Analysis on the Feeding Habit of Tilapia (Oreochromis Niloticus) Cultured in Silvofishery Pond in Semarang
Silvofishery application in Semarang was expected to provide several advantages for aquaculture activity, such as its support to the availability of natural food for Tilapia. This research aimed to analyze the suitability of Tilapia fish stomach content and the composition of plankton in the silvofishery pond in Semarang. Data collection included plankton abundance in A. marina and R. mucronata silvofishery plot and stomach content of Tilapia fish. Data were collected through field sampling occupying 6 silvofishery plot (3 for each vegetation type) and 6 fish samples (3 from each vegetation types). Water sampling was conducted by filtering 10 litres of water to 100 ml. Plankton identification was conducted in the laboratory. The result showed there were 7 plankton species found in the stomach content of Tilapia fish. Six similar species were found in the A. marina pond and only 5 similar species were found in R. mucronata pond. There was no similarity on the community structure of plankton found in the A. marina pond, R. mucronata pond and stomach content of Tilapia fish. The plankton abundance of A. marina plot was higher than the plankton abundance of R. mucronata plot.
