In this study, Arius maculatus were collected using the samples caught by bottom trawling off the southwestern coast of Taiwan. Length-weight and length-length, fork (FL) , standard (SL) and total (TL) lengths, relationships were determined. The relationships between the lengths were all significantly linear (p<0.01), the b value in the length-weight relationship for this value was significantly lower than 3 in the fall (p<0.01), when the temporal changes were taken into account, indicating that only the sampling time affected the growth pattern of A. maculatus.The growth was isometric in the spring, summer and winter, but it was negative and allometric in the fall.

We estimated the relations between total length (TL) and opercular (G ope) and maximum (G max) girths, for the eight most representative lagoon fish species in Mesolonghi-Etolikon lagoons within 2015-2017 (June through December). The following species were studied: Chelon LGR estimates were not available. Results showed that both G ope and G max increased significantly linearly with TL for all studied species with all r 2 values being higher than 0.862. When G max values were plotted against TL for all species combined, two significant (ANCOVA, P < 0.05) length-girth relations were identified corresponding to different body shapes. The implications of girth measurements for lagoon gear selectivity estimates are also discussed.

Length-weight relationships are presented for five fish species from Chi-gu in southern Taiwan. At present, two of these species have no estimates in FishBase.
