All that Rattlin' & Clackin'

I seriously am wondering if Barramundi do attack noisy lures out of pure agitation due to the irritating noise.

Sound travels faster in water vs. air by about 4 times through waves or vibrations. Hang on... can fishes even 'hear' in the first place?? They dont have ears.... or do they? Ok... I'm no fish scientist here but fishes indeed do have stuff in their heads called otoliths that vibrate and translate to information to the fish. Similar to the human inner ear, it also helps the fish to 'balance' itself. Of course, the other more visible sensory organ is the fishes' lateral line, which helps it detect movement and vibration as they bounce off its body. 

So whether or not the fish actually 'hears' the same sound and translates it to the same tone as what we 'hear' is anyone's guess - we'll need to first catch a talking fish and then ask if it hears the same Rattlin' Rap's tone as us. But one thing's for sure, the vibrations in the water do cause the fish to either fight (or strike) or flee.  

In the case of the big Barramundis at Semeling, somehow they had this liking for really loud, rattling lures when all other lures didn't seem to attract. I'd personally think they were really irritated more than hungry. 

Can you imagine a baby rattle shaking away non-stop in front of your face? 

1-2 minutes... Bearable. 

Try a good 15mins or more of continuous rattling... 

*RATTLE RATTLE RATTLE RATTLE RATTLE*......  "BOOOF!"

Get the idea?
