Identification of Causative Agent for Fungal Infection and Effect of Disinfectants on Hatching and Survival Rate of Bata (Labeo. Bata) Larvae

Abstract: Labeo. bata is one of the most important cultured fish. Intensive incubation leads to microbial overgrowth in L. bata eggs that hamper egg development hatchability and larval survivability. The aim of this study is to find out causes of mass mortality in L. bata eggs during peak breeding season from 10 March to May 2015 at Mafatema Fish Hatchery Jessore Bangladesh. Three concentrations of four chemical-formalin (10 20 30 mg/L) malachite green (135 mg/L) NaCl (123 g/l) and methylene blue (135 mg/L) treatment re… Show more

“…The highest hatching rate of barramundi eggs within 14 hours of observation in treatment P3 with a dose of 4 ml/L was 90.33%. The value of the egg hatching rate obtained in this study almost coincides with 92.33% with the value of the hatching rate of eggs from research results [26] on the effectiveness of using chemical disinfectants to Prevent fungal attacks on Labeo bata fish eggs. The dosage of 4 ml/L is the dosage containing active ingredients such as alkaloids, flavonoids and other antifungal substances that are completely optimal and suitable for barramundi, so at this dosage the eggs hatch well.…”
