Feeding ecology of Glaucostegus cf. granulatus was investigated based on the samples collected from the inshore coastal waters of eastern Arabian Sea. Teleost contributed significantly to the diet (46.9%) followed by crustaceans (44.6%). The trophic level was estimated to be 3.9 indicating the species as a secondary consumer. The species is a generalist feeder and have a broader niche as indicated by the values of Levin’s Index (B_N = 0.4) and Shannon–Wiener Index (H′ = 3.2). This is the first comprehensive study on the feeding ecology of this vulnerable species from this region, and suggest they consume a wide variety of prey items.

Glaucostegus 的饲养生态参见。基于从阿拉伯海东部近海沿岸水域收集的样品对颗粒状蝽进行了研究。硬骨鱼对饮食的贡献很大（46.9%），其次是甲壳类动物（44.6%）。营养水平估计为 3.9，表明该物种是次要消费者。如莱文指数 ( B _N  = 0.4) 和香农-维纳指数 ( H ' = 3.2)所示，该物种是多面性饲养者，具有更广泛的生态位。这是对该地区这种脆弱物种的摄食生态的第一次综合研究，并表明它们消耗各种各样的猎物。
