LENGTH-WEIGHT RELATIONSHIP AND CONDITION FACTOR OF RIVER SPRATS, Clupeichthys sp. FROM TASIK KENYIR, TERENGGANU, MALAYSIA

Abstract

The length-weight relationship (LWR) and condition factor for river sprat, Clupeichtys sp. from Tasik Kenyir was determined and qualitatively compared with the other known species within the genus in Southeast Asia. A total of 408 individuals were collected from the mouth of Sungai Cacing, one of the main feeder rivers in Tasik Kenyir. Total length of the individuals ranges from 2.80 to 4.60 cm, while their body weight ranging from 0.10 to 0.80 grams. The mean of the total length is 3.80 ± 0.32 while the mean for total weight is 0.50 ± 0.20. The growth pattern for this species was given by the b value of 2.94, which is slightly lower than that of the reported b values for C. aesarnensis (3.27 and 3.21) from Thailand, but higher than that of the reported b value for Clupeichthys goniognathus (2.67) from Indonesia. The relative condition factor was 1.01 ± 0.23, almost similar to other reported values for Clupeichthys spp. in Southeast Asia. This is the first report on the length-weight relationship and condition factor of river sprat from this genus in Peninsular Malaysia.

Freshwater fishes (Actinopterygii) of Kenyir Reservoir, Peninsular Malaysia: Updated checklist, taxonomic concerns and alien species

“…More studies also are encouraged to be done on other species especially in the Data Deficient category especially Tor tambra ( Walton et al 2016 ) and Betta stigmosa ( Low 2019 ) for the updated status on their distribution and populations. We also did find any species in the ghost nets in the streams that are vulnerable to migratory fish species especially, cyprinids fish, concurrent with the finding of Aqmal-Naser and Ahmad (2020) , which found dead Tor tambra entangled in the ghost net. Nevertheless, it is very difficult to monitor or control the fishing activities in Kenyir Reservoir due to its massive waterbody and limited enforcement.…”

“…(Fig. 3 ) are neither of these species and need further study on their taxonomic identities ( Aqmal-Naser et al 2021 ).…”

“…In this present study, r 2 value for E. fluviatilis was 0.9244) and r 2 value of 0.8531 was obtained for H. quoyi showing a high degree of correlation. Aqmal-naser et al, (2021) [1] reported b value of 2.94 for the closely related species river sprat, Clupeichtys sp. from Tasik Kenyir, in Peninsular Malaysia.…”
