Effect of different stocking densities on survival and growth of sugpo (Penaeus monodon Fabricius) in a milkfish-rearing pond
Primavera, Jurgenne ; ; (STII-DOST, 1976)
; ; (STII-DOST, 1976)
Employing a direct stocking monoculture method, postlarval P. monodon were stocked in 8 compartments of a shallow milkfish rearing pond at densities of 1, 2, 3 and 4/sq m with replicates. Feeding was exclusively natural ...
