잉어에 의한 두 가지 유기린계(有機燐系) 살충제의 생물농축(生物濃縮)을 추구(追求)하기 위하여 실험실 조건하에서 수행한 실험결과 는 다음과 같다. 1) Diazinon과 fenitrothion의 1 ppm농도에서 잉어에 의한 생물농축계수(生物濃縮係數)는 24시간후에 각각 31과 57이었다. 이 계수(係數)는 잉어의 부위(部位)에 따라 달리 나타났는 바 내장(內臟)>기타 부위>아가미>근육(筋肉)의 순서로 나타났다. 2) 잉어를 fenitrothion의 세가지 농도에 28일간 노출시킨 결과 생물농축계수(生物濃縮係數)는 $96{\sim}138$로 나타났는 바 수중(水中)농도가 높을수록 적게 나타났다. Fenitrothion의 생체내(生體內) 농축(濃縮)은 계속적으로 일어났으며 조직내(組織內) 농도가 약 3.5ppm에서 평형(平衡)에 도달하였다.

Large quantities of by-products—such as fish frame, head, skin and viscera—are generated during seafood processing, and these by-products are not utilized extensively. Therefore, sea rainbow trout Oncorhynchus mykiss (SRT) frame muscle (FM) jerky was prepared by grinding SRT-FM, followed by mixing with seasoning, forming and drying. The nutritional and microbiological characteristics of the SRT-FM jerky were then investigated. The proximate composition of the SRT-FM jerky was 19.1% moisture, 38.7% crude protein, 7.9% crude lipid and 4.4% ash. The viable bacterium count of the SRT-FM jerky was 3.9 log CFU/g, and Escherichia coli and Staphylococcus aureus were not detected. The total amino acid content of SRT-FM jerky was 37.3 g/100 g, and the major amino acids were aspartic acid, glutamic acid, leucine and lysine. Based on the recommended daily intake of fish jerky (100 g), the most abundant mineral was potassium. The fatty acid composition of the SRT-FM jerky was 26.2% saturated acid, 34.5% monoenoic acid and 39.3% polyenoic acid, and the major fatty acids were 16:0, 18:1n-9, 18:2n-6, 20:5n-3 and 22:6n-3. These results suggest that SRT-FM jerky has high nutritional value.

This study was conducted to investigate effects of dietary lipid level on growth and body composition of juvenile red sea bream in low temperatures. Duplicate groups of fish (initial body weight of 79 g) were fed one of three isonitronic diets (47% crude protein) containing different lipid levels (10%, 17% and 22%) for 25 weeks during the winter season. Weight gain and survival of fish fed 17% lipid diet were significantly (P<0.05) higher than those fish fed the 10% or 22% lipid diet. Protein efficiency ratio, daily feed intake, condition factor, hepatosomatic index and viscerasomatic index were not affected by dietary lipid level, but feed efficiency of fish fed 10% lipid diet was significantly (P<0.05) lower than those fish fed the 17% or 22% lipid diet. Proximate composition of the whole body, liver, viscera and dorsal muscle were not significantly different among all groups except for crude protein content of dorsal muscle. The contents of 16:0, 18:0, 20:4n-3 and 20:5n-3 of the whole body were significantly (P<0.05) affected by dietary lipid level. The results of this study suggest that an increased dietary lipid level from 10% to 17% can improve growth of juvenile red sea bream in low temperature periods.

넙치, Paralichthys olivaceus (Temminck et Schlegel)에서 급이와 절식이 생존과 성장 및 표현형질에 미치는 영향을 파악하기 위해 12주에 걸친 급이와 절식 실험을 수행하였다. 실험 기간중 절식군의 생존율은 급이군에 비해 낮았다. 기아는 비만도, 일일성장률, 체중 성장률 및 실험 종료시 체중에서의 감소를 보이는 성장 저해를 나타낸 반면, 급이군은 지속적이고 양호한 성장을 보였다. 절식군은 급이군에 비하여 유사한 dressing비와 내장괴지수를 보였으며, 낮은 내장괴제거 체중을 보였다(P<0.05). 본 연구 결과, 급이와 절식 파악에 사용된 표현형질은 본 종의 영양 상태 확인의 지표로 유용하며, 넙치 표본시의 성장 시기 평가 결정에 유용하리라 사료된다.

This study was conducted to compare the sensory and enzymatic properties of Israeli carp Cyprinus carpio muscle (ICM) according to size [normal large (NLF) and small fish (NSF)], part [ventral (VM) and dorsal muscles (DM)], and commercial value [NLF, recessive (RF), or deformed fish (DF)]. There was not difference in salty of all samples. The sourness was stronger in NLF and DM than in NSF, RF, and DF, and VM, respectively. The umami of ICM showed no size-associated differences; however, those of DM, and DF and RF, were superior to those of the VM and NLF, respectively. The sweetness was also stronger in NLF than in NSF and RF, and in DM than VM. The sweetness of DF didn't differ compared to those of NLF and RF. The intensity of fish odor was weaker in NSF or DF than that in NLF, and was higher in DM than in VM. The color of ICM was bright in NSF and DF compared to NLF. Enzyme activity was very low in the muscles and high in viscera. Therefore, ICM could be used as a material for seafood products, regardless of size, part, and commercial value; however, the issue of lipid oxidation must be considered.

A feeding trial was carried out to Investigate the effect of lipid level and herb mixture in the diets on growth of juvenile parrot fish, Oplegnathus fasciatus. Two plicate groups of fish averaging 4.5 g were fed four experimental diets containing herb mixture (0 and 5 g/kg diet) at each of two lipid levels $(8\%\;and\;16\%)$ for 8 months from summer to spring (water temperature, $7.2-25.4^{\circ}C)$. Weight gain improved with increasing dietary lipid level or supplementation of herb mixture during the first 4 months feeding period. Weight gain of fish fed the diet containing $16\%$ lipid level was significantly higher (P<0.05) than that of fish fed the diet containing $8\%$ lipid level. Weight gain of fish fed the diet with herb mixture was significantly higher (P<0.05) than that of fish fed the diet without herb at the $16\%$ lipid level. Feed efficiency was influenced by dietary lipid level or herb mixture during the first 4 months. On the other hand, weight gain and feed efficiency were not affected by dietary lipid level and herb mixture after 4 months until end of feeing period. Survival of fish fed the diet containing $8\%$ lipid without supplementation of herb mixture was the lowest among the groups (P<0.05). Lipid contents of liver and viscera tended to increase with increasing dietary lipid level during the first 4 months feeding period, however muscle lipid content was not influenced by dietary lipid and herb. Total cholesterol of serum was influenced by dietary lipid level during the first 4 months feeding period. These results indicate that an increase of dietary lipid level from $8\%\;to\;16\%$ and supplementation of herb mixture can improve growth performance of juvenile parrot fish when water temperature is optimum for growth such as the summer season in Korea.
