Description
この発明によれば、電極間に位置する魚介類に正弦波電流が負荷される(流される)。
この発明によれば、魚介類が電極間のいずれに位置していても、電流密度がほぼ均一な正弦波電流が魚介類に負荷される。
図1は、この実施の形態に係る魚介類の飼育装置(以下、適宜「飼育装置」という)1の概略構成ブロック図である。この飼育装置1は、魚(魚介類)Tを飼育する装置であって、主として、水槽2と、電極3と、電源(電流負荷手段)4と、絶縁変圧器(電流負荷手段)5と、電流制限回路(均一化手段)6とを備えている。
図8は、この実施の形態に係る魚介類の飼育装置10の概略構成ブロック図である。この実施の形態では、電源4の代わりに、発電機(電流負荷手段)7および蓄電池(電流負荷手段)8を備えている点で実施の形態1と構成が異なり、実施の形態1と同等の構成については同一符号を付して説明する。
図9は、この実施の形態に係る魚介類の飼育装置20の要部構成図である。この飼育装置20は、沖だしと呼ばれる海洋での養殖に使用される装置であり、実施の形態1と同等の構成については同一符号を付して説明する。また、電極3から電流制限回路6側の構成については、実施の形態1または2と同等の構成であるため、説明を省略する。
図10、11は、この実施の形態に係る魚介類の飼育装置30の要部構成図である。この飼育装置30では、養殖いかだ21と養殖網22とを複数組備えている点で実施の形態3と構成が異なり、実施の形態3と同等の構成については同一符号を付して説明する。
図12は、この実施の形態に係る魚介類の飼育装置40の要部構成図である。この飼育装置40では、タップ付絶縁変圧器(均一化手段)41を備えている点で実施の形態4と構成が異なり、実施の形態4と同等の構成については同一符号を付して説明する。
