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 live-bearing fish.
Think about it... if an H. abdominalis gave birth to 1000-1500 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:
