A: Probably with its beady little eyes. Or, more likely, it just ignores them like most other fry gets ignored by their careless parents.

Where did this come from? Did you actually place this thread, or tried to reply to some other thread and pressed the wrong button?

You must learn to recognise sarcasm. But there is a lot of truth in Boerseun's statement: fish usually aren't very caring parents, and the young are often left to fend for themselves. I went to the trouble of finding these interesting articles for you - you'll find the conclusive answer in one of them. But remember, this forum is for scientific discussions, and not for us to do your homework for you.

Mildly amusing Unc, but where did you get the idea that:

"If the number of fish is X, then each sex numbers about X/2. The chance of boy meeting girl is (X/2)(X/2). If their numbers drop 95% to one in 20, their meeting rate drops to one in 1600."

from? I suspect that your not one of the janitors.

Many fish are hermaphroditic to help even the odds a bit. (at least many marine ones are...Fresh water fish have much more confined ranges and not subject to the needs of such a system).

Cod feed off lower parts of the food chain. Those lower parts feed off cod larvae. A Grand Banks large cod pupulation dumped purely huge numbers of juveniles each mating season, swamping local appetites and providing a food resource for older fish. The contemporary all but destroyed cod population cannot glut predator appetites. Despite grand tales of Official Truth, Grand Banks' cod fishing appears to be permanently well and truly dead.

The simple solution is to forget about cod and introduce a survivable fish with economic value - something big, angry, reproductive, and valuable when harvested. Let's not forget that last parameter.
