Giant Bagarius

[Silurus]

The size isn't so unusual, though I didn't know you could catch something this size with electrofishing.

All I can think of now is a gargantuan indoor pond with a mammoth chiller. Pity they killed it.

As much as I love the look of Bagarius, that 'tongue' makes me think of Jar Jar Binks from Star Wars Episode 1

Is it a tongue? Meesa thinkin' its a swim bladder.

It may well be, it just looks like one... ;)

Oh and like the reference

Nice Goonch.

I likely do not know enough... but it made me sad. I too find it strange that such a weak-powered device landed this majestic animal.

Even though the article says "battery operated", they probably did not use one of the pulsed DC electroshockers used by biologists. The ones I've seen used here put out something like 1000 v (heavy duty automobile batteries plugged into an inverter/step up transformer), and you pretty much zap everything between the electrodes.

Right. I have no experience with elctrofishing but from the electrostatics/physics point of view, watts is energy. Electric energy is current times voltage. One can jack up the voltage all they like to 1000 or 1,000,000 V but the current, the device can produce then, would be diminished roughly by the same factor and it is the current that damages. Voltage by itself does not damage anything. It's just that high voltage can inject current into hard-to-inject-into materials. Injecting current into water does not requite any high voltage. So, if I wanted to get more fish/bigger fish, I'd probably reduce the voltage to increase the current.

Pedantic mode in hyperdrive: Energy is Power * Time. Electric POWER is current (amps) times charge (voltage). And yes, if you scale charge up then current goes down and vice versa, unless you scale it up by actually putting more energy into the generation of the electricity.

In electrofishing, one of the biggest problems is soft water (low conductivity). But the big, main rivers tend to have higher conductivity, so it's probably not that bad where these fish live, compared to the small tributaries.
