Marine biological productivity and energy transformation can be estimated through a ratio which transforms solar energy into organic energy in marine organism. Oscillation frequency of solar energy source in Vietnam is 1.243 Kcal/km2/year. This kind of energy transforms into primary productivity and the total primary energy is estimated from 210.1013 to 330.1013 Kcal/year. Total production of fish and other seafood is estimated from 3,1 to 4,2 million tons. Therefore, energy transformation productivity in solar energy - botany channel, and animal - botany channel are obtained from 0.17% to 0.27%, 0.062% to 0.075%, respectively.
