    A Survey on environmental effects of shrimp pond culture effluents in Gwatar area (Sistan & Blouchestan) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Present project was conducted in shrimp farm located in east of Chabahar in Sistan and Balouchestan province.Twentieth sampling stations at three locations (i.e. 2 stations in supply channel,13 stations in drainage channel and 5 stations in Gwatar Gulf) were selected to determine physical and chemical factors such as; temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, ammonia, phosphate and biological parameters for example Chlorophyll a, phytoplankton and zooplankton. Sampling was conducted once a month from March 2003 until January 2004. The results revealed different bioenvironmental area in the three locations (i.e. supply channel, drainage channel and Gwatar Gulf) over the study period. Concentration of salinity ,pH , nitatr ,nitrite ,ammonia and chlorophyll a in drainage channel were more than supply channel and Gawtar Gulf. While concentation dissolved oxygen and phosphate were in drainage channel less than Gawtar Gulf.Also, sediment with small grain size (clay and silt) caused uptake phosphate and amount phosphate decreased in drainage channel. Considering with lack of environment standards in Iran shrimp effluent, data compared with others countries standard. Results showed that with considerable farm area , value of temperature , salinity , dissolved oxygen and pH were in permit range in Gwatar Gulf while concentation nitrate, phosphate and chlorophyll a were sometimes more than permit range that could cause plankton bloom.Also, Gwatar Gulf were influence monsoon. Nitate , phosphate , chlorophyll a and phytoplankton increased in gwatar Gulf.Regards with that postmonsoon was simultaneus with shrimp harvest.Therefore, increase some parameters could be caused from shrimp effluent or postmonsoon. Thirty four phytoplankton genus were identified including diatoma, dinoflagellate , cyanophyta and chlorophyta. In each area maxiumum percentage of phytoplankton were belonged to diatoma( 63%) in supply channel , cyanophyta(51.7%) in drainage channel and dinoflagellate (94.5% ) in Gwatar Gulf.Amount and range chemical and physical factors and plankton composition were different in drainage channel , supply channel and Gwatar Gulf. Cyanophyta could grow more in drainage channel.Percentage of aboundance and diversity of phytoplankton changed in 2002 inrelation to years ago( before shrimp culture , 2000 year and 2001 year) specially in Gwatar Gulf.Mainly percentage of zooplankton were copepoda and thintinida respectively.Diversity zooplankton decreased ratio to years ago. In drainage channel , abundance total of phytoplankton and zooplankton were more than Gwatar Gulf and supply channel.

    Planning and establishment of the laboratory information database system for Iranian fisheries research organization (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Due to lack of access to comprehensive and up-to-date information regarding equipment, personnel, laboratory services tariffs and chemicals in the laboratories of Iran Fisheries Research Institute and felt the necessity of having this information for optimal management of the laboratories, it was decided with regard to all information needs in this area and using previous experiences in this regard as well as the experiences of other institutions and related organizations at the national (and even international) level, the system would be designed. The main purpose of implementing this plan was to establish and implement a software system based on web technology to create a comprehensive database of the Fisheries Research Institute's laboratories, so that in addition to organizing information, using periodic reports on various related areas a more appropriate monitoring and management system could be applied. Fortunately, after the design and implementation stages, the system in early January 2011 was fully applicable. The main parts of this system include portal; database; advanced data entry, search and reporting capabilities; direct tests order system and discussion forums.

    Assessment of ecology shrimp culture ponds in Gwatar Determi (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: At the present research four farms, supply and drainage channels were assessed in phase Cl shrimp culture sight or Gwatr from June It) November For this purpose, physical and chemical factors were measured include temperature salinity , demand oxygen and pH twice just one day and nitrate nitrite ammonia silicate phosphate , turbidity and total suspended solid once just one day in a week sampling was carried out as fallow biometric or shrimps every week plankton twice a month , macrobentoz , grain size and TOM monthly. The results obtained from biometrics factors showed that final weight were (12.03 18.65 gr) as well as the survival rate was (26.6 90.35) on the farms. The maximum final product and minimum was 2696 772 kg/h respectively. Based on amount of stoking survival and the factors of management, the result of physical and chemical factors indicated that salinity total suspended solid and turbidity were not the optimum range. Preserving this three factors have the paramount importance in our area. One way analys of variance chemical and physical' factors have showed significant difference between the days of culture and also salinity, demand oxygen and temperature showed 'significant difference between morning and afternoon (pSO.05). In this research 84 general phytoplankton were identified that diatom was dominant 9 Groups zooplankton were identified that their major percentage of groups were copepod and rotifers respectively. Benthos density was very poor . Abundance and diversity of benthic was very low in ponds and dominant group of macrobenthose was Mysidae. Usually the grain sizes of the bottom were sandy - loom * TOM of bottom was increased and acidity was decreased after harvesting compared to before irrigation. The factors of management inducing perpetration pond , quality 01' post laree , stocking , exchange water airing and feed of Shrimp of' ponds compared and the results shows that farm 2 was the best one .
