Abstract

The invention aims to provide a method for breeding stingray fry, which comprises the following steps: A, water quality management: taking water from a deep well to fill a water storage pond, then introducing air into the water storage pond to supplement oxygen for more than 8 hours, and meanwhile, controlling the water temperature of the water storage pond to be 28-30 DEG C; adding sodium chloride according to 0.05-0.2% of the weight of water in the water storage pond, and uniformly mixing to stabilize the water quality; b, culture environment management: pumping water from the water storage pond, further oxygenating, purifying and sterilizing, feeding into a culture pond, putting the fry into the culture pond for culture, and oxygenating in the culture pond, wherein the culture pond is located in a culture room, and the room temperature is controlled to be 28-30 DEG C; c, feeding management: starting to feed the newly born fry after waiting for 3-5 days, setting the feed as fine shrimp, and feeding once in the morning and once in the evening every day; after half a month, feeding with shrimps in the morning and feeding with loaches in the evening. The method is low in breeding cost, low in fry death rate and good in application prospect.

Description

technical field [0001] The invention relates to the technical field of fish farming equipment, in particular to a method for cultivating stingray fry. Background technique [0002] Stingrays, also known as devil rays, are the same kind of sharks that appeared in the Jurassic period of the Mesozoic (about 180 million years to 140 million years ago). They have the habit of hiding in the sand on the seabed. The stingray has a flat body, slightly round or diamond-shaped, cartilage without scales, well-developed pectoral fins that spread wings like a butterfly, and a whip-shaped tail with poisonous spines. Live under the sea. There are many types, the common ones are sharp-billed ray, red ray, eagle ray and so on. [0003] Stingrays are difficult to breed, and they will die if you don’t pay attention, especially their fry, which are more stringent in terms of breeding equipment, environmental requirements, and breeding methods. The breeding of fry is one of the key difficultie...
