Bycatch of trawl fishery is a global concern and batoid fishes, including skates, rays and guitar fishes, are caught frequently as non-targeted species in commercial trawl fishery of India. While the commercial batoid species are documented separately in fishery data, a large number of non-commercial species do not form part of fishery data, even though many such species are listed as ‘Data Deficient’ in IUCN red list. A survey was conducted from July 2018 to June 2019 in the major harbours and landing centresof the south coasts of India to monitor the non-commercial batoid species in the trawl bycatch. Massive landings of non-commercial batoid species such as Torpedo sinuspersici, Narcine cf maculata, Orbiraja powelli Acroteriobatus variegatus and the occasional occurrence of Dipturus johannisdavisi, Benthobatis moresbyi, Narcine timlei and Plesiobatis daviesi have been recorded, besides the juveniles, sub-adults and few adults of commercial species Rhinobatos annandalei, Brevitrygon imbricata and Neotrygon indica from south India. The non-commercial batoids mainly inhabit continental shelf and slope regions of Indian coast where fishing pressure and efforts are high. When these k-selected species live in fishing zones with intense fishing pressure, data deficient species of batoids should be considered as threatened, and this paper discuss challenges in the sector, and forwards strategies for conserving non-targeted batoids.

拖网捕捞的兼捕是全球关注的问题，在印度的商业拖网捕捞中，包括滑冰，射线和吉他鱼在内的蝙蝠类鱼类经常作为非目标物种被捕捞。尽管在渔业数据中分别记录了商业类杆菌种，但许多非商业物种并未构成渔业数据的一部分，即使许多此类物种在IUCN红色名录中被列为“数据不足”。从2018年7月至2019年6月，在印度南海岸的主要港口和登陆中心进行了一项调查，以监测拖网兼捕中的非商业蝙蝠类物种。非商业性蝙蝠类物种的大规模着陆，例如：鱼雷鱼雷，Narcine cf maculata，鲍氏Orbiraja powelli杂食性杂食蟹（Acroteriobatus variegatus），以及偶然发生的除了印度南部的商业物种Rhinobatos annandalei，Brevitrygon imbricata和Neotrygon indica的少年，亚成年和成年外，还记录了Dipturus johannisdavisi，Benthobatis moresbyi，Narcine timlei和Plesiobatis daviesi。非商业类杆菌主要栖息在印度沿海的大陆架和斜坡地区，那里的捕鱼压力和工作量很大。当这些k选择的物种生活在捕捞压力大的捕鱼区时，应将数据不足的类蝙蝠物种视为威胁物种，本文讨论了该领域的挑战，并提出了保护非目标类蝙蝠的策略。
