“…Incubation period depends on species and incubation temperature. According to Aktar et al [5], incubation period of various warm water fish species varies, ranging from a minimum of 12 to a maximum of 72 hours. Valeta et al [6] also discovered that the incubation period tends to decrease with higher incubation temperatures.…”

The study was carried out to investigate the induced breeding practices and variations in effective hormone dosage used in induced breeding procedures in three different fish hatcheries of Kurigram District of Bangladesh. The hatcheries mainly produced carp fish seeds, including five native fish species such as Rui (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus mrigala), Bata (Labeo bata), Punti (Puntius sarana) and four exotic fish species namely Silver carp (Hypophthalmichthys molitrix), Bighead carp (Aristichthys nobilis), Grass carp (Ctenopharyngodon idella) and Common carp (Cyprinus carpio). Exotic carps were the highest produced fish seeds (38%) in the Kurigram district, followed by major carps (35%), Bata (16%), Punti (6%) and others (5%). Three main types of inducing agents including PG (pituitary gland), HCG (human chorionic gonadotropin) and Ovupin (GnRHa injection) were used for induced spawning. The rate of 1st dose of injection of PG, HCG, and GnRHa varied from 0.5 to 2 mg/kg body weight, 100 to 200 IU/kg body weight, and GnRHa (only one dose) 0.2 to 0.4 ml/kg body weight, respectively. The rate of 2nd dose of injection of PG varied from 2 to 12 mg/kg body weight. The PG is usually primarily used for first and second doses; the ovulation period of different fish species varied between 12 to 72 hours, whereas the hatching rate ranged from 70% to 95%. Due to the variations in inducing agents and doses, different ovulation, fertilization, and hatching rates were observed.

“…In case of rui, catla, grass carp and common carp, 0.5 mg/kg, and silver carp, bighead carp, 0.75 mg/kg body weight of PG for first dose in female and 1-2 mg PG/kg body weight in male fishes were injected. Akter et al [14] and Akter et al [15] adopted more or less the similar practices for induced breeding in various fishes. For the 1st and 2nd dose, PG of 0.25 mg/kg and 4 to 4.5 mg/kg, respectively was used for sharpunti and bata.…”

An investigation was carried out to know the induced breeding techniques of some firewater fish species such as rui (Labeo rohita), catla (Catla catla), silver carp (Hypophthalmichthys molitrix), grass carp (Ctenopharyngodon idella), common carp (Cyprinus carpio), bighead carp (Hypophthalmichthys nobilis), sharpunti (Puntius sarana) and bata (Labeo bata) at Ma Fatima Fish Hatchery in Chanchra, Jashore, Bangladesh. The cost-benefit analysis was also performed on this hatchery for three months from May to July, 2016. The brood fishes purchased from different local sources were used for spawning. The hatchery mainly practiced induced breeding by maintaining proper age and weight of brood stock during spawning. The ranges of fertilization and hatching rates of the experimental fishes were 80.04±1.44 % to 94.35±0.54% and 75.34±3.49% to 88.68±2.76%, respectively. Total spawn production was 960, 862 and 734 kg, and the total revenue income from spawn sell was BDT 2,883,500, 2,355,100 and 1,844,800 (BDT 85 = 1 US$) in May, June and July, respectively. Estimated capital cost was BDT 87,90,000, while the operating costs were BDT 1,810,650; 1,555,105 and 1,267,680 in May, June and July, respectively. The calculated cost-benefit ratios in May, June and July were 1.59, 1.51 and 1.46, respectively. The hatchery got the highest net profit of BDT (Bangladeshi Taka) 1,041,906 in May due to the highest production and higher price of spawn, and the lowest profit of BDT 546,176 was obtained in July. So, May was found to be the peak breeding month of Ma Fatima Hatchery. The estimated cost-benefit ratio indicated that the spawn production through induced breeding techniques was profitable for the hatchery owners.

“…For various catfish species, different hormones are utilized at different levels, which may have led to worse fry and fingerling quality as well as decreased hatching and survival rates. Pituitary gland (PG) extract was often not used in the hatchery, especially for catfish because of the low ovulation rate and high requirements (Mondol et al, 2014;Aktar, 2015;Verma et al, 2017;). Finding the right hormones at the right dosage is crucial for studies on artificial propagation since it increases the chances of fertilization, hatching, and survival rate.…”

An experiment was carried out to identify the perfect dose of Flash hormone for induced breeding of Mystus cavasius at the Reliance Aqua farm hatchery during the period from 29th June to 25th August, 2015. Three treatments (T1, T2, and T3), each with three duplicates, made up the experiment. From the brood rearing ponds, 45 pairs of female and male were selected, with a male to female sex ratio of 1:1. A single injection of Flash hormone, specifically 0.166, 0.125, 0.1 ml/kg body weight for males and 0.33, 0.25, 0.2 ml/kg body weight for females respectively in three treatments, was given to the brood fishes. The T1, T2, and T3 treatments showed a fertilization rate of 79.0, 88.7, and 77.51%, a hatching rate of 56.61, 60.03, and 37.78%, and a survival rate of 40.56, 50.86, and 32.07%, respectively. For all treatments, the incubation times for fertilized eggs were between 23 and 28 hours. The findings of the data analysis reported that the use of Flash hormone in T2 treatment resulted in the highest rates of fertilization (88.7%), hatching (60.03%), and survival (50.86%). When comparing the three Flash dosages, there were notable changes (P<0.05) in the rates of hatching, fertilization, and survival. A single dosage of Flash hormone (0.125 ml/kg body weight of male and 0.25 ml/kg body weight of female) in T2 was the hormonal combination that produced the greatest results for M. cavasius induced breeding.
