Investigation on the species diversity of Pleuronectiformes order in the Iranian coastline water of Persian Gulf

In Iranian Coastline water of Persian Gulf we researched about flat fishes and revision their Scientitic names, Investigated diversity species (Pleuronectiformes) around three provinces such as khouzestan, Bushehr and Hormozgen. The aim focuse on introducting major family and Species Identification for this Purpose 1311 Specimens collected. Then 36 investigation Parameters includes 18 Morphometric, 11 meristic, 7 distribution has been measured in Excel. The descriptive statistic in spss software would be able us to graph dendrograms by Clustering methods, then Design a standerd table and comparised all the datas with it six major family has been found in Iranian Coasline which named: Soleidae, Bothidae Paralichtidae, Cynoglossidae, Psettodidae, Citharidae. Some of the scientific species names such as Pseudorombus arsius, P. annulatus, P. elevatus, P.malayanus, P. triocellatus from Bothidae family Join it to Paralichtidae family and Eurylossa orientalis change It's name from Soleidae family to Brachirus onentalis. Cynoglossus, bilineatus, C.Puncticepts, C.durbaensis, Clachneri, one of the most Important Point that viewed in our samples, founding a new species (C.Sp) Which we couldn't identify it with all the known keys, then sent it to international Scientific references for this porpose. (Family Cynoglossidae); Pseudorombus annulatus, P. elevatus P.arsius, P.malayanus, paralichtodes algoensis, Poecilopstei Javanicus (Family paralichthidae) Arnoglossus aspilos,A.arabicits, Engyprosopon grandisquama, L.pectoralis, Pseudorombus navalensis, Psettina brevirictis (family Bothidae); Psettodes erumei (Family Psettodidae); Citharoides macrolepis (Family Citharidae) in khouzestan Brachirus orientalis, Parachirus marmoratus, solea elongata, Zebrias synapturides (Family Soleidae) Cynoglossus bilineatus, C.puncticeps, C.arel, C.kopsii, C.

Khozestan has the maximus diversity speices (26 species) and the minimum is Hormozgan (15 Speices). 13 species of five family has never reported inpersian Gulf but we identify them in our studies for the first time. We abserved 29 Species of six family in our studies, comparision between are resualts with other researches shows that this use is the most compelet study in Iranian coastline water of Persian Gulf.

Examining the possibilty of multiplication and breeding of (Schizothorav [sic] zarudnyi) in order to restoration of regional aquatics reservations of Hamoon Lake and taking its advantag [sic] for aquaculture

Schizothorax zarudnvi, is an endemic fish of east country waters. (Triple lagoons of Hamoon and relevant water resources) that in the world it is reported in this resource specially. This fish named Hamoon mahi is one of the most economically valuable species in this region. Because of the recent years droughts, Hamoon logoon has been drive since 2000. Also, semi-wells (a semi natural resource) were affected drastically by recent drought years and their volume reduced to nearly one third of their real volume and resulted in changing at growth and reproduction physiology process in Schizothorax zanidnyi, brood stocks. Beginning of this project was done from October 2003. It's field studies begun (brood catching) since November 2001 by two methods including entangling gairs and at semi wells of Sistan that (Beach seine) had maximum rate of preparing qualified brood stocks. Broods transferred to Cyprinidea reproduction work shop of Zahak and after taking primary measures they stored in to the edaphic pools. Increasing the success safety factor (coefficient) for artificial reproduction of Sthizothorax zarudnyi , identifying the appropriate tune for Hormonal acceptance (physiological preparation of broods) is needed , so this important work was done regularly by histological studies and GSI measurements since November. Highest GSI rates of females (%80.51) and highest IV stage abundance of sexual maturity (%l 00) were observed an march. On the base of this date, Hormone therapy was done on broods on march. The used hormones are as follows Hypophysis. extraction, GnRHa and Anti Dopamin at the dozes of 3-6 ml, 20-30kg and 10-15 ml per kg body weight respectively and 2-3 times from 11-12-80 they were injected. Injected broods kept in to two circumstances, flow-through (rounded pool) and stagnant systems. In stagnant system 14 and 19 individuals of female and male (Schizothorax zauiulnri) broods, respectively injected in 11th, 15111, 19th, and 24th of march 1380. Non of the injected broods in 11 and 15 and 19th march (in stagnant Condition) answered to Hormone therapy. After final injection broods had general less activity and a few of them died. Mean temperature of brood pond waters (daily) which were injected. Fluctuated between 10-25-13. 63°c but injected broods on 24th march had different characteristics. They had pale color and had few fecundity. In this stage of injection they hadn't any successful vulation. After injection, Mean daily water temperature was 15, 88-17, 54°c. In Flowing system, 13-16 individual of males and females respectively were injected on 15th, 19th, 22th and 23th march. None of injected producers on 15th and 19th march with mean daily water temperature of 10, 25-12°c were prepared for spawning but injected producers on 22nd an 23th march with mean daily water temperature of 13.5-1 rc responded about 75-100 percent. (Schizothorax zarudnyi) brood stocks were prepared for spawning after 353-428 hours/day from final injection. Diameter of obtained eggs (before fertilization) was between 1.9-2.3 min and of fertilized eggs was 3.8mm. Fertilized eggs of (Schizothorax zarudnyi) were hatched after 6-7 days with mean water temperature of 17.08°c. Mean length of on one day larvae was 9.47 mm. Larvae was 9.47 mm. Larvae adsorbed the whole yolk sac after , 5-6 days at 17- 1°c and were prepared for releasing in to edaphic pools. Because of the lack of necessary and complementary facilities in the region , they had to release them in to veniros and growing them for 8 days. At the end of 18th day , 35000 larvae (at first) released into an edaphic pond with a volume of 150m2. After growing them for one moth , mean length and weight of new hatched larvae was 29.41 mm and 1.12►r , respectively. With respect to results of this investigation , artificial reproduction of (Schizothorax zarudnyi) Can be possible at 14-17°C and flowing water with Hormonal treatment. It -s breeding has increased development than other cultural specious in the region. Due to high economical value of this specious in Sistan and ti-s specialization east waters of Iran and having high resistance and proper growth There is a need of it's development and reproduction and culture in fish culture fanns (edaphic ponds• two-purpose pools) at the region and country.

