To increase the chances of survival of the offspring and thus the species. Many, many eggs are eaten by other aquatic life so laying a large amount of eggs insures that at least a few of them hatch and have a chance to become adults and carry on the gene pool. It is important to remember though, that each individual animal is NOT trying to perpetuate the species (most animals have NO CLUE what species they are, much less how to continue it's survival!) Each individual is merely trying to reproduce...with the result being that it might get its OWN genes into the next generation.

Because many species prey upon fish, if the fish have a large number of eggs, it increases the chance that some of the offspring live long enough to reproduce themselves
