Length-weight and length-length relationships of 139 Indo-Pacific fish species (Teleostei) from the Davao Gulf, Philippines

Abstract

Length-weight relationships (LWRs) of 139 coral reef and pelagic fish species (representing 34 fish families) were calculated based on 3806 individuals measured at local fish markets near the Davao Gulf in the southern Philippines during weekly visits between March 2009 and July 2011, as well as in June 2012. Fishes were caught with a variety of fishing methods, corroborated by abrasions and injuries. Fortyseven of 139 LWRs were firstly reported and new to science. The mean slope b of the LWRs was 3.035, indicating that the majority of studied species followed isometric growth. Standard length -total length relationships were calculated for all measured fish species. Additionally, standard lengthfork length relationships are presented for 108 species. Moreover, fifteen new records of maximum fish length and weight are reported.

Age and growth of three common species of goatfish exploited by artisanal fishery in Hurghada fishing area, Egypt

“…The present b‐value of M. flavolineatus is more or less than that obtained from previous studies; Letourneur, Kulbicki, and Labrosse () gave b equal to 3.06, while the b‐value in Kulbicki, Guillemot, and Amand () was 3.101; Gumanao, Saceda‐Cardoza, Mueller, and Bos () estimated b at 2.762 from the Davao Gulf, Philippines and Peyton et al. () determined the b‐value as 3.21.…”

Length-weight and length-length relationships for six commercial fishes from southern Korean waters

“…The LWRs and LLRs estimated in FishBase, however, were based on insufficient sample numbers and narrow size ranges, which prevented direct comparisons with the results of this study. However, the LWRs and LLRs of D. berycoides , H. agrammus , H. otakii and A. schlegelii reported from the southern Korean waters (Park & Huh, ), the Davao Gulf, Philippines (Gumanao, Saceda Cardoza, Mueller, & Bos, ), the southwestern coast of Taiwan (Chu, Wang, Hou, Ueng, & Chu, ), and the Yellow Sea (Wang et al., ; Xue et al., ) used sufficient sample numbers and wider length ranges. Our LWR estimates were compared with the Bayesian estimates of LWRs in FishBase (Froese, Thorson, & Reyes, ), and fell within the ranges expected for each species or the family and body shape to which they belong.…”

Length-weight and length-length relationships of thirteen fish species from the lower Jinsha River, southwest China

“…a and b were calculated based on a simple linear regression analysis of log‐transformed data (Froese, ; Froese, Tsikliras, & Stergiou, ). The TL and SL relationships (LLRs) were estimated by the linear regression analysis of TL = p + q × SL (Gumanao, Saceda‐Cardoza, Mueller, & Bos, ). For the two analyses, extreme outliers were identified and excluded before fitting the linear regression, using the log W− log L and TL − SL plot graphs.…”
