Short communication: Morphometric and meristic comparison between two similar species of Luciobarbus barbulus (Heckel, 1847) and Luciobarbus pectoralis (Heckel, 1843)

The two species, Luciobarbus barbulus (Heckel, 1847) and Luciobarbus pectoralis (Heckel, 1843) are similar to each other and some researchers get confused and mistake one for the other. During a one year seasonal sampling, 79 specimens were collected from the main rivers of west and southwest of Iran in the Tigris River basin using electrofishing as the main method for sampling. Samples were fixed in 10% formalin and transferred to the laboratory, Then 24 morphometric and meristic parameters as well as 11 ratios of the major parameters between the two species were studied. According to the results of this study in addition to similarities there are ten differences between them, with the most important ones being the shape of the head and lips, number of gill rakers and number of pectoral fin branched rays

Introduction of metallic pollutant (Fi , Ni) reducing bacteria in Musa Bay

In order to isolate bacterial strains resistant to iron and nickel, deposit samples were collected from five stations in Musa Bay and cultured on BHI agar medium containing 1000 ppm of iron and 50 ppm of nickel. Endurance threshold of strains isolated to different concentrations of iron (1000- 15000 ppm) and nickel (100- 25000 ppm) in BHI broth medium were evaluated, the most resistant strains were selected and MIC and MBC were determined. Results of the current study demonstrated that among 16 and 12 resistant strains to nickel and iron, two selected strains (Bacillus subtilis and Micrococcus sp. ) as the most resistant strains had MIC and MBC (29700 and 29800 ppm) and (26300 and 26500 ppm ), respectively, Iron’s MIC was not assessed. Results of atomic absorption analysis demonstrated that the highest amount of nickel reduction in a medium with concentration of 194 ppm and 71 ppm were 16.7% and 63% after 72 hours by selected strain of Bacillus subtilis respectively, and in a medium containing 158 ppm iron, after 50 hours 8.4% by selected strain 7, while dead biomass of strain 16 reduced nickel to the amount of 40.6% and it reduced 21% and 4% of iron in solutions with 46 ppm and 792 ppm of iron. Results of molecular analysis demonstrated that strain 16 was Bacillus subtilis. In addition, Bacillus subtilis being isolated in this study with ability of nickel and iron removal is an appropriate candidate to be used in aquatic environments

Reproduction and maturity of false trevally (Lactarius lactarius) in coastal waters of the Oman Sea

In order to determine the reproduction period, the peak time of spawning, length of maturity and mesh standard size for False Trevally (Lactarius lactarius), we conducted a study from November 2007 to October 2008 in coastal waters of the Oman Sea. A total of 702 False Trevally specimens were collected randomly from the catch composition of gillnets and Ferdows-3 stem trawler. Mean total length and total weight were estimated at 22.7 plus or minus 2.13cm and 142.2 plus or minus 41.64g for females and 20.4c 1.89cm and 103.14c 29.07g for males respectively. Male to female sex ratio was 0.37:1 and females were more abundant than males in all months except June and August. Males had smaller sizes than females and the females outnumbered the mails up to the total length 25.5cm. The maximum of GS delta was estimated at 3.69 for females in June and 0.89 for males in July. The trend of GS delta and the frequency of maturity stages showed that reproduction period was from February to September with a spawning peak in August. Absolute fecundity was calculated at 102032 ova and relative fecundity was estimated at 4491.9 ova and 780.7 ova to total length and total weight respectively. Lm sub(50%) (length of maturity) and standard mesh size was calculated at 24.4cm and 3.9cm, respectively

Ichthyotoxism in Capoeta capoeta gracilis (Keyserling, 1861) from west of Urmia (Marmisho Lake), Iran

Fish egg poisoning is a public health hazard although usually the incident rate, mortality and fish species involved are not well reported (Halstead,1970). Four species of Cyprinidae in Iran have been suggested as ichthyotoxic by Coad (1979) .namely Abramis brama. Cyprinus carpio .Schizothorax zarudnyi and Tinca tinca and it was thought that other species may be discovered subsequently.Najafpour and Coad (2002) reported ichthyotoxin in the cyprinid Barbus luteus from Iran ,and the study records another species. The Cyprinid fish Capoeta capoeta known as Siah mahi or gara balig in Iran

Identification species of Acanthopagrus (Family: Sparidae) and stock identification of dominant species in the Persian Gulf and Oman Sea using geometric morphometry and otolith

