Differences and similarities between spiny lobster’ sexes diet could result from multifactorial environmental influence. We evaluated the trophic spectrum for Panulirus argus, estimated lobster’s selectivity, and corroborated the hypothesis that lobster’ sexes diet is similar between subzones with different benthic community in two fishing subzones of the gulf of Batabano, Cuba. Stomach contents of 52 lobsters from Diego Pérez (DP), and 68 from Aguardiente (AA), were analyzed. Frequency of occurrence (FO), gravimetric (G), and relative importance (IIR) indices were calculated for each food category. Ellenberg Similarity (ISe), Morisita, and Ivlev Selectivity (E) indices were also applied. Different diet descriptors were also related to benthic community attributes also used to compare between subzones and sexes. Trophic spectrum for P. argus consisted of gastropods, bivalves, polyplacophores, sea urchins, stomatopods, brachyurans, anomurans, polychaetes, ophiuroids, sponges, foraminifera, hydrozoans, fish, and plant matter. The E index showed a P. argus positive selectivity for gastropods Costoanachis sp., Diodora sp., Lucapina sp., Rissoina sp., Fasciolaria tulipa, and Gibberula fluctuata, the bivalves Arcopsis sp., Barbatia domingensis, Antillipecten antillarum, and Codakia orbicularis, and crustaceans of the Order Stomatopoda. Selectivity was highest but negative for Pinctada imbricata, Tucetona pectinata, Chione sp., and anomurans. Diet between sexes was similar in DP (ISe = 47.1%) and the same in AA (ISe = 97.6%), both with high trophic level overlap. Lobster’s diet descriptors and the diet for each sex were similar (medium level) between subzones, while the attributes of the benthic community were different. Similarities between diets for each sex were kept despite differences in benthic community-specific composition.

多刺龙虾的两性饮食之间的差异和相似之处可能是多因素环境影响的结果。我们评估了Panulirus argus的营养谱，估计了龙虾的选择性，并证实了古巴巴塔巴诺湾两个捕鱼分区中具有不同底栖生物群落的分区之间龙虾的性别饮食相似的假设。分析了来自 Diego Pérez (DP) 的 52 只龙虾和来自 Aguardiente (AA) 的 68 只龙虾的胃内容物。计算了每种食品类别的发生频率 (FO)、重量 (G) 和相对重要性 (IIR) 指数。还应用了 Ellenberg 相似度 (ISe)、Morisita 和 Ivlev 选择性 (E) 指数。不同的饮食描述也与底栖群落属性有关，这些属性也用于比较亚区和性别。P. argus的营养谱由腹足类、双壳类、多足纲、海胆、口足类、短足类、异鼠类、多毛类、蛇类、海绵类、有孔虫类、水螅类、鱼类和植物组成。E指数显示对腹足动物Costoanachis sp .、Diodora sp .、Lucapina sp .、Rissoina sp .、Fasciolaria tulipa和Gibberula fluctuata、双壳类Arcopsis sp .、Barbatia domingensis、Antillipecten antillarum和Codakia orbicularis具有阳性选择性和口足纲甲壳类动物。Pinctada imbricata的选择性最高，但为阴性，Tucetona pectinata、Chione sp .和anomurans。DP (ISe = 47.1%) 和 AA (ISe = 97.6%) 的两性饮食相似，两者都具有高营养水平重叠。龙虾的饮食描述和每个性别的饮食在分区之间相似（中等水平），而底栖动物群落的属性不同。尽管底栖社区特定组成存在差异，但每种性别的饮食之间的相似性仍然存在。
