Twenty-eight additions to the length-weight and length-length relationships of Indo-Pacific fishes from the Davao Gulf, Philippines

Abstract

SummarySelected fish were measured on markets along the Davao Gulf, Philippines between 2009 and 2016, augmenting the number of Length-Weight relationships (LWR) published earlier for the same area. LWRs were calculated for 28 fishes including those of 12 firstly reported, rare species. SL-TL and SL-FL relationships were determined for 28 and 25 species (also including 8 and 12 newly reported relationships, respectively).Minimum size at which individuals start developing forked tails are provided for Fish were weighed on a portable weighing scale (1 g accuracy). | MATERIALS AND METHODS MostFish were not sexed and data analyses were conducted without considering differences between males and females. The position of the eyes was recorded for the flatfish Psettodes erumei. Formulas TL = p + q × SL and FL = s + t × SL were used for calculating LLRs.
