Feasibility study on Indian carps aquaculture in I.R.IRAN
15000 juvenile Indian majour carps (Labeo Rohita,Cirhinus merigala, Catla catla) imported (2009) and transferred to the earthen ponds in Astaneh Fisheries Research Station , 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 12 ponds.specimens were separated to tree experimental categories: 1= (30%indian carp and 70% chinees carp), 2= (50%indian carp and 50% chinees carp), 3= (70%indian carp and 30% chinees carp) .single chinees carp production were used as control . 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 ofspecies and optimization of their compatibility were remind for futhre studies. The culture period was 6 month in the Khuzestan province. Once every 45 days by using signebeach net samples were taken from ponds and biometry tests were done.The maximum net production was observed at 50% situated treatment, with average weight 723. 3 kg per 1700 m2 ponds (4254. 9 kg ha). There is no significant differences between experimental treatments with each other and with control (P <0. 05). Mean final weight of Rohu in 3 experimental treatments were 1136, 1129, 1054 g and in Catla and Mrigal were 726,902, 839 g and 773,788,894. There was not significant diference between them (P <0.05). Survival rate in Rohu, Catla and Mrigal was 92%, 97% and 86% respectively. The maximum specific growth rate (SGR) of fish related to Catla (1.92) and the minimum SGR of fish was observed in Mrigal (1.45) .Also in accordance with the results of this study, the Indian carp fishes can able to adapt, grow and reach to market weight in the khuzestan province's weather conditions.
