    Limnological study of the Kan River in the catchment area of the Persian Gulf Martyrs Lake (Chitgar), Tehran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study focused on identification phytoplankton, zooplankton, benthos, fishes and relationship between biotic and abiotic parameters at three stations in the Kan river during 2014. This study identified 19 phytoplankton taxa. The findings showed, the diatoms abundance were dominated in the river. The chlorophytes abundance were recorded the lowest abundance in this study. The nutrients and water temperature were the significant abiotic parameters to increase cyanophytes and chlorophytes abundance in the Kan river. This study identified 26 zooplankton taxa. The Rotatoria and Protozoa abundance were dominated in the Kan river. Based on CCA, there was no correlation between abundance zooplankton and abiotic parameters. The biodiversity index of plankton was between 1.8 and 2 and the lake situation is located in the mesotrophic category. The study of the Kan river fishes showed, only one endemic fish species Capoeta bohsei. The length (between 38 and 270 mm, average 144±86 mm) and weight (between 1.1 and 356 g, average 108.8±146.7 g) of the C. bohsei were varied during the study period. The 19 benthos taxa were identified. The Ephemeroptera was most abundant in the benthos groups. The classification of river based on biology indicator and environmental parameters confimed that water quality is located in the moderate category.

    Feasibility study on Intensive polyculture of chainess and Indian carps in I.R.IRAN (Giulan province) (2021)

    Description: 500000 juvenile Indian majour carps (Labeo rohita,Cirhinus merigala, Catla catla) imported (2004) and transferred to the earthen ponds in Shahid Ansari Carp Breeding Center , In order to assess the viability of rearing under the climatic condition of north part of Iran and also achieve some growth parameters from the larval stage to market size.The fry with 300 mg weight, were released in to 8 ponds.specimens were separated to tree experimental categories: 1= (Labeo rohita) , 2= (Cirhinus merigala) , 3= (Catla catla). fishes were fed with artificial food and also with the natural products of the ponds which were enriched with organic fertilizers, after being equally stocked in the ponds .During the experiment, oxygen level ,PH, turbidity, and temperature were measured . Monthly fry samples were taken, for weight and length biometrical analysis and also determination of the weight gain percentage, average daily growth rate, specific growth rate. Results have indicated adaptations and considerable growth in this species, with an increase from the initial weight of 300 mg to an average of 13.5±1.6 mg in 50 days period until the end of November for fingerlings. Also the average weight of growing phase (second year of production) was 647g. For Labeo rohita ,420 g. for Cirhinus merigala and 734g. For Catla catla. The special growth rate(SGR)in Roho was 4.51 %.and 3.9 % for merigal and6.2 % for Catla while for Chinees carps SGR was 4.9, 6.7, 7.6 and 5.8 for silver carp,grass carp, common carp and big head respectively. Results revealed that the Indian majour carps compatibility with the condition in Gilan province was succesfull and the combination of species and optimization of their compatibility were remind for further studies.
