Abstract

Sea Anemone is a close relative of corals. It is one of the marine life that is favored by lovers of sea-water ornamental Aquarium. Its body form resembling sponges with a beautiful color on her body. This sea anemone is a software belongs to the animals of animal invertebrates (spineless animals back). However, in the cultivation of fish, Clown fish which is much used living coral. The use of excess numbers of Anemone coral reef ecosystems in a dwindling and threatened to extinction. The results of this research show that the vitality of the living surroundings Amphiprion oscellaris aquariums made by an ideal aquatic environment conditions is not affected by symbiosis with Heteractis magnefica. Amphiprion oscellaris fish maintenance doesn't need sea anemone to survive, so the use of sea anemone can be minimised and replacing with artificial Anemone akuaskap as a decoration.

Abstract

Fisheries acoustics has two main division namely active and passive acoustics. Various acoustic studies with active methods have been conducted to assess the relationship between acoustics with fish density, but combination both mactive and passive methods has never been done to the same fish aggregation. Combining these two methods is expected to deliver an information related to fish density and its trend with both active and passive methods. This study was conducted on tilapia (Oreochromis niloticus) in controlled condition of 50, 100, and 150 fish individuals with total length range of 10-13 cm. Active and passive acoustic data acquisition carried out for 15 minutes on floating net cage of 2 m × 2 m × 1.8 m in dimension using CruzPro PcFF-80 echosounder 200 kHz (active acoustics) and Dolphin EAR 100 hydrophones (passive acoustics). Active acoustic data is processed using Matlab R2013b to generate value of scattering volume (SV), while passive acoustic data is processed using Wavelab program to obtain the intensity of fish sound in frequency domain, then both are correlated to fish density. The results of SV measurements in fish amounted to 50, 100 and 150 individuals respectively were -45.898 dB, -45,887 dB and -45,888 dB, with the coefficient of determination (R2) reached 0.6583. There is an average decrease in SV in fish totaling 150 individuals suspected to occur due to shadowing effects, also due to small fish used. The highest and lowest intensity of fish sound of 50 fishes in frequency range 0-22 kHz were -28.306 dB and -64.582 dB, 100 fishes were -26.0793 dB and -64.5296 dB, 150 fishes were -28.5246 dB and -64.5679 dB.

Abstract

Whistle sound is generally used for echolocation purposes, while the sound of the blast-beat and whistles play a major role in internal and inter-group communication.The purpose of this research is to know the power spectral patterns and fluctuations in sound based on frequency and Power Spectral Density (PSD) of the sounds produced by dolphins and observing the position of dolphins , Noisy Time Domain (NTD) and behavior using underwater camera, and also comparing between time and sound spectrum. Data recording was taken at tha Safari Park of Cisarua Bogor in Indonesia, by taking data in show pool and show pool. The results showed that salinity before feeding time in the show pool with replication 1,2, and 3 has salinity value that is equal to 30 ‰. Data at the show pool before feeding with replications 1,2, and 3 has a salinity of 29 ‰. Power Spectral Density (PSD) of the whistle sound before feeding was different from one another, but it has the same frequency range. The highest intensity values is at sound whistle 3 before feeding time at the show pool with an intensity value of 28.03 dB with frequency interval of 14 642 Hz-16000 Hz. F-test at the show pool before meals has heterogeneous value. Treat before meals at the show pool has a value of P <0.001 and P <0.001. Value Noisy Time Domain have differences with each other and have a lot of different sound patterns. In general, there are real differences are evidenced by F test on a range of time at each whistle on physiotherapy and swimming pool show in the time before meals. The position of dolphins in a pool show more dominant and often in the bottom of the pool, the position of the dolphins affect the frequency.
