“…From the investigational study, it was observed that fry production are not sufficient than production capacity. More or less similar observation was found in the study of Bhuiyan et al (2011), Islam et al (2002 and Hossain and Siddique (2009). The annual production capacity (kg) of the surveyed hatcheries ranged from minimum 115 to maximum 2,500 kg.…”

.04 kg were recorded in the surveyed hatcheries. Two types of hormone injections PG (pituitary gland) and HCG (Human chorionic gonadotropin) were used for induced breeding. The rate of 1 st dose of injection of PG varied from 1 to 2 mg/kg and HCG from 100-150 IU/kg and the rate of 2 nd dose of injection of PG varied between 5 and 8 mg/kg. The incubation period and hatching rate in different fish species varied from 10 to 72 hours and 55% to 80%, respectively. The average total cost, gross return and net profit of the hatcheries were 0.667±0.798, 1.152±1.636 and 0.485±0.846 million BDT respectively.

An investigation was conducted during the period from March to December, 2009 to know the status and fish seed production of the hatcheries of six upazilas of Rajshahi district. All the hatcheries were established during 1968 to 2003. The occupations of the hatchery owners are hatchery business and others. Training status of the hatchery owners shows that in maximum cases they had no training and other cases had short term training, consulting with UFO etc. Funding source was self and loan, land ownership was own and lease. Fish disease occurs seldomly. The area of hatchery buildings ranged from 5 to 33 decimals. The water carrying capacity of overhead tanks ranged from 9091.90 to 409135.5 liter. . The number of permanent workers ranged from 2 to 6 in all seasons. Six native species (rui, catla, mrigel, calibaush, bata and gonia) and six exotic species (silvercarp, bighead carp, grass carp, common carp, Thai pangus and Thai puti) were used for seed production. Two types of hormonal injections, such as Pituitary Gland (PG) and Human Chorionic Gonadotropin (HCG) were used for this purpose. Average fry production were for rui, 140. 38 ± 127.02 kg, catla, 37.25 ± 29.24 kg, mrigel, 105.63 ± 54.84 kg, calibaush, 13.50 ± 5.75 kg, gonia, 32 ± 0 kg, bata, 166 ± 113.27 kg, silvercarp, 132.38 ± 96.32 kg, bighead carp, 120.71 ± 116.62 kg, grass carp, 31 ± 11.53 kg, common carp, 140.83 ± 93.83 kg, Thai pangus, 10 ± 0 kg, Thai puti, 42.33 ± 33.71 kg was recorded in some surveyed private hatcheries. The total fry production in some surveyed hatcheries ranged from 85 to 1698 kg with an average of 662.75 ± 513.83 kg.

“…2001). Information on the use of different feed sources, their percentage composition and effects on different cultivable species of fish are available from many workers (Springate et al, 1985;Santiago et al, 1988;Haque, 1991;Islam et al, 2002;Haque et al, 1996;Mollah, 1996).There are several limiting factors affecting the aquaculture industry in Bangladesh, including infectious diseases, nutritional disorders, environmental pollution and some managerial factors. In a recent study, Boglione et al (2001) showed that only 4% of wild caught animals are affected by body deformations.…”

Abstract:Labeo bata is one of the important minor carps in Bangladesh with great demand as good table fish. The study was conducted to observe the breeding performance at different management practices in Mafatema, Rupali, Modhumoti and Anan fish hatchery and disinfection treatments of water, eggs and fry in Jessore, Bangladesh during 10 March 2014 to 15 May 2015. An improvement in broodstock nutrition and feeding has been shown to greatly improve seed production. Protein and lipid percentage of broodstock diet have been identified as major dietary factors. Protein level was 24.77%, 23.47%, 18.08%, 17.78% and lipid level was 11.07%, 9.50%, 7.74%, 8.14% in Mafatema, Rupali, Modhumoti and Anan fish hatchery respectively. Three concentrations of four chemical-formalin (10, 20, 30 mg/L), malachite green (1, 3, 5 mg/L), NaCl (1, 2, 3 g/L) and methylene blue ( 1, 3, 5 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. Highest correlation value between absolute fecundity and body weight (r=.938, p<.05) and total length (r=.891, p<.05) and gonadosomatic index (26.2%) were found in Mafatema fish hatchery among four experimental hatcheries at 24.77% protein and 11.07% lipid level. Better fertilization rate (84.2±5.17%) and hatching rate (82.0±4.30%) were found in Mafatema and Rupali fish hatchery respectively that has significant difference (P<0.05) from that of Modhumoti and Anan fish hatchery at higher protein and lipid level. Lowest deformity rate (6.05+2.65) was observed in Mafatema fish hatchery that was significantly different (P<0.05) from that of Modhumoti fish hatchery. In case of disinfection treatment, methylene blue at 1mg/L bath treatment daily for 4 days showed significantly higher hatching rate (92.33±3.51%) and survival rate (94.33±4.73%).
