Antibiotics, chemicals, and probiotics are often used in aquaculture activities to successfully culture species. The purpose of this study was to compare the effectiveness of the application of erythromycin, elbayou, and Rica-1 probiotic in the rearing of S. paramamosain mud crab larvae development to the crablet stage. The newly hatched healthy larvae zoea-1 were cultured in nine fiber tanks with a volume of 200 L each at the density of 80 ind. L⁻¹. The three treatments tested consisted of A) Erythromycin; B) Elbayou; and C) Rica-1 probiotic with a dose of 15 mg L⁻¹ each. Each treatment with three replications. Several parameters were monitored including the larvae density, larvae stage development, and water quality parameters such as ammonia, nitrite, total organic matter (TOM), Vibrio sp, and total bacteria population. At the Day of Rearing (DOR)-15, the larvae developed into zoea-5 with a density of 15.3 ± 2.1 ind. L⁻¹ (A); 16.3 ± 2.5 ind. L⁻¹ (B), and 7.3 ± 1.5 ind. L⁻¹ (C). At DOR-19, some larvae zoea-5 successfully metamorphosed into the megalopa stages. The crablet-D15 production in erythromycin treatment was 141.2 ± 34.1 ind. tank⁻¹, significantly different (P < 0.05) from the Elbayou treatment production of 70.0 ± 3.74 ind. tank⁻¹. However, there was no significant crablet production from the RICA-1 probiotic treatment due to megalopa's death as a consequence of Vibrio harveyi infection. As a result, the erythromycin application of 15 mg L⁻¹ was the most effective for increasing crablet production in rearing mud crab larvae.

抗生素、化学品和益生菌通常用于水产养殖活动以成功养殖物种。本研究的目的是比较红霉素、elbayou 和 Rica-1 益生菌在将S. paramamosain 泥蟹幼虫发育到小蟹阶段的饲养 效果。新孵化的健康幼虫 zoea-1 在 9 个容量为 200 L 的纤维池中以 80 ind 的密度进行培养。L ^-1。测试的三种处理包括 A) 红霉素；B) 埃尔巴尤；和 C) Rica-1 益生菌，剂量为 15 mg L ^-1每个。每个处理重复 3 次。几个参数进行监测包括幼虫密度，幼虫阶段的发展，和水的质量的参数，例如氨，亚硝酸盐，总有机物质（TOM）， 弧菌 属， 和总细菌群体。在饲养日 (DOR)-15，幼虫发育成 zoea-5，密度为 15.3 ± 2.1 ind。L ^-1 (A); 16.3 ± 2.5 英寸 L ^-1 (B) 和 7.3 ± 1.5 ind。L ^-1 (C)。在 DOR-19，一些幼虫 zoea-5 成功地变形成了巨蜥阶段。红霉素处理中的小蟹-D15 产量为 141.2 ± 34.1 ind。tank ^-1，与 Elbayou 处理产量 70.0 ± 3.74 ind 显着不同（P < 0.05）。坦克^-1。然而，由于哈维伊弧菌 感染导致巨蟹死亡，RICA-1 益生菌处理没有产生显着的小蟹产量 。结果，15mg L ^-1的红霉素施用对于在饲养泥蟹幼虫中增加小蟹产量最有效。
