Length weight relationships (LWRs) were estimated for four species of low value fishes that belongs to four families from the southwest coast of India. The specimens of, Callionymus margaretae, Dactyloptena peterseni, Rogadius serratus and Minous inermis were collected for a period of 1 year from the fishing trawlers of Cochin Fisheries Harbour (Lat. 09° 56′ 327″ N, Long. 76° 15′ 764″ E). The estimated allometric coefficient b values ranged from 2.5020 (Rogadius serratus) to 3.2438 (Dactyloptena peterseni) and r² values ranged from 0.9492 (Rogadius serratus) to 0.9869 (Dactyloptena peterseni). All the LWRs were highly significant, with p < .001.This study provides the first estimate of LWRs for these low value by catch fish species.

“印度西南海岸四种非商业鱼类的长度重量关系”

估计了来自印度西南海岸四个科的四种低价值鱼类的长度重量关系（LWR）。的标本，䲗属margaretae，Dactyloptena peterseni，Rogadius锯和Minous麦收集从知渔业港（纬度的拖网渔船期为1年的09°56'327“N，龙。76°15'764”。 E）。所估计的异速系数b的值从2.5020（不等Rogadius锯）至3.2438（Dactyloptena peterseni）和- [R ^2个值从0.9492（不等Rogadius锯）至0.9869（Dactyloptena peterseni）。所有的轻水堆均具有高度显着性，p  <.001。本研究首次对捕捞鱼类低价值的轻水堆进行了估算。
