This is the usual strategy of animal which do not look after their young. It is a numbers game, if 1% of the eggs survive to produce adults then if yo lay 100 eggs then yo will end up with 1 offspring, if you lay 1,000,000 eggs, you will end up with 10000 offspring.

If you do not protect your eggs from predators then it is best to lay so many that some are bound (by chance) not to get eaten.
