    Description: Highlights: • Larval fish assemblages echo hydrographic seasons in the northern Persian Gulf. • Depth preferences separate the habitat use of dominant fish larvae family. • The Khark and Kharko marine protected area is a spawning centre in the region. Abstract: We examined the habitat use of fish larvae in the northern Persian Gulf from July 2006 to June 2007. Correspondence Analysis showed significant differences between hydrological seasons in habitat use and structure of larval fish assemblages, while no differences were found regarding abundance among coralline and non-coralline habitats. The observed configuration resulted in part from seasonal reproductive patterns of dominant fish influencing the ratio pelagic:demersal spawned larvae. The ratio increased along with temperature and chlorophyll-a concentration, which likely fostered the reproduction of pelagic spawner fish. The close covariation with temperature throughout hydrographic seasons suggests a leading role of temperature in the seasonal structure of larvae assemblages. Our results provide new insights on fish larval ecology in a traditionally sub-sampled and highly exposed zone to anthropogenic pollution, the northern Persian Gulf, and highlight the potential role of Khark and Kharko Islands in conservation and fishery management in the area.

    Description: The survey of fish larva in Iranian water has done from 1995 till 2007. The aims of this study were included of identification, abundance, diversity index and distribution of fish larva in Iranian coastal waters of the Persian Gulf. In all research, sampling was done by Bongo net in day time. Totally 119006 specimen was collected and identified in 54 fish larva family from 90 stations. Gobiidae, Engraulididae ، Leiognathidae، Sparidae، Sillaginidae، Clupeidae ,Cynoglossidae، Sciaenidae were the dominate families with higher abundance. 83342 specimen was collected from Khuzestan waters( higher than others )in 27 family,26797 specimen in 52 fish larva family in Bushehr waters. The result of GIS map was shown; Clupeidae with three subfamily distributed in all Iranian waters with more abundance in summer and autumn, Sillaginidae was percent in all study area with more abundance in Bushehr waters, Gobiidae was in estuary habitat with higher abundance in Khuzestan waters in warm period, Sparidae distributed in the Persian gulf in more month of year, Engraulididae was collected from area with more abundance from Hormozgan with two spawning peaks ;spring and autumn. Cynoglossidae with higher abundance from Khuzestan waters, Leiognathidae in Khuzestan waters was in warm period and in others site in all month. Sciaenidae was in Hormozgan more than others area. Mosa Creek-Estuary in Khuzestan with homogeny habitat was attractive the family related to the shore and muddy kind family, such as: Gobiidae, Leiognathidae whereas Bushehr waters with variety of habitat; Creek-Estuary, mangrove forest, rocky coral, coral path was attractive more family with different groups such as: lutjanidae ، Cepolidae ، Apogonidae، Lethrinidae and Atherinidae that some case only recorded from Bushehr in Persian gulf. Coastal waters of Bushehr province habitat was affected of sea waves and current therefore the abundance of family lower than Khuzestan waters except in some deeper stations. Finally there are different occasions influencing on fish larvae percent, abundance and distribution of them that are include: abiotic factors (temperature, salinity, depth and clarity), habitat, adult spawning behavior, morphologic characters of coastal area, In addition, from the type and geomorphologic structure of marine – coastal area, the difference between abundance and diversity of ichthyoplankton in two main coasts group as name wave dominant (open coasts) and tide dominant 9semi closed coasts) have harmony with together and are clear.

    Description: The coastal area of the water and drought graft area and the common area of the performance of two ecosystems with separate characteristics are one another. Coastal environment is a natural evolutionary system that includes the most complex and, at the same time, the richest ecosystems on the planet. This region is a transitional and highly vulnerable region and is endangered by the accumulation of pollutants due to the acceptance of drought and marine pollutants. Marine pollution and the effects of drought activities that are the result of socioeconomic development on the coastline and its catchments are one of the most important issues in most of the world, which directly affects coastal habitats. According to research conducted in Iran on identifying areas and sensitive resources, these areas and resources are divided into two distinct groups: 1) The group of biologically sensitive resources: includes mangrove forests, coral reefs, marine turtles, aquatic birds, marine plants and marine mammals. 2) The group of sensitive physical resources: includes the physical building of beaches in the sub-sections of mud, sand, rocky and hydrographic forms of shores in aquatic, estuarine, clay and small bay.

