Penaeus vannamei larval stage feed and method for preparing same

Abstract

Provided are Penaeus vannamei larval stage feed and a method for preparing the same.The feed comprises 30-35 parts of white fishmeal, 2-5 parts of whey powder, 5-10 parts of Artemia dry powder, 2-5 parts of bloodworm powder, 2-5 parts of earthworm powder, 2-5 parts of wheat gluten power, 5-10 parts of Sargassum thunbergii powder, 2-5 parts of sea lettuce powder, 5-10 parts of Spirulina platensis powder, 5-10 parts of Haematococcus pluvialis powder, 2-5 parts of chlorella powder, 2-5 parts of Cylindrotheca powder, 2-5 parts of Schizochytrium powder, 5-10 parts of Schizochytrium oil, 2-5 parts of chlorella oil, 0.002-0.005 part of photosynthetic bacteria, 0.002-0.005 part of Bacillus subtilis, and 0.01-0.05 part of compound multi-vitamin mineral.The plant components and the animal components that are added meet the feeding habits and nutrition needs of Penaeus vannamei larvae so that the larvae can smoothly develops by metamorphosis and quickly grow, and survival rate is increased.

Description

Technical field [0001] The invention belongs to the technical field of aquatic feeds, and specifically relates to a juvenile feed for Penaeus vannamei and a preparation method thereof. Background technique [0002] Penaeus vannamei is one of the world’s highest aquaculture production of shrimp. Since my country introduced it from the Pacific coast of South America, especially in 1992, it broke through the nursery barrier, and it was quickly promoted along the coast of my country and became one of the main cultured shrimps in my country. Provide high-quality protein foods for fishermen to increase production and income and enrich consumers' tables. [0003] Penaeus vannamei has high nutritional value, delicious meat, and a meat yield of 67%. It is a rare breeding species. Compared with other shrimp species, Penaeus vannamei has mixed feeding habits, strong disease resistance, fast growth, high breeding success rate, and low requirements for protein content in feed, all of which brin...

Problems solved by technology

[0004] However, although the nutritional and physiological research on the larval stage of Penaeus vannamei has made progress, it has not been reflected in the research and development of feed in time. The feed for the larval stage of Penaeus vannamei has not yet been developed, and some breeding companies still use natural food as bait , cultivated by means of fertilizer and water

However, this method is likely to cause abnormal development and unsatisfactory growth of prawn larvae, and even cause deformity or death of larvae at this stage.
