Phytoplankton cultures of Chlorella sp., Tetraselmis sp. and Isochrysis galbana were used alone as feed to rear separate batches of newly caught milkfish (Chanos chanos) fry (about 21 days old). Ultrastructural studies of fry hepatocytes and pancreatic acinar cells indicated that they cannot directly utilize Chlorella, which has a rigid cell wall. The fry can directly utilize Tetraselmis and Isochrysis, but neither is nutritionally adequate for growth and survival if used as the only feed. Tetraselmis is nutritionally inferior to Isochrysis.

Salayo, Nerissa D. (International Association of Aquaculture Economics and Management (IAAEM), 2006)Uncertainties and lack of information on milkfish product prices, along with production-related problems with inputs, generally constrain efficient resource use in milkfish grow-out operations. Milkfish growers complain ...
The effect of tank color and rotifer density on rotifer ingestion, growth and survival of milkfish (Chanos chanos) larvae Duray, Marietta N. (San Carlos Publications, University of San Carlos, 1995)The effect of tank color on rotifer ingestion, early growth and survival of milkfish larvae was assessed. The larvae were stocked at 30/L in 200-L fiberglass tanks coated black or unpainted (tan). Larvae were fed rotifers ...
Qualitative analysis of the contents of the anterior portion of the oesophagus from adult milkfish, Chanos chanos, captured in Pandan Bay from 10 May-June 1975 Villaluz, Antonio C.; Tiro, Leonardo B.; Ver, Leo M.; Vanstone, William E. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1976)Qualitative analysis of food items in the anterior spiral portion of the oesophagus suggests that adult milkfish feed on both benthic and planktonic materials.
