AbstractSimulated transportation of rainbow trout Oncorhynchus mykiss fingerlings to study stress reactions the effects of Lidocaine hydrochloride and Caryophillium aromaticus on water quality parameters Dissolved oxygen (DO), ammonia nitrogen (NH4+) and pH of control group and treated group of 5, 10, 20 ppm Lidocaine hydrochloride and 5, 10, 30ppm Caryophillium aromaticus similar experiments simulating the park et al (2009) of Winter flounder Pleuronectes effected Lidocaine hydrochloride Done separately for each period of 5 hours in 3 replicate samples in the results relative decline DO 4.42 ppm and increase NH4+ 0.45mg/l after 5h without loss of sample groups Lidocaine hydrochloride but increase NH4+ 2.04mg/l and the sharp decline DO 2.10ppm after 5h caused the juveniles were suffering losses %100 due to the high concentration of anesthetic Caryophillium aromaticus shock and did not leave. The purpose of simulating long-term transport juveniles Oncorhynchus mykiss separated by an anesthetic Lidocaine hydrochloride and Caryophillium aromaticus measure strength and economic of these results is non-toxic and effective anesthetic being also group 20 ppm Lidocaine hydrochloride is an effective rate in the Caryophillium aromaticus 5 ppm and control group critical condition operations metabolism excretion are juveniles Oncorhynchus mykiss.

Abstract[1]
This study was conducted to evaluate diazinon pesticide impact on some hematological indices in rainbow trout fry in Dr. Keyvan,s Research Center for Fisheries Sciences & Marine Technology (Islamic Azad University, Lahijan branch, Chamkhale port). During one week 120 pieces rainbow trout fry were exposed to three different consentration of Diazinon including 25, 50 and 75 percent of its LC50 (LC50=1.65 mg/lit) in 3 experimental groups and one blank group (by three times replicates) by O.E.C.D method. Exposed fry fishes showed some signs including neural paralysis, imbalance, abnormal swimming, severe impatience and paleness. The result showed that the number of leukocytes, erythrocytes, haematocrit and hemoglobin significantly decreased (P<0.05), but the amount of MCV and MCH increased significantly by 50% and decreased again, lymphocyte increased significantly by 50% and then increased by 75%. Resulted changes in erythrocyte & leukocytes after exposing with diazinon is due to malfunction in hemopoiesis and decrease in non-specific immune system.

Abstract[1]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.* Corresponding Authors; Email: salamyaran60@yahoo.com
