珍珠贝卵的早期发育非常关键，因此卵需要合适的基质来沉降以完成其变态。在这个阶段，附着体的足丝很脆弱，如果有一些干扰（例如，压力），很容易破裂。水的运动，因此鱼卵很容易落到底层，底层可能含有各种污垢，导致鱼卵死亡。在珍珠贝养殖中，卵收集器很重要。本研究的目的是研究不同捕集器材料对沉降卵数量的影响，以揭示最佳捕集器材料和捕集器对卵的耐受力。这项研究是在努沙登加拉省松巴哇岛的 PT Autore Pearl Culture 进行的。本研究中使用的材料是不同物质的收集器，即石棉 (A)、竹子 (B)、聚乙烯和屋顶陶瓷 (D) 物质。使用的方法是实验室实验，采用完全随机设计，进行 4 次处理和 3 次重复。采集的数据包括卵沉降数量、耐久性测试和水质。数据通过方差分析 (ANOVA) 进行测试，并通过邓肯重复区域测试进一步测试。对水质进行了描述性分析。结果表明，不同捕收剂材料对沉降卵数有显着性差异（p<0.01）。聚乙烯达到的最佳沉降[106±3.61 ind.] (dm2)-1] 其次是竹子 [40±3.61 ind. (dm2)-1] (dm2)-1]，石棉 [16±2.52 ind。 (dm2)-1] 和屋顶陶瓷 [15±3.61 ind. (dm2)-1] 和屋顶陶瓷 [15±3.61 ind。 (dm2)-1]。耐久性测试表明，处理B（10.23%）达到了最低的卵从收集器上脱落的百分比，其次是C（11.12%）、D（46.95%）和A（50.60%）。研究期间的水质适合珍珠贝贝的生活和生长。
Early stage development of pearl oyster spat was very critical, hence spat required suitable substrates for their settlement to complete their metamorphosis. In this stage, byssus for the attachment is vulnerable and easy to break if there are some disturbance e.g. water movement, hence spat easily falling onto the bottom layer which may have various dirt materials leading to the dead of the spat. In the pearl oyster culture spat collector is important. The aim of this study is to study the effect of different collector materials to the number of spat settled, to reveal the best collector materials and the endurance of spat at the collector. This study was conducted in PT Autore Pearl Culture, at Sumbawa island, Nusa Tenggara Province. Materials used in this research were collectors of different substance i.e. asbestos (A), bamboo (B), polyethylene and roof ceramic (D) substance. The method used was laboratories experiment with Completely Random Design by 4 treatments and 3 replications. Data taken were the number of spat settlement, endurance test, and water quality. Data tested with Analysis of Variance (ANOVA) and further tested with Duncan Duplicate Regional test. Water quality was analyzed descriptively. The results showed that different collector materials performed a high significantly difference (p<0.01) to the number of spat settled. The best settlement reached by polyethylene [106±3.61 ind. (dm2)-1] followed by bamboo [40±3.61 ind. (dm2)-1], asbestos [16±2.52 ind. (dm2)-1] and roof ceramic [15±3.61 ind. (dm2)-1]. The endurance test indicated that percentage of lowest detached of spat from collector reached by treatment B (10.23%), followed by C (11.12%), D (46.95%) and A (50.60%). Water qualities during study were appropriate for the life and growth of pearl oyster spat.
