유수식 수조 실험을 통한 통합형과 은신처형 해삼(Apoctichopus japonicus, selenka) 양성기구의 생물학적 성능 평가

다국어 초록 (Multilingual Abstract)

A series of experiments were conducted to evaluate biological performances of three types of rearing systems for sea cucumber grow-out in indoor seawater tank of chonnam national university for 61 days (5. 29 - 7. 30. 2013). The cage models were made of polypropylene pipe for the frames. The size of the cage models were 920L×570B×500D ㎜, composed PE eel pots (hiding place: Ф130 ㎜×21 pieces, total volume: 0.51 m³) in TC, and 110L×800B×500D ㎜, constructed of PVC pipes (hiding place: Ф130 ㎜×21 pieces, total volume: 0.27 m³)in DC and UC(440L×460×620 ㎜ volume: 0.13 m³). In Experiment TC, DC and TC models were set up in the flow - through tank (7000L×6000B×820D ㎜, water depth: 0.82 m) at Chonnal National University, Yeosu, Korea for period of 99 days (17 July to 22 April 2013). In Experiment, a total 200 sea cucumbers were used, with an initial body wet weight of 64.68 ± 33.94 g. The water temperatures ranged from 10.88 to 16.65℃, and salinity ranged from 34.68 to 32.26 psu.
Sea cucumbers were fed a mixed diet(mud, mineral, fish meal, etc.) and the feed was supplied to 3% of the weight. The results of an experiment (e.g. biological parameters) were analyzed with the statistical computer package SPSS ver. 21 from IBM.
In Experiment, the survival rates of sea cucumber in UC (100%) and DC (87.62%) were higher than those of the TC (48.57%). The specific growth rate (SGR) of sea cucumber cages in DC (0.19%day<SUP>-1</SUP>) SGR was slightly higher than those UC (-0.25%day<SUP>-1</SUP>) results.
The next step is to conduct indoor water tank test in order to investigate whether or not the rearing systems could be incorporated effectively for sea cucumber aquaculture industry. considering the season and the stocking densities of sea cucumber reared in the systems.
