Problems solved by technology

At present, there have been some studies on the requirements of flounder for protein, fat (including essential fatty acids), vitamins, and trace elements, but high-efficiency and high-quality artificial compound feeds have not yet been developed, and most farmers still use sm...

Method used

Flounder fry are taken from Ningde City Jinding Seawater Nursery Farm, and after 15d, the fry of flounder with strong physique and strong appetite are randomly selected as test fish. The average body weight of the test fish was 6.5±1.6g, and the average body length was 9.1±1.2cm. The feeding experiment was carried out in the recirculating aquaculture system of our institute. Each group of feed was set up with 2 replicates, and 80 flounder with similar specifications were selected for each group, and they were separately raised in 4 glass fiber reinforced plastic tanks of 150cm×100cm×70cm. The water for breeding was artificially prepared seawater, and the experiment was carried out from May 17, 2004 to July 19, 2004. The feed was fed in the form of soft pellet feed, and the experimental group and the control group were fed compound feed and small miscellaneous fish respectively. The contents of NH3-N, NO2-N and total phosphorus in the water body of flounder after feeding increased first and ...

Abstract

The invention discloses a high-efficiency and environmentally-friendly compound feed for paralichthys olivaceus and a preparation method thereof. According to a formula, the feed comprises the following components: fish meal, alpha-starch, beer yeast, extruded soybean, soybean lecithin, soybean meal, fish oil, camitine, glycine betaine, choline chloride, calcium biphosphate, enzyme preparation and various vitamins and mineral salts. The preparation method comprises the following steps of: weighing the materials in proportion; uniformly mixing the materials and then crushing the mixture to ensure that 98 percent of the raw materials pass through a test sieve with meshes of 0.25mm; adding the alpha-starch, the carnitine, the enzyme preparation and various vitamins and mineral salts into the obtained product in proportion and uniformly mixing the mixture again; adding the fish oil and water in an amount which is 45 percent of the total weight of each component of the feed for the paralichthys olivaceus according to the formula into the mixture and uniformly stirring the mixture; and pelletizing and molding the mixture with a soft granulator. The compound feed prepared by the method and meeting the growth characteristics of the paralichthys olivaceus has the advantages of improving the feed digestibility, the survival rate and the growth speed of the paralichthys olivaceus, reducing pollution on sea area and protecting marine ecological environment.
