Relationships between sagittal otolith size and body size of Terapon jarbua (Teleostei, Terapontidae) in Malaysian waters

Length-weight relationship provides basic information of a fish's condition while the morphometric data of otolith has been traditionally used to determine the range of fish sizes for various purposes. The length-weight relationship of Terapon jarbua (Forskal, 1775) was examined from 165 specim...

The length-weight relationship of Terapon jarbua (Forskal, 1775) was examined from 165 specimens, while 132 specimens were used in sagittal otolith biometry measurements. Fish specimens were obtained from various locations in Malaysia including Pahang, Selangor, Sarawak, and Sabah. The total length of fish ranged 12.5-32.5 cm, while the total weight ranged 26.28-444.30 g. The otolith length ranged 0.423-1.070 cm, and the otolith weight was 0.010 3-0.157 2 g. The specimens displayed a mixture of positive and negative allometry growth as indicated by fluctuating b values between 2.74 and 3.15.
