How does the River Runs Deep work?

Question

You might have never paid atention at Zao Steppe on your way to GT, but sometimes we can take a break to fish while waiting for the team.

World Board: The river in Zao Steppe runs deep, there may be more fish than usual!
Towncryer: Hear ye! Hear ye! In Zao Steppe the river runs deep. If you catch a strange fish it is yours to keep.

The dried up river in the Zao Steppe will run. During this time you will have the chance to catch several Sandfish.

Well Fandom is very short about achievements, but I would like to know more how to do this one and what's that about.

Use fishing rod at the same sqm works to fish a Sandfish?
Is there a cooldown for the same sqm give another fish?
Fishing there increase skill?
Does it count for Here, Fishy Fishy! Achievement?
What's the use of a Sandfish?
Is it related to any quest or lore?

Answer 1

So the process works more or less the same way as for normal fishing, but you have chance to catch sandfish.  As far as I know it's not used in any quest, but you can use it as a food source, quite a good one (regenerates for 11 minutes). Fishing there increase skill, yes. Not sure about the Here, fishy, fishy ach, but my blind guess would be it doesn't. Also catching sandfish requires more effort than regular fish, so it wouldn't be the most efficient way to do so.
