양식어류(養殖魚類)의 건강평가기준(健康評價基準)을 위한 기초자료(基礎資料)를 확보하고자 저자(著者)등은 1988년(年) 6월(月) 부터 1989년(年) 5월(月)까지 이스라엘잉어를 이용한 일련의 혈액조사(血液調査)를 실시하여 다음과 같은 결과(結果)를 얻었다. 1. 건강(健康)한 이스라엘잉어의 혈액상(血液像)은 Hct $32{\pm}3.4%$, Hb $8.3{\pm}0.9g/dl$, RBCs $132{\times}10^4{\pm}27.6{\times}10^4mm^3$, 총단백(總蛋白) $2.7{\pm}0.7g/dl$, GOT $143{\pm}19.5units$, GPT $50{\pm}14.2units$, 총혈당 $70{\pm}12.6mg/dl$, BUN $7.5{\pm}1.9mg/dl$ 등이었다. 2. 온수의 변화(變化)에 따른 혈액상(血液像)은 $23^{\circ}C$를 대조군(對照群)으로하여 $5^{\circ}C$ 하강(下降)시($18^{\circ}C$) Hct 및 RBCs수(數)가 감소(減少)하였으며, $5^{\circ}C$ 상승(上昇)시($28^{\circ}C$) Hct, RBCs수(數) 및 glucose량(量)이 증가(增加)하였다. 3. 용존산소량(溶存酸素量)의 변화(變化)에 따른 혈액상(血液像)은 4.5ppm을 대조군으로 하여 용존산소 감소(減少)시(3ppm) Hct 및 RBCs수가 증가(增加) 하였으며 용존산소 증가(增加)시(7ppm) Hct 및 RBCs수가 감소 하였다. 4. 연쇄구균(連鎖球菌) $10^6cells$/fish를 근육(筋肉)에 접종(接種)한 경우 염증성(炎症性) 반응(反應)과 함께 Hct, RBCs, glucose, BUN치(値)가 현저(顯著)히 감소(減少) 하였으며 이들은 6 일(日)만에 회복 되었다. 5. 연쇄구균 $10^4cells$/fish를 복강내(腹腔內)에 접종한 경우 역시 염증성 반응과 함께 Hct, RBCs, BUN치(値)가 감소 되었으나, 이 경우 폐사(斃死)된 예(例)는 없었다. 6. Edwardsiella tarda균 $1.2{\times}10^8cells$/fish를 근육(筋肉)에 접종한 경우 Hct 및 RBCs치(値)는 감소하였고, TCHO, GOT, GPT, BUN치(値)는 증가 하였으며, 격심(激甚)한 염증성(炎症性) 반응(反應)과 함께 접종 3~4일(日) 내(內)에 접종어(接種魚)의 60%가 폐사(斃死)하였다.
The purpose of this study was to obtain the fundamental data for health assessment of cultured fishes. A series of hematological studies and blood chemistries were made on cultured israeli carps from May, 1988 to May, 1989. The results of this study were as followings : 1. The blood constituents of healthy carps were Hct $32{\pm}3.4%$, Hb $8.3{\pm}0.9g/l$, RBCs $132{\pm}27.6({\times}10^4cm^3)$), Total protein $2.7{\pm}0.7g/dl$, GOT $143{\pm}19.5U$, GPT $50{\pm}14.2U$, Total glucose $70{\pm}12.6mg/dl$ and BUN $7.5{\pm}1.9mg/dl$, etc. 2. The blood constituents by change of water temperature with the control of $23^{\circ}C$ showed the decrease in Hct and RBCs at $18^{\circ}C$, and the increase in Hct, RBCs and glucose at $28^{\circ}C$. 3. The blood constituents by change of dissolved oxigen with the control of 4.5ppm showed the increase in Hct and RBCs at 3ppm, and the decrease in Hct and RBCs at 7ppm. 4. In the case of intramuscular injection of Streptococcus sp. with $10^6cells$/fish infection dose, there showed marked decrease in Hct, RBCs, glucose and BUN with inflammatory reaction, and the fishes were recovered in 16 days. 5. In the case on intraperitoneal injection of Streptococcus sp. with $10^4cells$/fish infection dose, there showed decrease in Hct, RBCs and BUN with inflammatory reaction, but there were no dead cases. 6. In the case of intramuscular injection of Edwardsilla tarda with $1.2{\times}10^8cells$/fish infection dose, there showed decrease in Hct and RBCs, and increase in TCHO, GOT, GPT and BUN with marked inflammatory reaction, and 60% of inoculated fishes were died within 3 or 4 days.
