Length-weight
relationships (LWRs) were estimated for five needlefish species such as
Ablennes hians (Valenciennes, 1846), Tylosurus crocodilus (Péron & Lesueur, 1821),
Tylosurus acus melanotus (Bleeker, 1850), Strongylura leiura (Bleeker, 1850), and Strongylura
strongylura (van Hasselt, 1823). Specimens were collected on weekly basis from Cochin
Fisheries Harbour (Lat. 09056′327″N, Long. 76015′764″E), Munambam Fisheries
Harbour (Lat. 10010′965″N, Long. 76010′258″E), Kalamukku (Lat. 09059′924″N, Long.
76014′564″E) and Chellanam (Lat. 09047′950″N, Long. 76016′551″E), between
October 2015 to August 2017. Fish were captured by traditional long liner (hook no. IX-XIV)
and ring seiner (mesh size 8–24 mm). The estimated allometric co-efficient
b values
ranged from 3.063 (Tylosurus acus melanotus) to 3.962 (Strongylura leiura) and r2 values
ranged from 0.850 (Tylosurus acus melanotus) to 0.992 (Tylosurus crocodilus). All the LWRs
were highly significant, with p < .001. In addition, the study provides the first estimate of
LWR for Tylosurus acus melanotus and new estimate for other four species of needlefish.
