Port Okha– 361350 Dist : Jamnagar

Year of Establishment : 1969
Port Okha is a coastal town in Devbhumi Dwarka district of Gujarat state in India.Geographically it is location in between 220 28’0 N 690 4’0’ E. It is a peninsular place, situated on a narrow strip of land and surrounded by sea on three sides;Gulf of Kutch on north-east side and Arabian Sea on west side. It has a sandy beach on Arabian Sea coast.It has a sea port on the lee side. Historically it was the first port on west coast of India. Indian Navy, Indian Coastguard, Indian Customs, Gujarat marine police and Marine Police Academy have their operational command centre at Okha.
Historical Importance:
Port Okha is linked to Dwarka situated some 32 km south, which is one of the foremost “Chardhams” place and is one of the “Sapta Puri – Dwarawati” in the country. Bet Dwarka is an inhabited island at mouth of Gulf of Kutch situated 3 km (2 mi) off the coast of Okha. According to a legend, Vishnu killed the demon Shankhasura on this island therefore known as “Bet Shankhodhar”. The Bet Island and Okha are the large source of traditional, auspicious and sacred conch shells (Shankh) having ritual and religious importance.
Ecological Importance:
Because of Geographical location, 12 kilometers wide belt of Arabian Sea right from Okha, Dwarka, Salaya and Alang till Jodiya is full of mysterious sea life. The southern Gulf between Okha to Navlakhi of Devbhumi Dwarka and Jamnagar districts is declared as Marine National Park & Sanctuary (MNP&S). The revenue borders of Dwarka (Okha), Kalyanpur, Khambalia of Devbhumi Dwarka District mark the southern boundary of the marine protected area (MPA). The Marine Sanctuary when established in 1980 extended over an area of 270 sq. km., from Okha to Jodhya. The core area of 110 sq. km. was subsequently notified in 1982 as the Marine Park, comprising areas of 7,000 ha off Okha in the west and 4,000 ha off Jamnagar to the east.
The MNPS supports considerable species diversity. One study reported a total of 1,127 species of flora and fauna in the MPA (The Gulf of Kutch Marine National Park and Sanctuary: A Case Study by Nilanjana Biswas). These include molluscs (including auspicious, divine and sacred conch shells “Shankh” species Turbinella pyrum/Xancus pyrum- Varity Obsetusa), turtles and marine mammals: dolphins, whales etc. There are many species of fishes, commercially important prawn, crabs, sea snakes, sea horse, Sea anemones, Jelly Fishes, Starfishes, octopus, oysters, hard and soft corals, sponges, brown, green and red algae, etc. The floral property and richness of this place is next to none in the world.
Fisheries Research Station, J.A.U., Okha is strategically very important.
Demographic Profile of Okha:           
Port Okha is spread over in 5 Km2 area. According to 2011 census population is 62,052 and according to 18th Pasudhan counting report (courtesy: State Fisheries Dept. Okha) there are totally 210 houses of fisherman and their population (772 male and 726 female) is 1498 numbers. Out of which 394 are fully engaged in fishing activities. The main occupation is fishing and allied business here. There are 20 coastal villages near buy Okha and Dwarka among these Okha and Dwarka are two major and important marine fish landing centers of the State. In Okha totally 560 fishing boats (11 OBM and 549 IBM) are registered locally and engaged in fishing in which approximately 3887 fisherman are involved. The majority of fisherman population and boats are migratory from different coastal districts of Gujarat. The number of migratory boats varies from 2500 to 3000 (inclusive OBM and IBM) in which approximately 20000 to 25000 fisherman are engaged and directly employed in fishing activities. Tata Chemicals Ltd Mithapur, which is 10 km away towards Dwarka and visitors coming to Dwarka and Bet Dwarka for pilgrimage are another sources of livelihood here.
Fisheries Research Station located on the northern side of Okha Township on seashore is very crucial because of geographical location and the site is very rich in marine flora and fauna diversity.
Establishment History of Fisheries Research Station-Okha:
This research station initially established during 1969 by Ministry of Fisheries, Government of Gujarat, was named as “Marine Biological Research Station” (MBRS) basically. The main objective was to carry out survey of pelagic and demersal fishery resources along with effect of industrial effluents on the biota of the affected area and research.
On 29th February 1992 (afternoon) this MBRS was transferred and handed over to Gujarat Agricultural University, Sardar Krushi Nagar, Datiwada.  Than after, MBRS is named and recognized as “Fisheries Research Station” (FRS), which has started functioning from 1st March 1992. Most of the research and extension activities and infrastructure were transferred to GAU except mechanized boats and resource survey scheme.
As a result of bifurcation of Gujarat Agricultural University in to four different Agricultural Universities in 2004, this FRS is functioning under Junagadh Agricultural University, Junagadh.

  • Hatchery entrepreneurs are recommended to use 15 ppt salinity water for larval (zoea and mysis) rearing and 20 ppt salinity water for post larval (PL1 to PL20) rearing of Penaeus monodon (2015).
Shrimp Larvae Shrimp seed
  • Fish farmers of Saurashtra are recommended to feed gray mullet Mugil cephalus fry reared in seawater with 35% protein incorporated diet in first 45 days for obtaining higher growth and survival. (2014)
  • The fish farmers of Saurashtra are recommended that the fry of cultivable mullet species M. Cephalus are available abundantly, during February at Rupen and Harshad creeks ; M. Seheli during October-November at Khatumba and M. Parsia during August-September at Rupen and Harshad Creeks. (2013)
  • Thirteen species of rotifers are found in Okhamandal region. They are found in higher diversity as well as quantity in Surajkaradi pond and Gomati creek than seacoast areas in Okhamandal region in monsoon and post monsoon seasons. Rotifers are more abundant in less salinity. (2012)
  • Finfish/crustacean hatchery entrepreneurs are recommended to use 15 to 20 ppt salinity water at 25oC to achieve higher production of rotifer, Brachionus rotundiformis in 10 days. (2011)
  • It is recommended that carrageenana yielding marine alga Kappaphycus alvarezii can be grown profitably in Okha mandal region and fivefold growth can be achieved in 45 days from January onwards. (2011).
  • Among the available red seaweed (Rhodophyceae) species of Gulf of Kutch, maximum iodine content is found in Asperogopsis entestinalis (555 mg/100 gm DW) followed by Rhodomenis australis (151 mg/100 gm DW).(for Scientific community). (2011)

In order to maintain the population of M. seheli, Fishermen of Okha Mandal region should not catch the fish during this period”. (2005)
  • Recommendation is made for the farmers to use 3.5 % of liquide seaweed fertilizer made up of Sargassum Spp” gives good yield in groundnut variety GG-2.(2005)
  • To maintain the population of Mugil cephalus in natural water, the recommendation is made for the fishermen of Saurashtra region that the mesh size of gear (gill net) should be more than 93 mm as the fish obtain first maturity when the circumference of head was 189 mm. This will provide a chance of spawning high fecundity fish at least once in its life cycle. Moreover fishermen should not catch the fish at the time of breeding season (Dec-Jan.). (2002).
Future Outlook
  • Development of seed production of economically important marine shell fish and fin fish.
  • Development of marine aquarium fish breeding technology.
  • Culture techniques of economically important seaweed like Alginophytes, Agarophytes and Carrageenophytes.
  • Establishment of a centre for forecasting biomass (fish intensity) for marine fishermen in collaboration with related research institutes.
  • Cage culture of economically important marine fishes and crustacean like Lobsters, crabs etc in protected bays and lagoons.
  • Establishment of center of excellence-Advanced training center at Okha.
