Fisheries Research Station

Junagadh Agricultural University

Port Okha– 361350 Dist : Jamnagar

Year of Establishment : 1969
Introduction:
Port Okha is a peninsular place, surrounded by Gulf of Kutch from north-east side and Arabian Sea from west. The place is linked to Dwarka, a holy pilgrimage place situated south of Okha about 32 kms through road. Major population comprise of fishermen community engaged with active fishing in the Gulf of Kutch and Arabian Sea. About 2000 mechanized boats are engaged in active fishing during season from August to May. Fisheries Research Station is situated on the northern side of Okha township. Geological location is in between Lat' 220 68'N - Long 690 05’ E.
The research station was established in the year 1969, under state Fisheries department.
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. The station was meant for carrying out Marine Biological Research and hence it was known as MBRS. The aspect under research was collection of natural brooders of Penaeus merguiensis and P. monodon. Ready spawners were collected through departmental vessels and seeds were produced for its culture as well as for sea ranching. There was separate wing for value added product preparation from trash fishes. Most of the research and extension activities were transferred to the then GAU except mechanized boats and resource survey scheme. At present this research station is under roof of Junagadh Agricultural University.

Sea ranching of green turtle (Chelonia mydas) and Olive ridley turtle (Lepidochelys olivacea) for natural population recruitment. 600 new born babies have been sea ranched in between 1995-2000 for protecting and preserving the endangered species of sea turtles (Schedule I species).
  • Sea ranching of green turtle (Chelonia mydas) and Olive ridley turtle (Lepidochelys olivacea) for natural population recruitment. 600 new born babies have been sea ranched in between 1995-2000 for protecting and preserving the endangered species of sea turtles (Schedule I species).
  • Successful mass scale Kappaphycus cultivation at Okha; 5-7 fold growth were achieved in 45 days.
List of Recommendations / Scientific Information :
  • 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)
Rotifer
  • 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)
  • It is recommended to salt farmers and aquaculturist of coastal Saurashtra region to use 160 ppt salinity of sea water as a rearing medium for Artemia (Artemia fransiscana) to obtain higher cysts production.(2010)
Artemia Cysts
  • It is recommended to incorporate probiotics (Lactobacillus acidophilus) @ 20% in feed during culture of shrimp for higher production (2007)
  • It is recommend that the 20% Prosopis juliflora pod powder, incorporated along with fish meal-10%, soyabean meal-40%, wheat Bran-15% and cotton seed oil cake-15% in pellated feed is better for higher production as well as survival rate in mullet fish culture. (2007)
  • It is recommended to scientific community and fishermen that gravid female (Length 375mm & above) and male (Length 341mm & above) of Mugil seheli are available in coastal sea water of Okha mandal region, during its major breeding season late August to September and minor breeding season February. 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 fishes like Mugil cephalous, Lates calcarifer (sea bass), Chanos chanos (milk fish) etc.
  • 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.
  • Mass scale cage culture of M. cephalus, Lates calcarifer, Panulinus polyphagus (Lobsters) in protected bays and lagoons.
  • Establishment of center of excellence (Advanced training center at Okha for which proposals are under preparation for submission to ICAR.
