition of Metapenaeuskutchensis followed by Fenneropenaeus merguiensis, F. indicus and P. monodon with peak during month of Sept. to January whereas at Jafrabad scanty catch composition of F. merguiensis followed by Metapenaeuskutchensis, F. indicus&P. monodon during April to May are available.
