For several days, there was a series of mortalities of chub mackerel (Scomber japonicus) that were reared for public exhibition in a private aquarium in Seoul, Korea. As part of the diagnosis of the dead fish, a bacterial isolate from the kidney was cultured, identified, and confirmed to be Vibrio (V.) harveyi using Vitek System 2 and 16S rRNA gene sequencing. Phylogenetic analysis was also performed by the neighbor-joining method. As a result, the V. harveyi isolated from chub mackerels of a private aquarium in Korea, called as SNUVh-LW1, was clustered in the same group with V. harveyi ATCC33843.

This study was performed to analyze the velocity and temperature distributions of the land aquaculture tank for fish breeding. In this study, we analyzed the velocity and temperature distributions in aquarium tank, and the finite volume method and standard ${\kappa}-{\epsilon}$ turbulence model with the SIMPLE computational algorithm are used to study the water flow in the aquarium. The main calculation parameters of the aquarium tank are the inlet flow rate with from 0.5 to 2.0L/M.

The zebra shark Stegostoma fasciatum which had been reared in the commercial aquaria was found dead and submitted for postmortem examination. A pure bacterial culture was isolated from pale and enlarged liver. The analysis of ureC and 16S rRNA genes confirmed the isolate as Photobacterium (P.) damselae subsp. damselae and this pathogen was sensitive to gentamicin. Although, no mortality in mouse was observed in the experimental infection study, the isolation of this pathogen in aquarium fish is significant because it can act as a reservoir to other aquatic animals and can also be zoonotic potential to human during aquarium management. This paper describes the first isolation of P. damselae subsp. damselae from zebra shark.

Nineteen rockfishes representing two species in the family Scorpaenidae were collected from Oregon Coast Aquarium in July 2003 and examined for parasitic copepods. The parasitic copepods were taken from the gills of Sebastes crameri and fins of S. melanops. With regard to the prevalence of copepod 22.2% of the fishes were infected by C. uncinata, and 30.0% by N. robusta. Intensity of infections of Clavella uncinata to Sebastes melanops, showed a range of 4 to 6 with a mean of 5.0 per fish while Neobrachiella robusta to S. crameri was 1 to 6 with a mean of 2.7.

Gradual mortality of look down fish (Selene vomer) was observed in a private aquarium in Seoul, showing abnormal swimming behavior and lethargy. A bacterial pathogen from kidney was cultured, identified, and confirmed as Vibrio harveyi using Vitek System 2 and 16S rRNA gene sequencing. A predominant bacterial strain, SNUVh-LW2 was proved to be most closely related to isolates from China by phylogenetic analysis with minimum evolution method. Also, tetracycline was considered as the most sensitive antibiotic agent via antibiotic susceptibility test. The group of fish was treated according to the diagnostic result and no more mortality was observed.

We have launched an investigation for Embryonic Development, Larvae and Juvenile Morphology, of Buenos aires tetra in order to build basic data of Characidae and fish seeding production. We brought 50 couples of Characidae from Bizidduck aquarium in Yeosu-si, Jeollanamdo, from Korea on March of 2015. We put them in the tetragonal glass aquarium ($50{\times}50{\times}30cm$). Breeding water temperature was $27.5{\sim}28.5^{\circ}C$ (mean $28.0{\pm}0.05^{\circ}C$) and being maintained. The shape of fertilized egg was round shape, and it was adhesive demersal egg. The egg size was 0.63~0.91 mm (mean $0.74{\pm}0.07mm$, n=20). After getting fertilized egg, the developmental stage was gastrula stage, and embryo covered almost two-thirds of Yolk. Incubation was happened after 16 hours 13 minutes from gastrula stage, and the tail of juvenile came out first with tearing egg capsule. Immediately after the incubation, prelarvae had 3.78~3.88 mm length (mean $3.84{\pm}0.04mm$, n=5), and it had no mouth and anus yet. 34 days after hatching from the incubation, juvenile had 8.63~13.1 mm (mean $10.9{\pm}1.66mm$), and it had similar silver-colored body shape with its mother.

순환여과수조에 있어 수질 오염의 지표로서 대장균군의 수적인 변동을 측정하였다. 세균의 오염은 주로 어류의 먹이와 배설물 그리고 새로 교환되는 사육수의 기오염도에 원인이 있었다. 수조내의 세균량은 수질의 물리화학적인 요인에 의해서 조절되었으며, 이러한 요인들 중에서는 pH가 주된 것이었다. 수온 $20^{\circ}C$에 pH가 $5\~6$ 이하로 낮아질 경우에는 세균의 급격한 번식은 없었다. 수온이 $30^{\circ}C$ 이상 일 때 세균의 성장은 pH에 관계없이 현저하게 감소하였으며, 세균군은 그 이하의 온도에서 활발히 성장하는 것처럼 보였다.

The effect of the hydraulic residence time (HRT) for the removal of aquarium waste, such as protein, total suspended solids (TSS) and turbidity were investigated by using a foam separator Protein, TSS and turbidity removal efficiencies were increased with the increase of hydraulic residence time. The optimum hydraulic residence time was 0.5 min, and the highest protein and TSS removal rates were $14.4\;g/L{\cdot}day\;and\;38.9\;g/L{\cdot}day,$ respectively. The tendency of turbidity removal rate and efficiency was similar to that of protein.

1979년 8월 태국에서 Clarias batrachus 자어 100미를 도입하여 그 중 10미를 제주대학양식학과양어실험실에서 친어까지 사육하였다. 성장은 자어에서 29일후 체장 5cm 전후 체중 1.43g으로 성장하였고, 260일후에는 약 206g으로 성장하였다. 1980년 10월 11일 3미의 암컷에 Chorionic gona-dotrophin $1\sim2\;IU$ 씩 주사하여, 그 중 1미가 10월14일에 산난하여 약 1,500개의 수정난을 얻었고 22시간 후 완전히 부화하여 그후 먹이를 갈 먹고 자란 건강한 자어 약 1,300미를 얻었다.

Effect of initial protein concentration on the protein removal rate was assessed for seawater aquarium using a foam separator. Protein removal rate was increased and removal efficiency was decreased with the increase of initial protein concentration. Enrichment ratio was decreased and foam generation rate was increased with the increase of initial protein concentration. Total suspended solids (TSS) removal rate was increased with the increase of initial protein concentration, and TSS removal efficiency was decreased with the increase of initial protein concentration. Turbidity removal rate and removal efficiency were increased with the increase of initial protein concentration.
