Length-weight relationships of six fishes from intertidal and coastal waters in the northern Persian Gulf

Abstract

Summary The length–weight relationships (LWRs) for six little‐known fish species collected in the northern Persian Gulf (south of Iran) are presented, namely, Plicofollis dussumieri, Pseudotriacanthus strigilifer, Cynoglossus bilineatus, Cynoglossus arel, Solea elongata, and Pseudorhombus elevates.

Length-weight relationships for eight fish species from the Pearl River Delta, China

“…Similar results were also found in many species in other areas, e.g. Cynoglossus arel of the northern Persian Gulf (Aghajanpour et al, 2015), Schizopygopsis thermalis and Schizothorax nukiangensis in the upper Nujiang-Salween River of China (He et al,2015), and Carassius carassius in the Nakdong River of South Korea (Lee et al,2015), etc. These studies show that even fish species with similar body shapes will also show significantly different a and b values in their LWRs.…”

Length-weight relationship of four fish species of the genera Pseudorhombus, Plicofollis and Scarus (Actinopterygii: Paralichthyidae, Ariidae and Scaridae) from the Persian Gulf, Iran

“…In the LWRs, the b value was expected to be in the range of 2.5-3.5 (Froese, 2006) or 2-4 (Tesch, 1971) as was found in the present study. Dutta and Hazra (2013), Cheraghi et al (2013), Aghajanpour et al (2015), Farooq et al (2017) and Mohseni et al (2019) in their studies reported the b parameter 2.984, 2.979, 2.777, 2.968, and 2.95 for P. dussumieri, respectively, whereas in our study the value was 2.38, showing a negative allometric growth pattern. The parameter b-value of S. fuscopurpureus was reported to be 3.17 (versus 2.41 in the present study) (Javadzadeh et al, 2016).…”

Length-weight relationships for 15 fish species of the Xun Jiang River in Guangxi, China

“…All b-values varied within the expected rang except for G. guilinens (estimated b = 2.364) and P. jordani (estimated b = 3.634), which might be due to the gonad maturity and sex of the captured specimens. The high b and corresponding low a for Ptychidio jordani and Sinibotia pulchra could be due to the small size range, which was similar to the C. arel (Aghajanpourl et al, 2015).…”
