本研究旨在通过人工繁育技术来重新移居珠母贝属Pteria sterna。对养殖的658个幼年珠母贝进行了四种不同繁育的试验:保护的底质、未保护的底质、自然底质以及人工底质。试验也检验了另外两个生物生态因素的影响:深度和样品大小。我们评估了样品的存活率、固着速率和强度、以及原地生长。根据获得的最好结果,我们试图确定用于进一步大规模重新移居行动的最优深度、大小和播种材料。个体存活的一个非常重要的因素是保护;所有放养到未保护的底质上的牡蛎在几天之内都死了。自然底质提高了个体的固着速率、强度和生长,而人工底质没有。就存活率、固着速率、强度和生长而言,9m的深度和中小尺度结果最好。
The aim of this study was to re-migrate Pteria sterna through artificial breeding techniques. Four different breeding tests were conducted on 658 young pearl oysters bred: protected, unprotected, natural and artificial substrates. The experiment also examined the effects of two other bioecological factors: depth and sample size. We evaluated the viability, fixation rate and strength of the samples as well as in-situ growth. Based on the best results obtained, we sought to determine the optimal depth, size and sowing material for further mass reintegration. A very important factor in the survival of an individual is protection; all the oysters that are stocked on the unprotected substrate die within a few days. Natural substrate enhances individual fixation rate, strength, and growth without artificial substrate. In terms of viability, anchorage rate, strength and growth, the 9m depth and mesoscale results were best.
