40. The Masked Duck

41. Discussion
15 native species of ducks that dwell in Trinidad and 2 species of goose
Of these natural resources, it can be very economic and logical to use the ducks/geese that are available to us and are already adapted to out tropical conditions for commercial use

42. Conclusion
Of the 17 species available to us in Trinidad, some of the ducks should be reared for eggs (The Lesser Scaup) and some others for meat ( The Muscovy) to lower the dependency of importation of broilers and other foreign breeds and meats and start producing locally
