This study examined the effects of dietary glycoprotein extracted from Porphyra yezoensi on growth performance and resistance against the pathogenic bacteria Edwardsiella tarda in olive f lounder. A porphyra-originated glycoprotein (P) was extracted using sequential processes of water and ethanol treatment. P extracts were added to a f ishmeal-based diet at concentrations of 0.0, 0.5, and 1.0% (designated as Con, P0.5, and P1.0, respectively). Fish were fed one of the three experimental diets for 10 weeks. All f ish groups exhibited over 96.7% survival during the experimental period. Results indicated that the f ish fed diets containing P showed an increase in growth performance, including enhanced weight gain, specif ic growth rate, and feed eff iciency. An increase in insulin-like growth factor (IGF-1) was observed in the f ish fed the P1.0 diet, as compared to those fed Con. At the end of the 10-week feeding trial, all f ish were infected with E. tarda, and accumulated mortality was monitored for 8 days. Fish fed the Con diet exhibited increasing mortality from day 3 to the end of the challenge test, whereas the mortality of P-fed f ish ceased at day 5. We suggest that supplementation with P-originated glycoprotein in aquafeed may increase growth performance and resistance against pathogenic bacteria in olive f lounder juveniles.

Two consecutive studies were conducted to evaluate the effects of dietary supplementation with fermented garlic powder (FGP) or fermented garlic fluid (FGF) on growth performance, immune responses, and disease resistance of olive flounder Paralichthys olivaceus . In experiment I, olive flounder (BW: 65 g) were fed four experimental diets formulated to contain 0%, 0.5%, 1%, and 1.5% FGP (designated as FGP-0, FGP-0.5, FGP-1, and FGP-1.5, respectively). After the 10-weeks feeding trial, feed intake was significantly lower in fish fed the FGP-0.5 and FGP-1.0 diets, as compared to those fed the control diet. Fish fed the FGP-0 and FGP-0.5 diets showed significantly lower survival, as compared to the other treatments. Dietary supplementation with FGP resulted in higher non-specific immune responses than the FGP-0 group. Plasma cholesterol and triglyceride levels decreased as dietary FGP level increased. In experiment II, olive flounder (BW: 65 g) were fed four experimental diets for 10 weeks. The diets were prepared with a commercial expanded pellet to have 0%, 0.25%, 0.5%, and 1% FGF (designated as FGF-0, FGF-0.25, FGF-0.5, and FGF-1, respectively) by adsorption. At the end of the second feeding trial, feed intake was significantly lower in fish fed the FGF-0 diet, as compared to other treatments. Fish fed the FGF-0.25 and FGF-0.5 diets exhibited significantly lower cholesterol levels, as compared to other treatments. Lysozyme activity significantly increased with increases in dietary FGF. Cumulative mortality in a challenge test with Streptococcus iniae was significantly lower in the fish groups fed FGF-supplemented diets than in fish fed the control diet. The results of this study indicated that dietary supplementation with FGP or FGF can enhance the non-specific immune responses and disease resistance of olive flounder against S. iniae .

Two feeding trials were conducted to investigate the optimum feeding rates in juvenile olive founder Paralichthys olivaceus fed practical expanded pellet(EP) containing 58.1% crude protein, 10.7% crude lipid, and 10.8% ash at low and high water temperatures. In the first experiment, triplicate groups of 15 fish with average weight of 7.7 g were fed at one of seven feeding rates(0, 1, 1.5, 2, 2.25, or 2.5% of body weight/day or to satiation) for 4 weeks at low water temperature. In the second experiment, quadruplicate groups of 20 fish with average weight of 5.5 g were fed at one of eight feeding rates(0, 3, 3.5, 4, 4.25, 4.5, or 4.75% of body weight/day or to satiation) for 4 weeks at high water temperature. Based on growth performance, we estimated that the optimum feeding rates for juvenile olive flounder were 1.97-2.51% and 4.82-6.36% of body weight/day at low and high water temperatures, respectively.

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 evaluated fermented soybean meal (FSM) as a fish meal (FM) replacement and determined the appropriate amount of FSM in juvenile olive flounder diet. Twenty-four aquaria with a flowing-water system were stocked with fish averaging 20.9 g at a density of 25 fish/tank. Five experimental diets were prepared replacing FM with 0, 10, 20, 30, or 40% FSM based on FM protein (designated FSM0, FM10, FSM20 FSM30, and FSM40, respectively). Two additional diets were prepared that replaced 30 or 40% of the FM with FSM with added amino acids (methionine and lysine) (designated FSM30+AA, and FSM40+AA, respectively). Fish (triplicates)were fed one of the eight experimental diets (50% crude protein and 16.7 kJ available energy g-1 diet) for 8 weeks. Survival did not differ among the treatments during the feeding experiment. There were no significant differences in weight gain (WG) or specific growth rate (SGR) among the fish fed diets with up to 30% of the FM replaced. However, fish fed FSM40 or FSM40+AA had a reduced WG and SGR, as compared to FSM0 (control) (P < 0.05). The feed efficiency and apparent digestibility showed a similar trend (P < 0.05). The proximate composition in the whole body of fish differed only between the control and FSM40 for the crude protein level and between the control and FSM30+AA for the crude lipid level. The whole-body amino acid composition did not differ among treatments. No significant differences were found between the diet groups with and without amino acid supplementation,indicating that amino acid supplementation had no effect. The major finding of this study is that fermented soybean meal may replace up to 30% of fish meal without amino acid supplementation for normal growth of juvenile olive flounder

Two consecutive feeding trials were conducted to evaluate the effects of extruded pellet (EP) and raw fish-based moist pellet (MP) in the juvenile (experiment I) and sub-adult (experiment II) stages of olive flounder, Paralichthys olivaceus . The fish were distributed randomly to three aquarium tanks, as a group of 1,200 fish (initial mean weight 13.5±1.76 g) in experiment I, and as a group of 390 fish (initial mean weight 385±15.3 g) in experiment II. In experiment I, the weight gain, specific growth rate, feed efficiency, protein efficiency ratio, and survival of fish fed EP were all significantly higher than those of fish fed MP. In experiment II, no significant differences were observed in weight gain, specific growth rate and survival between the EP and MP groups. However, the feed efficiency and protein efficiency ratios of fish fed EP were significantly higher than those of fish fed MP. The results of this study indicate that EP could be developed to replace MP for market size production of olive flounder without any adverse effects on the growth performance. The dietary formulation used in this study could be used as an appropriate feed for olive flounder.
