“…Similar results documented in different studies indicating enhanced fecundity and higher egg quality with increasing female brood age, such as in Nile tilapia Oreochromis niloticus Linnaeus, 1758, common carp Cyprinus carpio Linnaeus, 1758 [8,9]. and Indian major carp Labeo rohita Hamilton, 1822 [10]. Along with the age of broods, hormonal doses have a critical influence in the induced breeding of most fishes.…”

The age of brood fish is an inevitable factor in induced breeding technology worldwide. This study aimed to determine the optimal age for M. tengara for induced breeding and identify the most suitable age based on hormonal doses. Three age groups (1, 1.5, and 2-year-old) of brood fishes were used as three different treatments (T1, T2, and T3), with 0.8 ml kg-1, 1 ml.kg-1, and 1.2 ml kg-1 body doses of Ovasis (sGRnH) as the replications (R1, R2, and R3) of each treatment. Results showed that the highest mean fertilization rate (77.5 ± 1.73 %) was achieved in T1R2 for 1-year-old fish, while 1 ml kg-1 dose was ideal for them. For 1.5-year-old M. tengara, the highest mean fertilization rate was observed in T2R1 (79.25 ± 2.99 %) with 0.8 ml kg-1 dose being the most suitable. Two-year-old fish had the highest mean fertilization rate in T3R1 and T3R2 (76.25 ± 5.5 %) in June. Based on the fertilization rate and hatching rate, 1 ml kg-1 dose was identified as ideal for 1-year-old, and 0.8 ml kg-1 was suitable for 1.5-year-old M. tengara. Among all the treatments, T2R1 (1.5 year age, 0.8 ml kg-1) showed the highest hatching rate (78.25 ± 2.36 %) and most successful breeding performance over the study period, and June was identified as the best time for induced breeding. This scientific evidence provides valuable insight into the optimal age and hormonal doses for M. tengara in induced breeding technology

“…The M. pancalus was injected with two doses of ovaprim @0.25 and 0.50 ml/kg body weight of female and 0.5 ml/kg body weight of male observed the 100% spawning rate, 75% fertilization rate and 55% hatching rate (Hasan et al, 2016). The optimum dose of Ovatide hormone for induced breeding of Hemibagrus menoda is 2.5 and 5 ml/kg body weight of male and female brood sh respectively with ovulation rate of 100%, fertilization rate of 97%, hatching rate of 95% and survival rate of 85% (Hasan et al, 2021).…”

Induced breeding of Macrognathus aculeatus was carried out in order to determine the most appropriate dose of carp pituitary extract (CPE) and OVAFISH hormone. The best dose of CPE was 100 mg/kg body weight of female and 45mg/kg body weight of male with fertilization rate 81.34% and the best dose of OVAFISH was 1.5 ml/kg body weight of female and 0.75 ml/kg body weight of male with fertilization rate 91.96%. The fertilized eggs were round, sticky, demersal in nature and greenish in color. The perivitelline space of fertilized eggs was observed in 17 min. The First cleavage appeared at 56 min after fertilization (AF), producing two equal blastomeres. The cell division was completed in 4.17h. The fertilized egg took 6.47, 10.54, and 15.12 h to reach morula, blastula, and gastrula stage respectively. The eggs were hatched 34.17h AF at 27-28°C. Five days old post-hatchlings were reared for four weeks in a 160 L tanks using four different diets i.e., artificial feed, mix zooplankton, artemia nauplii and egg custard. The finding showed that hatchlings fed on mix zooplankton had a higher specific growth rate (SGR) (9.60±0.25). The significantly higher mean survival rate was also observed in larvae fed with mix zooplankton (47.67±11.25%) followed by artemia nauplii (38.5±5.4%) and artificial powdered feed (18.17±3.68%) for 28 days experiment. Our finding suggests CPE best dose @ 100mg/kg body weight for female and 45 mg/kg body weight for male and best dose of OVAFISH @1.5 ml/kg body weight of female and 0.75 ml/kg body weight of male for induced breeding. While in larval rearing experiment highest survival and growth rate was obtained in the larvae fed with mix zooplankton for 28 days trial.

“…Fish production and marketing is the integral part for the socio-economic development of fishermen community in the agro-based country like Bangladesh (Haque et al, 2021). To protect fish species and expand fish output for future generations, researchers should look at conservation and aquaculture production tactics that could help fishermen make a living (Hasan et al, 2021;Bithy et al, 2012;Islam et al, 2011). Fishers are one of the most susceptible communities in Bangladesh and most of them are live from hand to mouth (Ali et al, 2014).…”

The current study was assessed the socio-economic patterns and trends of livelihoods of the Old Brahmaputra River fisher's community in the Jamalpur district from July 2021 to June 2022. The livelihood status was analyzed regarding age distribution, family size and composition, religion, marital status, education levels, living standards, diseases, healthcare, electricity, sanitation, drinking water facilities, fishing, and employment status. Most fishermen (45.76%) were 35-50 years old, with 91.53% were Muslim. The average family size for a fisher was medium, with 5-7 members. 33.9% were illiterate, 37.29% could only sign, 20.34% finished primary school, and 8.47% completed SSC. Most fishermen had tin roofs 59.32%, straw roofs 22.03%, semi-paka houses 11.87%, and paka houses 6.78%. Approximately 45.76% of fishers relied on village doctors, 33.9% on the Upazila Health Complex, 8.47% on Kobiraj, and 11.87% on MBBS doctors. Approximately 93.22% of fishermen's homes were equipped with electricity. Fishing was the main activity for more than 57.63% of the fishers. Fishermen have suggested specific management strategies to halt the trend of decreasing fish catches and increasing fish production. These include restricting the use of harmful gear, prohibiting the catching of juvenile fish, creating fish sanctuaries, and releasing fish fry.