In this study, the identification of the Acanthopagrus species Sparidae family by morphometric characters & meristic counts and the stock separation of Arabian yellowfin Seabream Acanthopagrus arabicus as the dominant species was determined through geometric morphometric and otolith shape in the west and east part of the Hormuz Strait. Samples were collected in five different areas including Khuzestan, Bushehr and Hormuzgan Waters as the west of Hormuz Strait, and Jask, Sirik and Sistan & Baluchistan Waters as the east of Hormuz Strait from June 2014 to May 2016. A. arabicus, A. berda and A.bifasciatus were identified in the northern part of the Persian Gulf & Oman Sea, the first one was identified as a dominant species of this genus. Evaluation of morphometric characters and meristic counts indicated that individuals of A. arabicus in west and east of Strait of Hormuz were significantly different from each other which showed high phenotype diversity of this species (p<0.05) and 85.3% of the individuals were categorized precisely in the correct classification which indicated as a key identification method in the region. From the meristic counts, the number of scales on the lateral line, on the chin and scales from the fifth and ninth spine of dorsal fin to the lateral line were the factors of separation in the west and east of the Strait of Hormuz. Body shape analysis was showed the most variations on the head and top of the body and significant differences of body shape was proved between west and east of Strait of Hormuz. Landmark positions in the samples of the west Strait of Hormuz were indicated the decrease of body depth, increase of head length, leaning of base and pectoral and ventral fin to upper part of the body, meanwhile it was contrary in the samples of the east. CVA correlation analysis showed a significant difference in body shape in the west and east of the Strait of Hormuz (P <0.0001). The otolith shape indices showed a significant difference in the west and east of the Strait of Hormuz and the results of the DFA analysis confirmed the accuracy of the classification of the species in the main region by 53.8 percent and the otolith shape in the west of the Hormuz Strait was more circular and had an equal growth in the length and width, while in the eastern part of the Strait of Hormuz they had more growth and aspect ratio, ellipticity and form factor of the area were approved. The results of the otolith Fourier Shape Analysis showed that six components out of the 77 main components were expressed 90 percent of the cumulative strength and difference, and the most changes were observed in the dorsal and ventral part of the otoliths of the Arabian yellowfin Seabream, and 70.4% of individuals of this species were correctly classified in the west and east of the Strait of Hormuz. The results of this survey confirmed two separate stocks in the west and east of Strait of Hormuz

Length-based fishery status and population dynamics of Spiral Babylon, Babylonia spirata, Linnaeus, 1758, stock in the northern waters of the Oman Sea, Sistan and Baluchestan Province of Iran

In the present study, the population characteristics of Spiral Babylon, Babylonia spirata, were evaluated by sampling at four sites in the northern Oman Sea, Iran, including Pozm, Konark, Beries, Pasabandar from March 2021 to March 2022. A total of 2779 Babylonian snail specimens (1489 males, and 1290 females) were measured and about ten percent of the specimens were described. The mean length and weight of males and females were 36±5, and 32±5 mm and 14±6, 10±4 g, respectively. Growth and mortality indices for females and males including infinite length (L? = 68 and 76 mm), growth coefficient (K = 0.54 and 0.3 (yr-1)), natural mortality (M= 0.7 and 0.4 (yr-1)), fishing mortality (F = 2.30 and 1.79 (yr-1)), total mortality (Z = 3 and 2.19 (yr-1)) and exploitation coefficient (E = 0.77 and 0.82 (yr-1)) were estimated. Based on the LBSPR assessment model, estimated to be about 0.3, and a ratio of Pmega&lt;0.1, Lmean/Lopt &lt;1 and Lmean /LF=M&lt;1 show considered undesirable. The present study showed that the Spiral Babylon stock has reached 'overfished' status

O Paranismo atualizado: a democracia cristã e o planejamento no primeiro governo Ney Braga

Este artigo é um resumo da tese que trata do primeiro governo Ney Braga (1961 a 1965), reconhecido como uma experiência inovadora, que, ancorado no programa do Partido Democrata Cristão e no ideário da Democracia Cristã, editou o Plano Paranaense de Desenvolvimento, elaborado pela Sagmacs, sob a direção do Pe. Lebret.  A tese procura mostrar que as ações desse governo estavam mais próximas da ideologia desenvolvimentista, adotando postulados típicos da abordagem centro-periferia de corte cepalino, do que das diretrizes que pudessem emanar da Democracia Cristã. Constata, assim, uma continuidade dos modelos desenvolvimentistas dos governos estaduais e da União que o antecederam, tratando-se, portanto, de um tipo recorrente nos governos. Nesse processo, aponta que os intelectuais que fizeram referência a essa experiência estavam reeditando uma visão muito particular do Paraná conhecida como "Paranismo", ou seja, um sistema de valores assentados na ideia do Paraná como um Brasil diferente. A partir daí o estudo pode afirmar que esse paranismo é uma modalidade de ideologia, voltada para a integração de um território dividido pelo processo de ocupação. As contribuições teóricas de Mannheim foram fundamentais para o desenvolvimento deste estudo, em especial no que se refere à ideologia e ao papel de uma camada de intelectuais, a intelligentzia, no planejamento. Igual relevância teve o estudo de Miriam Limoeiro sobre o desenvolvimentismo e a ideologia desenvolvimentista, presentes nos discursos de Juscelino Kubitschek e Jânio Quadros. Muito importante foram as investigações de Maria Helena Oliva Augusto, sobre a Codepar, e de Francisco Borja de Magalhães, sobre o modelo paranaense de planejamento, obras precursoras na análise e interpretação do planejamento no Estado do Paraná

Physical and chemical factors determination of Mohammadiye Channel water for aquaculture purposes

In this survey the Physical and Chemical factors were studied in mohammadiye channel extending Eslamshahr, Robat karim and Shahriar cities of Tehran Province during the 2011 in agriculture period (May, June, July, August, September, October) Sampling were done from 5 different stations. The measured factors were temperature,DO, Cl,HCO3,COD,BOD,CO2,Mg,… The analysis of Physical and Chemical factors of Mohammadiye channel water showed that except water temperature, all factors in comparison to the standards were at the standard level, So they are suitable for aquaculture. Due to mean of water temperature that is high from middle of Spring to the end of summer, It is suitable for culture of warmwater fishes and because of low water temperature in the station No1 It is recommended for culture of coldwater fishes by using of 50-70gr of young fishes
