Abstract

The invention relates to the technical field of aquaculture fry breeding, in particular to a special indoor artemia breeding method for seawater fish and shrimp fry breeding. The method specifically comprises the following steps: step 1, indoor artemia breeding; step 2, bait feeding; and step 3, nutrient enrichment. The indoor artemia breeding method is established by optimizing the culture method, the breeding yield is stable, the survival rate is high, in addition, the cultured artemia is subjected to nutrient enrichment through schizochytrium limacinum and nannochloropsis oculata, the nutritive value of artemia is increased, especially the unsaturated fatty acid content is increased, and therefore, high-quality biological bait is provided for aquatic fry breeding; and the method can beapplied to large aquatic fry breeding fields and can also be used for commercial production.

Description

technical field [0001] The invention relates to the technical field of aquaculture seed breeding, in particular to an indoor culture method for Artemia special for raising seawater fish and shrimp seedlings. Background technique [0002] Artemia, also known as Artemia, is a small crustacean distributed worldwide. Due to its high nutritional value and rich content of unsaturated fatty acids, it is beneficial to the growth and development of aquatic animals, improves disease resistance, improves the survival rate of fish and shrimp fry, and becomes a high-quality bait for the aquatic fry industry. In recent years, with the continuous development of seawater famous, special and high-quality cultured species, farmers' demand for high-quality seed has continued to increase, and animal-based biological bait has become one of the important factors affecting the quality of seed. However, due to factors such as biological security and insufficient nutrition, Artemia caught in the wi...
