Embodiment Construction

[0010] First use 150kg of fermented decomposed pig manure, 50kg of chicken manure and 0.5kg of biological algae seedlings (containing bacillus, amino acids and various trace elements) to spray the base fertilizer on each pond, and then use fermented manure per mu every 5 days Sprinkle 40kg of pig manure and chicken manure, the ratio of pig manure and chicken manure is 3:1, that is, 30kg of pig manure and 10kg of chicken manure; at the same time, once a week, the biological algae fungus is used for each mu of pool, and the dosage is 0.5kg / mu. Due to the long-lasting fertility of chicken manure, phytoplankton is first cultivated, and the bio-algae bacteria contain bacteria and various nutrients, which can promote the growth of phytoplankton in large quantities. Phytoplankton is the food of zooplankton, and the growth of phytoplankton promotes a large number of zooplankton Reproduction and growth, at the same time, pig manure provides zooplankton with more nutrients for their rapi...

Abstract

The invention relates to a method for culturing natural bait for fry, which comprises the following steps of: firstly, splashing 150 kg of fermented pig manure, 50 kg of chicken manure and 0.5 kg of biological alga-culturing seedlings into each mu of a pond; then splashing 30 kg of fermented pig manure and 10 kg of chicken manure once every five days; and splashing 0.5 kg of biological alga-culturing seedlings into each mu of the pond once a week. The method can quickly culture a great deal of phytoplankton and zooplankton to provide the bait for the growth of the fry.

Description

Technical field: [0001] The invention belongs to the field of aquatic product cultivation, in particular to a method for cultivating natural bait for fry. Background technique: [0002] In the breeding process of aquatic products such as fish, the usual practice is to add artificial feeding bait, thereby ignoring the natural bait existing in the pond. The phytoplankton and zooplankton existing in the pond are the natural bait of fish, which can promote the growth of fry. of rapid growth. However, for large-scale fish farming, naturally growing zooplankton and phytoplankton obviously cannot meet the needs of fry farming. Cultivating natural phytoplankton and zooplankton has become a problem that farmers need to solve urgently. Invention content: [0003] The purpose of the invention is to provide a method for quickly cultivating natural bait for fry. [0004] The present invention realizes the purpose of the invention through the following steps: [0005] a. Sprinkle the...
