    Study of fish consumption per capita per year in rural and urban areas of Markazi Province, Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Survey method has been performed using questionnaire forms for study of fish consumption per capita per year in Markazi Province due to lack of enough data on this field in the said province. Each questionnaire was completed by asking questions from each of the families as a statistical population sample either in rural or urban areas. According to the national census in year 2008 by Iranian Statistical Center, there are 364564 families living in Markazi Province out of which 207802 (57%) families are urbanites and 156762 (43%) are ruralist. A sample with total population of 2525 families were chosen with 1455 families living in urban and 1075 families in rural areas. Systematic random sampling was adopted in both areas which show people consuming fish once in 25 days with 5.8 Kg as per capita and per year for the whole Markazi Province.

    The Study of nutrition and feeding position of shrimp, cultured in IRAN (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The culture of Iranian Shrimps began in Bushehr in 1372. Early the green or the pink tiger shrimp (Penaeus semisulcatus) which were found in most habitats of the Persian Gulf and Oman Sea were considered in breeding and reproduction, but due to reproduction difficulties, it was rather replaced by the Monodun imported species, then the production of the white shrimp Metapenaeus affinis and Then P.merguensis in some southern areas of the country such as Hormozgan has began in small scale,but none of these species couldn't meet the economical needs of the consumer society and they were not indelible and dominant enough in the shrimp aquaculture industry of the country until breeding of Indian White Shrimp (Fenneropenaeus indicus) has began in large scale in the provinces of Khuzestan and Bushehr, which are seen as the heart of shrimps reproduction and breeding, and in Hormozgan and Sistan. the incidence of white spot viral syndrome (White Spot Syndrom Virus) led to the import of the western white leg shrimp from the USA (P.vannameii) by the Iranian Fisheries Research Organization (IFRO) in 1383, at the present all southern and northern breeding farms of the country (fundamental measures has been carried out in line of shrimp reproduction in Gorgan province in 1386) has put the breeding of this shrimp species as the single breeding species at top of their agenda. The subject of feeding the breeding shrimps is widespread and regarding to the non-proprietary species there are still some species which contain high protein than the other species in studying the different shrimp species requirements. In Iran due to the scarce factories producing the shrimp's food, the alimentary compound of the breeding shrimps during industrializing years of this type of breeding even after the non-aboriginal western white leg shrimp species being inclusive was stable and through different biological processes including: Naplies which feeds from its yalk and by entry into zoa stage start eating only small-sized phytoplankton. And by entry into the stage between zoa and mysis it feeds from phyto and zooplankton simultaneously and entering the post-larva stage it stars sarcophagi. and after 15 post-larva stage entering the growth and transition stage to earthen ponds feeding by concentrated industrial foods in large and small packages depending on young and adult mouth and due to feeding requirements of every stage the alimentary compound is nearly as follows: Digestible protein, energy, fat, carbohydrates, vitamins and minerals will start and the final product will be released in market Or they will be used in the later years of laying eggs and feeding for brood stock. In feeding section the details of every stage and their food's nutritional needs at each stage and will be fully described.

    The effect of subacute concentrations of Butachlor herbicide on some blood parameters in rainbow trout (Oncorhynchus mykiss) (2017)
    Details
    Publication Date: 2021-05-19
    Description: The purpose of this study was to evaluate the effect of Butachlor on some blood parameters of rainbow trout (Oncorhynchus mykiss). 150 pieces of fish in five experimental groups (25, 50, 75, 100% dosage of LC50 and control) were exposed to various concentrations of the herbicide Butachlor for 6 days and changes in the blood parameters were studied. At the end of experiment, there were significant difference (p 〈0.05) between experimental treatments in terms of their number of red and white blood cells, hemoglobin and hematocrit values. MCV, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration. The number of red and white blood cells, hemoglobin and hematocrit values decreased with increasing Butachlor concentration. Also MCH and MCHC showed decreasing trend by increasing percentage of Butachlor. These two factors as well as MCH were significantly different in control compared to the other treatments. Regarding MCV, an insightful difference was observed between control group and other groups. Increasing Butachlor concentration reduced every studied factor eloquently. Moreover, in every factor except WBC, there was a significant difference between low (25%, 50%) and high (75% , 100%)concentration of the Butachlor. Evidently, change in different blood factors of fish under the Butachlor toxin had cause a reduction in their protection system and mortality.

    Investigation of breeding and culture in Iranian cichlid (Iranocichla hormuzensis) as endemic and ornamental species (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Iranian Cichlid is an invaluable ornamental species which is domesticated in Iran and called Iranocichla hormuzensis scientifically, is living in the Hormoz zone, Shahou River (between Bandar Abbas and Haji Abad). The first phase of the research project started in September of 2012 and lasted about 18 months, focused on adapting the wild cichlids to cope with the aquarium environment. Therefore, about 63 male and female of Iranian cichlids collected from the natural habitat, Shahou River, then moved to the nearest city, Bandar Abbas to and released in aquariums which were filled by water of River where they were living. After few days they moved to “innovative aquaculture technologies research station” and reared in 100 liter glass tanks to monitor their behaviors. By initial days, the Cichlids seemed to be stressed out significantly, they were flashing, hitting them to the aquarium, trying to jump out and get discolored due to strange environment. By days, the stressful treats decreased and the experiments coped with the new environment. At the next step, schools of 5-7 fish organized to pear up. The mortality rate collected daily and accidental biometry recorded fortnightly. The rearing temperature adjusted and was stable at 37˚C. Finally, the Cichlids were completely adopted and prepared for mating and breeding.

    Effects of trout farm activities on water quality of Taleghan dam and related rivers (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The result of chemical examination on samples demonstrates that most of assessed parameters met the environmental standards. The trend of BOD5 changes showed a decrease due to recreation of the rivers in the both studied points (1-4 stations of Khochireh zone and 5-8 Hassanjun zone). Therefore, aquaculture activities did not play a significant role in enhancing the instant organic load (p〈0.05). Investigating the amount of total phosphorous revealed that Khochireh zone owned less pollutant consists of phosphorous compounds in comparison to Hassanjun zone. Hilsenhoff was an applied to determining the amount of pollution of assessed rivers. Biological and chemical examination of the Hassanjun, Khochireh and the main branch of Shahrud River was organized and done in May, 2012 by fast sampling method. Also monitored levels of total phosphorous showed the both rivers experienced an increase in downstream compared to upstream. The trace of frequency variation of macro benthos showed that Chironomidae and Elmidae families which are from Diptera and Coeloptera orders considered as the most crowded populations of macro benthos in the study zone with the total frequency average of 11.6 and 10.0 per square meter. The result of studying on macro benthos based on Hilsenhoff biological index elaborated in Khochireh zone the activity of aquaculture industry (without any urban zone and other industries) led to deteriorate the water quality from average in station 1 to average –weak in station 2 whereas, fish farms couldn’t affect the quality of main branch of Shahroud river due to higher volume, so didn’t any significant change in third and fourth station. In the Hassanjun River at the upstream of the fish farm the water quality seems to be never appropriate, that be alleviated to average in downstream. The main branch of Shahroud River was affected due to admixture with hassanjun River; therefore turned the quality from very good in station 7 to bad in station 8, obviously due to the low quality of Hassanjun River. To conclude, the chemical and biological investigation illustrate aquaculture activity throughout the Shahroud River affects the water quality in an ignorant level which is offset by recreation ability of the river. However, other types of pollutants which are emitted by other industries decrease the water quality of studied zone particularly at the downstream and entrance of the Taleghan dam.
