This study used 10 rice lines and varieties,including the salt tolerant variety(Pokkali)and salt susceptible variety(IR29)as *** for screening rice salinity tolerance at seedling stage was conducted in hydroponic system using five different salinity concentrations(0,4,6,8 and 10 dS/m).Flowering stage was evaluated at the salinity level of 8 dS/*** experiment was designed in randomized completely block(RCBD)with three replications for each line/variety under non-saline and saline *** results showed that the growth of rice lines/varieties was retarded severely with increasing salinity levels,and almost all of leaves were drying and dead completely(score 7 and 9).Plants of IR29 and OM7347 were dead at the electrical conductivity(EC)=10 dS/m,whereas Pokkali(the tolerant variety)and IR93350 were evaluated at score *** stress caused the reduction of overall vigor of rice lines/varieties especially in the pollen germination,fertilization and grain *** lines/varieties were classified to salinity tolerance levels as following:IR5040,IR93350,IR86385-8D-1-2-B and Pokkali(tolerant);OM8104,IR93340 and IR93343(moderate susceptible);OM7347,IR87832-303-1-B and IR29(susceptible).

Adult rice field eels with 125.52±27.99 g body weight corresponding to 44.79±5.93 cm in length were maturity cultured in a 5 m^2 cement tank without mud for three months with density 30 eels/m^*** broodstocks were fed with three types of food including:sea fish(T1),commercial pellet food(T2)and mixed food—50%sea fish and 50%commercial pellet food(T3).Result showed that the maximum gonadosomatic index(GSI)of female eels fed by sea fish(2.89%±0.67%)was higher than both commercial pellet food(1.62%±0.62%)and mixed food(2.03%±0.82%)(P0.05).Maturity rate of female fed by sea fish(88.91%±9.64%)was higher than commercial pellet food(61.12%±9.64%)(P0.05).*** eels were induced for spawning with two kinds of hormones,including T1:human chorionic ganadotropin(HCG)at 1,500 IU/kg,T2:luteinzing hormone-releasing hormone(LHRH-a)at 150μg/kg and domperidon 10 mg/kg,and T3:control without *** results of spawning induction methods showed that the reproduction rate of female eels induced by LHRH-a and HCG hormones were higher than that by natural reproduction method(P<0.05).Others,the survival rate of fry eels after 5 d using natural reproduction method(92.65%±2.54%)was higher than both using LHRH-a(67.77%±1.91%)and HCG(68.65%±1.23%)hormones(P<0.05).The average diameter of eggs was 3.40-3.41 mm and the length of newly hatched eels was 1.72±0.19 cm.
