This study was conducted to determine the proper inclusion levels of squid liver powder (SLP) and dehulled soybean meal (DHSM) as a fish meal (FM) replacement in the diets for olive flounders. All the experimental diets were formulated to be isonitrogenous (50% crude protein, CP) and isocaloric (17.1 kJ energy g-1 diet). Four diet were formulation of FM with SLP (DHSM) were tested at 0, 25, 50, 75% (SLP(DHSM)0, SLP(DHSM)25, SLP(DHSM)50 and SLP(DHSM)75, respectively). Triplicate groups of 12 fish with an average body weight of 5.56±0.1g(mean±S.D.) were fed one of three experimental diets for 7 weeks. Weight gain (WG) and the specific growth rate(SGR) of fish fed SLP(DHSM)0 and SLP(DHSM)25 diets were significantly higher than those of fish fed SLP(DHSM)50 and SLP(DHSM)75 diets (P<0.05). Also, WG and SGR of fish fed SLP(DHSM)50 had significantly higher WG and SGR than that of fish fed SLP(DHSM)75 (P<0.05). The feed efficiency (FE) and protein efficiency ratio (PER) of fish fed SLP(DHSM)0 and SLP(DHSM)25 were significantly higher than those fed SLP(DHSM)50 and SLP(DHSM)75 (P<0.05). The whole-body crude lipid content of fish SLP(DHSM)75 was significantly higher than that of fish fed SLP(DHSM)50 (P<0.05). However, there were no significant differences in whole-body moisture, crude protein and crude ash of fish fed all diets. Based on these growth performance results, the SLP(DHSM) combination replace up to 25% FM protein by the ANOVA test in juvenile olive flounder diets.

본 실험은 치어기 넙치에 잇어서 ${\beta}-1,3$ 글루칸을 사료내 첨가시 성장, 비특이적 면역반응 및 질병저항성에 미치는 영향을 조사하기 위하여 사료내 ${\beta}-1,3$ 글루칸을 수준별 첨가하여 실시였다. 실험어는 평균무게 3.2 g인 넙치 치어를 사용하였으며, 기초사료에 ${\beta}-1,3$ 글루칸을 대조구, ${\beta}-1,3$ 글루칸 0.01, 0.025%, 0.05% 및 0.1%를 각각 첨가하여 총 5개 실험구로 3반복배치하여 6주간 실시하였다. 총 6주간의 성장 실험결과, 면역증강물질인 ${\beta}-1,3$ 글루칸의 첨가에 따르는 사료효율과 단백질전환효율에 있어서 ${\beta}-1,3$ 글루칸 0.1%를 공급한 사료구가 대조구와 다른처리구에 비하여 유의하게 높은 값을 나타냈다(P<0.05). 증체율과 일간성장율에 있어서는 ${\beta}-1,3$ 글루칸 0.1%를 공급한 사료구가 대조구, ${\beta}-1,3$ 글루칸 0.01%, 0.025%를 첨가한 구보다 유의하게 높은 값을 나타내었지만 ${\beta}-1,3$ 글루칸 0.05%구와는 유의한 차이가 없었다. 비만도에 있어서는 ${\beta}-1,3$ 글루칸 0.05%와 0.1%를 첨가한 구가 대조구와 첨가구보다는 유의적으로 높았다. 헤마토크리트치는 ${\beta}-1,3$ 글루칸 0.05%와 0.1%첨가한 실험구가 대조구와 ${\beta}-1,3$ 글루칸을 0.01%와 0.025%를 첨가한 실험구에 비하여 유의하게 높은 값을 나타내었다(P<0.05). 혈청내 GOT에 있어서 ${\beta}-1,3$ 글루칸 0.05%와 0.1%를 첨가한 실험구가 대조구, ${\beta}-1,3$ 글루칸 0.01%와 0.025%를 첨가한 실험구보다 유의하게 낮은 값을 나타내었다(P<0.05). 비특이적 면역반응 결과에 있어서는 ${\beta}-1,3$ 글루칸을 0.05%와 0.1%를 첨가한 실험구가 혈청의 lysozyme 활성 및 두신 phagocyte의 chemiluminescent(CL) 반응에서 대조구, ${\beta}-1,3$ 글루칸 0.01%와 0.025%를 첨가한 실험구보다 유의하게 높은 값을 나타내었으나, 보체대체활성의 경로에 있어서는 전실험구간의 유의한 차이를 보이지 않았다. 공격 실험 결과에서는 ${\beta}-1,3$ 글루칸을 첨가한 실험구가 대조구에 비하여 초기폐사율이 낮음을 확인할수 있었으며, 상기 결과를 토대로, 넙치 치어의 경우 ${\beta}-1,3$ 글루칸을 0.05% 이상 0.1% 미만을 사료에 첨가하는 것이 성장, 사료효율 증진, 항산화능 및 질병저항성에 가장 좋은 효과를 나타낼 수 있을 것을 사료된다. This study was conducted to investigate the effects of dietary supplementation of ${\beta}-1,3$ glucan on growth and immune responses in juvenile olive flounder, Paralichthys olivaceus fed the white fish meal based diets for 6 weeks. Five experimental diets supplemented with ${\beta}-1,3$ glucan at 0, 0.01, 0.025, 0.05, 0.1 % (Control, $G_{0.01},\;G_{0.025},\;G_{0.05}\;and\;G_{0.1}$, respectively) of diet on a dry-matter basis. Five experimental diets were formulated to be isonitrogenous and isocaloric to contain 50.0% crude protein and 16.7 kJ available energy $g^{-1}$. Fish averaging $3.2{\pm}0.1\;g\;(mean{\pm}SD)$ were randomly distributed in each aquarium as triplicate groups of 15 fish. Weight gain (WG, %), specific