Piece Length Types on Fish Target Strength Model
نویسندگان
چکیده
Fish species can be identify using target strength (TS) model. The result of model compared with result from in situ measurement as benchmark. Selarboops (Oxeyescad) as commercial fish from South China Sea has been used. Lateral and dorsal X-ray of fish has been deployed to perform fish body and swim bladder morphology and then divided into a number of pieces for Kirchhoff-Ray Mode (KRM) model implementation. This model uses the various length types depend on length of pieces of swim bladder and fish body. The model has been successfully developed to identify the TS value for specific fish species. The results have been verified with results from in situ measurement.TS value from model is relatively similar with TS from in situ measurement which the difference is about 7 dB on types of r, s, and t.The result shows that type of t is better than others.

Target Strength Measurement of Myctophid (Benthosema pterotum) in the Oman Sea
Through a series of research cruises conducted by the R/V Ferdows-1 to assess Myctophid resources, using a SIMRAD EK500 scientific echosounder carried out the Target Strength measurement of Benthosema pterotum in the Oman Sea. The principal method was based on a direct in-situ split-beam measurement technique, which is implemented in the EK500 system. For real-time observations ,the target st...
متن کاملA method for evaluating the effects of biological factors on fish target strength
Understanding the relationship between fish biology and target strength potentially improves the accuracy of acoustic assessments. The effects of individual biological factors (e.g., length, tilt, and depth) on backscatter amplitude have been examined, but the relative contribution of each factor has not been quantified. Dimensionless ratios, which facilitate comparison of disparate quantities,...
متن کاملPotential acoustic discrimination within boreal fish assemblages
Differences in the acoustic characteristics of forage fish species in the Gulf of Alaska and the Bering Sea were examined using Kirchhoff ray-mode (KRM) backscatter models. Our goal was to identify species-specific characteristics and metrics that facilitate the discrimination of species using acoustic techniques. Five fish species were analyzed: capelin (Mallotus villosus), Pacific herring (Cl...
متن کاملAcoustic Model of Body and Swim Bladder for Target Identification
This paper discusses the Target Strength (TS) results offish from in situ measurement at the life sea habitat compared to acoustic model. In situ measurement of fish Selarboops (Oxeye scad) and Megalaspiscordyla (Torpedo scad) have been deployed using Scientific Echo Sounder. Laterally and dorsally X-ray imaged of fish have been deployed to perform fish body and swim bladder morphology. Length,...
متن کاملAcoustic backscattering by Hawaiian lutjanid snappers. 1. Target strength and swimbladder characteristics.
The target strengths and swimbladder morphology of six snapper species were investigated using broadband sonar, x rays, and swimbladder casts. Backscatter data were obtained using a frequency-modulated sweep (60-200 kHz) and a broadband, dolphinlike click (peak frequency 120 kHz) from live fish, mounted and rotated around each of their three axes. X rays revealed species-specific differences in...
