Tiram juvenil dari spesies Crassostrea iredalei diternak dalam dua eksperimen yang berbeza iaitu Eksperimen I; Kesan sumber fitoplankton berbeza terhadap tumbesaran dan kemandirian tiram juvenil Crassostrea iredalei. Eksperimen II; Kesan sistem ternakan berbeza terhadap tumbesaran dan kemandirian tiram juvenil Crassostrea iredalei. Dalam Eskperimen I tiram juvenil dibekalkan dengan sumber fitoplankton yang berbeza, iaitu fitoplankton liar dan fitoplankton kultur. Pada akhir kajian iaitu selepas 45 minggu penternakan menggunakan sistem pengalir atasan (upwellers) kemandirian tiram yang dibekalkan dengan fitoplankton kultur (32.33 ± 4.11 %) adalah lebih rendah berbanding fitoplankton liar (55.46 ± 4.25 %). Tumbesaran yang dicatatkan oleh tiram juvenil di dalam kedua-dua fitoplankton juga positif namun pada akhir kajian pertumbuhan tiram juvenil yang dibekalkan dengan fitoplankton kultur dilihat lebih tinggi berbanding fitoplankton liar. Juvenile oysters of the species Crassostrea iredalei were cultured in two different experiments namely Experiment I; Effects of different sources of diet on the growth and the survival of the juvenile oysters Crassostrea iredalei. Experiment II; Effects of different culture systems on the growth and survival of the juvenile oysters Crassostrea iredalei. In experiment I, the juvenile oysters were supplied with different sources of phytoplankton (wild phytoplankton and cultured phytoplankton) where the juvenile oysters were cultured using upwelling system for 45 weeks. The survival of the juvenile oysters supplied by cultured phytoplankton (32.33 ± 4.11 %) is lower compared to wild phytoplankton sources (55.46 ± 4.25 %). Juvenile oyster fed with both phytoplankton sources showed a positive growth but towards the end of the study cultured phytoplankton show higher growth compared wild phytoplankton.
