    The Study and Feasibility of Down Stream Area of Yamchi Dam for Aquaculture Development in Ardabil Province (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The research conducted for finding of aquaculture potential and appropriate areas of Yamchi dam downstream river and estimate of its production in 2010-2012. This research done by using of available information and data obtained from the monthly and seasonally sampling. Results showed that river access routes of left side to right were more suitable. The maximum distance of infrastructure facilities was one kilometer. Climate and weather data suggests that downstream area Yamchi dam was not suitable for warm water species aquaculture, while it was ideal for coldwater aquaculture. Also, physical and chemical results showed that almost all of the factors were suitable for growing trout. Heavy metals amounts were measured in the standard limit and iron, cupper, zinc, lead, chromium, cadmium and nickel had highest values, respectively. Bacillariophyta branch abundance of phytoplankton was dominant as showed suitable water quality. Benthos investigation demonstrated that the aquaculture activities is acceptable. In ichthyology studies identified 5 species Cyprinidae and 1 species Nemacheilidae family. Investigation of available underground wells and geophysical studies showed that alluvium area is made up from two parts of clayey surface ground and underground with good permeability and the lower part is affected from the upper part. In areas where both part of the alluvium formed there is a water layer about 20 to 30 meters thick as it is possible to build wells. But in areas without lower part faced with unreliable surface water layer that affected from river flows. Totally, varius method suggested for trout culture include of race way, octagonal pond and semi-recircultaion. In the present condition of Yamchi river the amount of trout production is predicted at least 65 ton by race way to maximum 1750 ton by semi-recircultaion method. Whiles, if 2 cubic meters of water from Yamchi dam outlet allocated to aquaculture can be predicted at least 580 ton by race way to maximum 4000 ton by semi-recircultaion method.

    The Study of Rearing Density Effect on Growth and Survival of Fingerlings Kutum, Rutilus kutum, with Caspian Sea Water (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Rutilus kutum is one of the most important economic fish species of Iranian costal of Caspian Sea. This species conducted more than 60% of fish caught in Caspian Sea annually, and more than 10 thousands fisherman engaged to its fishery. In present study, kutum fingerlings reared in two different densities include of 25 and 40 fish/m2 with mean weight of 17.5 ± 5.87 g. The period of test being planned 10 weeks and the test organism housed in circular concrete pools of 3 m3 capacity with flowing water and aeration in pools are supplied. The fishes feed by extrude food with 45% crude protein and 14% crude fat. After termination of the experiment, the result showed that weight gain performance, specific growth rate, condition factor, food efficiency rate and protein efficiency rate decreased, while food conversion ratio increased with rising of density, as their different was significance in two experimental treatments (p〈0.05). The kutum reared in low density showed significantly higher survival rate (SVR) (with 88.8%) than high density (with 76.9%) (p〈0.05). Based on the different observed effects of the density on growth and survival, it is recommended the use of a 25 kutum/m2 density for rearing by Caspian Sea water.

    The study and feasibility of Cheshmeh-Ali River and down stream area of Shahid Shah-Charaghy Dam in Damghan for aquaculture development (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This research was conducted to finding of Cheshmeh-Ali and Shahcheraghi-Dam downstream areas potential for developing of aquaculture industry. The present study was conducted based on available information and data from monthly and seasonally sampling including geographical area, margin lands and fluctuations of river water, seasonal climatic changes view point of rainfall, temperature, wet, evaporation, wind velocity, sunshine hours, frost and also chemical and physical parameters of water including temperature, alkalinity, total hardness, chloride, calcium, magnesium, sodium, potassium, organic phosphorous and nitrogen, suspended solids, turbidity, water flow and flood conditions, and in addition phytoplankton and zooplankton communities, macrobenthic invertebrates, fishes, aquatic plants, amphibians, reptiles, birds. Results showed that the upstream and downstream regions of Shahcheraghi dam are not suitable for warm water aquaculture in earthen ponds. But view point of cold-water aquaculture, particularly trout, there are some good situations. Also it can be suggested different culture systems including of race way, octagonal concrete ponds, semi-circulation and circulation methods. But, due to water restrictions in the area, semi-circulation and circulation system is preferred. In ideal conditions can be produced about 1,600 tones of trout, if all the capacity of this area be used for aquaculture. Otherwise, in limited circumstances view point of exploitation possibility of the water, only about 700 tons can be produced. In addition, there were appropriate facilities in spring area of Cheshmehali for tourism industry, that it can be considered as priorities for economic development in the region. Due to the low sensitivity of the ecologically conditions, native or exotic aquatic species rearing in indoor methods can be recommended.

