Intensive research on the effectiveness of chemoattractants has been widely explored to improve the feed qualities in expanding crustacean farming. Taste preferences in slipper lobster remained unknown despite their significant contribution to the lobster fisheries. Chemoattractants allow better performance in aquaculture species by increasing food attractiveness and palatability. Amino acids (AA) have been leading in previous research on crustacean feeding behavior. Given that slipper lobster possesses chemoreceptors to detect and orient towards food, this study investigated an approach to identify the AA with the most potent chemoattractant in eliciting a response from slipper lobster. Behavioral assays were performed to evaluate the responses of slipper lobster (carapace length, 52.34 ± 1.52 mm) on 15 crystalline AA and three derivatives of AA (DAA) at three concentrations between 10 and 10 M as test substances (TS). sp. extract was used as a positive control and clean filtered seawater as a negative control. The behavioral responses of 14 were evaluated based on their antennular flicking rate, third maxillipeds activity, and substrate probing by the pereiopods. responded to the solutions of single AA down to a concentration of 10 M, excluding histidine and serine. The behavioral activity displayed by increased with the TS concentrations. L-glutamic acid monosodium salt monohydrate, betaine, and glycine solutions elicited the most behavioral responses, whereas histidine exhibited the lowest behavioral responses. Conclusively, L-glutamic acid monosodium salt monohydrate, betaine, and glycine can be potential chemoattractants for .
人们广泛研究了趋化剂的有效性，以期改善对虾养殖中的饲料质量。尽管滑齿龙对龙虾渔业有重要贡献，但它们的味觉偏好仍不清楚。趋化剂可以通过增加食物的吸引力和适口性来提高水产养殖物种的性能。在甲壳类动物摄食行为的研究中，氨基酸（AA）一直处于领先地位。鉴于滑齿龙具有检测和定向食物的化学感受器，本研究旨在确定最有效的 AA 作为趋化剂，以引起滑齿龙的反应。行为测定用于评估 15 种晶体 AA 和 3 种 AA 衍生物（DAA）在 10 到 10 M 三个浓度下对 （甲壳长 52.34 ± 1.52 mm）的反应，作为测试物质（TS）。sp. 提取物用作阳性对照，清洁过滤海水用作阴性对照。根据触角摆动率、第三颚足活动和附肢对基质的探测，评估 14 种 的行为反应。 对浓度低至 10 M 的单一 AA 溶液有反应，组氨酸和丝氨酸除外。 的行为活性随 TS 浓度的增加而增加。L-谷氨酸单钠盐一水合物、甜菜碱和甘氨酸溶液引起的行为反应最强，而组氨酸则引起的行为反应最弱。总之，L-谷氨酸单钠盐一水合物、甜菜碱和甘氨酸可能是 的潜在趋化剂。