growth rate (SGR, %), and feed efficiency (FE, %) of fish fed $G_{0.1}$ diet were found significantly higher than those of fish fed Control, $G_{0.01},\;G_{0.025}\;and\;G_{0.05}$ diets (P<0.05). However, there was no significant difference among the fish fed control, $G_{0.01},\;G_{0.025}$. Chemiluminescent responses (CL) of fish fed $G_{0.1}$ diet were significantly higher than those of fish fed the other diets. Serum lysozyme activities of fish fed $G_{0.05}$ and $G_{0.1}$ diets were higher than those of fish fed control, $G_{0.025}$ and $G_{0.05}$ diets. Fish fed $G_{0.1}$ diet showed a significantly lower cumulative mortality than did fish fed control diet throughout the challenge test (P<0.05). These results suggested that based on growth rate, feed efficiency, non-specific immunity and protection against microbial infections the optimum dietary ${\beta}-1,3$ gulcan could be greater than 0.05% but less than 1.0% in juvenile olive flounder, Paralichthys oilvaceus.

본 연구는 치어기 잉어에 있어서 어분 (fish meal, FM) 대체단백질원으로서 lysine 부산물 (lysine cell mass, LCM)이 사료내 이용 가능성과 대체 수준을 결정하기 위해 수행하였다. 실험사료의 조단백질 함량은 38%, 가용에너지는 15.2kJ/g (protein, carbohydrate and lipid: 16.7, 16.7 and 31.7 kJ/g)으로 동일하게 맞추어 실험사료를 제조하였으며, 사료의 조성을 요약하면 다음과 같다: LCM_0, 100% FM; LCM_20 80% FM+20% LCM; LCM_40, 60% FM+40% LCM; LCM_60 40% FM+60% LCM; LCM_100 100% LCM; LCM_20ℓ, 80% FM+20% LCM+0.07% Lysine; LCM_40ℓ, 60% FM+40% LCM+0.14% Lysine; LCM_60ℓ, 40% FM+60% LCM+0.22% Lysine; LCM_100ℓ, 100% LCM+0.35% Lysine. 6주 동안의 실험 결과, 증체율, 사료효율, 일간성장률, 간중량지수 및 단백질전환효율에 있어서 LCM_0와 비교하여 LCM_20는 유의적인 차이가 없는 반면에 (P>0.05), LCM_40, LCM_60 및 LCM_100, LCM_40ℓ, LCM_60ℓ 및 LCM_100ℓ는 유의적으로 낮게 나타났다 (P<0.05). LCM_0와 LCM_20ℓ은 증체율, 일간성장률, 간중량지수 및 단백질 전환효율에 있어서는 유의적인 차이를 보이지 않는 반면에 (P>0.05), 사료효율에 있어서는 LCM_0에 비해 LCM_20ℓ이 유의적으로 낮게 나타났다 (P<0.05). 헤마토그리트과 비만도는 모든 사료구에서 유의적인 차이가 없었다 (P>0.05). 따라서, 치어기 잉어에 있어서 lysine 부산물은 어분단백질의 20%까지 대체 가능하며, lysine 부산물에 결핍된 필수아미노산인 lysine을 첨가한 사료구애서는 첨가 효과가 나타나지 않았다. This experiment was conducted to evaluate the lysine cell mass (LCM) as a dietary fish meal (FM) protein replacer in juvenile Israeli carp, Cyprinus carpio. Fishmeal, a major animal protein source in the control diet, was replaced by LCM on the protein equivalent base. Fish averaging 1.7±0.1 g (Mean±SD) fed one of nine diets containing isonitrogenous and isocaloric basis of 38% crude protein and 15.2 kJ available energy/g diet: control, 100% FM; LCM_20 80% FM+20% LCM; LCM_40, 60% FM+40% LCM; LCM_60, 40% FM+60% LCM; LCM_100 100% LCM; LCM_20ℓ, 80% FM+20% LCM+0.07% Lysine; LCM_40ℓ, 60% FM+40% LCM+0.14% Lysine; LCM_60ℓ, 40% FM+60% LCM+0.22% Lysine; LCM_100ℓ, 100% LCM+0.35% Lysine. After 6 weeks of feeding trial, there was no significant difference in weight gain (WG), feed efficiency (FE), protein efficiency ratio (PER) and specific growth rate (SGR) among fish fed control and LCM_20 (P>0.05), while fish fed LCM_40, LCM_60, LCM_100, LCM_40ℓ, LCM_60ℓ and LCM_100ℓ diets had a significantly lower WG, FE, PER and SGR than did fish fed control diet (P<0.05). There was no significant difference in WG, PER and SGR among fish fed control and LCM_20ℓ diets (P>0.05), while fish fed LCM_20ℓ had a significantly lower FE than did fish fed control diet (P<0.05). No significant difference was observed in hematocrit and condition factor among fish fed nine diets (P>0.05). Therefore, these results indicated that LCM could replace FM up to 20% and dietary synthetic lysine supplementation did not show any positive growth effects in juvenile Israeli carp.

