Length-weight relationship of stingrays in Kuala Selangor, Malaysia

Abstract

Summary Length‐weight relationships of three sympatric species of stingrays from a coastal mudflat, Malaysia were estimated. A total of 290 individuals (150 Himantura walga, 78 Dasyatis bennetti, and 57 Dasyatis zugei) were sampled using barrier net, gill net and beam trawl. The length‐weight relationship based on disc length and width generally showed positive allometric growth (b > 3) for all species. This study reports the first findings regarding the length‐weight relationships of these stingray species in Malaysian waters.

Length-weight relationships for 10 elasmobranch species from the Oman Sea

“…Most ray species showed LWRs similar to previous studies (Basusta et al., ; Lim et al., ). Also comparing data from Lim et al.…”

“…Also comparing data from Lim et al. (), both the DL‐W and DW‐W relationships were in general statistically significant, indicating that the observed length–weight relationships were credible.…”

Length-weight and length-length relationships of four endemic fish species caught from Payra River, Southern Bangladesh

“…The estimated b value was 3.17 for G. cenia which is almost similar in Ravi River (3.15), north western India (Sharma, Mir, Singh, Akhtar, & Pandey, ). These variations could be related to different environmental and biological factors such as temperature, salinity, food (quantity, quality and size), habitat and gonad development, spawning period season, sex, season, stomach fullness, length range of sampled specimens and health (Hanif, Siddik, Chaklader, et al., ; Lim, Chong, Lim, & Yurimoto, ; Siddik, Hanif, Chaklader, Nahar, & Fotedar, ).…”

Length-weight relationships for four stingray species from the tropical Atlantic Ocean

“…All fitted regressions were highly significant; the estimated b values ranged from 2.88 to 3.37, falling within the expected range of 2.5–3.5, which validated all length–weight relationships reported herein (Froese, ). Although the absence of sex differences in the LWRs appears to be a common pattern for stingrays (Filiz & Mater, ; Lim et al., ; Naderi, Zare, & Azvar, ), significant differences were found for D. marianae , an endemic species from the northeastern coast of Brazil (Rosa, Gadig, & Gomes, ). These differences may be the result of a variety of factors such as fish condition, seasonality, length range and even the sample size (Haimovici & Velasco, ).…”
