Abstract

The invention discloses a bait formula for enhancing nutrition of meretrix lamarckii at a planktonic larva phase. The bait formula comprises the following raw materials in parts by weight: 3-7 parts of a chlorella mother liquid, 0.5-0.8 part of a isochrysis galbana parke mother liquid, 0.6-0.9 part of a chaetoceros mulleri mother liquid, 0.05-0.6 part of a platymonas subcordiformis mother liquid and 0.02-0.06 part of a rhodotorula benthica mother liquid. The bait formula for enhancing nutrition of meretrix lamarckii at the planktonic larva phase, which is disclosed by the invention, has comprehensive and sufficient nutrition, is good in palatability, excellent in food calling and intake effect, capable of meeting requirements of enhanced nutrition and high-metamorphosis survival rates at the larva phase, improving the immunity and the stress resistance of zooplankton, improving disease and insect resistance of the zooplankton and purifying water, and has rich bacterial with high activity and metabolite with great gain, and development by metamorphosis of planktonic larvae can be accelerated.
