Study of Impact of Diet Conditions on Egg Laying Behavior of Zebra Fish

Zebra fish is one of the most used model organisms in biomedical sciences and other research fields. Despite the huge importance of having an efficient and high throughput zebra fish aquaculture, little is known on its specific feeding requirements and very few studies have focused on the impact of feeds on the overall fish performance throughout their lifecycle. At the end of the diet, the body mass index of the 60 mg arm was 1.5 fold greater than the 5 mg arm. The intervention also had a marked impact on fertility; breeding success and egg production in the 60 mg arm were increased 2.1- and 6.2-fold compared to the 5 mg arm, respectively. Mean spawning success was significantly higher in zebra fish fed diet 5 than in those fed diets 1‐ 4. Mean fertilization and hatching rates were higher in the fish fed diet 3 ‐ 5 than in diets 1 and 2. Zebra fish consumed commercial pellet feed only resulted in more viable offspring’s and grown better. Results suggested that commercial pellet is suitable in zebra fish culture for maximum growth and production of viable offspring in laboratory condition.
