We used two methods of electric stimulation, one is the Electric Field Experiment (EFE) and the other is the Partial Electric Field Experiment (PEF). The responses of three species of sharks, Carcharhinus falciformis (60 cm TL), Triaenodon obesus (119 cm TL), and Stegostoma fasciatum (220 cm TL), to the EFE electric stimulation were studied. The captive sharks swam in a circular tank (7m in diameter, 1.2 m in depth). The source unit consisted of a signal generator, which produced the wave form, frequency, and voltage, and a power amplifier. Electrodes were 5 cm × 10 cm copper plates, separated by a distance of 3.5 m. A 60 Hz sine wave and DC pulse electric fields were chosen. The 60 Hz sine wave was 1 V to 10 V (r.m.s) and the DC pulse period was either 1 sec or 5 sec (duty ratio is 10%). All sharks swam close to the side of the tank when the signal generator was off. When the 60 Hz sine wave and DC pulse electric field were being produced, two species, C. falciformis and T. obesus, immediately turned around. The sharks were demonstrated a high rate of turning when exposed to the DC pulse electric fields. Conversely, S. fasciatum did not change its swimming patterns when the signal generator was on. The PEF was conducted for eight species; three species were same the individuals tested in the EFE plus five additional species: Galeocerdo cuvier (218 cm TL), Carcharhinus melanopterus (65 cm TL), Triakis scyllium (64 cm TL), Cephaloscyllium isabellum (53 cm TL), and Scyliorhinus torazame (42 cm TL). Electrodes were separated by a distance of 30 cm or 2 cm. Four species, C. melanopterus, C. falciformis, T. obesus, and T. scyllium, gave a strong response to the electric field, two species, C. isabellum and S. torazame, gave a weak response to the electric field, but two other species, G. cuvier and S. fasciatum, did not show a response to the electric field. Hence, the behavioral response patterns were different among the species. Objectives of the study include the results of the behavioral responses of sharks to electric stimulation and examination of the possibility of electric fields for repellence from shark attacks and protection from shark depredation of fisheries.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"電界印加実験および局部電界発生実験(電撃実験)を用いて,電気刺激に対するサメ類の反応について研究を行った.電界印加実験(EFE)は,クロトガリザメ,ネムリブカ,トラフザメの3種類で行った. 実験方法は,直径7メートルの円形水槽の中心部と縁辺部に銅板電極を設置し,電流を流して実験魚の遊泳行動の観察を行った.実験は方形波パルスと 60Hz 正弦波交流を電力増幅し,電極間に印加した. 電界印加実験は1回の実験につき10分間行い,ビデオカメラによる撮影と目視による行動観察を行った. 3種類の実験魚の通常の遊泳行動は,円形水槽の縁に沿って遊泳していた. クロトガリザメとネムリブカは,電界印加を与えたところ,頭部を左右に振り急激な方向変換をし,その回数は通常の遊泳行動よりも多かった. そして,電極付近には近づかず,電極間もほとんど通過することがなく,これら2種は電界を嫌う行動がみられた. 一方,トラフザメは電界印可を行っても遊泳行動に変化が現れることがなかった.局部電界発生実験(PEF)は,EFEの実験魚3種とイタチザメについては円形水槽で,ツマグロ,ドチザメ,ナヌカザメ,トラザメでは長方形水槽(180cm×120cm×70cm)で実験を行った.クロトガリザメ,ツマグロ,ネムリブカ,ドチザメは,電撃刺激に対して非常に強い逃避行動の反応がみられた. ナヌカザメとトラザメでは,電撃刺激に対して頭部をほんの僅か振る程度の非常に弱い反応があり,逃避行動もみられなかった. イタチザメとトラフザメは電撃刺激に対してまったく反応しなかった.以上のように電気刺激に対して非常に強い逃避行動がみられる種類もいるが,まったく反応しない種類もみられ,これら刺激に対する反応には種類別に違いがあることが判明した.そのため,電気刺激に対する反応が強い種類では,サメ類の人的被害防止あるいは漁業への食害防止のために電気刺激を利用できることが示唆された.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai
