Totally, twenty seven specimens of tiger puffer, Fugu rubripes rubripes were collected at Jagalchi fish market in Pusan, Korea during January, April and September in 1995. Anatomical distribution of pufferfish toxin in tiger puffer was examined by mouse bioassay. The frequency rate of toxic specimens containing ≥ 10 MU/g was 14.8% in liver; 16.7% in gonad; and 14.8% in skin, and no toxin was detected in muscle. The highest toxin level found was 160 MU/g in liver, 600 MU/g in gonad and 26 MU/g in skin, and each average toxin level (mean ± standard error) was 7 ± 6, 50 ± 35 and 5 ± 1 MU/g, respectively. Some specimens collected in January and April were toxic, while none of the specimens collected in September showed its toxicity. Although toxicity of tiger puffer showed the seasonal variation, tested tiger puffer was evaluated as a safe seafood for consumption, in that an acceptable level of toxin was found in the edible muscle and skin.

본 연구는 부산을 대표하는 수변공간으로서, 인지도가 높은 7곳(해운대, 민락공원, 광안리, APEC나루공원, 다대포, 자갈치, 태종대)을 선정하여 사전 표본 설문조사를 실시하였다. 그 결과를 바탕으로 특성이 가장 뚜렷하게 나타난 2곳(해운대, 자갈치)을 대상으로 설문조사를 다시 실시하여, 방문자가 수변공간에 대해서 느끼는 수변공간의식을 조사하였다. 그 결과, 해운대는 이용자의 81.5%(163명)가 '바다바람을 느낀다.'로 응답하였으며, 자갈치는 55.8%(111명)가 '해산물을 먹을 수 있다.' 로 응답하였다. 또 수변공간의식을 중심으로 각각 연령대별, 희망 활동별로 수변공간의 전체적인 만족도에 대한 분석을 실시하였다.
