Title

Indicators growth rainbow trout (Oncorhynchus mykiss) in earthen ponds with use of underground brackish water

Pages

  29-39

Abstract

 Because of the scarcity of fresh water resources in the country, the use of brackish and saline water resources for fisheries products is taken into consideration. In this study, Growth rainbow trout with Brackish water (14 ppt) extracted from underground water sources in the area Esferayen (North Khorasan) in Earthen ponds with an area of 3000 square meters with a good depth of 1. 8 m was studied. The period of pisciculture were160 days (autumn and winter). The number of primary fish stock in each earth pond was 23000 and average weight of fish 22. 7 ± 1. 5 g. At the end of rearing period, because of differences in the survival rate of fish in pond1 (82%) and 2 (88%), differences in other parameters were significant (P<0. 05). So that in pond of 1 and 2 were determined FE: 0. 88± 0. 02, 0. 82± 0. 02; CF: 1. 42± 0. 01, 1. 29± 0. 03; SGR: 1. 51± 0. 01, 1. 40± 0. 02% /day-1; PER: 2. 26± 0. 05, 2. 11± 0. 06; FCR: 1. 18± 0. 02, 1. 25± 0. 04 and FW: 390± 7, 340± 7 g. respectively. The results showed that, Oncorhynchus mykiss fingerling have good Growth in each pond with Brackish water, whereas have difference relative in Growth indicator.
