Bio-acoustic is a multi-discipline science that combines biology and acoustic science that usually refer to sound production research, sound dispersion through the elastic medium, and sound reception in animal; include in Guppy fish Poecilia reticulata. First- highest sound intensity of Guppy fish is after added of salt level at 3th and 7th day, with the average of sound intensity is dB at seconds of time range.
This research shows that Guppy fish can survive in salinity 30 ppm with sound intensity dB and frequency Introduction According to Subani and Barusthe food is tuna fish, sardines, trevally, mackerel, and lolosi. Tuna is very happy with a very prominent color in fish, thus bait alternatives should be made to resemble the lzju of the fish bait.
The guppy Poecilia reticulata is a small fish that have the pregnancy in the short term. This fish gestation period ranges from days average 28 daysdepending on water temperature.
The guppy Poecilia reticulata in the aquarium can reach a length of 6 cm, but in nature mostly only grow to about 3 cm. This size is too small to prey on mosquito larva. When the fish is found to various places in the archipelago, and may have been the most abundant fish in Java and Bali Wirjoatmodjo, The guppy Poecilia reticulata males have a color pattern of the body and fins are very bright and have a very lauj price compared with other ornamental fish Arfah ; Suwarsito et al.

Pictures male parent fish Guppy Poecilia digdsti can be seen in Figure 1. Study of Elle studies voice frequency range, the intensity amplitude of the sound, the sound fluctuations, and form sound patterns of fish.
Bio-acoustic is a cross-disciplinary science that combines biology and acoustics usually refers to a study on sound production, dispersion through elastic media, and reception in animals, including humans. This involves neurophysiology and anatomy for the production and detection of sound, as well as an acoustic signal relationship with the dispersion medium. The findings in this area provide evidence for us about the evolution of the acoustic mechanism, and from there, the evolution of animal use.
On underwater acoustics and fisheries acoustics, this term also means that the impact of plants and animals in the sound propagates under water, which is usually related to the use of sonar technology for biomass estimation Simmonds and MacLennan, Sullivan summarized the findings of various researchers on the effects of temperature and salinity on the distribution of diesti, and discusses the role of the mechanism of central nervous system receptors in the reaction temperature and salinity.
He stated that the fish chose certain temperature and salinity because the same effect on movement activity them, and concluded that changes in temperature and salinity typically work on fish: Tilapia included in the group of bony fish back that can produce sound through the bubble bathing. The sound is a form of communication among human beings produced voice grew stronger as gathered like at mealtime.
Guppies Poecilia reticulata is a type of fish that is small, with attractive colors Figure 1dihesti fish while moving produce noise spectrum resulting from flapping fins Stridulatory. Research purposes The purpose of this study is to analyze the activities of the characteristic sound of fish guppy Poecilia reticulata using Bio-acoustic, during acclimatization. Research methods The research activities carried out from April 16 until July The data collection activities carried out in the laboratory of Marine Acoustics Instrumentation AIKwhich is housed in a water tank.
Data capture and recording activities undertaken during the two weeks from April 20 to May 4, The tools used are the aquarium measuring 40 cm long, 30 cm wide and 30 cm high; aerator to assist in the circulation of oxygen in the aquarium; refractometer to measure the salinity of the water; Dolphin EAR hydrophones DE serial number which is a sound sensor; Wavelab dam MATLAB software is used to process the data; and a set of computers that are used for the storage and processing of data directly recorded sound.
Figure 2 is a set of voice recording device, while Figure 3 is a flow diagram of the study. A set of tools voice recorder: Stages of Iman 4. Preparation and Modification Aquarium The measures undertaken in the preparation stage the aquarium is: Lastly is the inclusion of water that has been added into the aquarium salinity observations.
Result of design modifications to the aquarium can be seen in the illustration Figure 4. Sketch recording set up the sound of fish guppy Poecilia reticulata. Sound recording fish done by using hydrophone then channeled to the amplifier, once that is done by using a voice verification seaphone.
