This study investigated the growth and energy partition of juvenile red sea bream Pagrus major (159.3±9.5 g; RSB) and hybrid sea bream P. major (♀)×Acanthopagrus schlegeli (♂) (144.8± 10.0 g; F1) on satiation feeding of fish meal (FM) and soybean meal (SM) based isocaloric diets (21.1 kJ/g diet) at 21.6℃ water temperature for 4 weeks. Two sea bream species offered no significant influence on final mean body weight, condition factor, viscera somatic index and apparent digestibility coefficient in both dietary groups, and both fish species were increased the relative stomach and intestine weight in SM than that in FM. RSB fed FM diet showed larger growth rate, feed efficiency, protein efficiency ratio, and apparent nutrients and energy retention efficiency than that fed SM diet, but this was inverse in F1. Whereas, Energy partitions of RSB and F1 in FM and SM dietary groups observed a similar tendency on fecal, digestible, urinary, metabolizable and standard metabolizable energy. However, retained energy of RSB in fed FM diet higher than that in SM, was inverse in F1. Moreover, heat increment plus voluntary activity energy consumption of F1 fed SM diet compare with fed FM diet lower than that of RSB. These results suggest that RSB and F1 has similar the energy consumption metabolism for digestive absorption in both diets, however, the energy accumulation pattern from absorbed nutrients appear to differ on SM fed.

To determine a suitable dietary protein/lipid (CP/CL) ratio in the early juvenile stages of hybrid porgy ($F_1$), female red sea bream (RSB) ${\times}$ male black sea bream, five diets with various CP/CL ratios-60/7, 55/12, 51/17, 46/23, and 41/28-were prepared and provided to juveniles in triplicate. At the smaller juvenile stage, $F_1$, weighing 0.32 g, a significantly higher specific growth rate (SGR) and feed efficiency (FE) were seen with 60/7 and 55/12 diets. However, in RSB weighing 0.26 g, SGR and FE were higher with the 60/7 diet than the other diets at $21^{\circ}C$. At the larger juvenile stage, $F_1$, weighing 3.7 g, there was no significant difference in SGR or FE among the diets, but RSB weighing 4.0 g fed 60/7, 55/12, and 51/17 diets had higher SGR and FE than 46/23 and 41/28 diets at $24^{\circ}C$. Moreover, survival and apparent nutrient retention of $F_1$ at both stages were significantly higher than those in RSB. These results indicate that both $F_1$ and RSB weighing ca. 0.3 g require a higher dietary CP/CL than those weighing ca. 4 g. Additionally, $F_1$ in both trials showed the suitability of a lower dietary CP/CL than RSB, indicating that mass production of $F_1$ juveniles will be more economical than RSB.

참다랑어(Thunnus orientalis)의 배합사료 개발을 위해 전갱이(Trachrus japonicus) 근육 합성 엑기스(SE)를 사용하여 omission test를 통해 섭이촉진물질을 검색하였다. 인공종묘 생산된 참다랑어 치어(평균체중 $9.0{\pm}0.91\;g$: 실험 1, 2, 3; $1.6{\pm}0.23\;g$: 실험 4)를 사용하여 전갱이 근육 100 g 상당 함량의 각각의 섭이촉진 물질을 카제인 기초 사료에 첨가하여 총 4회의 사육실험을 실시하였다. 실험 1에서 인공합성엑기스(SE)와 SE로부터 아미노산 관련 화합물(SE-A), 핵산관련물질(SE-N) 그리고 유기염기화합물(SE-O)을 각각 제외한 시험액을 제조하여 천연 전갱이 근육 엑기스(NE)와 비교한 결과, SE-A와 SE-N구는 SE보다 낮은 섭이활성을 보였으나, SE-O구는 SE와 유사한 섭이활성을 보였다. 실험 2에서는 IMP가 섭이 촉진에 가장 많은 영향을 미치는 것이 인정되었으며, 실험 3에서는 L-alanine, L-glutamic acid, L-histidine, L-lysine, taurine 그리고 IMP의 혼합물이 SE와 섭이활성의 차이를 보이지 않았다. 실험 4에서는 L-histidine, L-glutamine 그리고 IMP 혼합물이 가장 높은 섭이활성을 보였으며, 그 다음으로는 SE, L-lysine, L-alanine and IMP 혼합물, L-histidine, L-glutamic acid, L-lysine and L-alanine과 IMP의 혼합물이 높은 섭이활성을 보였다. 본 연구결과 참다랑어 치어의 유효 섭이촉진물질은 L-histidine, L-glutamic acid 그리고 IMP로 판단되었다. For establishing a basal diet for the Pacific bluefin tuna Thunnus orientalis (PBT), feeding stimulants were initially identified by omission test using the synthetic extract of horse mackerel, Trachurus japonicus. Four feeding trials were conducted using juvenile PBT weighing $9.0{\pm}0.91\;g$ (trial 1, 2 and 3) and $1.6{\pm}0.23\;g$ (trial 4), which were originated from an artificial seedling production. The fish fed the casein diet with each test solution were added at the ratio of 100 g casein diet to 100 g jack mackerel muscle. A complete synthetic extract of jack mackerel containing all 3 fractions, amino acid, nucleotide and organic nitrogenous base, exhibited a comparable feeding stimulant activity compared to that of natural extract. The omission of nucleotide or amino acid fraction showed lower feeding activity, but the omission of other nitrogenous fraction maintained a similar feeding stimulant activity compared to that of the synthetic extract (trial 1). Inosine-5' monophosphate $Na_2$ (IMP) was identified as a major constituent for maintaining feeding activity. The mixture of L-alanine, L-glutamic acid, L-histidine, L-lysine, taurine and IMP induced a similar feeding activity compared to that of the synthetic extract (trial 2 and 3). In trial 4, the highest feeding activity was finally obtained in the mixture of L-histidine, L-glutamine and IMP, followed by the synthetic extract, the mixture of L-lysine, L-alanine and IMP, IMP and the mixture of L-histidine, L-glutamic acid, L-lysine and L-alanine. These results revealed that the mixture of L-histidine, L-glutamic acid and IMP for the proper feeding stimulant of PBT in this study.

To determine a suitable dietary protein/lipid (CP/CL) ratio in the early juvenile stages of hybrid porgy (F1), female red sea bream (RSB) × male black sea bream, five diets with various CP/CL ratios「60/7, 55/12, 51/17, 46/23, and 41/28」were prepared and provided to juveniles in triplicate. At the smaller juvenile stage, F1, weighing 0.32 g, a significantly higher specific growth rate (SGR) and feed efficiency (FE) were seen with 60/7 and 55/12 diets. However, in RSB weighing 0.26 g, SGR and FE were higher with the 60/7 diet than the other diets at 21°C. At the larger juvenile stage, F1, weighing 3.7 g, there was no significant difference in SGR or FE among the diets, but RSB weighing 4.0 g fed 60/7, 55/12, and 51/17 diets had higher SGR and FE than 46/23 and 41/28 diets at 24°C. Moreover, survival and apparent nutrient retention of F1 at both stages were significantly higher than those in RSB. These results indicate that both F1 and RSB weighing ca. 0.3 g require a higher dietary CP/CL than those weighing ca. 4 g. Additionally, F1 in both trials showed the suitability of a lower dietary CP/CL than RSB, indicating that mass production of F1 juveniles will be more economical than RSB.
