Problems solved by technology

The demand for its fry has also increased greatly. Like all seawater fish, the early larvae of the pomfret are small in diameter and have stricter requirements for open bait. At present, the best and practical bait organisms are rotifers and copepods , but the large-scale production of rotifers requires certain technologies and sites, and the cultivation of algae for rotifers requires a large site and water body for production, so the cost of seed cultivation is relatively high, and the price of seed is also at a high level for a long time

Embodiment 1

[0027] Present embodiment provides a kind of cultivation method of oval pomfret seed, it comprises the following steps:

[0028] (1) Pond cleaning and disinfection.

[0029] The specific realization is that the pond is cleaned, exposed to the sun for 2 days, water inflow is 50cm, the whole pond is sprinkled with quicklime, the amount of quicklime is 80kg / mu, and the waterwheel type aerator is started to stir the pool water to make the disinfection even.

[0030] (2) into the hydroponic algae.

[0031] The specific implementation is to continue to add sand-filtered seawater to a depth of 2m after 3 days, select a sunny day at 10-11 a.m. to inoculate the algae, and sprinkle the algae auxin, and start the waterwheel type aerator to stir the pool water to promote the growth of algae.

[0032] (3) Inoculate rotifers and put prawn seedlings.

[0033] The specific realization is that when the water color of the pond is getting thicker, that is, when the color of the translucent alg...

Embodiment 2

[0047] Present embodiment provides a kind of cultivation method of oval pomfret seed, it comprises the following steps:

[0048] (1) Pond cleaning and disinfection.

Abstract

The invention discloses a method for cultivating egg-shaped pomfret seedlings, which comprises the following steps: (1) pond cleaning and disinfection; (2) feeding algae into water; (3) inoculating rotifers and releasing prawn seedlings; 4) hatching of fertilized eggs; (5) setting up nursery cages, wherein the newly hatched pomfret larvae cannot pass out of the nursery cages, and algae and rotifers in the pond can enter and exit the nursery cages; (6) cages Nursery: Newly hatched pomfret larvae feed on rotifers in nursery cages, prawns in ponds feed on rotifers, rotifers eat algae, and the entire pond forms a small ecological balance system; (7) Replace nursery cages: according to The body length of oval pomfret larvae gradually replaces the cage with large mesh; (8) Harvest seedlings. The method for cultivating egg-shaped pomfret seedlings of the present invention utilizes the current pond for cultivating prawns to cultivate oval-shaped pomfret carp seedlings while cultivating prawns, fully utilizes breeding sites, facilities and labor, and effectively reduces breeding costs.

Description

technical field [0001] The invention relates to the technical field of pompano seedling cultivation, in particular to a method for cultivating egg-shaped pomfret seedlings. Background technique [0002] Oval Pomfret ( Trachinotus ovatus ) commonly known as golden pomfret, yellow wax pomfret, red three, etc., belonging to Perciformes, Perciformes, Trevalidae, Pomfret subfamily, Pompano genus ( Trachinotus ), widely distributed in tropical and temperate waters of the Pacific, Atlantic and Indian Oceans. The fish is large in size, fast in growth, simple in food habits, tender and delicious in meat quality, and is widely loved by farmers and consumers. With breakthroughs in its breeding technology, artificial compound feed can be used throughout the breeding process, and the export processing market is large. In recent years, the aquaculture industry of oval pomfret has developed rapidly in my country, and has become one of the main seawater fish cultured in cages in souther...
