This science project aims to study the effect of different basket materials on the survival rate and growth of oysters (Crassostrea belcheri), which is a popular economic animal in Trang Province because it tastes good and can generate stable income for farmers. Raising oysters in baskets is a popular method, but there is still no clear information on how different basket materials affect the growth and survival rate of oysters. This experiment used 3 types of baskets: plastic baskets, woven wooden baskets, and iron baskets. Forty-five 5-month-old oysters of similar sizes were divided into 5 baskets each. The experiment was repeated 3 times. The average total weight of each basket was approximately 725 grams. The oysters were raised in a natural environment and their growth in terms of length, width, thickness, weight, and survival rate were measured. Water quality, such as temperature, salinity, pH, and TDS were also checked every 2 weeks for 3 months. The results showed that oysters raised in woven wooden baskets had the highest survival and growth rate, followed by those raised in plastic baskets, and those raised in iron baskets had the lowest survival rate. This may be due to the different properties of the materials that affect water flow, plankton adhesion, and sediment accumulation. The results of this research can be applied to select appropriate materials for oyster cultivation to increase the efficiency of cultivation and create sustainable income for farmers in the community.
