I'm referring to this


I want to use the transducer and the circuit embedded to it, and interface it to the Arduino, Can someone help me?

Post the make and model of the fish finder - can't see from the picture. Even better, post a link to the manual or datasheet for it that has info on what ports are available on the fish finder. Or a datasheet for the transducer if you want to connect it directly to the Arduino.

Doesn't look like that device as any kind of method to interface to something like a arduino, seems to rely just on human eyeballs to read the data. Trying to hack the internals for useful signals to extract information would require a detailed schematic drawing of the device, which I'm sure you will not be able to find as it's sure to be proprietary information.

How about, I'll just use the 200khz transducer in it, then I will build my own circuit that will drive the transducer and be readily available for arduino interfacing? Can you help me with that?

No, that would be a pretty advanced electronic project as the analog electronics needed to interface with a 'raw' ultrasonic transducer can be quite complex and would at a minimum require access to a detailed datasheet for the specific transducer. Typically driving a transducer (transmitting a pulse) is pretty simple assuming you know the transducer's maximum voltage, impedance, and frequency specifications, but receiving the return echoes usually requires a analog amplifier with AGC (automatic gain control) such that is amplifies the return signal(s) more as time passes as return signals get weaker and weaker the further away the detected object(s) are. This would not be an easy project unless one had good knowledge and experience with electronics in general and ultrasonic interfacing in particular.
