Perbandingan Nilai Target Strength Ikan Gabus (Channa Striata) Dan Ikan Lele (Clarias Gariepinus)

---

Catfish has an elongated and slender body, with a relatively large head and a
wide mouth. Its skin is smooth and dark, often leaning towards black or bluish-gray, adorned with small white spots. On the other hand, snakehead fish boasts fine, greenish-gray scales with small black spots on its dorsal and lateral sides. Snakehead fish possesses well-developed swim bladders, whereas catfish has underdeveloped ones. The objective of this research is to measure the target strength (TS) values of catfish and snakehead fish based on their length and weight, as well as to compare the TS values between catfish and snakehead fish concerning their swim bladders using a splitbeam echosounder. The measurements were conducted ex-situ in a water tank, with the fish tethered using monofilament lines, maintaining a distance of approximately 1 m between the transducer surface and the fish. The results of this study revealed that the average TS value for catfish was -55.79 dB, while snakehead fish exhibited an average TS value of -50.89 dB. The higher TS value of snakehead fish can be attributed to their larger size in terms of length and weight. Additionally, snakehead fish's well-developed swim bladders played a role in this discrepancy, whereas catfish, despite having swim bladders, had them in an underdeveloped state and exhibited smaller dimensions in both length and weight.
