쏠종개, Plotosus lineatus Thunberg 수염의 상대성장

Abstract

To facilitate estimation of the barbel size of a striped sea catfish, Plotosus lineatus Thumberg total length (TL) and head length (HL) against body weight (BW), HL against TL, and 1st maxillary barbel <TEX>$(MxBL_1)$</TEX>, 2nd maxillary barbel <TEX>$(MxBL_2)$</TEX>, 1st mandibular barbel <TEX>$(MnBL_1)$</TEX> and 2nd mandibular barbel <TEX>$(MnBL_2)$</TEX> against HL were regressed. The relationship of TL and HL for BW were described by the equation <TEX>$TL=50.9373BW^{0.3072}\;(r^2=0.9898)$</TEX> and <TEX>$HL=11.2938BW^{0.3144}(r^2=0.9572)$</TEX>, respectively. The relationship of HL for TL was described by the linear equation <TEX>$HL=0.1982TL+2.1996(r^2=0.9568)$</TEX>. The relationship of each barbel for HL described by the equation of <TEX>$HxBL_1=0.04420HL+0.3105(r^2=0.9615),\;MxBL_2=0.4592HL+0.5321(r^2=0.9519), MnBL_l=0.4057HL+1.9824 (r^2=0.9465)\;and\;MnBL_2=0.4355HL+1.8010(r^2=0.9429)$</TEX>. Knowledge of the relative growth patterns about each barbel of this species is important for the propagation of seed as stock for large-scale striped sea catfish culture.
