“…It showed the best result (90% recovery of fish). The relevant results were found by the study of Sharmin et al (2016); Hossain et al (2016); Monir et al (2015); Chowdhury et al (2015); Ahmed et al (2015); Hasan et al (2015) and Borty et al (2016). Scott and Warren (1964) used 2 ppm concentration of methylene blue for complete destruction of fungal hyphae within 7 days treatment.…”

Effects of different chemotherapeutics were examined against experimentally infected stinging catfish Heteropneustes fossilis. Fish were collected from a fish market in Mymensingh, acclimatized for 7 days in laboratory condition from January to February, 2016 in aquaria at Fish Clinic of Bangladesh Agricultural University, Mymensingh, experimentally injured by using forceps and knife and waited seven days for the establishment of infection. Before starting chemotherapeutic trial, it was confirmed that the fish were infected with microorganisms by clinical diagnosis in laboratory condition. They showed hemorrhages and ulcerative lesions over the infected area. A total of 80 such experimentally infected stinging catfish having average body weight of 18 g were used for the experiment. Two chemotherapeutics: antibiotic, Eryvet (erythromycin thiocyanate INN, sulphadiazine (NaUSP) & trimithoprim BP) and antifungal, methylene blue were used in separate and combined treatment with three different doses of antibiotic. The same dose of methylene blue, 0.2 mg/l, was used for separate and combined treatment by antibiotic. Doses of antibiotic (Eryvet) were 0.8 g/10 kg body weight of fish, 1g/10 kg body weight of fish and 1.2 g/10 kg body weight of fish as lower dose, recommended dose and higher dose respectively. For combined treatment the above different doses of antibiotic and the same dose of antifungal were used. Water was exchanged regularly. The chemotherapeutic trial was conducted for 7 days and observation was continued for another 8 days to observe the effect of treatment. Combined treatment with the recommended dose of the antibiotic and methylene blue showed the best result where 90% fish were recovered. By the treatment with the higher dose of the antibiotic 70% fish were recovered. Antifungal treatment showed that 20% fish were recovered. All the fish in negative control aquarium died.

Common carp (Cyprinus carpio) is one of the commercially important and commonly cultured fish. In the hatchery intensive incubation leads to microbial overgrowth in C. carpio eggs that hamper egg development, hatchability and larval survivability. The aim of this study is to find out causes of mass mortality in C. carpio eggs during peak-breeding season between March to May 2015 at Mafatema fish hatchery, Chanchra, Jessore sadar upazilla. In the present study three disinfectants with three different concentrations in each such as methylene blue 1, 3 and 5mg/L., malachite green 1, 3 and 5mg/L., sodium chloride 1, 2 and 3g/L were used to observe the hatching rate of fertilized eggs and survival rate of larvae. Bacterial load of culture water was examined during the induced breeding of C. carpio with mycological examination of egg samples with different disinfectants. The total bacterial count fluctuated from 3.4 x 10 8 CFU/ml to 32.7 x 10 8 CFU/ml during the period of fertilization to 4days of hatching. The fertilized eggs infected by Saprolegnia spp. were appeared as tuft hairy like balls with a white cottony envelop. Among all the treatment 1mg/L methylene blue, 3mg/L malachite green and 1g/L sodium chloride showed significantly better (P<0.05) hatching rate 95·33±2·08, 88.00±2.64 and 92.33±4.04% respectively. The same concentration of methylene blue, malachite green and sodium chloride showed significantly better (P<0.05) better survival rate 95·00±4.35, 75.00±3.00 and 87.00±6.24% respectively. Finally among all the treatment 1mg/L of methylene blue showed significantly better (P<0.05) hatching and survival rate 95·33±2·08% and 95·00±4.35 % respectively. So 1mg/L of methylene blue is the best disinfectant for C. carpio fertilized egg treatment.

“…Higher concentration of formalin treatment gives lower hatching and survival rate. Use of formalin in very small concentration effectively reduced fungal infection in the eggs and fry of Clarias gariepinus but it originated negatively on hatchability of the eggs and formalin is effective in treating saprolegnia [19,[34][35][36][37][38]. 5mg/L concentration treatment of malachite green showed better result (hatching rate 83.67±3.51% and survival rate 87.33±6.51%) than other two lower concentration (1mg/L and 3mg/L) treatment.…”

“…One hour treatment of malachite bath at the concentration of 4-5 mg/l proved effective for the treatment of carp eggs infected with fungi Saprolegnia sp. [36,39,40]. Malachite green can prevent fungal infection of the eggs of Cyprinus carpio and tench which have been treated prophylactic ally [41].…”

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 regimes and a control were compared for efficacy in treating L. bata eggs to prevent fungus and bacterial infection and improve hatch and survival rate of fry. Physicochemical and microbial characteristics of culture water were examined during the induced breeding of L. bata besides mycological examination of egg samples with trial of treatment of different types of disinfectant. The total bacterial count fluctuated between 3.6×10 8 cfu/ml at initial time of incubation and 31.7×108 cfu/ml after 3 days of hatching. The infected fertilized egg by Saprolegnia sp. were appeared as tuft hairy like balls with a white cottony envelope that surround it which focally invaded the cytoplasm resulted in loss of the cytoplasm content and destructed envelops.
