الهدف- Objectives

The project directly addressed the vacuum in health related aspects of marine fish consumption in Lebanon and Eastern Mediterranean countries. It evaluated the protein, lipid and nutritive value of a carnivorous fish and a hebivorous fish of the eastern Mediterranean and studied sesonal variations of the beneficial omega-3 fatty acids.

ألانجازات المحققة Achievements -

The research was completed successfully and the information was published in international journals. Two papers have already been accepted for publication and a third is being written.

آفاق البحث Perspectives -

The information can be used to decide on the most beneficial fish to eat depend on season and the data can be used to solicit further funding.

موجز عن نتائج البحث Abstract -

Results of the study showed that the protein and lipid content of the two fish varied dramatically with the seasons. In some months, it is more healthy to consume Diplodus sargus while in others it is healthier to consume siganus rivulatus. However, if averaged over the whole year, siganus is a healthier fish to consume. Furthermore, rabbitfish generally had less moisture, better filet yield, slightly higher protein proportion and frequently more lipid than white sea-bream. Both fish are similarly priced on the Lebanese market and have regular demand. Consequently, rabbitfish with eight percent more yield on average is better value for the money. The nutritive value of the fish varied with species and season. Furthermore, although fatty fish would supply more omega-3 fatty acids, low fat fish such as the species studied in present paper might be more recommendable since fatty fish might also be high in PAH and polychlorinated organic substances that tend to be lipid soluble and are toxic. These concerns could be mitigated if fish were aquacultured in clean water and offered a diet with appropriate levels of omega-3 HUFA.
