اثرات جيره هاي غذايي مختلف در بازده تخم ريزي ماهي سيامي جنگجو (Betta splendens)

Different rations on spawning efficiency of Siamese Fighthing Fish (Betta splendens)

The effects of five different food including: blood worm, artemia cyst, artemia mass powder, gammarus mass powder, and ordinary commercial food were studied on Siamese fighting fish (Betta splendens) propagation efficiency during thirty days in a Randomize Totally Design with 4 times repeatition. Experimental plots had been consisted of twenty 30x30x40 (cm) aquarium which a pair of male and female brood stocks were introduced to each one. Male and female fish were separated in each plot by a glass plate for 15 days in order to get prepared for spawning. The results of experiment showed no significant difference on spawned ova, ova diameter, and hatched ova among various ration treatment, but the average of compared factors showed spawned ova, hatched ova, and ova diameter, were better in those brood stocks which had been fed by blood worm food treatment. However, ordinary commercial food treatment had the weakest results through all ration treatments.
