[problem] seaweed farms of sea conditions (sea water cleanliness, sea water temperature, etc.), state and properties, such as algae attached to the laver network and it subjected to active treatment, is carried out active treatment for such variations of the active treating agent concentration in the treatment tank during corresponds at any time while performing the seaweed network activation treatment, seaweed network activity process which makes it possible to perform more appropriate laver network activation treatment to provide a laver network activity processing ship is equipped automatic feeding device and this agent. Supply supplies and continuous supply of A active treatment agent by the automatic supply means for supplying a time set by the supply amount per unit set time continuously active treating agent, an active treatment agent hoses 20a, any amounts per unit time of the supplied active treatment agent by manually opening and closing control cock valve that is deployed at a position linked with the active treating agent tank 18 and 20b and the feed pump 40 It was to arbitrarily switch between continuous supply of controlledFIELD 2【課題】海苔養殖場の海の状況(海水の汚れ具合、海水温、等々)、活性処理を施す海苔網やそれに付着している藻類などの状態・性状、活性処理を行っている間における処理槽中の活性処理剤濃度の変動などに対して、海苔網活性処理を行っている最中に随時対応し、より適切な海苔網活性処理を行うことを可能にする海苔網活性処理剤の自動供給装置及びこれを備えている海苔網活性処理船を提供する。【解決手段】設定された単位時間あたりの供給量で設定された時間連続して活性処理剤を供給する自動供給手段による活性処理剤の連続供給と、活性処理剤を供給する供給ホース20a、20bの活性処理剤タンク18と供給ポンプ40とを連結している箇所に配備されているバルブのコックを手動で開閉制御することで供給する活性処理剤の単位時間あたりの量を任意的に制御する連続供給とを任意に切り替え可能にした。【選択図】図2