The recording process using software Wavelab 6. Target data to be retrieved for analysis ie 14 times observation. Data records are stored in the hard disk for further analysis. Data recording is done whenever the addition of salt content. Results and Discussion Acclimatization is an attempt physiological adjustments or adaptations of an organism to a new environment that will be entered Hazarika Initial acclimatization process Guppy fish totaled 65 tails with an average weight of 1.
But after day 8 fish there are dying of 0. In total until the end of the observation, the relatively smaller fish deaths, namely nine tails 0.
Physical observations of fish in general during the acclimatization process fish change color to red.

According to Brettthis is due to the metabolic system damaged digewti fish, and things like this will cause the death ditesti the fish. The factors that cause the effects of death, namely the regulatory factor. Regulatory factors for each fish must be controlled, which is in the process of metabolism of the fish. If the system is broken then the fish metabolism reddish color will arise in the fish’s body and over time will cause death.
Total mortality in fish Guppy with salinity can be seen in Table 1. This is due to the reduced immune system of fish and fish decreased appetite. According to Brettthis is due to the metabolic system damaged in fish, which will cause the death of the fish. The factors that cause the effects of death, namely regulatory factors. Interpretation Salinity Relationship With Intensity Range The addition of salinity in an aquarium filled with fish Guppy leads to changes in the intensity and spectrum of the sound very different.
It is clear that there is a reaction that occurs in the movement of fish, shortly after the addition of salt the fish will have a sound intensity lower than, before adding the salt content in fish. According to Lugli et al.
Some species of fish have a sonic muscle that cigesti pressure on the swim bladder. This happens because the swim bladder of fish guppy will work faster. The recorded frequencies are ranging from 0 to Data shown on the graph is data ping of to The following shows four graphs fish sound intensity difference by the number of different Figure 5.
Based on the graph in Figure 5, the intensity of the sound after the added salt fish on day 2 had a digwsti intensity than the intensity after kadagar added salt on days 3, 4, and 5 with intensity values that is The intensity value before adding salt at day 1 have a very low intensity values, compared to the intensity values after adding salt.
The value of the intensity before being added salt has an initial value and the final value of The following graphs digesfi differences in sound intensity five fish with a different number. The results shown in Figure 6. Based on the graph shown in Figure 6, it is clearly visible intensity value after the salt is added on day 6 and to 8 have almost the same intensity so it looks like override the line generated by the MATLAB figure.
Intensity values on day 9 have the stability of the intensity with the period ranging from seconds to 58 with the final value of the frequency is While on day 7 after the addition of salt has a very high intensity value is the initial value and the final value of The following graphs show differences in sound intensity six fish with a different number.
The results shown in Figure 7. Based on Figure 7, it is seen the intensity values before adding salt at day 1 is much different. The intensity value before adding salt after salt is added on days 10,13, and 14 have almost the same value with the initial ilan value of dB and the final value is The intensity value before adding salt at day 1 value at the beginning of While the value added salt to the intensity after 12 days seem to have the intensity dlgesti that are in the middle. While the value of the intensity after day to 11 have the lowest intensity value with a second period that the initial intensity value is dB and the final value is It is clearly seen that the guppy fish do very little movement, causing the intensity of the sound of fish guppy has little value.
According to Syahroni the large number of real berperangaruh fish with a value of intensity and frequency generated so that the value of the intensity and frequency is proportional to the amount of fish, and according to W. Sri Mahendra and fish which have high productivity has a range of frequencies and intensities narrower, compared with fish that have lower productivity and intensity with a frequency range wider.
The guppy has a range of intensity after the final value added salt which is a high intensity range, thus adding to the salt levels can cause fish Guppy Guppy fish have a lower productivity than before adding ikxn. Guppy fish can survive in waters that are very vulnerable condition with death.
In general, fish decreased the intensity range after the addition of salt content.
Range intensity, 29 dB up to 33 dB before the addition, and 24 up to 31 dB after the addition of salt levels, with a frequency range from 0 to References  Arfah, Lsju. Environmental Factors and Growth.
