A study on the feeding of shrimp larvae of Macrobrachium nipponense on algae in vitro

Experiments were carried out for the propagation and rearing of Macrobrachium nipponense its feeding on algae, with aim determining density, survival, growth larvae in vitro. Hatched zoae reared at a density 50 zoea/L algae mixture: Chlorella vulgaris, Scenedesmus sp., Pediastrium Microctinium Navicula Ulothrix Cyclotella Daitoma sp. three concentrations 0.5=A, 1.0=B, 1.5=C x 10⁵ cell/ml, survival % rates zoea 45.00±5.00, 53.33±7.64, 50.00±5.00 respectively. Then, densities: 25=A, 50=B, 75=C tested by them best concentration 1.0×10⁵ cell/ml 10 days, result being 50.00±5.00, 51.67±7.64, 31.67±7.64, After that, stage post-larvae (50=A,100=B, 150=C) Pl/pond fed 1.0 mixture 28 which resulted 48.33±7.64, 40.00±5.00, 33.33±7.64, this stage, weight was 50.67±2.08, 50.00±2.00, 40.33±2.52mg The results analysis different densities found significant differences (P < 0.05) between C both A B, there no > them. There (p selected algae. Also, rate when (B).
