Pellet feed for parent fish reproduction of clownfish and preparation method thereof

Abstract

The invention relates to pellet feed for parent fish reproduction of clownfish and a preparation method thereof, and belongs to the field of aquatic feed. The pellet feed consists of, by mass percentage, 56% of fish meal, 5% of vital wheat gluten, 8% of seaweed powder, 14% of flour, 2% of yeast, 1% of multi-vitamins, 1% of compound minerals, 0.1% of vitamin C, 0.4% of allicin with 25% content, 2.5% of astaxanthin with 2% content, 1.25% of arochidonic acid oil with 40% content and 8.75% of fish oil. The parent fish of clownfish can be robust in body constitution, strong in vitality, stable in egg laying, large in egg laying amount, orange in egg color and high in hatching survival rate by feeding the pellet feed prepared by the above raw materials to the parent fish of the clownfish.

Description

technical field [0001] The invention belongs to the field of ornamental fish feed, and relates to a granular feed for broodstock breeding of clownfish and a preparation method thereof. Background technique [0002] Clownfish, also known as sea anemone fish, is typically characterized by white lines on its face and looks like a clown. It is a common name for all fishes of the genus Echinopsis and Amphitheater. Clownfish is one of the most popular marine fish for ornamental fish lovers in the world. At present, there are more and more domestic bred clownfish. However, most of the clownfish sold in my country’s seawater fish market are imported wild fish caught abroad. The survival rate is low. The ecological environment has been greatly damaged, and there is an urgent need to increase artificial breeding and solve various key problems in artificial breeding, such as the nutritional problem of fish species. [0003] Tan Qingsong et al. (2016) reported that feed nutrition has an...

Problems solved by technology

However, there is currently a lack of feed specifically for the breeding of clownfish broodstock on the market, and it can only be replaced by other fish feeds. It is difficult to guarantee the stability, egg quantity and hatching survival rate of broodstock

Some farms try to use chilled bait to feed broodstock, but chilled bait has two major disadvantages: 1. The material is a variety of chilled fish, shrimp, shellfish, algae, etc., which have not been specially sterilized and disinfected, and are easy to carry various pathogenic organisms 2. Chilled bait is easy to disperse and release various organic substances in the water body, and long-term feeding will easily cause water quality to deteriorate

Other fish feeds are generally ornamental fish feeds or growth-promoting edible fish feeds. If these feeds are fed for a long time, the parent fish will not have enough nutrition or balance, can not lay eggs stably, and the egg quality is not good, and the intestines and liver are easily damaged. Susceptible to the attack of pathogenic microorganisms, it is easy to die, which brings great losses to the breeding industry