    Description: Caspian Sea with an area of 400 thousand square kilometers is the largest lake in the world. The Caspian Sea about 1200 km from north to south on the longest section and an average width of 320 km. Along the coastline around the Caspian Sea is about 6500 kilometers. Caspian Sea is about 78,000 cubic kilometers of water volume that is 44% of stocks of blue lakes around the world. Caspian Sea basin, which is composed of seven major basins of the main watershed from west to east are: juniper, Talsh- Anzali, large Sefidrood between Haraz Sefid and, Hraz- Gharehsou, Nagorno Sv- Gorgan and Atrak in the basin of Aras no limits to the beach. Aras sub-basin is located in the North West and Iran, the second largest sub-basin of the Caspian Sea. Talysh-Anzali on the Caspian Sea basin West and the seventh largest sub-basin of the Caspian Sea. White basin is located in the South East of the Caspian Sea and the extent of the sub-basin of the Caspian Sea. Haraz located in the south Caspian Sea basin and the ninth largest sub-basin of the Caspian Sea. Gorgan is located in the South East of the Caspian Sea basin and the fourth largest sub-basin of the Caspian Sea. In these areas, about 28 percent of the total fish production in the northern waters of aquatic allocated.

    Description: This project prepared and implemented during 2013-16 with emphasis on to provide the results of the fish larva projects (identification, abundance and distribution) in the Iranian waters of the Persian Gulf and Gulf of Oman which as well as had already been done by Iranian Fisheries Science Research Institute and affiliated research institutes and centers . Since each marine fish stocks management requires increased knowledge of the life cycle and be complete biological information, obviously implementation and increased field research is essential, on the other hand the results and the availability of data and information to operation and coordination with the scientific community at national and international levels is of particular importance. This is on condition that currently, due to the increasing trend researchers and students Aquatic Sciences and Fisheries, the availability of data resulting from studies and research projects and initiatives will be necessary. The site is currently only in view of identification and distribution of marine fish larva has been prepared in farsi with photo gallery, and english language development and preparation of the site for the international operation there. It is worth mentioning in the same areas and the same site adjacent seas of fish larvae has not been prepared and is not available. So this site can also be considered as reference area. This site is available for researchers, scientist and students as address: http://ifl.ifro.ir/

    Description: Although the most alga blooms usually provide positive impacts on marine ecosystems, but blooming of certain species of algae may also have negative impacts which evidence suggests that over the past few decades the frequency and duration of Harmful Algal Blooms (HABs) have been increasing both nationally and worldwide. Harmful algal blooms of Cochlodinium polykrikoides in the Persian Gulf and Oman Sea were first observed in 2008. In order to provide optimum growth and bloom forming, C. polykrikoides cells were sampled during the bloom conditions in the coastal waters of Bandar Abbass, Qeshm and Hourmoz Islands from March 2012 to June 2015. After sampling, the samples transferred to Persian Gulf and Oman Sea Ecological Research Institute phytoplankton Lab and adapted to filtered seawater. In Phycolab, they isolated and purified by positive phototropism characteristic of species to light. They were grown in modified media culture at different salinities (30, 32 and 35ppt), temperatures (20, 23, 26 and 28ºC) and intensities (35, 70 and 90 µmol m-2s-1). During this study 3 Dinoflagellates species were identified in Hormozgan Coastal waters. The first species was Noctiluca scintillans. This species was alive in F/4 media culture and under the 32ppt salinity, 25°C temperature, and an 11h light: 13h dark photoperiod regime only for 4 months. The second species was Protoperidinium quinquecorne and produced temporal blooms that could not be isolated under usual and modified media cultures. The last Dinoflagellates species that caused spreading blooms in Hormozgan Coastal waters and could be possible to isolate was Cochlodinium polykrikoides. The results clearly showed that the best media culture for growth of this species is A2 and the highest alga biomass was obtained following culture under the 32ppt salinity, 26°C temperature, and under an 11h light: 13h dark photoperiod regime at a light intensity of 90 µmol m-2s-1 provided by cool white fluorescent tubes. Maximum cell density of C. polykrikoides in a 5 liter Erlenmeyer for 12 days reached to 1.6 × 106 cell L−1 with 2-12 and occasionally to 16 cells chain. Based on the results from the present study, providing suitable media culture and physical condition, bloom forming of C. polykrikoides start from day 8 and will be continued until day 24.
