Once out in the sea fishing, I heard a fisherman saying something like 'red sea' or 'black sea' when we weren't getting a good result. Also, I think it's called 'blue sea' or something when we have good catches. Does anybody know about this?
I'm only a casual fisherman, but we usually refer to a good 'patch' when out on a boat fishing and find a spot with plenty of fish. I've got a friend who has a favourite spot he calls the 'salad patch', because you catch such a variety of fish there.
Another expression is to 'bag out'. The 'bag limit' is the number of fish of a particular species you're allowed to catch in a day - if you bag out, you've caught your limit, and have to either fish for something else, or head home (it's never happened to me!).
good haul From The Free Dictionary, the definition of haul:
- (esp of fish) the amount caught at a single time
(Just now saw the comment of @Pantelis Sopaskasis)
It is possible that its a similar phrase to "Black Friday" or "I'm in the Red" as Black represent profit and Red represents debt. If one were catching plenty of fish one could liken it to making a profit in a business and say "black sea" or if one were not catching an adequate amount of fish like a business who's production costs are greater than their profit and losing money one might exclaim "red sea". I'm not a fisherman but the red/black concept has been used in many other similar circumstances.
