Length–weight relationship (LWR) was estimated for 12 elasmobranch species; five
shark species, four species of rays and three species of guitar fishes from north-eastern
Arabian Sea, India. Five major landing centres of Maharashtra were selected;
Satpati (Lat. 19°43′15″N, Long. 72°42′00″E), Naigaon (Lat. 19°19′32″N, Long.
72°48′54″E), Versova (Lat. 19°08′33″N, Long. 72°48′11″E), New ferry Wharf (Lat.
18°57′29″N Long. 72°51′01″E) and Sassoon dock (Lat. 18°54′42″N, Long.
72°49′33″E). Samples were collected fortnightly during August 2016 to October
2017 from various gears; drift gill nets (Hung length 114–143 m and #100–270 mm)
off Satpati coast at 35–50 m depth, dol nets (length 50–65 m and cod end #
30–69 mm) in Naigaon at 38–50 m depth and trawl (length 33–72 m and cod end #
17–32 mm) in Versova, New ferry Wharf and Sassoon dock operated at 20–50 m
depth. Multiday fishing was carried out with 2–3 fishing trips in a month, each trip
with duration of 7–13 days. Soaking time of gill net and dol net varied from 4 to 8 hr
while each trawl haul lasted for 3–4 hr. Length–weight/Disc-width-

showed good fit with r2 values varying from 0.818 to 0.999. In addition to information
on LWR, new maximum size for three species of elasmobranchs is reported in
this paper.
