He is the professor of the Division of Marine Production System Management, Pukyong National University. He has published more than 76 papers in reputed journals and has been serving as an editorial board member of repute.
Abstract:
In order to collect basic information of migration of rockfish (Sebastes schlegeli), the behaviors of rockfish during summer in Byonsan Peninsular located at the coastal of Yellow Sea, Korea were investigated. Three cultured rockfishes CR1 to CR3 [total length (TL) 33.0±1.0 cm; body weight 493±32 g] were tagged with the acoustic tag. CR1 and CR2 were tagged externally with the acoustic tag. CR3 was tagged with an acoustic tag internally by surgical method. The movement routes of the tagged fish were tracked within 2 hours approximately using VR100 receiver and a directional hydrophone. Three tagged fishes (CR1, CR2 and CR3) were individually released on the sea surface far away about 500 m from a construction site of wind power on the sea in the coastal of Byeonsan Peninsular on 9 May, 21 May and 18 August 2017, respectively. CR1 and CR2 were moved so fast and lost the signal from the acoustic tags within 8 and 12 minutes, respectively, after release. CR2 was released during piling work on 21 May 2017. CR1 and CR2 were released during without piling work. The water depth of the sea bed on the route of CR1 and CR2 were commonly 9.8 to 11.0 m. CR3 was moved about 4.32 km with average swimming speed of 0.58 m/s (1.69 TL/s) during 2.1 hours. The mean angle of the movement direction of RC2 was 291°, and the water depth on the route, 10.0 to 12.0 m. There was no significant correlationship (Pearson correlation, p= 0.447, p>= 0.05) between the tidal current direction and the movement direction of CR3.

Abstract:
Nowadays ornamental fish keeping is one of the most popular hobbies in the world. The growing interest in aquarium fishes has resulted in steady increase in aquarium fish trade globally. The trade with a turnover of US $ 5 Billion and an annual growth rate of 8 percent offers a lot of scope for development. The top exporting country is Singapore followed by Honkong, Malaysia, Thailand, Philippines, Srilanka, Taiwan, Indonesia and India. Majority of the indigenous ornamental fish trade in India is from the North Eastern states and the rest is from Southern states. The economic importance of ornamental fisheries has been recognized by many developing countries for employment generation and livelihoods. India's share in ornamental fish trade is estimated to be Rs 158.23 lakh which is only 0.008% of the global trade. The major part of the export trade is based on wild collection. The domestic market in India is mainly based on domestically bred exotic species. Nagaland is endowed with hill streams and rivers which harbor endemic fish fauna including ornamental fish. Nagaland has a richness of natural resource such as suitable climate, natural rivers and traditional experience in the culture of fishes so farmers can readily culture ornamental fishes. Nagaland has a great variety of colorful indigenous ornamental fishes and has been found that aqua-systems contains as many as 118 endemic fresh water ornamental fish biodiversities constituting 79.19% of total fish inhabitant. Ornamental Fish Species of Nagaland may be broadly grouped into Non-classified (48 species) and classified (70 species) categories constituting respectively 40.68% and 50.32 % of total ornamental fish species germplasm. This paper discuss present status of ornamental fish culture in Nagaland and its future prospects.
