Of the many eggs fish lay, very few reach adulthood. The eggs are preyed on by many aquatic creatures, and the hatched fry are still in danger of being eaten. Only by laying so many eggs can the species have a chance of surviving.
Do you mean "Why do fish lay so many eggs at one time? The reason fish lay so many eggs at one time is survival. The more eggs that a female lays the better chance more eggs will have a chance to survive.
fish eggs and young fish tend to have many predators that want to eat them so many of them don't survive. By laying large amounts of eggs, adult fish increases the probabilty that one of those eggs will survive to grow into a full grown fish and reproduce.
Marlin and Coral had many eggs because, in the wild, fish produce a large number of eggs to increase the chances of at least some surviving to adulthood. This is a survival strategy to offset the high mortality rates that eggs and young fish face from predators and environmental factors.
clown fish lay so many eggs because the eat them
Do you mean so many eggs? If so, that question is already answered.
Because the eggs will be eaten while they are the egss and will not survive so fish produce a large number of young to guarntee a good survival chance.
Because so many are eaten or damaged, so the more eggs the more chance of survival
It's a survival thing. Many eggs are eaten before they have a chance to hatch. Many are eaten shortly after hatching. The chances are that 9 of 10 won't make it the first week, then even if they do, their chances of survival diminish quickly.
They hatch from eggs so as many eggs that they produce in the nest.
chickens are larger they cant produce that many. also hens raise their young so they have a highersurvivalrate where frogs just lay the eggs and and leave same goes for fish and only a small % of them will make it to sexual maturity
In the wild most are picked off by other fish before they have hatched. After hatching a lot don't reach adulthood, so more eggs equals to more chance of adult fish spawning again!
Usually around 200 or so.
