초록

메기 (Silurus asotus)를 대상으로 210일간 기아 시 계측형질 및 체 절단면 형질을 측정하여 그 기아 효과를 조사하였다. 실험 종료시 섭이군의 생존율은 92.2±0.47% 였으며, 기아군에서는 74.4±2.59%의 생존율을 보였다. Ls, DALPO/Ls, DADOP/Ls, ED/Ls, CH/Ls, BDAA/Ls, BDMA/Ls 및 BWAA/Ls의 8개 항목에서 유의한 차이를 보였으며 (p<0.05), 다른 16개 항목 DALAD/Ls, DPDPL/Ls, HPLAA/Ls, HALAV/Ls, HALOP/Ls, DAUPO/Ls, DADAV/Ls, DADAA/Ls, Max BL/Ls, Man BL/Ls, LD/Ls, HWOP/Ls, DAUF/HL, DAUS/HL, IW/HL 및 DAUE/HL에서는 초기군, 섭이군 및 기아군의 세 그룹 간 유의한 차이가 없었다 (p>0.05). 섭이군은 각 체 절단면에서 기아군보다 더 높은 전체 높이 (THX), 더 넓은 너비 (WX) 및 더 넓은 면적 (AX)을 보였다. 본 연구는 메기의 기아 상태에 대한 외형 및 체 절단면 형질에 대한 정보를 제공한다. 이는 메기에 대한 먹이 조절에 대한 방법을 보조하고 영양상태를 나타내는 기본 기초자료로 활용될 수 있을 것이다. 또한, 본 연구에서 사용한 조사 분석 방법을 타 어종에서 적용 시 그 영양 상태에 대한 정보를 파악하는 데 유용하게 활용될 수 있을 것으로 사료된다.

Abstract

A 210-day experiment was conducted to examine the effects of starvation on survival, external morphometric traits, and sectioned morphometric traits in Far Eastern catfish (Silurus asotus). The survival rate decreased to 92.2±0.47% in the fed group and to 74.4±2.59% in the starved group. Eight dimensions of Ls, DALPO/Ls, DADOP/Ls, ED/Ls, CH/Ls, BDAA/Ls, BDMA/Ls, and BWAA/Ls showed significant differences (p<0.05), and 16 other dimensions of DALAD/Ls, DPDPL/Ls, HPLAA/Ls, HALAV/Ls, HALOP/Ls, DAUPO/Ls, DADAV/Ls, DADAA/Ls, Max BL/Ls, Man BL/Ls, LD/Ls, HWOP/Ls, DAUF/HL, DAUS/HL, IW/HL, and DAUE/HL were not significantly different among the initial, fed, and starved groups (p>0.05). The fed group showed higher total height (THX), wider width (WX), and larger area (AX) than those of the starved group in each body section. This research provides information on the morphometric traits and body sections of starved Far Eastern catfish. These results can be used as a basic guide to indicate nutritional status and assist in aquaculture methods for Far Eastern catfish. Moreover, the methods used in this study were considered helpful because the survey analysis method can be used to investigate information on the nutritional status of other fish species.
