| 總結: | Fish farming in buckets is one type of aquaponic farming system that answers
the challenges during the pandemic. Water quality in the fish culture is influenced by
the population density of fish. The availability of oxygen in water is relatively lower
than its availability in the air and depends on solubility. Ceratophyllum demersum is
an aquatic plant that produces more oxygen and consumes less oxygen. The purpose of
this research is to determine the carrying capacity of the system, the availability of DO,
the rate of oxygen consumption, and a mathematical equation that describes the
availability of DO in the system. This research lasted for 28 days and used tilapia fish
aged 45 days and genjer aged 12 days after seeding. The results showed that the
carrying capacity of the fish culture in the bucket system is less able to support the life
of tilapia (Oreochromis niloticus) based on the availability of DO in the system. The
average DO concentration of the fish culture in the bucket system during observations
in the morning (8:00), afternoon (12:00), and afternoon (18:00) respectively, namely
the treatment of 3 fish 1.8; 3.8; 2.5 mg/L, treatment of 5 fish 1.3; 2.8; 1.4 mg/L,
treatment of 7 fish 1.2; 2.5; 1.3 mg/L, and treatment of 9 fish 1.2; 2.1; 1.1 mg/L. The
average rate of fish consumption from each treatment, including the treatment of 3 fish,
5 fish, 7 fish, and 9 fish, respectively 0.00139; 0.00111; 0.00085; 0.00108 mg/L/g
body/hour and the results of statistical tests showed a significantly different effect
between the rate of oxygen consumption and population density. The availability of
oxygen concentration in the bucket fish farming system during the study with 3 times
in the morning (8:00), afternoon (12:00), and afternoon (18:00) can be described by a
6th-degree polynomial mathematical equation with an R2 value of consecutively 0,98;
0.98; 0.99. |
