Preparation method and feeding method of mixed feed for sea-bone jellyfishes

Abstract

The invention relates to a preparation method of a mixed feed for sea-bone jellyfishes. The preparation method comprises the following steps that step 1, prawns, decapterus maruadsi, polyspring fishes and brine shrimp shelled eggs are prepared, the prawns are decapitated, tailed and diced, decapterus maruadsi and polyspring fishes are decapitated, tailed, eviscerated, boned, shelled and diced, and the mass ratio of the treated prawns to the treated decapterus maruadsi to the treated polyspring fishes to the treated brine shrimp shelled eggs is 2 to 1 to 1 to 1; step 2, the proportioned mixed feed is manually and uniformly stirred with a glass rod, then the mixed feed is put into a stirrer, stirring is carried out with seawater until the mixed feed is pasty, suction test is carried out on the pasty mixed feed by using a plain-end rubber head suction tube with the inner diameter of 4-5 mm, and it is considered that the stirring is qualified when the suction is normal; and step 3, the mixed feed stirred in the step 2 is put into a corresponding freezing box mold, and freezing and storing are carried out until the mixed feed is agglomerated to complete the preparation of the mixed feed. The preparation method is simple, feeding is convenient, a water body is not prone to being polluted, and the growth of the jellyfishes is facilitated.

Description

technical field [0001] The invention relates to the preparation of marine animal feed, in particular to a preparation method of mixed feed for sea thorn jellyfish and a feeding method thereof. Background technique [0002] Jellyfish are creatures that existed 650 million years ago and come in many varieties and shapes. Commonly found in the oceans of various places, it has been widely studied because it can be used as food, has medicinal value, and can also be used as an indicator of ocean currents. Among the jellyfish, the jellyfish class creatures are exhibited by major aquariums because of their large size and ornamental value, and gradually enter the family, becoming another breeding species for aquarium enthusiasts. [0003] Whether it is aquarium breeding or individual breeding in the family, the problem of bait has always been troubled. At present, most of the baits fed by sea thorn jellyfish are artemia nauplii and moon jellyfish. When feeding Artemia nauplii, sin...

Problems solved by technology

[0005] In order to overcome the above-mentioned deficiencies, the purpose of the present invention is to provide a preparation method and a feeding method thereof for sea thorn jellyfish mixed feed to the art, so that it can solve the problem that the existing sea thorn jellyfish bait is difficult to be fed by jellyfish. Sufficient feeding will easily pollute the aquaculture water, cause a large burden on the filter equipment, and easily breed and grow miscellaneous polyps, which is not conducive to jellyfish breeding. In addition, it is usually difficult to freeze the bait for use after storage, and the amount of bait feeding should not be controlled, which is easy to generate waste technical issues
