1. The seawater hard clam Meretrix lusoria is an important aquaculture species in Asian countries. Its diet comprises mainly microalgae species from the culture ponds. Because of the benefits of n-3 highly unsaturated fatty acids, such as eicosapentaenoic acid and docosahexaenoic acid, toward cardiovascular disease, many cultured aquatic animals are enriched with these fatty acids through dietary treatments to increase their nutritional values. This practice can be applied to bivalve culture using microalgae as the dietary fatty acid provider. (25%)

3. Ventilation refers to the movement of water over the gill. The fish respiratory system moves water over the gills by the coordinated expansion and contraction of the buccal and opercular cavities. It is difficult to measure this, as the result, there is an indirect method one can count visually the opercular beat. (25%)

4. In fish the branchial heart is contained within a pericardial sac, consists of four chambers, the sinus venosus, the atrium, the ventricle, and either the bulbus arteriosus (in teleosts) or the conus arteriosus (in cyclostomes and elasmobranchs). (25%)
