Diet composition of nine commercially exploited fishery resources which contributes 55–60% of the total fish landings in the northwest coast of India were analyzed in this study. Gut content analysis of the selected fish groups has shown significant variations in the prey composition and predator preference on a prey item. The diet matrix revealed Acetes sp. (32.74%) as a key and common shared prey item, followed by mesopelagic fishes (30.51%), other shrimps (11.00%), digested material (7.42%), crabs (4.03%) and cephalopods (2.77%), etc. In this study, Acetes sp was considered as a proxy for the non-penaeid prawns due to its significant contribution (92%) to the total non-penaeid landings. Targeted exploitation of Acetes sp. has intensified recently (from 0.44 lakh t in 2004 to 1.40 lakh t in 2018) with an average annual growth rate of 11.2% due to the demand from fish meal plants. By considering its ecological and fishery importance, Acetes sp. should be considered as keystone species in the ecosystem. The Schaefer surplus production model was used to calculate the Biological Reference Points (BRPs) and model parameters MSY, FMSY, r, EMSY, and K. The model fit was fair (R² = 0.630) and significantly positive correlation was observed between CPUE_observed and CPUE_model. The estimated optimum exploitation limits (p < 0.05) for the fishery were Maximum Sustainable Yield (MSY) as 1.20 lakh t and fishing effort required to harvest MSY (EMSY) as 51.30 lakh fishing hours. However, the recent exploitation yield and fishing effort are beyond the optimum exploitation limits. Further increase in exploitation of the resources may hamper the sustainability of the stocks and may lead to detrimental impact on the trophic interactions of the fishery resources. Technical interventions are needed in the field of post-harvest and value addition for attaining fair economic returns from the harvest which at present forms a low-value high-volume fishery. Sustainable exploitation and management measures need to be introduced and implemented for the Acetes sp. in order to sustain the stocks and to maintain the integrity of the fishery ecosystem.

在这项研究中，分析了九种商业开发的渔业资源的饮食组成，这些资源占印度西北海岸鱼类总上岸量的55-60％。选定鱼类的肠道含量分析表明，猎物的捕食成分和捕食者偏好存在显着差异。饮食矩阵显示Acetes sp。（32.74％）是主要的共同猎物，其次是中生鱼类（30.51％），其他虾类（11.00％），消化材料（7.42％），螃蟹（4.03％）和头足类动物（2.77％）等。在这项研究中，醋栗菌被认为是非对虾的代表，因为它对非对虾的总着陆量有重大贡献（92％）。有针对性的采掘醋sp。由于鱼粉厂的需求，最近的集约化增长（从2004年的4.4亿吨增加到2018年的140万吨），年均增长率为11.2％。考虑到其生态和渔业重要性，Acetes sp。应该被视为生态系统中的重点物种。该谢弗过剩生产模型被用来计算所述模型拟合是公平的（R生物学参考点（BRPS）和模型参数MSY，FMSY，R，EMSY和K ²  = 0.630），并观察到显著正相关CPUE之间_观察到和CPUE_模型。估计的渔业最佳开采极限（p <0.05）为最大可持续产量（MSY）为12亿吨，捕捞MSY所需的捕捞努力量（EMSY）为5130万吨。但是，最近的开采产量和捕捞努力超出了最佳开采极限。对资源的进一步开发可能会妨碍种群的可持续性，并可能对渔业资源的营养相互作用产生不利影响。在收获后和增值领域需要技术干预，以从收获中获得公平的经济回报，目前该收获形成了低价值的大批量渔业。需要为古猿引入和实施可持续的开发和管理措施sp。为了维持种群和维持渔业生态系统的完整性。