This study was conducted to compare an experimental extruded pellet (EP) and raw fish-based moist pellet (MP) on growth performance, whole-body and dorsal muscle composition, and textural properties of dorsal muscle for olive flounder Paralichthys olivaceus . Four groups of 8,000 fish (initial mean weight 27.1±0.05 g) per concrete tank (10×10 m) were fed the experimental diets for 16 months. After the feeding trial, no significant differences were observed in final mean body weight, weight gain, specific growth rate, feed intake, survival, and condition factor between EP and MP groups. However, feed efficiency of fish fed the EP was significantly higher than that of fish fed the MP. Moisture content in the whole-body of fish fed the MP was significantly higher than that of fish fed the EP. Significantly higher contents of polyunsaturated fatty acid (PUFA) in whole-body and dorsal muscle were observed in fish fed the EP compared with fish fed the MP. Any notable differences in amino acid contents or textural properties of the dorsal muscle were not observed in fish fed either the EP or the MP. The results of this study indicated that the EP could be developed to replace MP for the market size of production in olive flounder without the adverse effects on growth performance. Formulation of the EP could be used as a practical feed for olive flounder.

A 8-week feeding trial was conducted to investigate the effects of dietary supplementation of Kugija (Lycium chinense) on the growth and immunological response in juvenile Korean rockfish (Sebastes schlegeli). Six experimental diets were supplemented with Kugija at 0, 0.1, 0.5 1.0, 3.0 and 5.0% (K0, K0.1, K0.5, K1.0, K3.0, K5.0) on a dry-matter basis. After 2 weeks, triplicate groups of 30 fish initially averaging 3.36±0.2 g (mean±SD) were randomly distributed into the aquarium and were fed one of the experimental diets for 8 weeks. By the end of the 8-week feeding trial, fish fed the K0.5 and K1.0 diets exhibited a higher weight gain and specific growth rate than fish fed K0 and K0.1 diets (P<0.05). Feed efficiency of fish fed the K0.5 diet showed significant higher value than that of fish fed the K0, K3.0 and K5.0 diets (P<0.05). Hepatosomatic index of fish fed the K5.0 diet was significantly higher than that of fish fed the K0.1 and K5.0 diets (P<0.05). Hematocrit of fish fed the K0.5, K1.0 and K5.0 diets was significantly higher than that of fish fed the K0 diet (P<0.05). Glutamic oxaloacetic transaminase of fish fed the K0.5, K1.0, K3.0 and K5.0 diets was significantly lower than in fish fed the other diets (P<0.05). Glutamic pyruvic transaminase activity of fish fed the K3.0 diet was significantly lower than those of fish fed the K0 and K0.1 diets (P<0.05). However, there was no significant difference in the activity of the transaminase in fish fed the K0.5 K1.0, K3.0 and K5.0 diets. Lysozyme activity of fish fed the K0.5 and K1.0 diets was significantly higher than that in fish fed the K0 and K0.1 diets (P<0.05). Respiratory burst activity of fish fed the K3.0 diet was significantly higher than those of fish fed the K0 and K0.1 diets (P<0.05). However, there was no significant difference in respiratory burst activity of fish fed the K0.5 K1.0, K3.0 and K5.0 diets. Fish fed Kugija showed lower early mortality than fish fed a Kugija-free diet upon challenge with Vibrio ordalii. The results suggest that feeding of Kugija (Lycium chinense) enhances growth, non-specific immunity and disease resistance in juvenile Korean rockfish.
