A single specimen of Albula leptocephalus (55.7 mm SL) was collected from the southern coastal waters of Korea using an aquatic lamp. It is characterized by having a ribbon-like body with a small head and a well-forked caudal fin. Although the general appearance was similar to the leptocephalus of A. vulpes including myomere counts and fin ray counts, the melanophore deposition was different from that of A. vulpes. This leptocephalus specimen was confirmed with A. forsteri using the cytochrome b mtDNA (Cytb) analysis. The genetic distance of Cytb between the present leptocephalus and A. forsteri is 0.006-0.038, which falls into the cutoff point separating Albula species into eight deep lineages including the four valid species. Its genetic characteristic have more similarities to those of Fiji than those of Hawaii and the Northern territory of Australia.

To identify and compare the nutritional composition of different kinds of citrus, three examples (Citrus fruit, Kumquat, and Hallabong) were taken from Jeju island in Korea at the same time and their nutritional compositions were measured using the Association of Official Analytical Chemists (AOAC) method. The proximate components (moisture, protein, fat, fiber, ash, and carbohydrates), mineral and vitamin contents were measured. The Nutrient composition revealed some significant differences among the Citrus. The Citrus fruit has more moisture and Fe content than those of the Kumquat. The Kumquat contained more ash, Ca, Na, Mg, Zn, Vitamin A, and B1 than the other Citrus specimens, while the Hallabong had the most protein and Fe. However, fiber, K, Vitamin B₂, C and niacin contents were not significantly different among the specimens. The results demonstrate that the three kinds of citrus used in this study have different nutritional compositions, but they can all be used as a good food for supplementation of K, vitamin A and C. We hope the nutritional analysis of Citrus specimens will be helpful in meeting the consumer's interest in these Citrus, and increase the export of our Citrus produce.

Growth performances of the selected and the non-selected red sea bream (Pagrus major) lines were evaluated up to marketable size. The offspring were mass-produced either from the selected line (the fourth generation of broods from mass selection) or the non-selected line (the second generation of wild broods). Early (59 to 103 days old, trial I) and late growth performances (4 to 24 months old, trial II) were evaluated based on communal rearing in land-based tanks and sea cages, respectively. In trial I, the selected line exhibited significantly higher values in both weight gain (WG) and specific growth rate (SGR) when compared to those observed in the non-selected line (P<0.05). In trial II comprising of three growth phases (4-9, 9-16 and 16-24 months old), selected line showed only slightly improved in WG and SGR at the beginning two growth phases (4-9 and 9-16 months old) (P>0.05), however, displayed significantly higher values at the last growth phase (16-24 months old) (P<0.05). Overall WG and SGR throughout the experiment (4-24 months) were also significantly higher in the selected line than the non-selected line (P<0.05). Consequently, mean body weight of the selected line at 24 months old was 1.4-fold (40.8{\%}\;increased) as compared to that of the non-selected line. This present result indicates that mass selection of this species against the growth traits might be quite effective, and the present advance has important Implication in the productivity enhancement of red sea bream aquaculture.