    Description: The Kutum, Rutilus frisii kutum, is one of the most important bony fishes in Iranian coastal of Caspian Sea. Its harvest range is between 9000-10000 tons in a year, nearly 60% of the income of Bony fish fishery produced by kutum fishery. The stock of this species reduced drastically in 1982 and the catch slumped to the less than 250 tons in a year. Kutum spawning grounds deterioration, illegal catch, and lack of restocking program were the main cause of the decline. This Spices in nature comprised by two distinct form, autumn and spring form. It is worth to be mentioned, by the effect of Caspian Sea Bony fishes Research Center s experts in 1983, artificial spawning and releasing the fries to the sea were commenced and the catch steadily improved. But all activities concerning restocking of kutum concentrated in spring form, as at present about 260 million its fries are released into sea for restocking by Iranian Fisheries Organization, but for above reasons and lack of restocking program, the populations of autumn form gravely shrinked and neared to be extinct. Therefore, to enhance the biodiversity and boost fishers livelihood of kutum in Caspian Sea this project implemented by cooperation of Iranian Fisheries Organization (IFRO) and Caspian Environment Program (CEP) in Aquaculture Institute (Inland Waters). In this project, brooders caught from Anzali lagoon and maintained in two different condition, include of floating cages in Anzali lagoon and earthen ponds in Sefidrud Fisheries Research Station. The results showed that there weren’t significant differences between two maintenance statuses in maturation period and other reproductive characteristics of brooders. The ratio of male to female was 1 to 1.4. Minimum and maximum weight measured 1450 to 3100 g (with average of 1850 g) in female and 670 to 1900 g (with average of 1165 g) in male, respectively. The first natural spawning of brooders occurred in the end of January in temperature of 8 till 10 °C in concrete ponds. Also, some of maintained brooders in earthen ponds spawned in February. The average number of absolute, function and relative fecundity determined 88565 16809, 73805 14008 and 48670 12056, respectively. For artificial spawning, male and female brooders injected by pituitary gland with dose of 2-3 and 4-5 mg/kg body weight, respectively. Approximately, 10 and 8 present of female were over-ripe and immature in March (artificial spawning time), respectively. More than 59 % of injected female brooders induced to spawning in first stage after 10-12 hours and 13 % of them in twice stage and 7-8 hours after first stage. And also, 27.6% of females didn’t positive response to injection. Dry method used for eggs fecundity and incubation period lasted 7- 10 days in 14-16 °C. In totally, eggs fertilization were more than 95% and the average of eggs fertilization percent in throughout of period measured more than 92.7 6 %. Eyed eggs appearance occurred 3 days after fecundity and its mean was 92.7 15.1%. Larvae after yolk sac absorption feed with dry milk for 4-5 days and then introduced into fertilized earthen ponds (500 m2 and equipped to aerators) in intensive condition and fed with micro pellet food for 3-4 month. In finally, more than 1.8 million fries of 1-2 g and some more than 5 g produced and released into Anzali lagoon to its restocking for first time. It is expected that continuing of restocking process of autumn form kutum by Iranian Fisheries Organization eventuate to population increasing of this form in Caspian Sea in future.
