This study was used to lift nets and trap net fishing at intertidal zone of lagoon and
estuarine regions of southern Taiwan. From July 2013 to July 2018, a total 420
specimens of Pisodonophis were analyzed, the average total body length (TL) and average body weight (W)
of P. boro eels
are 68.4 ± 11.9 cm and 140.4 ± 86.1 g (N = 194), respectively. Typically, P. cancrivorus eels are smaller
(TL = 52.8 ± 9.2 cm) and lighter (W = 107.9 ± 73.7 g [N = 119]) than P. boro eels. The natural
logarithmic linear relationships between the TL and W of P. boro and P. cancrivorus are respectively
expressed as ln(W)b = 2.4405 ln(TL)？−？5.4448 (R2 = 0.796,
N = 194) and ln(W)c = 3.2168 ln(TL) − 8.2027, (R2 = 0.934, N= 119). P.
