This study reports the length‐weight relationships (LWR) for eight elasmobranch species; four shark species (Carcharhiniformes and Orectolobiformes), two species of rays (Myliobatiformes) and two species of guitarfishes (Rhinopristiformes) from the Coromandel Coast of Tamil Nadu, Eastern Indian Ocean. The specimens of these elasmobranch species were collected from the catches of various gears like trawl net, bottom set and drift gill net, hook & line at Chennai—Royapuram Fishing Harbour, Cuddalore Fishing Harbourand Nagapattinam Fishing Harbour situated along this coastal region fortnightly during June 2019–March 2020. The values of the parameter ‘b’ remained within the expected range of 2.5–3.5. Length‐ weight / Disc‐width‐weight relationships showed good fit with r² values varying from 0.8923 to 0.9869. This study also reports a new maximum TL length (L_max)for a shark species (Chiloscyllium griseum).

印度洋东部泰米尔纳德邦科罗曼德海岸捕获的八种弹性分支物种的长度-重量关系

这项研究报告了八种弹性分支物种的长度-重量关系（LWR）。来自印度洋东部泰米尔纳德邦科罗曼德海岸的四种鲨鱼种类（鲨鱼形和直肠类），两种射线鱼类（My形目）和两种吉他鱼（R形目）。这些弹性分支物种的标本是从金奈-罗亚普拉姆渔港，库达洛雷渔港和纳加帕蒂纳姆渔港位于该沿海地区的每两周的拖网，渔网和底钓网，钩和钓线等各种渔具的渔获物中收集的– 2020年3月。参数'b'的值保持在2.5-3.5的预期范围内。长度-重量/盘片-宽度-重量之间的关系与r ²吻合良好值从0.8923到0.9869不等。这项研究还报告了鲨鱼物种（Chiloscyllium griseum）的新的最大TL长度（L _max）。
