how many young does a oar fish produce and does it live alone or in group's?

Answer 1

Regalecus glesne is an elusive fish. Since they live in waters from 20 meters to 200 meters the information on this fish is sketchy at best. They have never been seen in groups and are though to be loaners.

Spawning is said to occur between July and December and larvae are encountered near the surface

The spawning of oarfish has not been observed, and little is known of its spawning habits or seasons. The ovaries of a dying female, about 9.8 ft (3 m) in length, that was cast ashore on the west coast of Florida weighed 3.1 lb (1.4 kg) and contained approximately 140,000 unspawned eggs, some of which were ovulated. The female was observed in March, along with other dead male fish, presumably following a spawning occurrence. Oarfish eggs are pelagic and have been identified in plankton collections in the Mediterranean Sea and the waters off New Zealand. Eggs are large, 0.08–0.16 in (2–4 mm) in diameter, with pink to red chorions, and they contain numerous scattered oil droplets. Researchers report that eggs can take up to three weeks to incubate and that the emerging larva is highly developed at hatching, with a functional mouth and gut, a pigmented eye, and long dorsal and pelvic fin rays. Young oarfish resemble adults in most details and have been captured on research cruises in the Atlantic and Pacific Oceans. Vital rates, feeding habits, and predators of larvae are largely unknown.

Answer 2

I used to reproduce those fish!! i discover the boys commonly are longer, and the girls are fatter. however the regularly occurring length is approximately 5 cm or so. i found out from breeding that they do precisely like the corporate, yet be certain in case you have one lady to only have one male as in case you have better than one male it is going to likely be too plenty stress for the female and she or he will die. frequently the ratio i bypass via is two:a million. So 2 women for each a million male. those fish are quite jollly and get alongside with the different fish...as long because of the fact the different fish dosnt harass them...So i could have approximately 3 at the same time. wish i've got helped!!

Answer 3

Apparently it's a solitary animal and doesn't live in groups. Mating and breeding information isn't available on these fish and has not been observed.