Population diversity studies of pharaoh cuttlefish (Sepia pharaonis) in the Persian Gulf and the Gulf of Oman

The pharaoh Cuttlefish (Sepia Pharaonis) is the most abundant species in the persian gulf and oman sea. The stock patterns of this species was studied conserning biological, morphological and electrophoretical aspects. In addition to measuring the biological patterns; 21 quantitative and qualitative factors were measured or counted. There tissues namely muscle, eye and liver were also used for further polyacrylamide electrophoresis analysis (SDS-Page method). The densitograms of protein bands of each tissue were prepared by Gel-Scanner and also the amount of bands' areas were estimated. The results of LSD test showed that tentacle length (TL), Tentacle club length (TCL) and TCL were indicative factors which they showed significant difference between male TL and female specimen of Bushehr and Balouchestan regions. Regarding to length and weight frequencies data the results indicated that males are always bigger than females and also, the cuttlefishes of the gulf of oman are bigger than persian gulf's samples. There were found a significant sample correlation (95%) between different quantitative parameters and the most correlation (0.963) was found to be between TL and TCL; whereas the less correlation (0.384) was observed between GL and LA3. However the gill length factor illustrated the less correlation with the other factors. The results of Cluster analysis for both sexes showed that the cuttlefishes of both studied regions belongs to seperate stocks. The electrophoretic experiments of proteins showed that the protein bands of the sample tissue of muscle and eye from both sampling areas revealed significant differences; whereas the tissue of liver wasn't recognized as an indicative tissue for population studies. Taking into consideration the findings of the present study including: (1) difference in spawning season, (2) results of dendrograms, (3) observed Significant differences in one-way analysis of variance (ANOVA) for morphometric measurements, (4) differences in body length and weight, (5) ecological variations of the persian gulf and oman sea, (6) as well as the results of electrophoresis of proteins have indicatend that: "The Pharaoh cuttlefishes of Bushehr and Balouchestan waters belong to two seperate stocks. Also, it is believed that each region has propably two different populations and more studies are needed to approve this result.

A comparative ecological study on internationally important wetlands of Khoor-e-Kolahy and Tiab

Ecological study on Kolahy and 'flab estuaries were carried out during 1996-1997. Water and sediment sampling was done seasonally. In order to study the physical and chemical characteristic of the water, various animal fauna from different material niches including planktons and fish from water, benthousi from the sediment , and surface living animal such as Arthropod (Crabs) and Waterbirds were identified. I he result shoved, that water salinity of both estuaries was the same as the general salinity existing its the Persian Gulf water, and its variation is same IN those waters Minimum water salinity in both estuaries are seen during Bahairdan or early winter mooth(Jaa.), which is about 31ppt and Maximum is during .rirldlun.) or summer mouth at about 19 ppt. Dissolved otygen and pH are slime as the general Persian Gulf waters., Dissolve Oxygen being directly associated to temperature and its fluctuation is between 7- Sing/I and pH between 7.5-LS. The animals of both estuaries are almost similar having a sal factory species diversity . The birds of the region are often seasonal migrants , the maximum population of which occurs in winter season and the minimum during summer month. Nam coverage is richer in Tiab than Kolahy estuary, where in Kolahy a signal Mangrove tree is in exigence. 'Ile total coverage of Mangrove forest in Tiab is estimated about -29 hec.Both estuaries are included with in the international Ramsar Convention sites in 1971. Due to national importance of these estuaries inproviding refugee for various birds species and also hinting grounds and access traffic for local fishing vehicles, Actiog as an important access for various inhabitancy living with these area of the Persian Gulf. Due to importance or prawn aquacultur for the economical well being of local inhabitance, these areas provide a suitable grandees for prawn production. I-test statistics show, there are no significant difference among various invertebrate and vertebrate animals. In over all out look 21) phytoplankton genera, 21) zeoplankton genera 17 miafauna and 32 roaerofauna genera , 11 different species Carcineacearions and 119 species of walerbirds were identified with in the Tiab and Kolahy estuariesregioos. The X statistic show that the animal density is directly associated to season. Where density of miofauna and maerofauna in both estuaries are in maiticrourn during summer and the minimums existing during the winter season. In addition the bentic invertebrate population density in closlly association to birds population density since , the later, feeds on the former animals. Where the increasing in bird population density during the winter season, the bentic invertebrate animal population density decreases. The over all trend of animal population density in winter tend to increased towards the summer seasons, which this is due to climatic conditions of the region. The bird population on the contrary to other animals of both estuaries tend to increase from summer towards the winter seasons and which this bird population density is in maximum in winter with in the region.
