Abstract<\/h2>\n

This study presents the length-weight relationships (LWRs) for 16 lutjanid species from Visakhapatnam coastal waters, India (16.98\u00b0<\/sup>N-20\u00b0<\/sup>.2\u00a0N, Long. 82.19\u00b0<\/sup>-86.53\u00b0E). The samples were collected fortnightly between December 2013 and December 2018 from commercially operated fishing gears viz.: the reef fish trap with single and double horse necked funnel (mesh aperture size 4.5\u00a0cm) trap measured about 3\u00a0ft in length, 4\u00a0ft in width and 2.5\u00a0ft in height, having a volume of 30 cu ft. The soak time was between 18 to 22\u00a0h. Gill nets made of monofilament nylon netting with a mesh size of 80\u00a0mm were used in the collection of snapper fishes. The nets were operated 3\u00a0h before morning (sunrise) and hauled 1\u00a0h after the sunrise. The depth of the net operated varied from 3 to 8\u00a0m, whereas the head rope of the net is around 20\u201325\u00a0m in length. The hook number 8 to 11 is used for the fishing of snapper fishery resources in water depth more than 75\u00a0m in Visakhapatnam region. The soak time varied from 5 to 10\u00a0h. The bottom trawlers (43\u00a0mm with a cod end mesh size of 15\u201325\u00a0mm) a depth range of 10 to 55\u00a0m, whereas during each fishing period, 3 to 4 hauls are made with a towing period ranging from 1 to 2\u00a0h; trawlers (a depth regime of 12 to 55\u00a0m, with a mesh size of 400\u00a0mm to 25\u00a0mm at the cod end). Around 3 to 6 hauls are made during each fishing trip with a towing period of 1to 2\u00a0h. All LWRs were significant with\u00a0r<\/em>2<\/sup>\u00a0values ranged from 0.9504 for\u00a0Lutjanus lemniscatus<\/em>\u00a0to 0.9951 for\u00a0Lutjanus fulvus<\/em>\u00a0and \u2018b\u2019 values ranging from\u00a0Pinjalo pinjalo<\/em>\u00a0for 2.5982\u00a0Lutjanus quinquelineatus<\/em>\u00a0for 3.4993. In addition, new maximum total length for each of the three species\u00a0L. indicus, L. xanthopinnis<\/em>\u00a0and\u00a0P. pinjalo<\/em>\u00a0was also found. The parameters are found great importance to evaluate the relative condition of populations, biology, ecology, species management and their fisheries and stock assessment.<\/p>\n
