Do seahorses breed in captivity?
Seahorses breed more readily in the aquarium than any other marine fishes. Males and females are easy to sex, form permanent pair bonds, and breed continuously throughout the year in captivity, often re-mating scant hours after their latest brood has been delivered.
How does seahorse reproduce?
Male seahorses are equipped with a brood pouch on their ventral, or front-facing, side. When mating, the female deposits her eggs into his pouch, and the male fertilizes them internally. He carries the eggs in his pouch until they hatch, then releases fully formed, miniature seahorses into the water.
How many seahorse babies survive after birth in captivity?
Fewer than five infant seahorses in every 1,000 survive to adulthood, which helps explain why the litters are so large, said James Anderson, manager of the seahorse program at the National Aquarium in Baltimore.
How often do seahorses reproduce?
BREEDING: Dwarf seahorses form monogamous pair bonds that are reinforced each morning with daily greeting rituals. Males give live birth to three to 16 fully formed, quarter-inch-long young after a 10-day gestation period. Males carry two broods per month and the mating season runs from February to October.
How long does it take for a seahorse to reproduce?
The process of seahorse reproduction is very interesting. Studies show that the males and females will court for several days. During that period of time they will seem to take part in dancing rituals. They will be seen swimming side by side at the same pace.
Why are seahorses so hard to keep in captivity?
Breeding seahorses in captivity is a problem, in part because the babies are so tiny it’s hard to keep them alive. The marine scientists in Baltimore are working to develop effective methods that will help ensure the creature’s survival. The male seahorse has a pouch on its stomach in which to carry babies—as many as 2,000 at a time.
How does male pregnancy give Seahorses an evolutionary advantage?
Scientists are not sure what evolutionary advantage male pregnancy gives seahorses. One theory is that it enables a shorter cycle of reproduction by distributing the costs of the process between the two partners. While the male is bearing the young, the female can prepare more eggs to implant soon after the male has given birth to the last litter.
What is the mating ritual of a seahorse?
“Their mating ritual is quite beautiful,” said Sarah Foster, a research biologist at McGill University in Montreal who is involved in Project Seahorse. Scientists think the courtship behavior is designed to synchronize the movements of the two animals so that the male can receive the eggs when the female is ready to deposit them.
