Depends on the species. It can be known statistically. If we have a fair estimate of how many seahorses exist in the wild, then given average brood sizes we can estimate the number of seahorses there WOULD be given a certain mortality rate among fry. Turns out that this number is pretty much in line with most livebearing fish.
Think about it... if an H. abdominalis gave birth to 10001500 young, and there were, let's say, 100,000 of males of these fish in the ocean, then every 28 days that population would increase by 1000% (first month there would be 100,000,000, second month there would be 100,000,000,000, and so on). With in a few months, the entire ocean would be teeming with Pots!!! Nice thought, but Mother Nature would NOT approve! Related Topics:
