IntroductionThis study aimed to evaluate the status, resource use, and challenges of the capture-based hatchery of black tiger shrimp (Penaeus monodon) (BTS).MethodsData was obtained through the investigation of 15 broodstock fishing boats and 60 capture-based BTS broodstock hatcheries. Resource use index (RUI) of the capture-based BTS hatchery, calculated from 1,000 female brooders to produce 15-day-old post-larvae (PL15) (production efficiency of PL15, or PE-PL15), was analysed.ResultsThe results indicated that the fishing boats captured an average of 5,900 brooders.boat-1.year-1, 20,856 kg of by catch.boat-1.year-1, and the PE-PL15 production of 937 million for 1,000 female brooders. In the hatchery stage, the use of larger body weight female brooders had benefits in terms of higher survival rate and better efficiency of labour use, Artemia cyst, and probiotic products, but it reduced the efficiency use of chemicals, pellets, and total tank volume of the hatchery.DiscussionThere is increasing use of domesticated brooder sources, but wild-caught brooders still play an important role in producing low-cost PL15 for traditional shrimp farming systems, accounting for most farmed BTS production. Therefore, the certification of good practices should be implemented to capture-based BTS hatcheries for the reasonable use of this brooder resource to sustain BTS farming in Vietnam.

越南黑虎虾（斑节对虾）捕捞孵化场：资源利用和挑战分析


简介本研究旨在评估黑虎虾（Penaeus monodon）（BTS）捕捞型孵化场的现状、资源利用和挑战。方法通过对 15 艘亲鱼渔船和 60 个捕捞型 BTS 亲鱼孵化场的调查获得数据。 。分析了基于捕获的 BTS 孵化场的资源利用指数 (RUI)，根据 1,000 只雌性育雏鱼生产 15 日龄后期幼体 (PL15) 计算得出（PL15 或 PE-PL15 的生产效率）。 结果结果表明渔船平均捕获 5,900 只育雏鱼。boat-1.year-1，catch.boat-1.year-1 捕获量为 20,856 公斤，1,000 只雌性育雏鱼的 PE-PL15 产量为 9.37 亿只。在孵化阶段，使用较大体重的雌性育雏器具有更高的成活率和更好的劳动力使用效率、丰年虫包囊和益生菌产品的优点，但降低了化学品、颗粒和总池容积的使用效率讨论 驯养育雏鱼来源的使用越来越多，但野生捕捞育雏鱼在传统虾类养殖系统生产低成本 PL15 方面仍然发挥着重要作用，占养殖 BTS 产量的大部分。因此，应对捕捞型 BTS 孵化场实施良好做法认证，以合理利用这种育雏资源来维持越南的 BTS 养殖。
