Mass production of Penaeus monodon Fabricius juveniles in earthen nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)Different culture techniques were tried for rearing larvae of Penaeus monodon , in order to obtain preliminary data on stocking density, water management, fertilization versus feeding and effect of different types of ... -
Fishwater and agar as binders in a prawn diet
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)The objectives of the study were to find out the proportion of water to fish fins, skin and bones that would give a good gel and to determine the effect of a combination of fish water and commercial crude agar on the water ... -
Selection and application of a suitable sampling method for quantitative and qualitative evaluation of lab-lab
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Milkfish and prawn pond operation in the Philippines is often associated with lab-lab culture. Lab-lab is a biological complex of blue-green algae, diatoms, bacteria and various animals which form a mat at the bottom of ... -
Effect of feeding rate on the survival and growth of milkfish (Chanos chanos) fry in a controlled environment
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)The optimum daily feed allowance varies with species, age, size, frequency of feeding, culture procedures, quality of feed and water quality. This experiment indicated that with a diet containing 40% protein and 3,450 kcal ... -
