Bachelor Thesis from the year 2020 in the subject Biology - Zoology, grade: 3.87, , course: Bachelor of Science in Fisheries, language: English, abstract: In this study, intensive common carp (Cyprinus carpio) culture was conducted from 2nd October to 28th October in experimental cemented tank of 25 m2 of Fish hatchery complex, AFU to learn to produce common carp through intensive culture. Intensive culture is a system where fish are culture in a well-managed manner and this system includes small ponds, tanks, and raceways with very high stocking density. In this system, fish is almost completely fed on formulated feed and good management is undertaken for controlling all aspects which require proper growth. Production of common carp is increasing so, intensification of its production from extensive to semi-intensive and intensive aquaculture systems is a new trend. The stocking density was 250 fish at the rate of 10 fish/m2. Average body weight of 27.9±9.8 g fish were stocked in the tank and feeding was done at 3% of body weight. Feed was made from mustard oil cake (70%) and rice bran (30%), a feeding tray having an area of 50x50 cm2 was used for feeding. Sampling was performed at a ten days interval and feeding was adjusted accordingly. The average temperature, DO and pH of the culture tank of 5:30 am and 3pm was 28.7±0.9 and 30.2±1.2°C, 7.1±1.3 and 12.4±1.6 mg/L, 7.7 and 7.8 respectively which were within the suitable range for culturing. After harvesting, the total harvested weight of fish was 12.9 kg while total stocking weight was 7.4 kg. Mean harvest weight of fish was 54.4±28.6 g while mean stocking weight was 27.9±9.8 g. The survival rate of fish was 97.6%. The extrapolated GFY and NFY obtained was 72.6 and 30.8 t/ha/year respectively. The fish were handed over to Aquaculture farm, AFU which they will rear further in tanks and ponds. During culturing water was exchanged daily in the morning for maintaining proper water quality. Thus, the results suggested that common carp intensive farming is feasible in cemented tanks with good survival rate.
Autorenporträt
My name is Biplov Shrestha and I was born in 1997/02/27. I obtained my Bachelor's degree from Agriculture and Forestry University with 3.87 GPA in Fisheries. I have been involved in numerous survey works and research works such household survey regarding fish consumption and fish farming, its impact and sex reversal technique of tilapia by feeding MT feed along with experience of doing intensive common carp culture as a part of my bachelor's thesis. Currently, I am doing M. Sc in Aquaculture and during mean time I have done some review articles related to antimicrobial resistance in fish and coccidios in fish and I have been involved in teaching since 2020. Now, I am an eramsus scholarship holder and doing my master's in Aquaculture, Environment and Society. I will complete my master's in 2024 and in this master program I have to travel to different countries like Scotland, Greece, France and Netherlands or others.
